Reduction in baroreflex cardiovascular responses due to venous infusion in the rabbit. (1/3107)

We studied reflex bradycardia and depression of mean arterial blood pressure (MAP) during left aortic nerve (LAN) stimulation before and after volume infusion in the anesthetized rabbit. Step increases in mean right atrial pressure (MRAP) to 10 mm Hg did not result in a significant change in heart rate or MAP. After volume loading, responses to LAN stimulation were not as great and the degree of attenuation was propoetional to the level of increased MRAP. A change in responsiveness was observed after elevation of MRAP by only 1 mm Hg, corresponding to less than a 10% increase in average calculated blood volume. after an increase in MRAP of 10 mm Hg, peak responses were attenuated by 44% (heart rate) and 52% (MAP), and the initial slopes (rate of change) were reduced by 46% (heart rate) and 66% (MAP). Comparison of the responses after infusion with blood and dextran solutions indicated that hemodilution was an unlikely explanation for the attenuation of the reflex responses. Total arterial baroreceptor denervation (ABD) abolished the volume-related attenuation was still present following bilateral aortic nerve section or vagotomy. It thus appears that the carotid sinus responds to changes inblood volume and influences the reflex cardiovascular responses to afferent stimulation of the LAN. On the other hand, cardiopulmonary receptors subserved by vagal afferents do not appear to be involved.  (+info)

Of them, 34 (37%) had an abnormal alanine-aminotransferase (ALT) baseline pattern, and the other 12 (13%) showed ALT flare-ups during the follow-up. TTV DNA in patient sera collected at the time of enrollment and at the end of follow-up was determined by polymerase chain reaction (PCR). In parallel, serum samples from 100 healthy blood donors were also tested. At baseline, 87 patient sera (93.5%) tested positive for the TTV DNA. Of these TTV DNA-positive patients, 84 (96.5%) remained viremic at the end of the study period. Of the 6 TTV DNA-negative patients, 3 acquired TTV infection during follow-up. However, no definite relation was observed between the results of TTV DNA determination and ALT patterns. TTV viremia was also detectable in 22% of blood donors. In conclusion, TTV infection is frequent and persistent among Italian transfusion-dependent patients. The high rate of viremia observed in healthy donors indicates that the parenteral route is not the only mode of TTV spread.  (+info)

Soluble HLA class I, HLA class II, and Fas ligand in blood components: a possible key to explain the immunomodulatory effects of allogeneic blood transfusions. (3/3107)

The immunomodulatory effect of allogeneic blood transfusions (ABT) has been known for many years. However, a complete understanding of the effects of ABT on the recipient's immune system has remained elusive. Soluble HLA class I (sHLA-I), HLA class II (sHLA-II), and Fas ligand (sFasL) molecules may play immunoregulatory roles. We determined by double-determinant immunoenzymatic assay (DDIA) sHLA-I, sHLA-II, and sFasL concentrations in different blood components. sHLA-I and sFasL levels in red blood cells (RBCs) stored for up to 30 days and in random-donor platelets are significantly (P <.001) higher than in other blood components and their amount is proportionate to the number of residual donor leukocytes and to the length of storage. Blood components with high sHLA-I and sFasL levels play immunoregulatory roles in vitro as in allogeneic mixed lymphocyte responses (MLR) and antigen-specific cytotoxic T-cell (CTL) activity, and induce apoptosis in Fas-positive cells. These data suggest that soluble molecules in blood components are functional. If these results are paralleled in vivo, they should be taken into account in transfusion practice. Blood components that can cause immunosuppression should be chosen to induce transplantation tolerance, whereas blood components that lack immunosuppressive effects should be preferred to reduce the risk of postoperative complications and cancer recurrence.  (+info)

Structural and functional consequences of antigenic modulation of red blood cells with methoxypoly(ethylene glycol). (4/3107)

We previously showed that the covalent modification of the red blood cell (RBC) surface with methoxypoly(ethylene glycol) [mPEG; MW approximately 5 kD] could significantly attenuate the immunologic recognition of surface antigens. However, to make these antigenically silent RBC a clinically viable option, the mPEG-modified RBC must maintain normal cellular structure and functions. To this end, mPEG-derivatization was found to have no significant detrimental effects on RBC structure or function at concentrations that effectively blocked antigenic recognition of a variety of RBC antigens. Importantly, RBC lysis, morphology, and hemoglobin oxidation state were unaffected by mPEG-modification. Furthermore, as shown by functional studies of Band 3, a major site of modification, PEG-binding does not affect protein function, as evidenced by normal SO4- flux. Similarly, Na+ and K+ homeostasis were unaffected. The functional aspects of the mPEG-modified RBC were also maintained, as evidenced by normal oxygen binding and cellular deformability. Perhaps most importantly, mPEG-derivatized mouse RBC showed normal in vivo survival ( approximately 50 days) with no sensitization after repeated transfusions. These data further support the hypothesis that the covalent attachment of nonimmunogenic materials (eg, mPEG) to intact RBC may have significant application in transfusion medicine, especially for the chronically transfused and/or allosensitized patient.  (+info)

Endoscopic retreatment compared with surgery in patients with recurrent bleeding after initial endoscopic control of bleeding ulcers. (5/3107)

BACKGROUND AND METHODS: After endoscopic treatment to control bleeding of peptic ulcers, bleeding recurs in 15 to 20 percent of patients. In a prospective, randomized study, we compared endoscopic retreatment with surgery after initial endoscopy. Over a 40-month period, 1169 of 3473 adults who were admitted to our hospital with bleeding peptic ulcers underwent endoscopy to reestablish hemostasis. Of 100 patients with recurrent bleeding, 7 patients with cancer and 1 patient with cardiac arrest were excluded from the study; 48 patients were randomly assigned to undergo immediate endoscopic retreatment and 44 were assigned to undergo surgery. The type of operation used was left to the surgeon. Bleeding was considered to have recurred in the event of any one of the following: vomiting of fresh blood, hypotension and melena, or a requirement for more than four units of blood in the 72-hour period after endoscopic treatment. RESULTS: Of the 48 patients who were assigned to endoscopic retreatment, 35 had long-term control of bleeding. Thirteen underwent salvage surgery, 11 because retreatment failed and 2 because of perforations resulting from thermocoagulation. Five patients in the endoscopy group died within 30 days, as compared with eight patients in the surgery group (P=0.37). Seven patients in the endoscopy group (including 6 who underwent salvage surgery) had complications, as compared with 16 in the surgery group (P=0.03). The duration of hospitalization, the need for hospitalization in the intensive care unit and the resultant duration of that stay, and the number of blood transfusions were similar in the two groups. In multivariate analysis, hypotension at randomization (P=0.01) and an ulcer size of at least 2 cm (P=0.03) were independent factors predictive of the failure of endoscopic retreatment. CONCLUSIONS: In patients with peptic ulcers and recurrent bleeding after initial endoscopic control of bleeding, endoscopic retreatment reduces the need for surgery without increasing the risk of death and is associated with fewer complications than is surgery.  (+info)

Primary percutaneous transluminal coronary angioplasty performed for acute myocardial infarction in a patient with idiopathic thrombocytopenic purpura. (6/3107)

A 72-year-old female with idiopathic thrombocytopenic purpura (ITP) complained of severe chest pain. Electrocardiography showed ST-segment depression and negative T wave in I, aVL and V4-6. Following a diagnosis of acute myocardial infarction (AMI), urgent coronary angiography revealed 99% organic stenosis with delayed flow in the proximal segment and 50% in the middle segment of the left anterior descending artery (LAD). Subsequently, percutaneous transluminal coronary angioplasty (PTCA) for the stenosis in the proximal LAD was performed. In the coronary care unit, her blood pressure dropped. Hematomas around the puncture sites were observed and the platelet count was 28,000/mm3. After transfusion, electrocardiography revealed ST-segment elevation in I, aVL and V1-6. Urgent recatheterization disclosed total occlusion in the middle segment of the LAD. Subsequently, PTCA was performed successfully. Then, intravenous immunoglobulin increased the platelet count and the bleeding tendency disappeared. A case of AMI with ITP is rare. The present case suggests that primary PTCA can be a useful therapeutic strategy, but careful attention must be paid to hemostasis and to managing the platelet count.  (+info)

