Preoperative autologous blood donation in patients undergoing open heart surgery

We examined the possibility to avoid the homologous blood transfusion in patients undergoing open heart surgery by predonation of 200 ml or 400 ml on the day before operation. Between March 1999 and December 2001, 117 patients underwent scheduled open heart surgery. In these patients, preoperatively collected autologous blood on the day before operation amounted 200 ml or 400 ml. We divided these patients into 3 groups according to the necessity of homologous blood, no transfusion (group A, n = 77), intraoperative transfusion (group B 1, n-29) and postoperative transfusion (group B 2, n = 11). In 65.8% of patients the homologous blood transfusion could be avoided. Preoperative, intraoperative and postoperative factors were compared in the 3 groups. Especially, old age, female, body weight and preoperative hemoglobin value were significantly different between 3 groups. Postoperative Svo2 and postoperative hemoglobin value were significantly different between 3 groups. The purpose of this study was to evaluate that the predonation of 200 ml or 400 ml on the day before operation may be to avoid the homologous blood transfusion and that preoperative, intraoperative and postoperative factors in regard to homologous blood transfusion.     

Intraoperative autologous blood salvage with cardiac surgery: an analysis of five years' experience in more than 3,000 patients.

STUDY OBJECTIVE: To analyze intraoperative autologous salvage of shed mediastinal blood and subsequent transfusion in cardiac surgery. DESIGN: Retrospective statistical analysis. SETTING: University hospital. PATIENTS: Three thousand twenty two patients undergoing cardiac surgery from 1984 to 1988. INTERVENTIONS: A review of anesthesia and transfusion records of all patients who underwent intraoperative salvage of shed blood and autologous transfusion using the Sorenson Receptal Auto Transfusion System (ATS) with saline wash prior to reinfusion in cardiac surgery. MEASUREMENTS AND MAIN RESULTS: The salvaged blood volume ranged from 36 to 2,795 ml, with a mean of 321 +/- 222 ml (SD). Eighteen percent of patients did not receive any homologous blood products during their hospitalization. Patients who received only salvaged autologous transfusion were younger, had higher preoperative hemoglobin and hematocrit values, had a larger body surface area, and had shorter surgeries compared with patients who received only homologous blood or both autologous and homologous blood. More blood products were given to patients who received salvaged autologous blood compared with those who did not. Patients who underwent normovolemic hemodilution prior to extracorporeal circulation with subsequent reinfusion received significantly fewer blood products. Ten preoperative and four intraoperative variables significantly influenced the salvaged volume. Previous cardiac surgery was the most significant preoperative variable, and repair of ventricular septal defect produced by myocardial ischemia was the most significant intraoperative variable. CONCLUSION: Considering the average salvaged volume and its current autologous transfusion-related expense, autologous blood salvage is potentially an economic benefit. Perioperative blood conservation requires a considerable commitment from surgeons, anesthesiologists, perfusionists, and intensive care physicians to be effective.     

Determinants of homologous blood usage utilizing autologous platelet-rich plasma in cardiac operations

The present study evaluated (1) the influence of the collection of autologous platelet-rich plasma intraoperatively in addition to intraoperative autotransfusion on homologous blood usage and bleeding in cardiac operations; (2) the influence of age, sex, body surface area, type of operation, and reoperations on homologous blood usage and bleeding in cardiac operations utilizing intraoperative autotransfusion and autologous platelet-rich plasma collected intraoperatively; and (3) the influence of the preoperative administration of aspirin, Persantine (dipyridamole), heparin sodium, thrombolytic agents, Coumadin (crystalline warfarin sodium), and nonsteroid, antiinflammatory drugs on homologous blood usage and bleeding in cardiac operations utilizing intraoperative autotransfusion and autologous platelet-rich plasma collected intraoperatively. The results demonstrated a decrease in homologous blood use and bleeding when autologous platelet-rich plasma is collected in addition to the use of intraoperative autotransfusion. All of the patient and procedural variables influenced homologous blood usage and bleeding to some extent. Only the thrombolytic agents affected blood usage by increasing homologous plasma usage. All other drugs evaluated did not influence blood utilization or the amount of bleeding intraoperatively or postoperatively.     

