Superior autologous blood stem cell mobilization from dose-intensive cyclophosphamide, etoposide, cisplatin plus G-CSF than from less intensive chemotherapy regimens. (1/329)

The study purpose was to determine if G-CSF plus dose-intensive cyclophosphamide 5.25 g/m2, etoposide 1.05 g/m2 and cisplatin 105 mg/m2 (DICEP) results in superior autologous blood stem cell mobilization (BSCM) than less intensive chemotherapy. From January 1993 until May 1997, 152 consecutive patients with non-Hodgkin's lymphoma (n = 55), breast cancer (n = 47), Hodgkin's disease (n = 14), multiple myeloma (n = 9), AML (n = 9), or other cancers (n = 18) initially underwent BSCM by one of three methods: Group 1: G-CSF alone x 4 days (n = 30). Group 2: disease-oriented chemotherapy, dosed to avoid blood transfusions, followed by G-CSF starting day 7 or 8, and apheresis day 13 or 14 (n = 82). Group 3: DICEP days 1-3, G-CSF starting day 14, and apheresis planned day 19, 20 or 21 (n = 40). A multivariate analysis was performed to determine which factors independently predicted BSCM. The median peripheral blood CD34+ (PB CD34+) cell count the morning of apheresis linearly correlated with the number of CD34+ cells removed per litre of apheresis that day. The median PB CD34+ cell count and median CD34+ cells x 10(6) removed per litre of apheresis were highest for Group 3, intermediate for Group 2, and lowest for Group 1. By multivariate analysis, mobilization group (3 > 2 > 1), disease other than AML, no prior melphalan or mitomycin-C, and less than two prior chemotherapy regimens predicted better BSCM. Out of 15 Group 3 patients who had infiltrated marrows, 11 had no detectable cancer in marrow and apheresis products after DICEP. These data suggest that DICEP results in superior BSCM than less intensive chemotherapy regimens.  (+info)

Autologous versus allogeneic transfusion: patients' perceptions and experiences. (2/329)

BACKGROUND: Preoperative autologous donation is one way to decrease a patient's exposure to allogeneic blood transfusion. This study was designed to determine patients' perceptions about the autologous blood donation process and their experiences with transfusion. METHODS: To assess patient perception, a questionnaire was administered a few days before surgery to patients undergoing elective cardiac and orthopedic surgery in a Canadian teaching hospital. All patients attending the preoperative autologous donation clinic during a 10-month period were eligible. A convenience sample of patients undergoing the same types of surgery who had not predonated blood were selected from preadmission clinics. Patient charts were reviewed retrospectively to assess actual transfusion practice in all cases. RESULTS: A total of 80 patients underwent cardiac surgery (40 autologous donors, 40 nondonors) and 73 underwent orthopedic surgery (38 autologous donors, 35 nondonors). Of the autologous donors, 75 (96%) attended all scheduled donation appointments, 73 (93%) said that they were "very likely" or "likely" to predonate again, and 75 (96%) said that they would recommend autologous donation to others. There was little difference in preoperative symptoms between the autologous donors and the nondonors, although the former were more likely than the latter to report that their overall health had remained the same during the month before surgery (30 [75%] v. 21 [52%] for the cardiac surgery patients and 30 [79%] v. 18 [51%] for the orthopedic surgery patients). When the autologous donors were asked what they felt their chances would have been of receiving at least one allogeneic blood transfusion had they not predonated, the median response was 80%. When they were asked what their chances were after predonating their own blood, the median response was 0%. The autologous donors were significantly less likely to receive allogeneic blood transfusions (6 [15%] for cardiac surgery and 3 [8%] for orthopedic surgery) than were the nondonors (14 [35%] for cardiac surgery and 16 [46%] for orthopaedic surgery). They were, however, more likely to receive any transfusion (autologous or allogeneic) than were the nondonors (25 [63%] v. 14 [35%] for cardiac surgery and 31 [81%] v. 16 [46%] for orthopedic surgery). INTERPRETATION: Patients who underwent preoperative autologous blood donation were positive about the experience and did not report more symptoms than patients who did not donate blood preoperatively. Autologous donors overestimated their chances of receiving allogeneic blood transfusions had they not predonated and underestimated their chances after they had predonated. They were less likely to receive allogeneic transfusions, but more likely to receive any type of transfusion, than were patients who did not predonate.  (+info)

Transfusion practices among patients who did and did not predonate autologous blood before elective cardiac surgery. (3/329)

BACKGROUND: Preoperative autologous blood donation is commonly used to reduce exposure to allogeneic transfusions among patients undergoing elective cardiac surgery. However, this technique is associated with an overall increase in transfusions (allogeneic or autologous). The authors assessed the impact of transfusion decision-making on the effectiveness of preoperative autologous donation in reducing the frequency of allogeneic transfusions, and its impact on the increased transfusion rate associated with preoperative autologous donation in cardiac surgery. METHODS: This retrospective analysis compared transfusion practices among 176 patients who predonated autologous blood before elective cardiac surgery and 176 matched cardiac surgery patients who did not predonate blood. The impact of decision-making on transfusion exposure was determined using multivariate analyses to account for major perioperative interventions and complications. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for exposure to allogeneic blood transfusion or any transfusion, before and after exclusion of transfusions not conforming with selected transfusion criteria. RESULTS: Exposure to allogeneic transfusion was more likely among patients who did not predonate blood than among those who did predonate blood (OR 14.0, 95% CI 5.8-33.8). This finding was still true after exclusion of transfusions not meeting the transfusion criteria (OR 19.3, 95% CI 6.7-55.7). The autologous blood donors were more likely than the nondonors to receive any transfusion (OR 10.8, 95% CI 5.7-20.3). However, this association was substantially attenuated after exclusion of transfusions not meeting the transfusion criteria (OR 1.9, 95% CI 1.1-3.2). INTERPRETATION: Patients who predonated blood before elective cardiac surgery were at lower risk of receiving allogeneic transfusions than the nondonors. This was not because of a deliberate withholding of allogeneic transfusions from autologous donors. However, more liberal transfusion criteria for autologous blood were largely responsible for the increased transfusion rate among the autologous donors.  (+info)

Complement activation and increased systemic and pulmonary vascular resistance indices during infusion of postoperatively drained untreated blood. (4/329)