Hormonal changes in thalassaemia major. (7/3107)

Patients with severe thalassaemia major suffer endocrine and other abnormalities before their eventual death from iron overload due to repeated blood transfusions. The endocrine status of 31 thalassaemic patients aged 2-5 to 23 years was investigated. Exact data were available on the rate and duration of blood transfusion in all of them and in many the liver iron concentration was also known. Although the patients were euthyroid, the mean serum thyroxine level was significantly lower, and the mean thyrotrophic hormone level significantly higher, compared with the values found in normal children. Forty oral glucose tolerance tests with simultaneous insulin levels were performed in 19 children, of whom 5 developed symptomatic diabetes and one had impaired tolerance. Previous tests on all 6 patients were available and some showed raised insulin levels possibly due to insulin resistance. 2 patients had clinical hypoparathyroidism and are described. The parathyroid hormone levels determined by radioimmunoassay in 25 patients were below the mean for the age group in all and outside the reference range in 16. Nonfasting plasma calcium levels were not reduced. Puberty was delayed in some patients. Concentrations of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) measured in urine from 7 girls and 5 boys showed considerable variation. In the boys there was an overall tendency for FSH and LH excretion to be low with regard to age, but with respect to puberty rating FSH exretions were normal or low and LH normal or raised. The girls showed a tendency for LH but not FSH excretion to be raised in relation to puberty rating. The severity of the endocrine changes was related to the degree of iron loading and is discussed in relation to previous work in which the iron loading has rarely been accurately indicated nor parathyroid status assessed.  (+info)

Prospective randomized multicenter study comparing cyclosporin alone versus the combination of antithymocyte globulin and cyclosporin for treatment of patients with nonsevere aplastic anemia: a report from the European Blood and Marrow Transplant (EBMT) Severe Aplastic Anaemia Working Party. (8/3107)

We report the results of the first prospective randomized multicenter study of immunosuppressive treatment in patients with previously untreated nonsevere aplastic anemia (AA) as defined by a neutrophil count of at least 0.5 x 10(9)/L and transfusion dependence. Patients were randomized to receive cyclosporin (CSA) alone or the combination of horse antithymocyte globulin ([ATG] Lymphoglobuline; Merieux, Lyon, France) and CSA. The endpoint of the study was the hematologic response at 6 months. One hundred fifteen patients were randomized and assessable with a median follow-up period of 36 months; 61 received CSA and 54 ATG and CSA. In the CSA group, the percentage of complete and partial responders was 23% and 23%, respectively, for an overall response rate of 46%. A significantly higher overall response rate of 74% was found in the ATG and CSA group, with 57% complete and 17% partial responders (P =. 02). Compared with CSA alone, the combination of ATG and CSA resulted in a significantly higher median hemoglobin level and platelet count at 6 months. Fewer patients required a second course of treatment before 6 months due to a nonresponse. In the CSA group, 15 of 61 (25%) patients required a course of ATG before 6 months because of disease progression, compared with only 3 of 54 (6%) in the ATG and CSA group. The survival probabilities for the two groups were comparable, 93% (CSA group) and 91% (ATG and CSA group), but at 180 days, the prevalence of patients surviving free of transfusions, which excluded patients requiring second treatment because of nonresponse, death, disease progression, or relapse, was 67% in the CSA group and 90% in the ATG and CSA group (P =.001). We conclude that the combination of ATG and CSA is superior to CSA alone in terms of the hematologic response, the quality of response, and early mortality, and a second course of immunosuppression is less frequently required.  (+info)

However, cancer occurrence in transfusion recipients remains poorly characterized. METHODS: We used computerized files from Scandinavian blood banks to identify a cohort of 888,843 cancer-free recipients transfused after 1968. The recipients were followed from first registered transfusion until the date of death, emigration, cancer diagnosis, or December 31, 2002, whichever came first. Relative risks were expressed as ratios of the ...
It turned out that Jai, who was a Thalassemic patient since he was just a year old, had contracted HIV through blood transfusion at the Junagadh Civil Hospital. And it wasnt just him; 35 other Thalassemic children being given transfusion at the same hospital had become HIV-infected. Of them, eight died.. All our happiness died with our child. Who do we live for now? said 50-year-old Rafeeq Ranava, Jais father, a daily-wage labourer in Junagadh.. An IndiaSpend investigation, through a series of Right to Information (RTI) requests, has revealed that 14,474 cases of HIV through blood transfusion have been reported in India over the last seven years. It also revealed that the Indian government has yet to order a study or inquiry into this medical crisis that puts millions of lives at risk.. Not just that, there has been a 10 per cent rise in the number of such cases over the last one year - from 1,424 in 2014-15 to 1,559 in 2015-16 - according to documents obtained from that National AIDS ...

Monthly blood transfusions may lower the chances of silent strokes in some children with sickle cell anemia, a new clinical trial indicates.. The study, reported in the Aug. 21 issue of the New England Journal of Medicine, found that in children with a previous silent stroke, monthly blood transfusions cut the rate of future strokes by more than half.. The researchers said their findings support screening children with sickle cell for evidence of silent stroke - something that is not routinely done now.. Prior to this, there was no treatment, so the argument was, Why screen? explained Dr. James Casella, vice chair of the clinical trial and director of pediatric hematology at Johns Hopkins Childrens Center in Baltimore. Now we have a treatment to offer.. However, Casella also stressed that this study is a first step, not the last one.. Many questions remain, he said. A big one is, do the blood transfusions have to be continued for life?. Its possible the treatment could be ...

Blood transfusion is administered during many types of surgery, but its efficacy and safety are increasingly questioned. Evaluation of the efficacy of agents, such as desmopressin (DDAVP; 1-deamino-8-D-arginine-vasopressin), that may reduce perioperative blood loss is needed.To examine the evidence for the efficacy of DDAVP in reducing perioperative blood loss and the need for red cell transfusion in people who do not have inherited bleeding disorders.We searched for randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (2017, issue 3) in the Cochrane Library, MEDLINE (from 1946), Embase (from 1974), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (from 1937), the Transfusion Evidence Library (from 1980), and ongoing trial databases (all searches to 3 April 2017).We included randomised controlled trials comparing DDAVP to placebo or an active comparator (e.g. tranexamic acid, aprotinin) before, during, or immediately after surgery or after

