Introduction: The estimation of blood loss rate during surgery for prediction of transfusion of blood or blood products requirement is important for surgeon and anesthesiologist. In regard to various results and lack of definite index for start of transfusion in operating rooms, the assessment of blood loss reduction is necessary. The aim of study was evaluation of hemoglobin (Hb) value and hemorrhage estimation rate. Methods and materials: 48 cases underwent major orthopedic surgery with high probability of intraoperative blood loss rate was included in study. Hb, hematocrit (Hct) and basic vital signs were measured preoperatively and blood loss rate was estimated by using of blood volume in suction, bloody gases and blood loss in operation field and recorded. The blood sample per 100 mL blood loss was sent to laboratory. For transfusion deciding based on Hb, we did not any intervention. Results: 26 males and 22 females were included in study. Our results showed that Hb value of males was higher
Background Ahead of routine screening process of blood items many sufferers with haemophilia were infected with hepatitis C computer virus (HCV) Zaurategrast and have subsequently gone on to develop end-stage liver disease (ESLD). and 4 (22%) experienced hepatocellular carcinoma. Median intra-operative blood loss was 4.2 l (range 0.8-12) and all received coagulation factor support peri-operatively. Coagulation was unsupported by 72 h post-operatively in all recipients. Two sufferers developed problems as a complete consequence of post-operative bleeding. At a median follow-up of 90 a few months 8 sufferers have passed away including 4 from the 5 sufferers which were HIV positive. The median success of sufferers with and without HIV co-infection was 26 and 118 a few months respectively. Bottom line LT in sufferers with haemophilia treatments the coagulation disorder and in the Zaurategrast lack of HIV/HCV co-infection is certainly connected with long-term individual success. = 5) ahead of 1997 or ...

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 ...
BACKGROUND:Visual estimation and gravimetric methods are commonly used to quantify the volume of blood loss during cesarean delivery (CD). However, the correlation between blood loss and post-CD hemoglobin (Hb) is poorly studied, and it is unclear whether the correlation varies according to how bloo
Considering the potential impact on patients and decision making, these findings may be important to ED care. The types of situations assessed in the study were found to lead to both low precision and poor accuracy in estimating blood loss. Emergency physicians should be aware of the potential for inaccuracies in making and using these estimates in clinical care.. Future research should explore various interventions that may improve the ability to estimate blood loss during clinical decision making. More information on the value of adding these estimation skills to emergency medicine training is also warranted. Training programs to enhance the estimation skills of physicians should be tested, evaluated, and, if successful, incorporated into emergency medicine and advanced trauma care. Many factors can lead to poor estimation of blood loss, especially during early evaluations. The key is to interpret blood loss estimates with great caution. ...

While the occurrence of blood loss per rectum in general practice is common and usually not serious, it may be the first symptom of a colorectal malignant disorder. To determine the occurrence and clinical significance of overt blood loss per rectum a Medline literature search was undertaken. The incidence of this symptom in the general population was reported to be approximately 20 per 100 people per year, the consultation incidence in general practice approximately six per 1000 and the incidence of referral to a medical specialist was estimated to be about seven per 10,000 per year. The clinical significance of the symptom varied within different populations: the predictive value of overt rectal blood loss for colorectal malignancy was estimated to be less than one in 1000 in the general population, approximately two in 100 in general practice and up to 36 in 100 in referred patients. How the manifestation of the bleeding (and other signs and symptoms) contributes to the selection of ...

Objective: To assess the effect of tourniquet application of intraoperative blood loss in placenta accreta cases undergoing cesarean hysterectomy. Materials and methods: Nine cases and twenty controls with USG and colour Doppler diagnosed placenta accreta with previous cesarean section were chosen to utilize this _disibledevent= 0.0002). No intra-operative or post-operative surgical complications were observed in any of the cases whereas the controls reportedly had a few. All the mothers and babies were healthy at the time of discharge. Conclusion: The presence of placenta accreta is associated with major fetal and maternal complications. The technique of tourniquet application is efficacious in minimizing the intra-operative blood loss and surgical complications due to obstruction of operative field by bleeding and also by preventing massive blood transfusion related complications.

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 ...
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
Product Name: Tranexamic Acid Injection. Common Name: antifibrinolytic injection. Strength: 100 mg / ml. Description: Tranexamic acid belongs to the class of medications called antifibrinolytic agents. Tranexamic acid (TXA) is a medication used to treat or prevent excessive blood loss from trauma, surgery, and in various medical conditions including hemophilia and heavy menstrual bleeding. It comes in oral and intravenous forms.. Indications and Usage:. Tranexamic acid medication is used to prevent or reduce bleeding in certain conditions, such as dental surgery in people with hereditary blood clotting disorders, cervical surgery, heavy menstrual bleeding, nose bleeds and bleeding inside the eye.. In some medical conditions, the body breaks down blood clots too fast, not allowing the bleeding to stop and the wound to heal. Tranexamic acid works by blocking the breakdown of clots in the body..