In nine healthy young patients, operated on for thoracic scoliosis, a pulmonary artery catheter was inserted for the study of haemodynamic variables and blood sampling during autologous transfusion of postoperatively drained blood. At 1-3 h after wound closure, 10 ml kg/body weight of drained untreated blood from the wound was collected and recirculated over a l-h period. The concentration of the complement activation product, C3bc, increased from a mean of 5.4 (SD 1.5) AU ml-1 before infusion to 11.1 (3.9) AU ml-1 during infusion and then returned to 7.8 (2.8) AU ml-1 after infusion. The concentration of the terminal complement complex (TCC) increased from 0.5 (0.2) to 1.3 (0.5) AU ml-1 and was reduced to 0.7 (0.3) AU ml-1 after infusion. Only TCC exceeded the reference values which are 14 AU ml-1 for C3bc and 1.0 AU ml-1 for TCC. Pulmonary vascular resistance index concomitantly increased from a mean of 130 (SD 52) to 195 (88) dyn s cm-5 m-2 and was reduced to 170 (86) dyn s cm-5 m-2 after infusion. Systemic vascular resistance index increased from a mean of 1238 (SD 403) to 1349 (473) dyn s cm-5 m-2 and returned to 1196 (401) dyn s cm-5 m-2 after infusion. White blood cell count (WCC) increased from 14.4 (4.3) x 10(9) litre-1 before infusion to 17.8 (7.2) x 10(9) litre-1 during and after infusion. No change in platelet count during infusion was observed. There were no differences in WCC or platelet count between mixed venous or peripheral arterial blood. Pulmonary and systemic vascular resistance indices may be influenced by activated complement in drained untreated blood when it is recirculated.  (+info)

Haemodynamic assessment of hypovolaemia under general anaesthesia in pigs submitted to graded haemorrhage and retransfusion. (5/329)

We have compared the value of different variables used in the assessment of blood loss during progressive hypovolaemia and resuscitation under general anaesthesia in anaesthetized pigs. We measured mean arterial pressure (MAP), pulmonary capillary wedge pressure (PCWP), the negative component of the systolic arterial pressure variation (delta Down) and left ventricular end-diastolic area (LVEDa) using echocardiography. Blood was progressively withdrawn (up to 35 ml kg-1 in seven steps) and then reinfused after the same pattern. Regression coefficient (r) and normalized slope (nS) of the regression relationship between each variable and amount of blood loss were determined. The difference between the withdrawal and reinfusion curves was assessed by the area between the curves. We also estimated the minimal loss of blood volume which induced significant changes in each variable compared with that under control conditions during withdrawal of blood (minWBV) and maximal loss in blood volume which induced no significant changes in a variable compared with control conditions during retransfusion (maxRBV). During haemorrhage, MAP decreased (from mean 74 (SD 9) to 31 (5) mm Hg; P < 0.001), delta Down increased (from 1.2 (1.4) to 11.4 (4.2) mm Hg; P < 0.001), PCWP decreased (from 6.2 (2.1) to 0.3 (1.0) mm Hg; P < 0.001) and LVEDa decreased (from 13.8 (2.0) to 5.1 (2.0) cm2; P < 0.01). The highest r values were obtained with MAP and LVEDa, and the highest nS value with delta Down. The least difference between withdrawal and reinfusion was with LVEDa, the lowest values of minWBV were with PCWP and LVEDa, and the highest value of maxRBV was obtained with PCWP. During progressive haemorrhage under general anaesthesia, LVEDa was an accurate variable for assessment of blood volume loss, delta Down contributed no further information compared with MAP, and PCWP was the most reliable variable for assessing return to baseline blood volume.  (+info)

Systemic and microcirculatory effects of autologous whole blood resuscitation in severe hemorrhagic shock. (6/329)

Systemic and microcirculatory effects of autologous whole blood resuscitation after 4-h hemorrhagic shock with a mean arterial pressure (MAP) level of 40 mmHg were investigated in 63 conscious Syrian golden hamsters. Microcirculation of skeletal skin muscle and subcutaneous connective tissue was visualized in a dorsal skinfold. Shed blood was retransfused within 30 min after 4 h. Animals were grouped into survivors in good (SG) and poor condition (SP) and nonsurvivors (NS) according to 24-h outcome after resuscitation and studied before shock, during shock (60, 120, and 240 min), and 30 min and 24 h after resuscitation. Microvascular and interstitial PO2 values were determined by phosphorescence decay. Shock caused a significant increase of arterial PO2 and decrease of PCO2, pH, and base excess. In the microcirculation, there was a significant decrease in blood flow (QB), functional capillary density (FCD; capillaries with red blood cell flow), and interstitial PO2 [1.8 +/- 0.8 mmHg (SG), 1.3 +/- 1.3 mmHg (SP), and 0.9 +/- 1.1 mmHg (NS) vs. 23.0 +/- 6.1 mmHg at control]. Blood resuscitation caused immediate MAP recompensation in all animals, whereas metabolic acidosis, hyperventilation, and a significant interstitial PO2 decrease (40-60% of control) persisted. In NS (44.4% of the animals), systemic and microcirculatory alterations were significantly more severe both in shock and after resuscitation than in survivors. Whereas in SG (31.8% of the animals) there was only a slight (15-30%) but still significant impairment of microscopic tissue perfusion (QB, FCD) and oxygenation at 24 h, SP (23.8% of the animals) showed severe metabolic acidosis and substantial decreases (>/=50%) of FCD and interstitial PO2. FCD, interstitial PO2, and metabolic state were the main determinants of shock outcome.  (+info)

A prospective randomized comparison of three blood conservation strategies for radical prostatectomy. (7/329)

BACKGROUND: Preoperative autologous blood donation is a standard of care for elective surgical procedures requiring transfusion. The authors evaluated the efficacy of alternative blood-conservation strategies including preoperative recombinant human erythropoietin (rHuEPO) therapy and acute normovolemic hemodilution (ANH) in radical retropubic prostatectomy patients. METHODS: Seventy-nine patients were prospectively randomized to preoperative autologous donation (3 U autologous blood); rHuEPO plus ANH (preoperative subcutaneous administration of 600 U/kg rHuEPO at 21 and 14 days before surgery and 300 U/kg on day of surgery followed by ANH in the operating room); or ANH (blinded, placebo injections per the rHuEPO regimen listed previously). Transfusion outcomes, perioperative hematocrit levels, postoperative outcomes, and blood-conservation costs were compared among the three groups. RESULTS: Baseline hematocrit levels were similar in all groups (43%+/-2%). On the day of surgery hematocrit decreased to 34% +/-4% in the preoperative autologous donation group (P < 0.001), increased to 47%+/-2% in the rHuEPO plus ANH group (P < 0.001), and remained unchanged at 43%+/-2% in the ANH group. Allogeneic blood exposure was similar in all groups. The rHuEPO plus ANH group had significantly higher hematocrit levels compared with the other groups throughout the hospitalization (P < 0.001). Average transfusion costs were significantly lower for ANH ($194+/-$192) compared with preoperative autologous donation ($690+/-$128; P < 0.001) or rHuEPO plus ANH ($1,393+/-$204, P < 0.001). CONCLUSIONS: All three blood-conservation strategies resulted in similar allogeneic blood exposure rates, but ANH was the least costly technique. Preoperative rHuEPO plus ANH prevented postoperative anemia but resulted in the highest transfusion costs.  (+info)

Perflubron emulsion delays blood transfusions in orthopedic surgery. European Perflubron Emulsion Study Group. (8/329)