HIV infection through blood transfusions is very rare in the US because all donated blood is carefully screened. Please select the best answer from the choices provided. T F
Not really no. Most blood transfusions we think about are red blood cells or platelets, which dont have the immune function youre asking for. Thats a good thing. Usually, if there are white blood cells in the transfused blood, the hosts immune system will recognize them as foreign and destroy them. Remember, your cells all look like foreign invaders to my cells; blood transfusions of red blood cells are carefully matched to limit negative reactions. There is also a process called transfusion-associated graft versus host disease in which the donor white blood cells will attack the host cells; this mainly occurs in immune-compromised individuals, but GvHD is definitely something to avoid. Blood transfusions are usually filtered and irradiated to remove, among other things, white blood cells.. That being said, people are beginning to use white blood cells as treatment. A new therapy being studied heavily for all sorts of diseases, from cancer to HIV, is to take the hosts own white blood cells ...
Transfusion of washed intra-operative cell salvage post-operatively in the PCICU can be performed safely without increased risk of bleeding or release of inflammatory mediators. This will reduce the need for allogeneic blood products as well as crystalloid and colloid infusions and thus decrease the length of ventilation and intensive care duration for these infants ...
by Vetscite. Blood transfusions are one of the most common procedures patients receive in the hospital but the more red blood cells they receive, the greater their risk of infection, says a new study led by the University of Michigan Heath System and VA Ann Arbor Healthcare System. Researchers analyzed 21 randomized controlled trials for the study that appears in Journal of the American Medical Association (JAMA). Elderly patients undergoing hip or knee surgeries were most susceptible, with a 30 percent lower risk of infection when fewer transfusions were used. Overall, for every 38 hospitalized patients considered for a red blood cell transfusion (RBC), one patient would be spared a serious infection if fewer transfusions were used. Transfusions are often used for anemia or during surgery to make up for blood loss. The authors evaluated all health care-associated infections that were reported after receiving donor blood in the randomized trials. These included serious infections such as ...
As French physicians frequently and currently deployed in Theater of Operations in Africa, we read with interest the article by Ariyo et al.1 reviewing the anesthesia care provided at Médecins Sans Frontières facilities between 2008 and 2014. Spinal anesthesia was the most common type of anesthetic technique (34,413 [45.56%]), with cesarean section being the most common type of procedure performed (26,091 [34.54%]). Wound surgeries represented another common procedure type included in this retrospective study (18,547 [24.55%]). In this context, perioperative deaths occurred in 72 (0.21%) cases of obstetrics/gynecology and urology surgery and in only seven (0.06%) cases of wound surgeries. Nevertheless, the authors did not provide any details regarding the causes of death or any details about the incidence of perioperative bleeding and perioperative blood management. Perioperative blood management refers to perioperative blood transfusion and adjuvant therapies.2 Perioperative blood transfusion ...

Background: Despite the minimally invasive nature of trans-catheter aortic valve implantation (TAVI), the procedure is associated with several complications. We analyzed the individual impact of bleeding events, hemoglobin (Hb) drop, and Red Blood Cells (RBC) transfusions on prognosis.. Methods and results: Consecutive patients (n=597) undergoing trans-femoral TAVI were prospectively enrolled. Peri-procedural Hb levels, RBC transfusions and major/life threatening bleeding events were documented and analyzed. To study the relationship between Hb drop, RBC transfusions and long-term mortality, the entire cohort was divided into 4 groups according to Hb drop (less or ≥ than 3 g/dl), and receiving RBC transfusion (yes /no). In the entire cohort mean Hb level decreased following TAVI (11.8±1.4 to 9.5 ±1.3 g/dl; p,0.001). Major/ life threatening bleedings occurred in 66 (10.1%) patients, and 179 (30%) patients received RBC transfusions. Major/life threatening bleedings were not independently ...
BACKGROUND: The purpose of the study was to investigate allogeneic blood transfusion (ABT) and preoperative anemia as risk factors for surgical site infection (SSI). STUDY DESIGN AND METHODS: A prospective, observational cohort of 5873 consecutive general surgical procedures at Basel University Hospital was analyzed to determine the relationship between perioperative ABT and preoperative anemia and the incidence of SSI. ABT was defined as transfusion of leukoreduced red blood cells during surgery and anemia as hemoglobin concentration of less than 120 g/L before surgery. Surgical wounds and resulting infections were assessed to Centers for Disease Control standards. RESULTS: The overall SSI rate was 4.8% (284 of 5873). In univariable logistic regression analyses, perioperative ABT (crude odds ratio [OR], 2.93; 95% confidence interval [CI], 2.1 to 4.0; p , 0.001) and preoperative anemia (crude OR, 1.32; 95% CI, 1.0 to 1.7; p = 0.037) were significantly associated with an increased odds of SSI. ...
We measured antibody (anti-HCV) to hepatitis C virus, which causes non-A, non-B hepatitis, by radioimmunoassay in prospectively followed transfusion recipients and their donors. Of 15 patients with chronic non-A, non-B hepatitis documented by liver biopsy, all seroconverted for the antibody; of 5 with acute resolving non-A, non-B hepatitis, 3 (60 percent) seroconverted. The development of anti-HCV was delayed (mean delay, 21.9 weeks after transfusion, or 15 weeks after the onset of clinical hepatitis) and took approximately one year in one patient. Antibody has persisted in 14 of the 15 patients with chronic disease (mean follow-up, greater than or equal to 6.9 years; maximum, greater than or equal to 12), but has disappeared in the 3 with acute resolving disease after a mean of 4.1 years. Anti-HCV was detected in samples of donor serum given to 14 (88 percent) of the 16 anti-HCV-positive patients for whom all donor samples were available. Only 33 percent of the anti-HCV-positive donors tested ...

Conclusions There is a lack of current guidelines outlining when to give terminally ill cancer patients a blood transfusion, due to the fact that every patient needs to be individually assessed. Generally, attitudes towards blood transfusions were positive; most thought that suffering was an appropriate reason for a blood transfusion. The large majority did not think that blood transfusions should be withheld. Attitudes towards blood transfusions with palliative intent were slightly more positive in oncology compared to palliative care healthcare professionals.. ...
BACKGROUND: Open simple prostatectomy has long been associated with large blood losses; hence allogeneic blood transfusion in this procedure is a standard practice world over. A review of literature suggests significant association between perioperative blood loss accompanying open simple prostatectomy and certain patient factors. The shortage of blood and blood products in our blood transfusion centres as well as the alarming risks of transfusion reactions and disease dissemination demanded a review of these factors with the aim of reducing morbidity associated with peri-operative blood loss and blood transfusion. OBJECTIVES: To assess blood loss, determine blood transfusion rate, and define some of the factors associated with peri-operative blood loss and blood transfusion in open simple prostatectomy. DESIGN : A prospective cohort study. SETTINGS: The urology units of Kenyatta National Hospital, Kenya. RESULTS: Ninety five patients who underwent open simple prostatectomy for benign prostatic ...
Some time ago my delightful 80+ year-old grandmother was diagnosed with a GI bleed that led to hospitalization and multiple transfusions. As I am the only nurse in the family, she made a point to tell me that she needed blood because her hemoglobins were low.. I quickly determined that she had no idea what hemoglobin was but she was confident her transfusion therapy was necessary because her trusted family physician had told her that her hemoglobins were low. During her admission, she signed without reading a general treatment consent that included a paragraph about blood transfusion. My grandmother was not told that there are risks associated with allogeneic transfusion nor was any alternative therapy offered. However, she believed that she was receiving appropriate medical care and she had no apparent adverse events with her hospitalization. Was my grandmother given adequate information to make an informed choice about her medical care? Did her physician and hospital meet minimum legal and ...