Safety and efficacy of autologous blood donation before elective off-pump coronary artery bypass grafting

BACKGROUND: Preoperative autologous blood donation reduces exposure to homologous blood transfusions in cardiac surgery. The purpose of this study was to ascertain, how much volume of predonated autologous blood needed to avoid of homologous blood transfusion in scheduled off-pump coronary artery bypass grafting (OPCAB). METHOD: Fifty patients underwent scheduled OPCAB. These patients donated 400 ml (group A, n = 30) or 800 ml (group B, n = 20) of autologous blood before operation. These patients donated at a rate of 400 ml per week. All patients were given an equal volume of saline solution at the time of autologous donation. RESULT: There were no significant differences mean age, mean body weight, mean preoperative hematocrit values, mean graft number or mean volume of intraoperative blood loss between groups A and B. There was significant difference the mean postoperative day-7 hematocrit value (33.4 +/- 1.5% vs 38.7 +/- 1.5%, p < 0.05). The rates of avoiding homologous blood transfusion were 63.3% in group A and 100% in group B (p < 0.05). CONCLUSIONS: Autologous blood transfusion was effective for reducing the homologous blood requirement. We believe that 800 ml predonation is sufficient to avoid homologous blood transfusion in scheduled OPCAB, further patients with cardiovascular disease including severe coronary artery should be donated with the administration of saline.     

Autologous transfusions for orthopaedic procedures at a children's hospital.

We conducted a critical review of the use of autologous transfusions in orthopaedics at a tertiary-care children's hospital. The cases of 198 children who deposited blood before an orthopaedic operation were analyzed. There were 175 children who were enrolled in the program of preoperative deposit of autologous blood who later needed transfusion of blood; 73 per cent of them received only autologous blood. Seventy patients also had intraoperative salvage. We were unable to document a proved benefit of intraoperative salvage of blood in this group of patients. Forty patients had some difficulty donating autologous blood preoperatively, but these problems were rarely serious. Major human errors occurred in thirteen patients and resulted in some patients receiving homologous transfusions while autologous blood components were still available. Fifty-five (40 per cent) of all of the transfusions were administered in clinical circumstances that failed to meet generally accepted criteria for transfusion, and fifty-four (38 per cent) of the postoperative transfusions also failed to meet these criteria. This was true of the homologous transfusions in the study as well. Although an autologous blood transfusion is a generally safe procedure, it is not without risk, and human errors can occur. In light of the potential complications, surgeons should adhere to the standard indications for transfusion when administering autologous blood.     

Experience of predeposit autologous blood transfusion and medication of recombinant human erythropoietin in pediatric open heart surgery]

To avoid using the homologous blood, 11 children between the age of 5 and 15 years donated autologous blood of 10 ml/kg of body weight (upper limit 400 ml) once a week for two weeks prior to elective open heart surgery. Five of 11 children received erythropoietin (100 U/kg of body weight) intravenously three times a week for two weeks. Only one patient experienced a mild donor reaction but no adverse effects occurred in erythropoietin therapy. In all the patients cardiac operations were able to be completed without homologous blood transfusion. Patients treated with erythropoietin were not anemic despite of preoperative donation although without erythropoietin therapy patients were mildly anemic. Our experience documents safety and effectiveness of predeposit autologous blood transfusion and erythropoietin therapy in pediatrics.     