BACKGROUND: Fluorocarbon emulsions have been proposed as temporary artificial oxygen carriers. The aim of the present study is to compare the effectiveness of perflubron emulsion with the effectiveness of autologous blood or colloid infusion for reversal of physiologic transfusion triggers. METHODS: A multinational, multicenter, randomized, controlled, single-blind, parallel group study was performed in 147 orthopedic patients. Patients underwent acute normovolemic hemodilution with colloid to a target hemoglobin of 9 g/dl with an inspiratory oxygen fraction (FIO2) of 0.40. Patients were then randomized into one of four treatment groups after having reached any of the protocol-defined transfusion triggers including tachycardia (heart rate > 125% of posthemodilution rate or > 110 bpm), hypotension (mean arterial pressure < 75% of posthemodilution level or < or = 60 mmHg), elevated cardiac output (> 150% of posthemodilution level) or decreased mixed venous oxygen partial pressure (PVO2; < 38 mmHg). Treatments in the four groups were 450 ml autologous blood harvested during acute normovolemic hemodilution given at FO2 = 0.40; 450 ml colloid at FIO2 = 1.0; 0.9 g/kg perflubron emulsion with colloid (total = 450 ml) at FIO2 = 1.0; and 1.8 g/kg perflubron emulsion with colloid (total = 450 ml) at FIO2 = 1.0. The primary endpoint was duration of transfusion-trigger reversal. A secondary end-point was percentage of transfusion-trigger reversal. RESULTS: Perflubron emulsion was well tolerated with no serious adverse event attributed to drug treatment. Duration of reversal was longest in the 1.8 g/kg perflubron group (median, 80 min; 95% confidence interval, 60-100 min; P = 0.014 vs. autologous blood, P < 0.001 vs. colloid) followed by the 0.9 g/kg perflubron group (median, 59 min; 95% confidence interval, 40-90 min), the autologous blood group (median, 55 min; 95% confidence interval, 30-70 min) and the colloid group (median, 30 min; 95% confidence interval, 27-60 min). Percentage of reversal was also highest in the 1.8 g/kg perflubron group (97%; P < 0.001 vs. autologous blood; P = 0.014 vs. colloid), followed by 0.9 g/kg perflubron (82%), colloid (76%), and autologous blood (60%). CONCLUSIONS: Perflubron emulsion (1.8 g/kg) combined with 100% oxygen ventilation is more effective than autologous blood or colloid infusion in reversing physiologic transfusion triggers.  (+info)

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,

N2 - Hemodilution during cardiopulmonary bypass (CPB) is a primary risk factor for blood transfusion in cardiac surgical patients. Priming of the CPB circuit with the patients own blood (retrograde autologous priming, RAP) is a technique used to limit hemodilution and reduce transfusion requirements. We designed this study to examine the impact of RAP on perioperative blood product use. Using a retrospective cohort study design, the medical records of all patients undergoing CPB (excluding circulatory arrest cases) by a single surgeon were examined. Data were collected over a 24-mo period when RAP was routinely used as a blood ...
Objective: Mediastinal bleeding and blood transfusion have been an important accompaniment of open heart surgery. Increasing attempts are being made to minimize blood loss and blood transfusion in cardiac surgery. We investigated the effect of intraoperative autologous donation (IAD) on need for homologous transfusion post-coronary artery bypass graft surgery (CABG).Methods: 202 adult patients scheduled for elective CABG operation were randomly assigned to IAD (n=101) or control groups (n=101). We obtained 500ml fresh whole blood from the IAD patients while the patients were prepared for anesthesia in the operating room. This amount of blood was replaced with Ringers solution. After completion of the operation and neutralization of heparin, this blood was re-infused to the patients. The amount of bleeding and infused blood products were measured and compared in both groups.Results: The present study demonstrated that IAD did not significantly reduce post-operative mediastinal bleeding, although it had
Behaviorally associated changes in neuroconnectivity following autologous umbilical cord blood infusion in young children with autism spectrum disorder
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 ...
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 ...

In an effort to assess the functional and metabolic status of shed blood erythrocytes and the impact of postoperative shed blood reinfusion on allogenic blood requirements and patients blood parameters, analyses of perioperative blood samples were performed in 28 consecutive orthopaedic patients undergoing spinal fusion, in which postoperative shed blood was collected and reinfused with the ConstaVac CBC II device. In comparison with a previous series of 31 patients, this procedure reduced allogenic blood requirements by almost 30% (P , 0.05), without any ...
Autotransfusion is a process wherein a person receives their own blood for a transfusion, instead of banked allogenic (separate-donor) blood. There are two main kinds of autotransfusion: Blood can be autologously pre-donated (termed so despite donation not typically referring to giving to ones self) before a surgery, or alternatively, it can be collected during and after the surgery using an intraoperative blood salvage device (such as a Cell Saver or CATS). The latter form of autotransfusion is utilized in surgeries where there is expected a large volume blood loss - e.g. aneurysm, total joint replacement, and spinal surgeries. The first documented use of self-donated blood was in 1818, and interest in the practice continued until the Second World War, at which point blood supply became less of an issue due to the increased number of blood donors. Later, interest in the procedure returned with concerns about allogenic (separate-donor) transfusions. Autotransfusion is used in a number of ...
Cognitive function was assessed in English-speaking study participants using one of three different tools depending on the age of the patient at the time of assessment: The Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III), the Wechsler Intelligence Scale for Children (WISC-IV), and the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-III). Some patients were assessed with different tools at subsequent visits as they aged during the conduct of the trial.

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 ...
When used as the sole source of transfused blood, the principal advantage of autologous blood transfusion is the avoidance of transmission of infectious agents and the avoidance of the purported adverse immunomodulatory effects of allogeneic transfusion. In the 1990s, however, the risks of transfusion-transmitted diseases have been greatly reduced, and estimates of the cost-effectiveness of pre-operative autologous blood donations now vary between 2470 dollars and 3,400,000 dollars per quality-adjusted year of life saved, depending on assumptions about the existence and magnitude of any adverse immunomodulatory effects of allogeneic transfusion. There is a paucity of randomized controlled trials evaluating the clinical outcomes and the cost-effectiveness of autologous transfusion procedures, and this situation is unlikely to change in the near future because of the difficulties in conducting such trials.

Autologous Blood Injection (ABI), also known as Autologous Conditioned Plasma (ACP) Injection is a medical procedure popularized circa 2000, whereby a patients blood is injected into an area of the body for the purposes of healing.. ABI is most commonly used to treat degeneration of tendons, which may occur in association with small tears. This disorder of tendons is frequently referred to as tendinitis by the public, however is known as tendinosis or tendinopathy in the medical profession. The procedure is usually performed under ultrasound control by a radiologist.[1] The injection of blood contains small cells called platelets, which contain platelet derived growth factor. This substance is thought to promote tendon healing. A variation on the technique is platelet rich plasma (PRP),[2] which is where the whole blood removed from the patient is spun in a centrifuge, separating the cells of the blood. As such a higher concentration of platelets is delivered into the tissue for healing. As ...