AU - Clifford, Leanne. AU - Kor, Daryl J. AU - Pathak, Jyotishman. PY - 2015/11/4. Y1 - 2015/11/4. N2 - Of the 21 million blood components transfused in the United States during 2011, approximately 1 in 414 resulted in complication [1]. Two complications in particular, transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO), are especially concerning. These two alone accounted for 62% of reported transfusion-related fatalities in 2013 [2]. We have previously developed a set of machine learning base models for predicting the likelihood of these adverse reactions, with a goal towards better informing the clinician prior to a transfusion decision. Here we describe recent work incorporating ensemble learning approaches to predicting TACO/TRALI. In particular we describe ...
Most physicians typically clamp and cut the umbilical cord immediately following delivery. Some physicians advocate for delaying the clamping of the babys umbilical cord, thereby increasing the flow of blood from the placenta to the child. The practice of delayed umbilical cord clamping has been shown to improve hematocrit levels, leading to an increased number of oxygen-carrying red blood cells throughout the body.. Hematocrit levels are an important factor during surgery and blood transfusions are often required to replace blood lost during complicated procedures. This is especially true in children with critical congenital heart disease.. Babies born with critical congenital heart disease often require multiple blood transfusions during corrective heart surgery due to the complexity of the surgery and the babies small size, said Carl Backes, Jr., MD, Neonatology fellow at Nationwide Childrens Hospital. However, data suggests that surgical outcomes are improved when fewer blood ...
Wheat grass juice reduces transfusion requirements in patients with thalassemia major: a pilot study.. Marwaha, R., Bansal, D., Kaur, S., Trehan A. 2004. Indian Ped. 41:716-720. Patients with thalassemia consuming wheat grass juice on a daily basis reduced on average their requirements for blood transfusion. Families raised and prepared the wheat grass at home and a comparison was made with the requirements of the patient in the preceding year. In nearly all patients the mean interval between visits increased and the blood transfused decreased during the wheat grass period. The mechanism involved is unknown.. ...
Published: 18 Jan 2017 , Last Updated: 18 Jan 2017 08:49:11 Karen Humm (Lecturer in Emergency and Critical Care) has been awarded a grant by Pet Plan for the following project: Is Cross Matching Beneficial Prior to the First Blood Transfusion in Cats? As veterinary practice has advanced, there has been a steady increase in the need for blood transfusions to help cats with a variety of diseases. However, identifying suitable blood donors and obtaining blood from healthy cats in a timely manner is extremely challenging. In situations when a cat has had a previous blood transfusion, it is recommended that prior to any subsequent transfusion a crossmatch screening test is performed. This is how we check that donor blood and patient blood are compatible. If no reaction is seen in this test, the donor is considered suitable and this should decrease the risk of the recipient having a reaction to the blood. A recent study of cats reported that administration of crossmatch compatible blood transfusions ...

BACKGROUND: In sub-Saharan Africa, the prevalence of malaria parasitemia in blood donors varies from 0.6% to 50%. Although the burden of TTM in malaria-endemic countries is unknown, it is recommended that all donated blood is screened for malaria parasites. This study aimed to establish the incidence of TTM and identify a suitable screening test. METHODS: Pregnant women, children, and immunocompromised malaria-negative transfusion recipients in a teaching hospital in Ghana were recruited over the course of 1 year. Parasites detected in recipients within 14 days of the transfusion were genotyped and compared to parasites in the transfused blood.

Per hospital policy, when a blood transfusion is ordered, two registered nurses are supposed to perform a two-tiered check to ensure the right blood is going to the right patient. Before the blood enters the room, two nurses must make sure the patients information lines up with the blood product. If everything matches, the nurses are supposed to then go to the patients bedside and perform additional checks to verify the identity of the patient.. However, some nurses have testified in the hearing that its common practice that everything is checked and signed off on at the nurses station and then the primary nurse goes into the patients room to verify identity and administer the blood transfusion.. During the hearing, nurses including and in addition to the two nurses fired, have said it is common practice to check the blood for the transfusion at the nurses desk. However, Karen Ames, director of quality and patient safety at Cayuga Medical Center, testified Monday that she found no evidence ...
Objective: To evaluate semen parameters and measure serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T) concentrations before and 7 days after packed red cell transfusion (PCTx) in adults with sickle cell disease (SCD). Methods: This prospective study investigated 18 young adults with transfusion-dependent SCD, aged 20.7 +/- 2.88 years, with full pubertal development (Tanner's stage 5) (euogonadal), and capacity to ejaculate. Their serum ferritin levels were 1488 +/- 557ng/ml. Basal serum concentrations of FSH, LH, T and IGF-I were evaluated before and 7 days after packed red cell transfusion (PCTx). We studied the effect of PCTx on semen parameters and the endocrine functions in these 18 patients with SCD. Results: Following PCTx, a significant increase of Hb from 8.5 +/- 1.17 g/dl to 10.5 +/- 0.4 g/dl was associated with increased testosterone (12.3 +/- 1.24 nmol/L to 14.23 +/- 1.22nmol/L and gonadotropin concentrations.

Abstract:. BACKGROUND AND OBJECTIVE: This audit was conducted as a part of a quality assurance activity to assess the frequency of receiving completely filled out blood transfusion reaction forms which were accompanied by the required samples. Once this information is known, we will elevate the bar each year to achieve 100% compliance. The sub-aim was to evaluate the frequency of the reported transfusion reactions.. MATERIALS AND METHODS: The study was conducted from 1st April 2010 to 30th April 2011. The information was evaluated and the frequency of receiving completely filled blood transfusion reaction forms was assessed. The variables identified were the type of transfusion reaction, the blood component transfused, the health care personnel filling the form, and whether there was legible handwriting and a completely filled form. Transfusion reactions were reported as a percentage of the total number of units transfused.. RESULTS: During the study period, 17,880 packed red cells, 13,200 ...
This program will review the creation and benefits of Blood School, an eight-hour introductory course on transfusion safety for nurses. Recognizing that primary blood transfusion education was too procedure-centric, this course was developed as a supplement to provide education on the core foundations of transfusion medicine. Blood School uses a combination of didactic and active learning approaches, in order for the participants to feel more knowledgeable, comfortable, and safer with all transfusion-related processes. In doing so, it empowers them to be better advocates for patients, take action whenever they recognize negative situations related to blood transfusions, and help ensure that the right patient gets the right blood component for the right reason in the safest way. ...

There have been previous studies with similar hypotheses and methodology. Engoren et al. 12 studied 1,915 subjects undergoing first-time isolated coronary artery bypass at St. Vincent Mercy Medical Center, Toledo, Ohio. In a Cox regression model, they demonstrated that age, New York Heart Association functional class IV, chronic obstructive pulmonary disease, peripheral vascular disease, and perioperative blood transfusion were predictors of mortality occurring between 1 and 5 yr after surgery. Detailed information about the number of units transfused was not available; therefore, quantification of transfusion was done in a limited manner, subjects were grouped according to transfusions given during the intraoperative period, postoperative period, or both. Koch et al. 13 studied 10,289 subjects undergoing isolated coronary artery surgery at the Cleveland Clinic, follow-up was 10 yr, and transfusion was quantified by the number of units of red cells transfused to subjects in the perioperative ...

Substantial variability in practice exists in clinical transfusion, patient blood management and blood conservation in paediatrics. Neonates and children are frequently transfused patient populations, yet they are relatively under-represented in clinical trials and the evidence-base to guide practice is limited. A number of clinical practices are extrapolated from the results of adult studies. Yet neonates and children have unique pathophysiology, specific vulnerabilities and different risk profiles compared to adult transfusion recipients. A disproportionate number of transfusion adverse events are reported in the neonatal and paediatric age groups. Any adverse outcome related to transfusion is particularly important in these young recipients, as most are anticipated to live for many years post transfusion. Transfusion decision making in paediatrics needs to consider the potential risks and benefits of a transfusion and any alternatives to transfusion. ...

I have anemia and needed a blood transfusion and attempted my first transfusion last week. After about a tablespoon of blood went into my IV, my vision grayed out and I dont remember what happened next. I was told I had chills, diaphoresis, decreased level of consciousness, eyes rolling back in head and woke up so to speak, vomiting. What happened to me? They said I had no fever but had a severe transfusion reaction. I received Benadryl and Solu-Medrol and a bag of fluid after that. They had stopped the blood when I came to and said my blood pressure had dropped to 70/40 and my pulse had dropped. My family doctor was called and diagnosed it as a vasovagal reaction. Can a severe blood transfusion reaction be called a vasovagal reaction? They said there was no hemolyzation of the blood. What exactly happened? How often does this happen? They gave me another unit with the premedication and filter, and it seemed to work okay that time. What do I need to understand about what happened ...
In one of the largest randomized controlled trials (RCTs) on GDT, the incidence of blood transfusions was double (22 vs 11%) in the GDT group patients, who received nearly twice the amount of colloids compared to the control group, even though the same transfusion threshold (Hb , 8 g/dl) was used for both groups [11]. The most feasible explanation for this clinically relevant and statistically significant difference (p = 0.04 based on a chi square test), which was not calculated nor discussed in the article [11], is that more patients in the GDT group reached Hb levels below the transfusion threshold due to hemodilution, prompting physicians to order blood transfusions. Other RCTs have also reported that patients in the GDT group, who received significantly more colloid boluses, received significantly more blood transfusions [12, 13] and had significantly higher blood loss [13] compared to the standard therapy group. In another study, the administration of more colloids led to lower Hb and DO2 ...