A previously described method by Belanger for posterior fusion of the sacroiliac joint utilizing pedicular instrumentation is presented, suitable for cases with chronic pain. Two patients with nontraumatic disorders of the sacroiliac joint who have undergone successful arthrodesis by this technique are presented. One patient, with poliomyelitis sequels, had sacroiliac disruption secondary to mechanical overloading; the other, had degeneration of the sacroiliac joint. In both cases their fusion remained stable after 3 years follow-up.. The advantage of this technique, using iliac and S1 pedicular screws, is that the screws are relatively easy and rapid to insert. As they are connected to the rod a very stable fixation is achieve and this allows for a low-profil construct. This technique has reduced intra-operative blood loss and operative time.. This method of sacroiliac arthrodesis may be an attractive option for surgeons who are familiar with pedicle screws instrumentation techniques. It should ...
Most of the above-mentioned procedures can be performed with the assistance of robotic technology. Gynecologic surgeons at the University of Florida are proud to utilize the most advanced robotic technology in the world. Two da Vinci Si robotic systems are housed at Shands at UF and are used routinely for a myriad of gynecologic procedures such as hysterectomy, myomectomy, sacrocolpopexy and adnexal surgery. The da Vinci system provides superior 3-D quality visualization and magnification, along with the precision afforded with its unique wristed instruments. Robotic and minimally-invasive approaches offer significant benefits over traditional open surgery, such as less surgical blood loss, less scarring, less pain, better cosmetic results and faster recovery and return to regular activities. Most patients are able to leave the hospital within 24 hours.. ...

Since the successful perioperative use of rhEPO more than 5 years ago in an animal model, many reports (1) have detailed its use in clinical medicine. The investigation by Biesma and colleagues joins a growing list of studies that support the preoperative clinical use of rhEPO as an adjunct to decrease allogeneic (homologous) red blood cell use (1, 2). Their study is also unique in that it helps to define specific groups of patients who may most benefit from preoperative rhEPO, namely, those autologous blood donors with blood volumes , 5 L. Autologous blood collection services currently allow many patients who are having elective surgery to bank their own blood. As much as 60% of the autologous blood collected in the United States, however, does not get transfused. In the study by Biesma and colleagues, 54% (27 of 50) of the patients in the rhEPO-treated group were not transfused with any red blood cells. The cost to the hospital pharmacy for rhEPO is approximately $10 per 1000 units, which ...
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 ...
To the editor: Kobrinsky and associates (1) show that patients receiving 1-desamino-8-D-arginine vasopressin (desmopressin) had a decreased blood loss during Harrington rod spinal fusion surgery. The authors speculate that the decreased blood loss was due to various hematologic effects of desmopressin and conclude that "the use of desmopressin in other surgical procedures associated with significant blood loss is recommended.". This conclusion is probably unwarranted. Intraoperatively "a balanced technique with normotension" was used. Unless specifically contraindicated, induced hypotension with a mean blood pressure of about 70 torr is the accepted anesthetic technique (2). This is done to minimize intraoperative blood loss. ...

5.0603 -42.8239 SADLY, the deaths of 29-year-old conjoined Iranian twins during surgery prove that despite numerous strides in medical science, such delicate and risky surgery has a long way to go.. More than 50 hours into what was to have been four days of surgery in Singapore, Ladan Bijani died. Her sister Laleh died 90 minutes later. Both deaths were blamed on blood loss.. The sisters understood that the risks of surgery were high. Joined at the head, with brains that not only shared a vein but had fused over the years, the women so desperately desired to live separately that they willingly and courageously faced the possibility that one, or both of them, could die in the process.. That should be stressed more than trying to fix blame.. The adoptive father of the two was bitter. "When they took them to Singapore I knew they would bring back their bodies," Alireza Safian said. "They took them there and killed them.". His emotional state is understandable if way off the mark.. Other adult ...