An autologous blood transfusion system comprising at least two interconnected blood receptacles, the first of which is evacuated and connected to a suction device for aspirating blood. The second receptacle takes blood from the first by overcoming the vacuum in the first with a greater vacuum in the second without interrupting the ability of the suction device to simultaneously aspirate blood. The second receptacle may comprise a transfer bag for reinfusion into the patient or an infusion set may be connected to the second receptacle to permit simultaneous collection of the blood from the patient and infusion of the blood back into the patient. In either case, the second receptacle is selectively exposed to positive pressure to expel the blood from the second receptacle into the transfer bag or patient. The method includes aspirating blood from the patient and collecting blood in the first receptacle. Blood is thereafter transferred to the second receptacle by increasing the vacuum in the second
Article] Journal of Orthopaedic Trauma. 29(8):349-353, August 2015. (Format: HTML, PDF). Objective: To determine if intraoperative autologous transfusion using a Cell Saver (CS) was routinely indicated for open reduction internal fixation (ORIF) of acetabular fractures, and if so, was there a difference between differing surgical approaches.. Design: Retrospective single-center cohort study.. Setting: University Level 1 trauma center.. Patients/Participants: One hundred forty-five consecutive acetabular fractures using intraoperative autologous transfusion, either treated with an anterior ilioinguinal or a posterior-based Kocher-Langenbeck approach, were compared.. Intervention: Use of CS in ORIF acetabular cases.. Main Outcome Measurements: CS utilization and CS blood return for acetabular ORIF. Mean intraoperative blood loss between the 2 approaches.. Results: CS blood was returned in 29 of the 145 total cases [23/65 anterior (ilioinguinal approach) and 6/80 posterior approach ...
The most common autologous donation is the preoperative donation of blood for possible use by the donor during elective surgery. For example, a person might give one unit of blood each week for up to six weeks before surgery,(because blood can be stored in its liquid form for up to 42 days). Patients cannot make autologous donations after 72 hours prior to their surgery so that the body has enough time to replenish its blood volume before the surgical procedure.. A significant amount of iron is removed with each autologous donation. As a result, iron supplements are often prescribed for patients making autologous donations.. Autologous donation is most often employed in surgery on bones, blood vessels, the urinary tract, and the heart, when the likely need for transfusion is high. Autologous blood accounts for nearly 5 percent of all blood donated. Autologous blood donors must be medically stable patients who are free of infection. There is no age limitation and many children and elderly ...
Autologous blood donation - can we bank on it? Occupational exposure to blood among medical students. Risks to health care workers in developing countries
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 ...

Both of my pre-operative hospital visits are now complete. On the 12th we went to the General Hospital campus for orientation and the Civic Hospital campus for an autologous blood donation (banking my own blood in case a transfusion is needed); today (20th) was my second autologous blood donation. Orientation involved meeting with the anesthetist and the operating room nurses to answer both general and specific questions (in both directions) and get our bearings as to what, where, when, how and why. Thankfully, every lineup was short and we were finished in only 90 minutes, even though four hours were put aside in our schedule based on the advance arrangements..

Total joint replacement surgery such as total hip arthroplasty (THA) and total knee arthroplasty (TKA) is associated with intra- and postoperative blood loss leading to postoperative anemia. This can be subsequently treated with allogeneic blood transfusion [1, 2]. Yet, allogeneic blood transfusions carry the risk of infections and non-infectious transfusion reactions [3]. Therefore, different types of blood saving measures (BSMs) have been developed to reduce blood loss or to increase cell mass to avoid allogeneic transfusions [4].. Many studies on the effectiveness of the frequently used BSMs erythropoietin (EPO) and intra- and postoperative drainage and re-infusion of autologous blood (in short: perioperative blood salvage) in orthopedic surgery have been performed. Reviews and meta-analyses showed that EPO and perioperative blood salvage reduce transfusions. However, the included studies had several limitations such as a retrospective design, small patient numbers and poor methodologically ...
The Cell Saver Elite blood/cell salvage device helps you avoid allogeneic blood transfusions & can sequester platelet-poor and platelet-rich plasma.
Good morning - Hoping that someone has a recent copy of the AABB Standards for Perioperative Autologous Blood Collection and Administration and is willing to check on something for my requestor. We use the Ortho/PAT device for autologous blood transfusion during and after orthopedic surgeries. The question concerns infusion rates and timing. The device manufacturer states that the infusion must be completed within 6 hours from the start of blood collection. However, the blood that is being returned to the patient has been processed, resulting in a more concentrated product. Our current practice is to collect during most of the operative time and to begin infusing toward the end of the 6 hour period. Our clinical educator is concerned about negative impacts on osmotic pressures as we push to complete the transfusion within the allotted time period and is looking for information that either supports this practice or recommends a different approach - such as transfusing smaller amounts more ...

A 40-year-old man was admitted with symptomatic pulmonary stenosis in Takayasu arteritis. Computed tomographic pulmonary angiography demonstrated no blood flow in the left lung and a severe narrowing in the right main pulmonary artery (Figure 1). Pulmonary angiography showed reduced perfusion in the right lung (Figure 2A). Balloon pulmonary angioplasty (BPA) was attempted in the right pulmonary artery, but BPA was ceased because the patient had a seizure during balloon dilation. We suspect that the seizure was triggered by transient loss of blood flow in the brain during balloon dilation, which blocked the only pulmonary artery that connected the right heart and the lungs. To maintain pulmonary blood flow during balloon angioplasty, a 6-F long introducer sheath was advanced to the right pulmonary artery and successfully crossed the lesion to deliver blood, which was collected from the patients atria and anticoagulated with heparin before BPA. The blood was then injected using syringes at a ...

An autotransfusion apparatus for collecting salvaged blood includes an upper chamber for collecting blood and a lower chamber for receiving blood from the upper chamber. The upper chamber is subjected to a vacuum to withdraw blood from a patient. Particles and lipids are removed from the collected blood by a particle filter and a lipid separator. A selector valve located between the vacuum port and the lower chamber, and between the lower chamber and a vent, selectively couples lower chamber either to the vacuum source or the vent. The lower chamber receives blood from the upper chamber through a pressure-operated drain valve only when the lower chamber is coupled to the vacuum source. Coupling the lower chamber to the vent while the upper chamber is subjected to the vacuum source causes a pressure differential between the chambers, closing the pressure-operated drain valve. This allows the upper chamber to remain under a vacuum and continuously collect blood while the lower chamber drains blood
This is not a novel procedure. The first successful autotransfusion on record was conducted in 1818 by James Blundell on a patient suffering from postpartum hemorrhage. Through the end of the 1800s and into the early 1900s, surgeons utilized this technique with surprising success
I got the letter from my surgeons office, saying it is time to set up my blood donations. I am supposed to donate 3 units, starting 34 days prior to surgery. I am having a difficult time finding a center that does this, close to where I live in PA. Also, I have been quoted fees from $148 per unit, to $500 per unit, for them to draw, process, and ship the blood. I am wondering, do most surgeons ask their pts. to do this? And, for those of you who did, how did you feel afterwards. Normally, a
The result of the model calculations are presented in a table given in the appendix for a range of Hi from 0.30 to 0.50 with ANH performed to minimum hematocrits from 0.30 to 0.15. Given a Hi of 0.40, if the Hm is assumed to be 0.25.then from the equation above the RCM count is still high and ANH is not necessary, if BLs does not exceed 2303 ml, since the hemotocrit will not fall below Hm, although five units of blood must be removed during hemodilution. Under these conditions, to achieve the maximum benefit from the technique if ANH is used, no homologous blood will be required to maintain the Hm if blood loss does not exceed 2940 ml. In such a case ANH can save a maximum of 1.1 packed red blood cell unit equivalent, and homologous blood transfusion is necessary to maintain Hm, even if ANH is used. This model can be used to identify when ANH may be used for a given patient and the degree of ANH necessary to maximize that benefit. For example, if Hi is 0.30 or less it is not possible to save a ...
Being a blood donor means that a person allows his or her blood to be drawn so that it can be used at a later time. Sometimes the blood is used by another person, and sometimes the blood is used by the donor herself. Often when a person is scheduled for surgery and has plenty of advance notice, she has the opportunity to bank some of her own blood. This is called an autologous donation. Autologous blood donations do not need to be screened for things like AIDS or hepatitis because the person cannot contract a disease from herself. If she has the disease, she has the disease. If she doesnt, she wont contract it from her own blood. However, if the blood donation is not autologous, it is carefully screened for all types of potential diseases so that the person receiving it does not contract it from the transfusion. Before donating blood, the donor must fill out an extensive questionaire. If the donor has traveled in certain foreign countries recently (where tropical diseases are common, for ...