Transfusion-Related Acute Lung Injury (TRALI) is an important life-threatening complication that is related with blood transfusion. The frequency is reported as 1/5.000. It is generally characterized with hypoxia that appears at the 2-6th hours after the blood transfusion, bilateral infiltration in the chest radiography, and non-cardiogenic pulmonary edema. Acute respiratory distress, hypotension, tachycardia and fever accompany the clinical picture. Past surgery, blood transfusion, and sepsis are among the factors that trigger the disease. In this study, the efficiency of the hemodialysis applied in the right time in the treatment of a heavy TRALI case developed after a blood transfusion has been presented..

Abstract:. BACKGROUND: Intraosseous (IO) vascular access is increasingly used as an emergency tool for achieving access to the systemic circulation in critically ill patients. The role of IO transfusion of blood in Damage Control Resuscitation is however questionable due to possible inadequate flow rate and hemolysis. Some experts claim that IO transfusion is contraindicated. In this study we have challenged this statement by looking at flow rates of autologous fresh whole blood reinfusion and hemolysis using two of the commonly used FDA-approved and CE-marked sternal needles. Additionally, the success rate of sternal access between the two devices is evaluated.. METHODS: Volunteer professional military personnel, were enrolled prospectively in an non-randomized observational study design. We collected 450 ml of autologous whole blood from each participant. Participants were divided into the following three groups of 10: T.A.L.O.N. IO, FAST1 IO, and intravenous (IV) group. The reinfusion was ...

A panel of eight different primary antibodies and two different phycoerythrin-conjugated secondary antibodies was used for the detection of different blood populations. The flow cytometer used in this study was the BD FACSArray® instrument. Mixed red blood cell populations were prepared from phenotype known donors. Linearity, specificity, recovery, precision, robustness and interday-precision were tested for every primary antibody used in the presented assay. The technique of signal amplification was utilized for an improved separation of antigens with weak or heterozygous expression to improve the interpretation of histograms. The resulting method allowed to clearly ...
A delayed hemolytic transfusion reaction (DHTR) is a type of transfusion reaction. It is defined as fever and other symptoms/ signs of hemolysis more than 24 hours after transfusion; confirmed by one or more of the following: a fall in haemoglobin (Hb) level or failure of Hb level to rise after transfusion rise in bilirubin (jaundice) incompatible crossmatch not detectable pre-transfusion. This can occur up to four weeks after the transfusion. Delayed blood transfusion reaction occurs more frequently (1 in 20,569 blood components transfused in the USA in 2011) when compared to acute haemolytic transfusion reaction. One way this can occur is if a person without a Kidd blood antigen receives a Kidd antigen in a transfusion. Other common blood groups with this reaction are Duffy and Kell.

Many people diagnosed with haematological malignancies experience anaemia, and red blood cell (RBC) transfusion plays an essential supportive role in their management. Different strategies have been developed for RBC transfusions. A restrictive transfusion strategy seeks to maintain a lower haemoglobin level (usually between 70 g/L to 90 g/L) with a trigger for transfusion when the haemoglobin drops below 70 g/L), whereas a liberal transfusion strategy aims to maintain a higher haemoglobin (usually between 100 g/L to 120 g/L, with a threshold for transfusion when haemoglobin drops below 100 g/L). In people undergoing surgery or who have been admitted to intensive care a restrictive transfusion strategy has been shown to be safe and in some cases safer than a liberal transfusion strategy. However, it is not known whether it is safe in people with haematological malignancies.To determine the efficacy and safety of restrictive versus liberal RBC transfusion strategies for people diagnosed with

Children undergoing cardiac surgery with cardiopulmonary bypass (CPB) are at high risk of being exposed to relatively large volumes of allogeneic blood products. If blood transfusion can be life-saving in some circumstances (e.g. major haemodilution or massive haemorrhage), the administration of large volumes of allogeneic blood products has been shown to significantly increase the risk of postoperative complications. Over the last decades, different strategies have been developed to reduce the need for blood product transfusions.. Acute normovolemic hemodilution (ANH) has been used for a long time in adults undergoing high bleeding risk procedures, including cardiac surgery. While some studies reported a decrease in the incidence of transfusion and in the volume of red blood cells transfused, only limited evidence exists in infants and children undergoing cardiac surgery. Major differences exist between children and adults undergoing cardiac surgery, limiting the use of ANH to a small number of ...
There are two common forms of treatment:. Steroid therapy: Approximately 70% of people diagnosed with DBA have steroid therapy which improves their anaemia. However, in some cases steroid therapy can stop working and the anaemia may return. Sometimes steroid therapy is used in combination with cyclosporin A. Those who respond to steroid treatment may remain on steroids for the rest of their lives.. Blood transfusions: For those who do not respond to steroid treatment, regular blood transfusions may be required. It is important to note that recipients of regular blood transfusions may be at risk of iron overload*. Iron overload occurs when there is a buildup of iron in the body as a result of blood transfusions. It is important to discuss this with your health care professional.. ...

Despite having many studies to evaluate the role of TXA in surgeries, limited literature is available on its role in hip fracture surgeries. In an RCT, TXA was administered as an initial bolus dose of 500mg before surgery followed by continuous infusion at 1mg/kg/h for the duration of surgery. Results showed that the differences in mean reduction in Hb and mean volume of blood loss postoperatively between TXA and placebo groups were significant. In addition, only 7 out of 45 patients in TXA group required blood transfusion compared to 18 out of 45 in placebo group and the difference was again significant.5 On the contrary, another RCT in 2010 concluded that there was no significant difference in blood transfusion rates between TXA and placebo groups after surgery for hip fracture.3 Therefore, although effectiveness of TXA in reducing post-surgical blood loss and transfusion requirements have been shown by multiple studies, but its effectiveness, specifically in hip fracture surgeries, is yet to ...

Transfusion threshold adherence will be described as the proportion of per protocol RBC transfusion events. A transfusion threshold event is defined as an occurrence which starts when a haemoglobin value is measured at or below the allocated threshold for the first time since the previous event and ends when one of the following occurs: (1) an RBC transfusion is administered; or (2) a repeat haemoglobin is obtained above the allocated threshold within 24 hours of the original measure.. Transfusion threshold non-adherence will be considered to have occurred with any of the following: (1) an RBC transfusion occurs before a transfusion threshold is crossed; or (2) in the liberal arm, a transfusion is not given following a threshold crossing. Transfusion threshold non-adherence will be considered a deviation if: (1) the early transfusion occurs within 5 g/L above the allocated threshold (eg, ≤105 g/L for the liberal arm or ≤85 g/L for the restrictive arm) or, (2) in the liberal arm, an RBC ...
Indications for red blood transfusion depend on clinical assessment and the cause of the anemia. In a stable, non-bleeding patient, often a single unit of blood is adequate to relieve patient symptoms or to raise the hemoglobin to an acceptable level. Transfusions are associated with increased morbidity and mortality in high-risk hospitalized inpatients. Transfusion decisions should be influenced by symptoms and hemoglobin concentration. Single unit red cell transfusions should be the standard for non-bleeding, hospitalized patients. Additional units should only be prescribed after re-assessment of the patient and their hemoglobin value.. Sources:. Bracey AW, et al.