Recombinant erythropoietin in autologous blood donation

As a result of the AIDS crisis, public and physician pressure have increased the utilization of autologous blood products. Attitudes about homologous blood transfusion, however, have changed dramatically in recent years. A large segment of the population undergoing elective surgery is elderly and therefore has a significant incidence of cardiovascular disease and a slow response of the erythropoietic system when acute anemia occurs. However, preoperative autologous blood donation programs require 2-5 weeks to complete; the average yield is only 2.2 units per patient. As a consequence, autologous predonation is underused and homologous transfusion cannot be completely avoided in all patients. For several years recombinant human erythropoietin (rHuEPO) has been available and has been successfully used in the treatment of patients with renal anemia. This study evaluated the effect of r-HuEPO on patients with preoperative autologous blood collection. METHODS. Ten patients of both sexes scheduled for hip arthroplasty underwent a preoperative autologous program. During a period of 23 days prior to surgery autologous blood donation was performed with 7.5 ml/kg withdrawal on four occasions, the last one 5 days prior to surgery. Five patients were randomly treated with subcutaneous injections of rHuEPO (Erypo, Cilag GmbH, Sulzbach; Distributor: Fresenius AG, Oberursel, FRG) 200 IU/kg seven times, starting 3 days after the first blood withdrawal. All patients (n = 10) received oral iron therapy with iron sulphate 304 mg/die (= 100 mg iron/die). Patients with hypertension or recent myocardial infarction were excluded from the study. The hemoglobin level before donation had to be at least 11.0 g/dl. On each study day, a complete blood count and platelets, differential, and reticulocyte count were determined by standard methods as were transferrin, ferritin, and total iron-binding capacity. Blood loss and blood consumption during and after the operation were registered. The indication for blood transfusion (autologous/homologous) was based on hemoglobin values, which were not acceptable below 8.5 g/dl. RESULTS. No side effects of rHuEPO treatment were observed. Blood loss ranged from 650 to 1100 ml intraoperatively and 400 to 950 ml postoperatively with no differences between the groups. Patients with rHuEPO had no autologous red cell concentrates (aRCC) during the operation; two of them had two units of aRCC on the 2nd postoperative day. Two of the patients in the control group had intraoperative blood transfusions (2 and 3 units aRCC, respectively); all patients in this group were transfused postoperatively: 12 of the 20 units collected were utilized. At the onset of the operation the mean hemoglobin value in patients with rHuEPO was 13.5 +/- 0.4 g/dl compared to 11.3 +/- 0.3 g/dl in the controls. Reticulocytes increased significantly during the investigation period. On the 2nd, 3rd, and 4th days of autologous blood collection and before the onset of surgery, the number of reticulocytes was significantly greater in rHuEPO patients than in the controls. Further laboratory variables such as transferrin, ferritin, and total iron-binding capacity did not change significantly during the investigation period; there were no significant differences between the two groups. DISCUSSION. The results of the present study show that rHuEPO leads to an increase in reticulocytes with maintenance of hemoglobin levels during the phlebotomy program. As a consequence, patients with anemia and particular contraindications to homologous blood derivatives (irregular antibodies, Jehovah's Witnesses) may be able to undergo major surgery successfully. The possibility of shortening the intervals between phlebotomies would seem to be of major advantage; our data also suggest that an aggressive autologous blood collection program would increase yields over present programs. In our institute a minimum hemoglobin level of 11.5 g/dl is accepted for autologous donation.(ABSTRACT TRUNCATED AT 400 WORDS)     

Autologous blood transfusion with erythropoietin in heart surgery in an anemic patient]

A 78-year-old woman was diagnosed as having three-vessel coronary artery disease. A coronary artery bypass operation with autologous blood transfusion was indicated because of the irregular antibody and because homologous blood transfusion would lead to hemolytic complications. Since she had anemia (hemoglobin level, 10.7 g/dl) and autologous blood could not be collected, recombinant human erythropoietin (rHuEPO) and iron preparations were administered intravenously every day. The hemoglobin level reached 12.1 g/dl two weeks after administration, and then autologous blood was donated. The first 1200 ml of blood was stored frozen, and the last 400 ml as liquid in consideration of the blood preservation period. Surgery was performed uneventfully after 8 weeks of rHuEPO administration. No homologous blood transfusion was required during and after surgery. By using rHuEPO, it is thus possible to perform heart surgery without homologous blood transfusion even in patients with anemia, for whom blood transfusions have been considered necessary.     

Safety and efficacy of autologous blood donation before elective aortic valve operation.

Although the use of preoperative autologous blood donations for patients undergoing elective cardiac operations has increased dramatically in recent years, patients awaiting elective aortic valve replacement have traditionally been denied access to preoperative autologous blood collection programs. We report our experience with 79 patients, each of whom donated 1 to 3 units of autologous blood before an aortic valve operation. All patients had serious aortic valve disease as evidenced by symptoms and preoperative catheterization data. The patients collectively made 129 blood donations. One patient had a syncopal episode within 2 hours of donation and recovered without difficulty. Of the patients who gave autologous blood preoperatively, 68% avoided any homologous blood donor exposure during their subsequent hospitalization for aortic valve replacement. In contrast, in a group of 298 patients who did not give autologous blood preoperatively, only 31% avoided homologous blood exposure during aortic valve replacement (p < 0.0001). Our experience suggests that preoperative autologous blood donation by patients awaiting elective aortic valve replacement is both safe and effective. Patients with aortic valve disease should not be routinely excluded from preoperative blood services.     