When an autologous blood product is collected but not transfused, OPPS providers should bill Procedure 86890 (autologous blood or component, collection, processing, and storage; predeposited) or 86891(autologous blood or component, collection, processing, and storage; intra- or postoperative salvage) and the number of units collected but not transfused. Procedure 86890 and 86891 are intended to provide payment for the additional resources needed to provide these services, which are not captured when a blood product HCPCS code is not billed. Because billing 86890 or 86891 is only indicated when autologous blood is collected but not transfused, the OPPS provider should bill 86890 or 86891 on the date when the OPPS provider is certain the blood will not be transfused (i.e., date of a procedure or date of outpatient discharge), rather than on the date of the products collection or receipt from the supplier ...

View more ,A telephone survey of cardiac anaesthetists and perfusionists at the 29 public hospitals providing adult cardiac surgical services in Australia and New Zealand was carried out between December 2019 and January 2020. The aim was to investigate current practice with regard to selected contentious elements of anaesthetic and perfusion management during cardiopulmonary bypass; primarily relating to bypass circuit priming, blood conservation methods and point-of-care coagulation testing. There was a 100% response rate. The average number of adult public cardiopulmonary bypass cases per hospital was 508 (160-1400). For cardiopulmonary bypass cases, ten hospitals (34%) routinely used a cell saver and the remainder used a cell saver selectively. Residual blood remaining in the cardiopulmonary bypass circuit was processed using a cell saver routinely in four hospitals (14%) and selectively in 23 (79%). Acute normovolaemic haemodilution was rarely used. Retrograde autologous priming was used ...
We report on the anesthetic management of a 69-year-old female Jehovahs Witness undergoing cardiopulmonary bypass to replace the ascending aorta; the patient refused transfusion of stored autologous or allogeneic blood products for religious reasons. The strategy involved preoperative hematopoiesis with recombinant human erythropoietin and iron, intraoperative acute normovolemic hemodilution, the use of a cell-saver system, administration of high-dose tranexamic acid, controlled hypotension, avoidance of low body temperature, simplification of the surgery, and lower blood dilution during cardiopulmonary bypass.
Autotransfusion Services is a unique specialty that includes collecting and returning shed blood from the surgical field to significantly reduce or eliminate the need for blood transfusions.
Massive hemorrhage is a recognized complication of PP. The optimal predelivery transfusion planning strategy requires coordination and communication among all perioperative disciplines, including anesthesiologists, obstetricians, nursing personnel, blood bank staff, and interventional radiologists. A massive transfusion protocol should be in place to address preoperative blood component preparation and intraoperative management. Although there is a report on autologous blood donation programs that have reduced the need for allogeneic blood transfusions in high risk parturients, autologous donation is not recommended because severe postpartum hemorrhage is rarely anticipated and problems such as bacterial contamination and human errors exist [31,32]. Hematology and coagulation laboratory values must be evaluated before surgery. The initial measurement of hemoglobin level is useful as a baseline measure and repeated evaluation provides information on the degree of severity of bleeding and anemia ...

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. ...

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 ...

TY - CHAP. T1 - What is the evidence for using hemostatic agents in surgery?. AU - Erstad, Brian L. PY - 2005. Y1 - 2005. N2 - The pharmacological methods used to achieve systemic hemostasis have generated much discussion due to concerns of serious adverse effects (e.g., thromboembolic complications) and costs of therapy in addition to efficacy considerations. There are a limited number of well-controlled trials involving pharmacological hemostasis for spine surgery. In the largest doubleblinded randomized controlled trial to date involving spine surgery, there was a trend toward reduced homologous transfusion in patients receiving aprotinin, but the only statistically significant result (p,0.001) was a reduction in autologous red cell donations. The findings of this trial are important, since the investigators used a number of restrictive transfusion strategies (e.g., autologous donation, low hematocrit trigger for transfusion, blood-salvaging procedures with the exception of no cell saver) ...

Then these tubes are connected to Y connector through the roller cum stripper and 5 clamps and the same is then connected to the gauze needle covered with needle safety shield. The transfusion bag is provided with a Rotary shaker for the mixing of the solution with blood so that the time of the clinicians can be saved. Alternatively, a printed scale is provided on b side of the bag, and one S hook is provided at the lowest part of the bag which helps to collect blood in the OT without the help of any ...
The transfusion laboratories of 32 cardiothoracic surgical centres for adults were surveyed to determine the donor blood requirement for open heart surgery in the United Kingdom. Details of the transfusion practice and the use of blood conservation techniques were sought from a representative senior cardiac anaesthetist at each centre. Suitable data were received from 24 transfusion laboratories (75%) and 29 anaesthetists (90%). The mean (SD) blood use was 5.07 (1.53) units per operation. Seven centres routinely transfused fresh frozen plasma to all patients postoperatively. Experience with autologous deposit (three centres), cell separators (four centres), and the reinfusion of shed mediastinal blood (four centres) was limited. Prebypass phlebotomy for postbypass reinfusion (14 centres) and the infusion of residual oxygenator blood (27 centres) were the conservation techniques most commonly applied. In only nine centres was a postoperative normovolaemic anaemia to a haemoglobin concentration ...
To the editor: We are concerned that recommendations in the Brief Report Anti-A Hemolytic Transfusion with Packed O Cells (1) in the October 1978 issue do not represent a practical approach to the clinical problem that is described. Having observed the very rare event of a nonanaphylactic hemolytic episode in a type A1 recipient of a unit of type O Red Blood Cells (packed cells), Dr. Inwood and Mr. Zuliani recommend that clinicians rigidly accept the principle that only ABO homologous blood should be transfused to patients. Alternatively, the authors recommend that if circumstances demand, either the group O cells ...
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 ...