Preoperative autologous donation is the process of collecting and storing a patients own blood prior to an elective procedure where it is anticipated that the patient will most likely require a blood transfusion. A patients suitability for preoperative autologous donation is based on their ability to tolerate several venesections (blood donations) taken over a short period of time, their age, adequate venous access (to enable blood to be taken) and reliable dates for elective surgery.. Preoperative autologous donation can deplete the bodys iron stores and iron is very important to ensure your blood can carry enough oxygen. Even though it is your blood, risks still exist with autologous blood, including bacterial contamination, clerical error and the increased chance of receiving a blood transfusion. Whilst it is commonly perceived that autologous transfusion removes the risk of transfusion-transmissible infection, the overall safety of autologous blood transfusion is not significantly ...
Why this is important:- Audits have shown that fresh frozen plasma is widely used for non-bleeding patients in the intensive care unit (ICU) and many other clinical settings. There is a large variation in dose and no real evidence base to guide practice.

PURPOSE: This study tested the hypothesis that autologous blood transfusion (ABT) of ~50% of the red blood cells (RBC) from a standard 450-mL phlebotomy would increase mean power in a cycling time trial. In addition, the study investigated whether further ABT of RBC obtained from another 450-mL phlebotomy would increase repeated cycling sprint ability.. METHODS: In a randomized, double-blind, placebo-controlled crossover design (3-month wash-out), nine highly trained male subjects donated two 450-mL blood bags each (BT trial) or were sham phlebotomized (PLA trial). Four weeks later, a 650-kcal time trial (n = 7) was performed 3 d before and 2 h after receiving either ~50% (135 mL) of the RBC or a sham transfusion. On the following day, transfusion of RBC (235 mL) from the second donation or sham transfusion was completed. A 4 × 30-s all-out cycling sprint interspersed by 4 min of recovery was performed 6 d before and 3 d after the second ABT (n = 9).. RESULTS: The mean power was increased in ...
Acute reduction in hemoglobin levels is frequently seen during sepsis. Previous studies have focused on the management of anemia in patients with septic shock admitted to intensive care units (ICUs), including aggressive blood transfusion aiming to enhance tissue oxygenation. To study the changes in hemoglobin concentrations during the first week of sepsis in the setting of Internal Medicine (IM) units, and their correlation to survival. Observational prospective study. We recorded hemoglobin values upon admission and throughout the first week of hospital stay in a consecutive cohort of septic patients admitted to IM units at a community hospital, the patients were enrolled into a prospective registry. Data on blood transfusions was also collected, we examined the correlation between hemoglobin concentrations during the first week of sepsis and survival, the effect of blood transfusion was also assessed. Eight hundred and fifteen patients (815) with sepsis were enrolled between February 2008 to January

Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-associated mortality in the US. Previously, we established an immune-mediated TRALI mouse model, wherein mice with cognate antigen were challenged with MHC class I mAb. In this study, when mice housed in a rodent, specific pathogen-free barrier room were challenged with MHC I mAb, there was significant protection from TRALI compared with nonbarrier mice. Priming mice with LPS restored lung injury with mAb challenge. Using TLR4-deficient bone marrow chimeras, the priming phenotype was restricted to animals with WT hematopoietic cells, and depletion of either neutrophils or platelets was protective. Both neutrophils and platelets were sequestered in the lungs of mice with TRALI, and retention of platelets was neutrophil dependent. Interestingly, treatment with aspirin prevented lung injury and mortality, but blocking the P selectin or CD11b/CD18 pathways did not. These data suggest a 2-step mechanism of TRALI: ...
Introduction:. HLA specific antibodies detection (HSA) and that of Donor Specific Antibodies (DSA) were revolutionized by the introduction of solid phase assays (Luminex®), therefore making these antibodies a powerful biomarker for humoral injuries to the allograft. Determinants of HSA development entail non-adherence to immunosuppressive drugs but also allosensitizing events such as red blood cell (RBC) transfusions. Recent works showed a higher incidence of DSA in transplanted patients following RBC transfusion events, but no specific data exist for AntiThymocyte Globulin (ATG) induction.. This work aims at assessing whether peri-transplant RBC transfusion resulted in post-transplant HLA sensitization, in the setting of ATG induction therapy.. Patients and methods:. All consecutive patients benefiting from a first ATG-induced kidney allograft between 2004 and 2014 at our center with no history of HLA immunization were included retrospectively, provided transfusion history and HSA history were ...

Negative side effects of blood transfusion therapy are uncommon. Blood banks, hospitals, and health-care providers take many precautions to minimize risks before each blood transfusion. Blood banks test each unit of blood to find out its ABO type and Rh status.

It begins with the basics of genetics and immunology, and then progresses to the technical aspects of blood banking and transfusion. Chapters are divided into sections on: Basic Science Review; Blood Group Serology; Donation, Preparation, and Storage; Pretransfusion Testing; Transfusion Therapy; Clinical Considerations; and Safety, Quality Assurance, and Data Management. Developed specifically for medical technologists, blood bank specialists, and residents, the new edition conforms to the most current standards of the American Association of Blood Banks (AABB).
Transfusion-associated graft-versus-host disease (TA-GvHD) is a rare complication of blood transfusion, in which the donor T lymphocytes mount an immune response against the recipients lymphoid tissue. Donor lymphocytes are usually identified as foreign and destroyed by the recipients immune system. However, in situations where the recipient is immunocompromised (inborn immunodeficiency, acquired immunodeficiency, malignancy), or when the donor is homozygous and the recipient is heterozygous for an HLA haplotype (as can occur in directed donations from first-degree relatives), the recipients immune system is not able to destroy the donor lymphocytes. This can result in graft-versus-host disease. The incidence of TA-GvHD in immunocompromised patients receiving blood transfusions is estimated to be 0.1 - 1.0%, and mortality around 80 - 90%. Mortality is higher in TA-GvHD than in GvHD associated with bone marrow transplantation, where the engrafted lymphoid cells in the bone marrow are of donor ...
In the past few years there has been increasing concern about blood transfusion safety. Avoidable transfusion errors, mostly in patient identification, remain a serious cause of injury and death. There is also heightened awareness of the risk of transmission of viral and bacterial infections. Of particular concern in Britain is the (theoretical) possibility of transmission of variant Creutzfeldt-Jakob disease.. This review puts these risks in perspective (table) and describes the new measures that have been introduced to improve blood safety. It also describes changes in attitude and practice that will affect users of blood in all disciplines, including general practitioners advising patients of the pros and cons of transfusion. Finally it emphasises the need for careful education and training of all those involved in blood prescribing and blood component administration. ...

FISH is a very general technique. The differences between the various FISH techniques are usually due to variations in the sequence and labeling of the probes; and how they are used in combination. Probes are divided into two generic categories: cellular and acellular. In fluorescent "in situ" hybridization refers to the cellular placement of the probe Probe size is important because longer probes hybridize less specifically than shorter probes, so that short strands of DNA or RNA (often 10-25 nucleotides) which are complementary to a given target sequence are often used to locate a target. The overlap defines the resolution of detectable features. For example, if the goal of an experiment is to detect the breakpoint of a translocation, then the overlap of the probes - the degree to which one DNA sequence is contained in the adjacent probes - defines the minimum window in which the breakpoint may be detected. The mixture of probe sequences determines the type of feature the probe can detect. ...

The extent of the surgical site extends one to two centimeters beyond the boundaries of malignancy. Superficial lymph nodes may also need to be removed. If the malignancy is present in muscular tissue in the region, it is also removed. In some cases, the surgeon is able to preserve the clitoris though the malignancy may be extensive. The cancerous tissue is removed and the incision is closed.[3] Post operative care may ...

