Statistical models which describe the relationship between a qualitative dependent variable (that is, one which can take only certain discrete values, such as the presence or absence of a disease) and an independent variable. A common application is in epidemiology for estimating an individual's risk (probability of a disease) as a function of a given risk factor.
Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER).

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.

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)
The platelet level indicates the erythropoietic capacity for preoperative autologous blood donation. - Semantic Scholar
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

Time Trial Performance Is Sensitive to Low-Volume Autologous Blood Transfusion - Forskning - Region Hovedstaden
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 ...

Autotransfusion - Wikipedia
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 ...

Autologous blood donation | Critical Care | Full Text
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 . 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% .. 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  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 - Wikipedia
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. 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), 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 ...

Patente US4006745 - Autologous transfusion system and method - Google Patentes
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

NewYork-Presbyterian/Queens - Transfusion Primer
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 ...

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 ...

De-implementation of expensive blood saving measures in hip and knee arthroplasties: study protocol for the LISBOA-II cluster...
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 . Therefore, different types of blood saving measures (BSMs) have been developed to reduce blood loss or to increase cell mass to avoid allogeneic transfusions .. 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 ...

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 ...

Transcatheter Autologous Transfusion to Maintain Pulmonary Circulation During Balloon Pulmonary Angioplasty | JACC:...
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 ...
US5634893A - Autotransfusion apparatus - Google Patents
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

Hemodynamics - Wikipedia
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 ...

Evidence suggests that local anaesthesia after total knee replacement (TKR) provides better knee function in the postoperative period with less post-operative complications like nausea and vomiting as compared to conventional ways of pain treatment (i.e.opioids). Good clinical results have been obtained with and without the use of indwelling catheters. The Bellovac ABT system; a technique to collect, filter and reinfuse blood and tissue fluid, is also often used in TKR. Bellovac ABT is used as an alternative to allogeneic blood transfusion. A combination of both techniques however, is not common yet. Before routinely combining local anaesthesia with the Bellovac technique we want to quantify the amount of local anaesthetic (if any) in the collected and retranfusable blood and tissue fluid. On the basis of these data the safety of combining local anaesthesia with the retransfusion of blood and tissue fluid will be assessed ...

A directed (or designated) blood donation is one in which a person donates blood that is reserved (at the time of donation) for the transfusion of a specific patient at a later date. The donor is usually a family member or a close friend that has been chosen by the patients family. Consult your childs health care provider if you are interested in learning more about directed donation. It is recommended that families donate in the childs name versus directed donation, because if directed blood is not needed, it is wasted. Blood must be donated within a month of the surgery. If not used, it will be released. An autologous donation is blood collected from the patient in advance of planned surgery.. ...

Anesthetic management for ascending aorta replacement in a patient who refused autologous transfusion for religious reasons -...
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.

Management of massive hemorrhage in pregnant women with placenta previa
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 ...

GastroHep News Story
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) ...

AU - Petersen, John R.. PY - 1993. Y1 - 1993. N2 - A sensitive radioimmunoassay (RIA) for the detection of erythropoietin (EPO) was developed using antibody directed against EPO from human urine. With 100 μL of sample, the assay is sensitive to 7 U/L, well below the mean EPO level in normal males (15.1 ± 3.5 U/L) or females (15.4 ± 4.8 U/L). Dilutions of a variety of human serum samples show a parallel relationship with the standard EPO. Clinical validation of the RIA was confirmed by appropriate increases or decreases of EPO levels in various types of anemia and polycythemia. Serum EPO levels were also measured in volunteers participating in an autologous blood donation study. The RIA proved to eb quite sensitve, detecting small increases even after a single unit phlebotomy. This RIA of human EPO meets all the ...

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 ...
Improving Blood Transfusion Consent - Mediware Information Systems
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 ...