In the acute normovolemic hemodilution group, intraoperative blood collection was performed to a target hemoglobin of 8.0 g/dL. Low central venous pressure anesthetic technique was used intraoperatively for both groups. A standardized transfusion protocol was applied to all patients intraoperatively and throughout the hospital stay.. The researchers randomized 63 patients to acute normovolemic hemodilution, and 67 to standard anesthetic management from 2004 to 2007.. Demographics, diagnoses, liver function, extent of resection, intraoperative blood loss, operative time, incidence and grade of complications, and length of hospital stay were similar between the 2 groups. The team found that acute normovolemic hemodilution reduced the overall allogeneic red cell transfusion rate by 50% compared with standard anesthetic management. Acute normovolemic hemodilution patients were less often transfused intraoperatively compared with the standard anesthetic management group.. The research team noted that ...
UNLABELLED The erythropoietic capacity for preoperative autologous blood donation (ECPABD) shows marked inter individual variability. This study was performed to evaluate factors useful to predict individual ECPABD from data available before the first donation. The subjects consisted of 74 adult patients who received autologous blood donation, with a mean of 61 +/- 12.8 yr (SD). We classified the patients into four groups using our criteria for evaluating the ECPABD and investigated the relationships among age, disease, pre-platelet count, and the rate of platelet increase. RESULTS (1) Advanced age and the status of disease were not distinctly correlated with low ECPABD. (2) Patients with a high pre-platelet levels had a low ECPABD regardless of the haemoglobin. (3) Patients in which the platelet count increased in accordance with the level of collection exhibited low pre-platelet counts and high ECPABD. CONCLUSION In patients with high pre-platelet levels, we reduced the amount collected,
Context: Intraoperative blood loss during open lumbar spine surgery is associated with adverse events and is a contributor to higher medical costs. Intraoperative hypothermia has been shown to increase blood loss and postoperative allogeneic blood transfusion rates in other realms of orthopedic surgery, but it has not been studied extensively in patients undergoing spine surgery. Objective: To determine whether a clinically relevant association exists between intraoperative core body temperature and blood loss or transfusion rates in adult patients undergoing open lumbar spine surgery. Methods: In this retrospective medical record review, the surgical records of 174 adult patients who underwent open, nonmicroscopically assisted lumbar spine surgery performed by a single surgeon at a single institution were evaluated. Maximum, minimum, and average temperature, hypothermic temperature, and temperature range parameters were compared with intraoperative, total, and net blood loss and blood ...
BACKGROUND The objective of this meta-analysis was to evaluate the efficacy and safety of tranexamic acid (TXA) in shoulder arthroplasty (SA). METHODS Academic articles were identified from the Cochrane Library, Medline (1966-2017.2), PubMed (1966-2017.2), Embase (1980-2017.2), and ScienceDirect (1966-2017.2). Randomized controlled trials (RCTs) and non-RCTs studying TXA in SA were included. Two independent reviewers conducted independent data abstraction. The I statistic was used to assess heterogeneity. Fixed- or random-effects models were used for meta-analysis. RESULTS Two RCTs and 2 non-RCTs met the inclusion criteria. This meta-analysis found significant differences in postoperative hemoglobin reduction (MD = -0.71 g/dL), drainage volume (MD = -133.21 mL), and total blood loss (MD = -226.82 mL) between TXA groups and controls. There were no significant differences in blood transfusion requirements, operation time, or length of hospital stay. CONCLUSIONS The use of TXA in SA decreases
Tranexamic acid has been shown to reduce postoperative blood losses and transfusion requirements in various types of major surgery (orthopedic surgery, spine surgery, cardiopulmonary bypass, liver resections, and gynecological cancers).The current trial is being conducted to compare the efficacy of tranexamic acid plus standard of care versus standard of care in reduction of blood loss in patients undergoing major abdominal surgeries ...
Preoperative autologous collections are most beneficial to those patients who are undergoing procedures with substantial anticipated blood loss, such as orthopedic joint replacement, vascular surgery, cardiac or thoracic surgery, and radical prostatectomy. Autologous blood is unnecessary for procedures that seldom require transfusion, such as transurethral resection of the prostate, cholecystectomy, herniorrhaphy, vaginal hysterectomy, and uncomplicated obstetric delivery [14]. A hospitals maximal surgical blood order schedule for blood cross-match can provide estimates of transfusion rates for specific procedures; the generally accepted cutoff at which transfusion is unlikely and autologous blood procurement should not be recommended is 10% [15].. Collection of units should be scheduled as far in advance of surgery as possible for liquid blood storage (up to 42 days), to allow compensatory erythropoiesis [5] to correct the induced anemia. If the erythropoietic response to autologous blood ...
The optimal application of tourniquet should reduce perioperative blood loss, create bloodless operative field, improve cementing technique and shorten surgery time. Meanwhile, inadequate application may increase the risk of deep vein thrombosis and pulmonary thromboembolism. Previous attempts to compare the tourniquet strategies in respect to the perioperative blood loss did not show significant difference. The investigators use the volume loading test aiming to optimize the fluid status and obtain the hemoglobin concentration in the conditions of standardized plasma dilution. The test is deployed just before the surgery and after postoperative 24 hrs in ICU. Functional outcomes and possible length of hospital stay is also evaluated ...
Risk Summary. Available data from published studies, case series and case reports with tranexamic acid use in pregnant women in the second and third trimester and at the time of delivery have not clarified whether there is a drug-associated risk of miscarriage or adverse maternal or fetal outcomes. There are 2 (0.02%) infant cases with structural abnormalities that resulted in death when tranexamic acid was used during conception or the first trimester of pregnancy; however, due to other confounding factors the risk of major birth defects with use of tranexamic acid during pregnancy is not clear. Tranexamic acid is known to pass the placenta and appears in cord blood at concentrations approximately equal to maternal concentration (see Data).. Reproduction studies performed in mice, rats, and rabbits have not revealed any adverse effects on the fetus due to tranexamic acid administered during organogenesis. Doses examined were multiples of up to 3 times (mouse), 6 times (rat), and 3 times ...