  • Effects of universal vs bedside leukoreductions on the alloimmunization to platelets and the platelet transfusion refractoriness. (
  • Typically, fresh frozen plasma will contain the largest amount of the antibodies, followed by platelets and then red cells because all three blood components contain plasma, which can contain antibodies. (
  • Nowadays, blood is mainly processed in its different components that are red blood cells, platelets, plasma and some therapeutics. (
  • The transfusion is done with one or more of the following parts of blood: red blood cells, platelets, plasma, or cryoprecipitate. (

(
  • The study did have several limitations, the researchers noted, including the fact that they did not assess the independent effects of platelets because they were co-administered with red blood cells. (
  • White blood cells help defend the body against infection by producing antibodies, which help destroy foreign germs in the body. (
  • Directed donor blood allows the patient to receive blood from known donors. (

  • Most people infected with the Zika virus don't show any symptoms, blood donors may not know they have been infected. (
  • Blood donor screening on the basis of a questionnaire, without a laboratory test, is insufficient for identifying Zika-infected blood donors in areas with active mosquito-borne transmission of Zika virus due to the high rate of asymptomatic infection. (
  • In most cases, the blood comes from volunteer donors. (
  • Since there's no medical evidence that blood from directed donors is any safer than blood from volunteer donors, most patients receive blood donated through blood drives, which are often run by independent collection agencies like the American Red Cross. (
  • Blood banks screen donors and test donated blood to reduce the risk of transfusion-related infections, so infections, such as HIV or hepatitis B or C, are extremely rare. (
  • Some basic criteria are used to ensure that blood donation is safe for recipients and donors. (
  • Donation centers try to ensure that donors who recently had West Nile virus do not give blood for 120 days. (
  • This risk may be higher during the summer when West Nile virus is most likely to infect blood donors. (

  • Transfusion medicine is in perpetual evolution and has faced several challenges from donors screening to clinical practices through blood preparation. (
  • Research in transfusion medicine is diverse, interdisciplinary and regularly proposes innovation from the donors to the patients along the whole transfusion chain. (

  • Preliminary evidence from several small studies, including a pilot study overseen by Carson, have shown that patients who have had a heart attack and have anemia, which restricts the body's ability to carry oxygen, may have an increased risk of mortality with a restrictive transfusion approach. (
  • When the amount or quality of our red blood cells is too low, the condition is known as anemia. (
  • If the anemia is serious, the baby may require a blood transfusion while they are still in the uterus. (
  • The goal of this treatment is to prevent complications of anemia and provide the baby with an adequate supply of red blood cells to keep them healthy until delivery. (
  • Depending on the severity of the anemia, additional fetal transfusions may be needed until the baby's birth. (
  • He suspected that the baby's fluid buildup was caused by anemia, a shortage of red blood cells. (

  • If the test indicated anemia, the baby would need a blood transfusion in order to survive. (
  • Fetal blood sampling (FBS) shows that the fetus has severe anemia. (
  • Red blood cells, the most commonly transfused part, are used to increase the blood's ability to carry oxygen and prevent tiredness and other complications. (
  • Blood transfusions usually occur without complications. (
  • Blood transfusions are generally considered safe, but there is some risk of complications. (
  • Mild complications and rarely severe ones can occur during the transfusion or several days or more after. (
  • This will help to reduce the risk of complications resulting from blood incompatibility. (
  • If your body does not have enough of one of the components of blood, you may develop serious life-threatening complications. (
  • It is very important, in order to avoid any complications during a blood transfusion, to detect individuals with rare blood types. (

  • Explain to interested patients that women undergoing heart surgery may be more likely to experience complications largely due to the fact that they are more likely to receive transfusions of donor blood. (
  • To reduce complications related to blood transfusions, the study authors called for increased use of leukoreduction to diminish the chances of an inflammatory response or infection. (
  • Intrauterine transfusions rarely have complications. (
  • This is usually done as a lifesaving maneuver to replace blood cells or blood products lost through severe bleeding, during surgery when blood loss occurs or to increase the blood count in an anemic patient. (

  • Allaire has performed many fetal blood transfusions during his career, but the procedure never had been done before at Northeast Georgia Medical Center. (
  • Using another's blood must first start with donation of blood. (
  • In developed countries, donations are usually anonymous to the recipient, but products in a blood bank are always individually traceable through the whole cycle of donation, testing, separation into components, storage, and administration to the recipient. (
  • In developing countries the donor is sometimes specifically recruited by or for the recipient, typically a family member, and the donation occurs immediately before the transfusion. (
  • Since the inception of the Blood and Transfusion Safety project based on voluntary non-remunerated blood donation in July 2014, the Blood Transfusion Services have been using the WHO's generic guidelines. (
  • Promoting voluntary non-remunerated blood donation, and safe provision of blood and blood products is vital for the treatment of many life threatening situations that require blood transfusion. (
  • When someone donates their blood for their own use, it is called autologous blood donation or autotransfusion. (
  • However, some blood banks that operate blood donation campaigns whether in a Muslim society or not (as in the Western world) often don't provide any information about who is receiving the donated blood other than. (

  • Patients who received allogeneic blood were 4.4 times more likely to develop an infection following cardiac surgery than those who didn't, and women were 44.6 times more likely to be transfused than men, reported Mary A.M. Rogers, Ph.D., M.S., of the University of Michigan in Ann Arbor, and colleagues in the December issue of the Journal of Women's Health . (
  • Cardiac surgery accounts for about 20% of all allogeneic blood transfusions in the U.S, according to information cited in the new study. (
  • Patients who received allogeneic blood were 4.4 times more likely to develop an infection than those patients who did not undergo transfusion (95% CI: 1.5 to 13.2, P =0.009) with adjustment for demographic and clinical factors. (
  • The link between infection and allogeneic transfusions is still a subject of debate in the medical community, but donor blood may increase humoral immunity and decrease cell-mediated immunity, the researchers said. (
  • FDA has licensed two blood donor screening tests to detect Zika virus RNA in human plasma: the cobas Zika Test performed on the cobas 6800/8800 (Roche Molecular Systems, Inc) on October 5, 2017 and the Procleix Zika Virus Assay (Grifols Diagnostic Solutions, Inc.) on July 5, 2018. (

  • Jehovah's Witnesses believe that the Bible prohibits ingesting blood and that Christians should not accept blood transfusions or donate or store their own blood for transfusion. (
  • Certain medical procedures involving blood are specifically prohibited by Jehovah's Witnesses' blood doctrine. (
  • So says the Bible's book of Leviticus, and it is for this reason that Jehovah's Witnesses shun blood transfusions. (
  • As long as surgeons use special techniques, Jehovah's Witnesses can have surgery - including operations with the greatest potential for blood loss, such as open-heart surgery - without ever receiving a drop of someone else's blood. (
  • Their cases come after a Jehovah's Witnesses couple in Durban were challenged in the Durban High Court by the KwaZulu-Natal Health MEC Sibongiseni Dhlomo and a doctor, after they refused to allow their chronically ill five-year-old son to have a blood transfusion in September. (
  • It really doesn't matter one whit if the reason for refusing life-saving treatment, be it transfusion, chemotherapy, or whatever, is a careful consideration of the risk/benefit ratio, a desire to pursue quackery instead of evidence-based medicine, or religious delusions based on a tortured interpretation of ancient scripture developed a mere 62 years ago, such as the teachings of the Jehovah's Witnesses about blood transfusion--or whatever. (
  • For example, the Jehovah's Witnesses organization prohibits the use of blood transfusions . (
  • Individual Jehovah's Witnesses are expected to die or let their children die, rather than break this command, even though the Scriptures nowhere teach that blood transfusions are wrong. (