Preoperative autologous blood donation with cardiac surgery

BACKGROUND: Preoperative autologous blood donation is commonly used to reduce exposure to homologous blood transfusions among patients undergoing elective cardiac surgery. The purpose of this study was to ascertain how much volume of predonated autologous blood need to avoid of homologous blood transfusion in cardiac procedure. METHODS: One hundred twenty-eight patients underwent scheduled cardiac procedure between January 1998 and December 1999. Group 1: 400 ml predonated, operation without cardiopulmonary bypass (CPB) [n = 33], group 2: 800 ml predonated, operation without CPB (n = 23), group 3: 800 ml predonated, operation with CPB (n = 36), group 4: 1,200 ml predonated, operation with CPB (n = 36). Surgical procedures underwent only off-pump coronary artery bypass grafting (OPCAB) in groups 1 and 2. In groups 3 and 4 included coronary artery bypass grafting (CABG), valve replacement, CABG + valve replacement and atrial septal defect repair. RESULTS: There were no significant differences in mean body weight, mean preoperative hematocrit values or mean volume of intraoperative blood loss between groups 1 and 2. There were no significant differences in mean age, mean body weight, mean preoperative and postoperative day-7 hematocrit values, mean volume of intraoperative blood loss or mean CPB time between groups 3 and 4. The mean postoperative day-7 hematocrit value was significantly lower in group 1 than in group 2. Homologous blood transfusion was avoided in 63.6% of those with predonation of group 1 versus 100% at group 2 (p < 0.05), 86.1% at group 3 versus 94.4% at group 4 (p < 0.05). In group 3, all patients who underwent redo operation or CABG + valve replacement needed homologous blood transfusion. CONCLUSIONS: Autologous blood transfusion is effective for reducing the homologous blood requirement. It also seems that predonation of 800 ml may be sufficient to avoid homologous blood transfusion in cardiac surgery, however predonation of 1,200 ml is desirable in cases of redo operation or CABG + valve replacement.

Utilization and efficacy of autologous blood predeposit in radical prostatectomy with lymphadenectomy: implications for blood conservation and physician education programs.

Autologous blood predeposit is a widely used transfusion practice that has become a standard of care for elective surgery. Despite the support for this practice there are unanswered questions in the usage and efficacy of autologous blood programs. This study is a prospective analysis of 52 consecutively audited urologic patients undergoing elective, radical prostatectomy with lymphadenectomy in which all 52 patients predonated autologous blood. Preoperative blood donation, blood transfused, surgical blood lost, and the "transfusion trigger" were evaluated for each of these patients. We conclude (1) the rate of homologous blood exposure (15%) despite preoperative autologous blood donation in every patient indicates a need for innovative blood conservation strategies to minimize homologous blood transfusion in this surgical group. (2) Unnecessary autologous transfusions could be identified in 8 (15%) of 52 patients, all of which were single unit autologous blood transfusions. (3) Physician education programs that emphasize increased procurement of autologous blood along with more conservative transfusion of this blood are needed to avoid necessary homologous blood and unnecessary autologous blood transfusion.     

自体血小板分离联合术中自体血回输对骨科手术患者凝血功能的影响作用

目的观察术前自体血小板分离联合术中自体血回输对骨科手术患者凝血功能的影响作用。方法60例骨科择期手术患者（预计出血量〉1000ml,ASAⅠ～Ⅱ级）,随机分为3组,每组20例患者。Ⅰ组采用术前自体血小板分离联合术中自体血回输,Ⅱ组采用单纯术中自体血回输,Ⅲ组不进行任何血液保护措施。各组分别于麻醉前、血小板分离后10min、保存的血小板或自体血回输前10min、回输后10min、术后24h、术后48h检测相应时点的血红蛋白水平、凝血功能、血小板水平和聚集功能、术中术后出血量及异体输血情况。结果三组的一般资料、术中出血量、术中术后的血红蛋白水平比较未见明显差异。与Ⅰ组相比,Ⅱ、Ⅲ组术后24h和术后48h的血小板水平和聚集功能明显降低（P〈0．05）,术后出血量及异体输血率则明显增高（P〈0．01）。结论术前自体血小板分离联合术中自体血回输可明显改善骨科手术患者的凝血功能,并有效降低术后出血量和异体血的输注。     

Intraoperative autologous transfusion in children undergoing spinal surgery

An intraoperative autologous transfusion program was used in conjunction with preoperative phlebotomy in 25 children undergoing elective spinal surgery. Operative red blood cells, 10,000 ml, with an average hematocrit of 55%, as well as 7,300 ml of preoperative phlebotomy blood were returned to the patients. No complications were noted. The complete blood count on discharge was satisfactory, and the clotting parameters were unchanged. The results of this study show that intraoperative autologous transfusion with preoperative phlebotomy is safe, easy to perform, and cost-effective in children undergoing elective spinal surgery. The risks of homologous blood transfusions were eliminated.     