  • Group A received autologous whole blood transfusion. (
  • METHODS: This is a multi-institutional retrospective study of all trauma patients who received autologous whole blood transfusion from hemothorax from two Level I trauma centers. (
  • Among the elements transfused, in addition to whole blood, are packed red blood cells, plasma, platelets, granulocytes and cryoprecipitate, a plasma protein rich in antihemophilic factor VIII. (
  • These components include plasma, red blood cells (RBCs), white blood cells (WBCs) and platelets. (
  • The survey included questions about donor blood collection methods and product types, importation of blood products for routine use, blood use, and extent of PRT implementation for platelets and plasma. (
  • Transfusion medicine has evolved over many years, and current practice focuses on collection, storage and administration of component parts of whole blood, specifically, red blood cells, plasma and platelets. (
  • Jehovah's Witnesses' literature teaches that their refusal of transfusions of whole blood or its four primary components-red cells, white cells, platelets and plasma-is a non-negotiable religious stand and that those who respect life as a gift from God do not try to sustain life by taking in blood, [4] [5] even in an emergency. (
  • This includes the use of red blood cells , white blood cells , platelets and blood plasma . (
  • Transfusion of allogeneic whole blood, or of its constituents of red cells, white cells, platelets or plasma. (
  • Platelets , the smallest blood cells, help to clot the blood and control bleeding. (
  • The following procedures and products are not prohibited, and are left to the decision of individual members: Blood donation strictly for purpose of further fractionation of red cells, white cells, platelets or plasma for either allogeneic or autologous transfusion. (
  • Platelet Gel, blood is withdrawn and put into a solution rich in platelets and white blood cells. (
  • Measures introduced in Australia and elsewhere to minimise bacterial contamination include diversion pouches used during donor blood collection, and routine pre-release bacterial screening of platelets. (
  • More than 2,700 patients receive blood transfusions each year at Children's National's hospital and Regional Outpatient Centers, including approximately 7,500 red blood cells, 2,000 plasma, 3,000 platelets and 900 cryoprecipitate units. (
  • This treatment reduces the number of platelets in your blood. (
  • In conclusion, RAP is compared with cCPB and MECC a safe and low-cost technique in reducing the priming volume of the CPB system, causes less hemodilution, and reduces the need for intra- and postoperative blood transfusion. (
  • Homologous blood transfusion (HBT) in pediatric cardiac surgery is used most commonly for priming of cardiopulmonary bypass (CPB) system and for postoperative transfusion. (
  • The neonate's autologous cord blood was used for postcardiac surgery blood transfusion to replace postoperative blood loss. (
  • The donor exposure in age and type of cardiac surgery-matched controls showed that the neonates not receiving autologous cord blood had a donor exposure to 5 donors (2 packed red blood cells [PRBCs], including 1 for CPB prime and 1 for postoperative loss, 1 fresh frozen plasma, 1 cryoprecipitate, and 1 platelet concentrate) compared to 1 donor for the AUCB neonate (1 PRBC for the CPB prime). (
  • Postoperative blood loss was similar in both the groups of matched controls and study group. (
  • Conclusions: Use of AUCB for replacement of postoperative blood loss after neonatal cardiac surgery is feasible and reduces donor exposure to the neonate. (
  • We have assessed the effect of the donation of autologous blood and the preoperative level of haemoglobin on the prevalence of postoperative thromboembolism in 2043 patients who had a total hip arthroplasty. (
  • Of those who had donated blood, 0.3% developed a postoperative pulmonary embolism compared with 0.7% in those who had not, but this difference was not statistically significant. (
  • Taken together, H19 accelerated fibroblast activation by recruiting EZH2-mediated histone methylation and modulating the HIF-1α signaling pathway, whereby augmenting the process of modified preservative fluid preserved autologous blood enhancing the postoperative wound healing in diabetic mice. (
  • The objectives of the present study were to investigate the oxygen delivery capacity of autotransfused shed mediastinal blood, compared to patient-blood, during cardiopulmonary bypass and in the postoperative period. (
  • Mediastinal shed blood was collected in the cardiotomy reservoir and retransfused during the first 18 postoperative hours. (
  • Evidence from a variety of sources indicates that allogeneic blood transfusion enhances the survival of renal allografts 1 and may increase the recurrence rate of resected malignancies 2 and the incidence of postoperative bacterial infections, 3-7 as well as reduce the recurrence rate of Crohn disease 8 and/or activate infections with cytomegalovirus 9 or human immunodeficiency virus. (
  • A subsequent hypothesis proposed that, if allogeneic blood transfusion causes immunosuppression, then recipients of perioperative allogeneic blood transfusion could be at increased risk for postoperative bacterial infection. (
  • Since 1981, more than 150 clinical studies have examined the association of perioperative allogeneic blood transfusion with cancer recurrence and/or postoperative bacterial infection. (
  • Between 15 December 2003 and 21 November 2008, 24 children with T1D (10 males, 14 females) underwent a single autologous UCB transfusion. (
  • Comprehensive Blood Management is a nationally recognized blood management provider comprised of certified clinical perfusionists and specialized healthcare professionals who safeguard and adhere to best practices in autotransfusion, perfusion, platelet rich plasma (PRP), stem cell therapy (BMAC), and blood conservation strategies. (
  • When someone donates their blood for their own use, it is called autologous blood donation or autotransfusion. (
  • The aim of this study was to assess outcomes in trauma patients receiving whole blood autotransfusion (AT) from hemothorax. (
  • This survey of autologous blood transfusion practices, promoted by the Italian Society of Transfusion Medicine and Immunohaematology more than 2 years after the publication of national recommendations on the subject, was intended to acquire information on the indications for predeposit in Italy and on some organisational aspects of the alternative techniques of autotransfusion. (
  • Autotransfusion after open heart surgery: the oxygen delivery capacity of shed mediastinal blood is maintained. (
  • Autotransfusion of mediastinal shed blood after open heart surgery has become a common and accepted procedure in reducing the need for homologous transfusion during the last 15 years. (
  • Shed blood had a mean haemoglobin level of 8.8 g/dl and 7.4 g/dl at 1 h and 6 h of autotransfusion, respectively. (
  • There were no significant changes of 2,3-DPG concentration in the patient-blood during cardiopulmonary bypass or after autotransfusion compared to preoperative values. (
  • The results demonstrate that the oxygen delivery capacity of shed mediastinal blood is maintained and that the oxygen affinity of patient-blood is not influenced by autotransfusion. (
  • Although blood donated by the general public and used for most people is thought to be very safe, some people choose a method called autologous blood donation. (
  • This is called autologous blood donation. (
  • Some basic criteria are used to ensure that blood donation is safe for recipients and donors. (
  • Also, blood centers keep a list of unsafe donors. (
  • Blood from these donors must be collected at least a few days before it is needed. (
  • We are a nonprofit hospital obtaining our blood products through another nonprofit blood bank which collects blood through volunteer donors. (
  • Because of the potential for transfusion-associated transmission of Zika virus, the Food and Drug Administration (FDA) has recommended deferral of blood donors in affected U.S. areas until blood donations can be screened by nucleic acid testing or blood products can be subjected to FDA-approved pathogen reduction technology (PRT). (
  • Donors answer very direct questions about risk factors for infections that can be passed on through their blood. (
  • Blood centers keep a list of donors who may not be safe. (
  • Directed donor blood allows the patient to receive blood from known donors. (
  • People with Type O, negative blood are considered universal donors as it is safe to transfuse to nearly everyone. (
  • There's no medical proof that blood from directed donors is any safer than blood from volunteer donors. (
  • 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. (
  • The University of Rochester receives its supply of blood from healthy donors who give to the American Red Cross. (
  • Since 2004, PEPFAR has provided support (including policy guidance, strengthening laboratory capacity, and enhancing recruitment and retention of safe blood donors) to national blood transfusion services in 14 countries* heavily impacted by HIV. (
  • Peripheral blood stem cell (PBSC) collection is a procedure where volunteer donors (relatives or siblings) or patients donate their stem cells through apheresis for allogeneic and autologous blood and marrow transplantation. (
  • 2. The collection and reinfusion into the patient of blood lost during an operation. (
  • Due to the lack of studies related to the use of autologous blood transfusions in goats, this study was conducted to evaluate the clinical, hematological, and biochemical changes following blood collection and reinfusion in goats. (
  • The clinical, haematological and biochemical parameters were evaluated before blood collection and reinfusion, after 10 minutes of collection and reinfusion, after 3, 6, 12, 24, 48, 96 and 192 hours after collection and reinfusion. (
  • Intraoperative autologous blood collection and reinfusion (Cell Saver or cell salvaging), which occurs when blood you lose during surgery is collected, washed, filtered, and reinfused. (
  • Larger randomized studies as well as 2-year postinfusion follow-up of this cohort are needed to determine whether autologous cord blood-based approaches can be used to slow the decline of endogenous insulin production in children with type 1 diabetes. (