  • A blood transfusion is a fairly simple medical procedure. (
  • If your child needs a blood transfusion, the doctor will speak with you about the procedure. (
  • A blood transfusion is a routine medical procedure in which donated blood is provided to you through a narrow tube placed within a vein in your arm. (
  • This potentially life-saving procedure can help replace blood lost due to surgery or injury. (
  • The procedure typically takes one to four hours, depending on which parts of the blood you receive and how much blood you need. (
  • A nurse will monitor you throughout the procedure and take measures of your blood pressure, temperature and heart rate. (
  • People with cancer may donate their own blood in case they need a blood transfusion during or after surgery or an invasive procedure. (
  • Certain medical procedures involving blood fractions or that use a patient's own blood during the course of a medical procedure, such as hemodilution or cell salvage, are a matter of personal choice, according to what a person's conscience permits. (
  • This is when someone donates their own blood ahead of time for a planned surgery or other procedure. (
  • Blood transfusions are a common procedure but like any medical procedure, there are risks. (
  • A blood transfusion is a common procedure where donated blood or blood components from a volunteer donor are given through an intravenous line (IV) to a patient to replace blood and blood components that may be too low. (
  • A blood transfusion is a medical procedure in which compatible, cross-matched blood (red blood cells) is transfused into a person through an intravenous line (IV). (
  • There are other ways to reduce the risk of getting blood clots after a surgical procedure, and it is important doctors continue to take these measures," he said. (
  • It means a procedure used to transfer blood (or some products based on blood) from the circulatory system of one human to that of another human. (

  • NHSBT's role is to supply blood components, diagnostic services and stem cell services safely and reliably to hospitals in England and North Wales, as well as tissues and solid organs to hospitals across all the UK. (
  • Donations might be of whole blood, or the components can be separated with the help of fractionation.The collection process is mainly done by the blood banks. (
  • A blood transfusion usually isn't whole blood - it could be any one of the blood's components. (
  • 6 Pathogen Inactivation (of Blood Components) ( Chris Prowse ). (
  • Most blood that passes the tests is then split into its components and sent out for use. (
  • Blood and its components can be stored or used for only a short time before they must be thrown away. (
  • Transfusions are used to treat blood loss or to supply blood components that your body cannot make for itself. (
  • In addition to these causes, the cat's immune system may react to various components in the donor's blood. (
  • Our offered blood transfusion set is designed and developed by using highly medicated PVC also using highly advance technology and components. (
  • To address the biological relevance of this approach, we compared the efficiency of TSE transmission by blood and blood components when administrated either through transfusion in sheep or by intra-cerebral inoculation (IC) in transgenic mice (tg338) over-expressing ovine PrP. (
  • Most of the time a transfusion is not a 'whole blood' transfusion, but rather certain blood products, with red blood cells being the most common. (
  • Red blood cells carry oxygen to the body's tissues and remove carbon dioxide. (
  • There are four major blood types, each with a different chemical marker that's attached to a person's red blood cells. (
  • A transfusion provides the part or parts of blood you need, with red blood cells being the most commonly transfused. (
  • The attacked cells release a substance into your blood that harms your kidneys. (
  • Plasma is the liquid part of blood that carries the blood cells. (
  • A transfusion gives you healthy red blood cells from a donor to make up for the ones you don't have. (
  • Blood types get their names based on which proteins are on the surface of the blood cells. (
  • This happens when your body reacts to white blood cells in the donated blood. (
  • If you've had a febrile reaction in the past, your doctor can give you blood without the white blood cells next time. (
  • The blood is usually processed and the blood plasma (where blood cells are suspended) is separated from the blood by centrifugation. (
  • As I mentioned above, Procrit stimulates the production of new red blood cells. (
  • In most of the cases, the patient doesn't require 'whole blood transfusion' but needs specific blood products, such as red blood cells. (
  • They involve scientists and physicians in hematology and related pathology, basic sciences, material science, immunology, cell biology, hematopoietic stem cells and in vitro production of blood products as well as logistics, hemovigilance and regulation. (
  • Blood transfusions help rapidly reinfuse red blood cells. (
  • When a patient receives the wrong blood type, the body begins to attack the blood cells as a foreign substance, causing the newly transfused cells to burst. (
  • He is well-known as the architect of the blood transfusion system in the country and has spent his entire life doing groundbreaking research on blood cells. (
  • He has also conducted and published several research articles that include discovering blood grouping antisera and enzymes Bromoline from Bangladeshi pineapples for detection of irregular antibodies from mangoes and jackfruits for detection of A1 red cells. (
  • The structure of the HBOC-201 is smaller and more mobile than blood cells, therefore allowing the HBOC-201 molecules to effectively distribute oxygen throughout the body. (
  • It can also fill an unmet medical need when compatible red blood cells are not readily available or when there is a need or preference to avoid blood transfusions. (
  • In this case it is red blood cells that are given to a fetus. (
  • Rh incompatibility -the mother develops antibodies to fetal blood cells. (
  • They cause destruction of blood cells in the fetus. (
  • Blood is made up of many tiny cells that all play a different role in the body. (
  • Red Blood Cells (RBC) - RBCs carry oxygen from the lungs to all the parts of the body. (
  • Too few red blood cells results in not enough oxygen circulating through the body. (
  • Plasma - This is the liquid that blood cells are suspended in. (
  • it describes whether or not you carry a protein on your blood cells. (
  • Blood is a mixture of cells and liquid. (
  • Red blood cells make up about 40%-45% of a person's blood and live for 120 days. (
  • White blood cells make up less than 1% of a person's blood. (
  • A person's blood has about 1 platelet for every 20 red blood cells. (
  • Blood transfusions contain a specific blood cell type that is given to a person to replace cells that have been lost or are not being adequately produced. (
  • Moreover, the investigators suspect that these altered red blood cells, in combination with inflammation, may further raise the risk for clots. (
  • A reaction causes your body to form antibodies that attack the new blood cells. (
  • Blood loss can also reduce the number of oxygen-carrying red blood cells in the blood, which may prevent enough oxygen from reaching the rest of the body. (
  • If you have lost too many red blood cells or are not making enough of them, you are given packed red blood cells. (
  • or transfusion of damaged red blood cells which have been improperly stored (i.e., due to excessive heating or freezing). (
  • Our red blood cells carry oxygen and nutrients to the rest of our bodies, and are vitally important to our health. (
  • Red blood cells from a donor whose blood type is compatible with the baby's are passed through the needle into either the umbilical cord vein or the fetus' abdomen. (
  • Spinning the blood in a centrifuge causes red cells to settle to the bottom, where they can be separated from the plasma. (
  • Published evidence in a limited number of cases (62 cats) indicates that cats do not appear to have naturally-occurring antibodies against canine red blood cell antigens: compatibility tests prior to the first transfusion did not demonstrate any evidence of agglutination or haemolysis of canine red cells in feline serum or plasma. (
  • However, antibodies against canine red blood cells are produced rapidly and can be detected within 4-7 days of the transfusion, leading to the destruction of the transfused canine red cells in a delayed haemolytic reaction. (
  • A blood transfusion is given to replace fetal red blood cells that are being destroyed by the Rh-sensitized mother's immune system. (
  • Several conditions and diseases may mean a person can't donate blood, including a diagnosis or history of certain cancers. (
  • A fresh frozen plasma transfusion can be given to people who have bleeding disorders, certain types of cancer or liver diseases. (
  • This protein aberration can be passed from humans to healthy laboratory animals through the injection of diseased brain tissue from human sufferers, prompting fears that the diseases could also be passed from human to human through blood transfusion. (
  • Blood that carries diseases and illnesses is not used. (
  • Blood transfusions can also be applied as a treatment to certain diseases of the blood (like Anaemia , for example). (
  • Donated blood is then carefully tested for certain diseases and to find out the blood type. (
  • A few weeks after receiving transfusions, when he had a serious allergic reaction within 10 minutes of eating salmon and another after he ate a chocolate peanut butter cup, his doctors soon identified the source of the problem. (
  • Even when blood is a perfect match, a patient may suffer from an allergic reaction if blood triggers the body's immune response. (
  • You may have a mild allergic reaction even if you get the correct blood type. (
  • Transfusion of whole blood and RBCs increased by 7.6 percent to 12,389,000 units. (