- Blood doping is the practice of boosting the number of red blood cells in the bloodstream in order to enhance athletic performance. (wikipedia.org)
- Because such blood cells carry oxygen from the lungs to the muscles, a higher concentration in the blood can improve an athlete's aerobic capacity (VO2 max) and endurance. (wikipedia.org)
- Blood doping can be achieved by making the body produce more red blood cells itself using drugs, giving blood transfusions either from another person or back to the same individual, or by using blood substitutes. (wikipedia.org)
- Myo-inositol trispyrophosphate (ITPP), also known as compound number OXY111A, is an allosteric effector of hemoglobin which causes a rightward shift in the oxygen-hemoglobin dissociation curve, increasing the amount of oxygen released from red blood cells into surrounding tissue during each passage through the cardiovascular system. (wikipedia.org)
- Transfusion with labeled, autologous, fresh red blood cells. (oregonstate.edu)
- Haemoglobin is the protein in red blood cells that carries oxygen around the body. (europa.eu)

- who is on Chemotherapy and has very low Wht blood cells? (artscolumbia.org)
- Dr. Walters collected stem cells from transfusion-dependent beta-thalassemia major patients, inserted the healthy gene, and then infused the cells back into the patient after first giving high-dose chemotherapy to destroy the thalassemia-producing blood cells. (healthcanal.com)
- Thalassemia is an inherited disorder that affects the production of normal hemoglobin (a type of protein in red blood cells that carries oxygen to the tissues of the body). (childrensnational.org)
- Patients who received AT had significantly lower packed red blood cell (p = 0.01) and platelet requirements (p = 0.01). (elsevier.com)
- Values of hemoglobin, total leukocyte count, platelet counts, and blood gas parameters were also similar. (who.int)
- 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. (nih.gov)
- Platelet concentrates may be derived either from single units of whole blood or by using a cell separator. (hubpages.com)
- BACKGROUND: The practice of transfusing ones' own shed whole blood has obvious benefits such as reducing the need for allogeneic transfusions and decreasing the need for other fluids that are typically used for resuscitation in trauma. (elsevier.com)
- It also reduced the need for allogeneic transfusions and decreased hospital costs. (elsevier.com)
Limiting transfusion requirements1
- Blood conserving techniques are an important aspect of limiting transfusion requirements. (medicinenet.com)
- We obtained 500ml fresh whole blood from the IAD patients while the patients were prepared for anesthesia in the operating room. (org.ir)
- 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. (mdedge.com)
Stem cell trans1
- Treatment with LentiGlobin® is given as an autologous stem cell transplant. (healthcanal.com)
- Alternative techniques (acute isovolaemic haemodilution and peri-operative blood salvage) are used at different frequencies across the country. (elsevier.com)
- Autologous PRP stimulates healing of acute Achilles tendon ruptures. (nih.gov)
- In most other instances, the person cannot donate their own blood due to the acute nature of the need for blood. (medicinenet.com)
- Conclusions: It seems that IAD can reduce homologous blood transfusion (although not significantly), but for prevention of bleeding some simple points such as mild hypothermia instead of moderate hypothermia, reduced heparin dose with newer tubing systems and oxygenators and precise hemostasis are more prominent. (org.ir)
Sickle cell di1
- People with cancer may donate their own blood in case they need a blood transfusion during or after surgery or an invasive procedure. (cancer.ca)
- A blood transfusion is a safe and common procedure during which you receive blood through an intravenous (IV) line placed in one of your blood vessels. (medlineplus.gov)
- A blood transfusion is a fairly simple medical procedure. (kidshealth.org)
- If your child needs a blood transfusion, the doctor will speak with you about the procedure. (kidshealth.org)
- The procedure is similar to a blood transfusion. (stjude.org)
- According to the results of our study, autologous blood transfusion is an efficient method that reduces allogeneic blood usage significantly in our circumstances as well. (thefreedictionary.com)
- Results: The present study demonstrated that IAD did not significantly reduce post-operative mediastinal bleeding, although it had a positive effect on reducing homologous transfusion. (org.ir)
- Cost of transfusions (p = 0.01) was significantly lower in the AT group compared with the No-AT group. (elsevier.com)
- P50 for oxygen (3.6 and 3.6 kPa) and 2,3-DPG concentrations (5.3 and 5.1 mikromol/ml erythrocyte) in shed mediastinal blood (1h and 6h postoperatively) were not significantly different compared to patient-blood. (biomedsearch.com)