  • illustrate the clinical and fiscal benefits of institution of a multi-disciplinary intraoperative autologous blood donation program. (
  • We investigated the effect of intraoperative autologous donation (IAD) on need for homologous transfusion post-coronary artery bypass graft surgery (CABG). (
  • Laparoscopic myomectomy was successfully performed with local injection of vasopressin and intraoperative autologous blood transfusion. (
  • On the basis of preclinical efficacy and safety data, we performed an unblinded observational pilot study to determine whether autologous UCB infusion could preserve remaining endogenous insulin production. (
  • Baseline and post-infusion mixed meal tolerance tests were performed to determine whether autologous cord blood infusion preserved endogenous insulin production. (
  • RESEARCH DESIGN AND METHODS Fifteen patients diagnosed with type 1 diabetes and for whom autologous umbilical cord blood was stored underwent a single intravenous infusion of autologous cells and completed 1 year of postinfusion follow-up. (
  • Legitimate autologous transfusion is also used by patients awaiting elective surgical procedures as a way of reducing the risks associated with homologous transfusions - transfusions of blood from a blood donor. (
  • Effect of perioperative autologous versus allogeneic blood transfusion on the immune system in gastric cancer patients. (
  • Allogeneic blood transfusion-induced immunomodulation (TRIM) and its adverse effect on the prognosis of patients treated surgically for cancer remain complex and controversial. (
  • The purpose was to further evaluate the effect of autologous versus allogeneic blood transfusion on immunological status in patients undergoing surgery for gastric cancer. (
  • Sixty ASA I-II (American Society of Anesthesiologists) patients undergoing elective radical resection for stomach cancer were randomly allocated to receive either allogeneic blood transfusion (n=30) or autologous blood transfusion (n=30). (
  • Autologous blood transfusion might be significantly beneficial for immune-compromised patients in the perioperative period, clearly showing its superiority over allogeneic blood transfusion. (
  • RESEARCH DESIGN AND METHODS A total of 24 T1D patients (median age 5.1 years) received a single intravenous infusion of autologous UCB cells and underwent metabolic and immunologic assessments. (
  • Zurück zum Zitat Fenwick JC, Cameron CM, Ronco JJ, Wiggs BR, Tweeddale MG, Naiman SC, Haley LP (1994) Blood transfusion as a cause of leucocytosis in critically ill patients. (
  • A total of 86 patients were studied, with 43 using standard suction drains (normal drain group) and 43 using autologous drains (autologous drain group). (
  • A number of studies have showed a decreased incidence of post-operative infections in patients receiving autologous salvaged blood as compared to patients receiving homologous blood or autologous washed blood. (
  • Lancet, 2004) show an increase of Natural Killer Cell Precursors in patients receiving autologous filtered blood, suggesting that the blood contains immunostimulants. (
  • Patients receiving washed autologous blood or homologous blood showed a decrease in Natural Killer Cell Precursors. (
  • We investigated the predictors of blood component usage during elective cardiac surgery in patients prepared with PAD. (
  • Results: Allogenic blood transfusion was avoided during and after surgery in 107 patients (75%), whereas 36 patients required an allogenic transfusion (4.1 ± 3.8 U of packed red cells, 3.4 ± 4.1 U of fresh frozen plasma, and 5.8 ± 11.0 U of platelet concentrate). (
  • The independent factors for perioperative allogenic blood transfusion in these patients included the pre-donation hemoglobin value, the preoperative platelet count, and the lowest hemoglobin value during cardiopulmonary bypass. (
  • Conclusion: Even with PAD for elective cardiac surgery, patients whose pre-donation hemoglobin value and preoperative platelet count are low may require allogenic blood transfusion. (
  • However, new evidence supports the use of whole blood therapy for patients suffering hemorrhage from trauma or surgery. (
  • We obtained 500ml fresh whole blood from the IAD patients while the patients were prepared for anesthesia in the operating room. (
  • After completion of the operation and neutralization of heparin, this blood was re-infused to the patients. (
  • Patients who received AT had significantly lower packed red blood cell (p = 0.01) and platelet requirements (p = 0.01). (
  • Participants will be able to manage patients receiving blood and blood components, including the identification of adverse reactions, and indications and contraindications for use. (
  • Before planned surgery, patients may choose autologous donation in order to avoid the small, but potential, risks of receiving an allogeneic blood transfusion. (
  • This study examined the perceived risks of allogeneic blood transfusions, preferences and willingness to pay for autologous donation and the desired role in the decision-making process in three populations: post-surgical patients, special interest group members and the general public. (
  • Objective To explore the effects of autologous blood transfusion on coagulation function,in-flammatory factors and immune function in patients with traumatic brain injury . (
  • Analysis of total blood product support for a 1‐year cohort of patients undergoing hip or knee total joint arthroplasty showed significant differences in transfusion therapy between patients who predeposited autologous blood and those who did not. (
  • In primary joint arthroplasty, 51% of nonpredepositing patients undergoing hip replacement and 28% of nonpredepositing patients undergoing knee replacement required red cell transfusions. (
  • Predepositors receiving supplemental allogeneic blood used a volume of red cells comparable to nonpredepositing patients, which was significantly greater than the red cell requirement of predepositors using only autologous blood. (
  • Despite differences in admission and lowest observed hematocrits, all patients were discharged with hematocrits in the same range, suggesting that men were replaced with relatively less blood than women. (
  • However, blood from patients with sickle cell disease is difficult to store. (
  • Patients with sickle cell disease can be given hypotensive anesthesia and autologous transfusions of blood donated before surgery and blood salvaged during surgery using a cell-saving device. (
  • Before skin suture, randomization was performed, and 16 patients were injected with 10 mL PRP (10 times higher platelet concentration than peripheral blood) whereas 14 were not. (
  • The number of patients who had donated autologous blood (1037) was similar to that who had not (1006). (
  • Transfusion of your own blood (autologous) is the safest method, but requires planning and not all patients are eligible. (
  • The following material is provided to all patients and/or their family members regarding blood transfusions and the use of blood products. (
  • Although in most situations the likelihood of a blood transfusion associated with surgery is uncommon, at times patients may require blood products. (
  • These two modalities affect not only the cancer affected cells, but also the normal cells Now in AIET, specific types of cells mainly the NK cells and T lymphocytes are isolated from the peripheral blood of the cancer patients (during remission in patients who undergo chemotherapy) by proven methods, expanded to 25-30 fold and activated and then reinfused back into the patient's body. (
  • So most patients receive blood donated through blood drives. (
  • While patients are likely to feel a brief pinch of the needle, a blood transfusion is mostly painless. (
  • Autologous bone marrow transplants have been used successfully for patients undergoing high dose chemotherapy, and for a variety of cancers and autoimmune disorders such as multiple sclerosis, lupus, and rheumatic disorders. (
  • Doctors and patients are often greatly concerned about transfusion-transmitted viruses such as HIV and hepatitis. (
  • Granulocyte transfusions are indicated to protect neutropenic patients from infections. (
  • In normal medical practice, patients may undergo blood transfusions to replace blood lost due to injury or surgery. (
  • Transfusions also are given to patients who suffer from low red blood cell counts caused by anemia , kidney failure, and other conditions or treatments. (
  • Major spinal surgery in adult patients is often associated with significant intraoperative blood loss. (
  • All patients who received ROTEM-guided therapy (ROTEM group) were matched with historical cohorts whose coagulation status had not been evaluated with ROTEM but who were treated using a conventional clinical and point-of-care laboratory approach to transfusion (Conventional group). (
  • Out of 22 patients aged 12 - 35 years, 15 patients achieved transfusion-free status, while others needed transfusions less often. (
  • We saw remarkable outcomes using LentiGlobin gene therapy, with most patients no longer needing monthly transfusions," said leading author Alexis Thompson, MD, Head of Hematology and Director of the Comprehensive Thalassemia Program at Ann & Robert H. Lurie Children's Hospital of Chicago, as well as Professor of Pediatrics at Northwestern University Feinberg School of Medicine. (
  • Since we saw such positive results, we are now enrolling patients as young as 5 years old on a Phase 3 trial of gene therapy for transfusion-dependent thalassemia. (
  • Preoperative banking of the blood of patients planning total hip replacement is considered when possible. (
  • On the basis of the immunomodulatory effect of allogeneic blood transfusion in renal allograft recipients, Gantt 14 raised the question in 1981 whether the TRIM effect might also be associated with an increased risk of cancer recurrence in patients undergoing resection of a malignancy. (
  • Most of these are observational cohort studies comparing patients who had or did not have transfusion. (
  • Meeting the needs of patients while minimizing blood transfusions requires special expertise, precise monitoring and innovative techniques. (
  • Autologous BMT at Children's is performed for patients with cancer. (
  • to increase the amount of blood that patients with moderate anaemia can self-donate before surgery, so that their own blood can be given back to them during or after surgery. (
  • to reduce the need for blood transfusions in patients with moderate anaemia about to undergo major bone surgery (such as a hip or knee replacement). (
  • Erythropoietin is also used before surgery to increase the number of red blood cells to help patients produce more blood for self-donation. (
  • Retacrit, injected into a vein, was compared with the reference medicine in two main studies involving 922 patients who had anaemia associated with chronic renal failure requiring haemodialysis (a technique for removing waste products from the blood). (
  • The first study compared the effects of Retacrit with those of Eprex / Erypo in correcting red blood cell counts in 609 patients over 24 weeks. (
  • The second study compared the effects of Retacrit with those of Eprex / Erypo in maintaining red-blood-cell counts in 313 patients. (

  • Her family's religious convictions precluded homologous transfusions. (
  • Homologous transfusions. (
  • 1. The collection of a patient's own blood before surgery, to be used if the patient needs a transfusion during or after the surgery, to reduce the possibility of needing banked blood, and with it the risk of having a transfusion reaction or contracting a transmissible infection. (
  • Their blood is carefully screened for infection. (
  • White blood cells help the body fight infection by making antibodies, (proteins that help destroy germs in the body). (
  • White blood cells help defend the body against infection by producing antibodies, which help destroy foreign germs in the body. (
  • While historically the focus has been on prevention of transfusion-transmitted infection, other major hazards have been highlighted through haemovigilance programs. (

  • As a final check, a blood bank technologist will mix a small sample of your child's blood with a small sample of the donor blood to confirm they are compatible. (
  • It also reduced the need for allogeneic transfusions and decreased hospital costs. (
  • Blood conserving techniques are an important aspect of limiting transfusion requirements. (
  • Preoperative autologous blood donation in total-hip arthroplasty. (
  • Recent studies focus on the positive effects autologous salvaged blood has on the immune system, as opposed to both homologous and autologous washed blood. (
  • CONCLUSIONS Autologous UCB infusion in children with T1D is safe and induces changes in Treg frequency but fails to preserve C-peptide. (
  • The second receptacle may comprise a transfer bag for reinfusion into the patient or an infusion set may be connected to the second receptacle to permit simultaneous collection of the blood from the patient and infusion of the blood back into the patient. (
  • The purpose of this study is to test the safety and effectiveness of a cord blood infusion in children who have motor disability due to cerebral palsy (CP). (
  • The subjects will be children whose parents have saved their infant's cord blood, who have non-progressive motor disability, and whose parents intend to have a cord blood infusion. (
  • The purpose of this study is to conduct an observer-blinded crossover investigation of the safety and efficacy of autologous cord blood infusion in children who demonstrate non-progressive motor disability due to brain dysfunction (commonly called cerebral palsy) and who do not have an apparent disorder of brain development or obstructive hydrocephalus. (
  • Confirm the efficacy of autologous cord blood infusion in children with cerebral palsy using patient questionnaire and standardized Gross Motor Function Measure evaluation. (
  • Allogeneic blood transfusion results in the infusion into the recipient of large amounts of foreign antigens in both soluble and cell-associated forms. (
  • CONCLUSIONS Autologous umbilical cord blood transfusion in children with type 1 diabetes is safe but has yet to demonstrate efficacy in preserving C-peptide. (
  • Unfortunately, even after PAD, allogenic blood transfusion is not always avoided. (