Preoperative hemodilution to reduce homologous blood transfusion--effects on hemodynamics and oxygen flux]

Many problems arise from homologous blood transfusion in operative patients. Preoperative collection of blood with hemodilution is a simple method to allow autologous blood transfusion. Sixty patients who received gynecological operations were divided into three groups. Patients in the first and second groups underwent preoperative blood collection and hemodilution, and collected blood was transfused during operation when bleeding volume had exceeded prefixed value. The volume and speed of blood collection were 20 ml.kg-1 and 30 minutes in the first group, and 20 ml.kg-1 and 15 minutes in the second group. After the collection of blood, HES solution was infused to maintain blood volume. The patients in the third group were transfused with homologous blood as controls. The blood pressure, heart rate, cardiac index and oxygen flux were maintained well in the first group after collection of blood and hemodilution. The hemoglobin concentration was kept at 10 g.dl-1 when the operation was terminated with a mean bleeding volume of 1,014 ml. The results suggest that the method of preoperative blood collection and hemodilution followed by autologous blood transfusion is a promising technic to reduce the amount of homologous blood transfusion in operative patients.     

Blood saving in pediatric orthopedics. A study of 145 posterior vertebral arthrodesis

The authors review 145 operations utilizing the Cotrel-Dubousset technique for scoliosis and/or cyphosis over a period of 4 years. From 1985 to 1989, the number of patients who received no homologous blood rose from 0% to 85% for the totality of cases. Inversely, the average quantity per patient of homologous blood used for transfusion decreased from 3,564 ml to 194 ml, ie. -94%. Among the 145 operated patients, 47 (33%) have never received a transfusion, whether or not an autotransfusion procedure was planned; out of the 41 children prepared with preoperative autologous sampling, 39 (97%) received no homologous blood. The authors study the various means used to achieve these results in a particularly hemorrhagic surgical procedure: low blood pressure techniques, intraoperative installation and warming, peroperative recovery of blood, decrease in duration and bleeding using natural coral to avoid removing an iliac bone graft, study of evoked potentials to prevent intraoperative awakening, better postoperative control of bleeding by means of an original drain tube. As a conclusion, they state that, owing to better coordination between surgery, anesthesiology and blood biology, such definite progress may be extended to other operations in future.     

Combination of acute normovolemic hemodilution technique with preoperative autologous blood donation prevented allogeneic blood transfusion against 4000 g surgical blood loss in a patient undergoing left partial nephrectomy

A 41-year-old male patient with well-controlled hypertension underwent a partial nephrectomy under total intravenous anesthesia with propofol, fentanyl and ketamine. To avoid allogeneic blood transfusion, preoperative autologous blood donation (400 g) a week before the surgery and acute normovolemic hemodilution (800 g) after induction of anesthesia were performed. As surgical blood loss was more than 4000 g, blood hemoglobin (Hb) level decreased to 6.4 g.dl-1. However, as intraoperative hemodynamics was relatively stable with no ischemic changes in ECG and arterial blood gas analysis did not show metabolic acidosis, autologous blood transfusion was withheld till hemostasis had been done. After returning the autologous blood, Hb increased to 9.4 g.dl-1. On the 2nd postoperative day, Hb decreased to 7.6 g.dl-1. As the patient's vital signs did not show any severe complications, blood transfusion was not performed. Then, the Hb level increased gradually to 13.9 g.dl-1, 3 month later without allogenic blood transfusion. In addition, any postoperative complications by low Hb level were not recognized so far. This case suggests that combination of autologous transfusion techniques may be effective to avoid allogeneic blood transfusion even against massive hemorrhage. However, to avoid disadvantage of these technique, we should always evaluate preoperative patient conditions.     

Beneficial effect of acute normovolemic hemodilution in cardiovascular surgery

OBJECTIVE: The efficacy of acute normovolemic hemodilution (ANH) in avoiding homologous blood transfusion (HBT) during cardiovascular surgery remains controversial. Our objective was to evaluate the impact of ANH on blood transfusion requirements during open cardiovascular surgery using cardiopulmonary bypass (CPB). METHODS: We retrospectively reviewed 243 patients who had undergone open cardiac or thoracic aortic surgery using CPB between September 2001 and July 2003 in our department. ANH was performed when the hematocrit was over 35% and the patient was hemodynamically stable. Risk factors were selected in accordance with the Japanese Adult Cardiovascular Surgery Database and analyzed to determine their effect on perioperative HBT requirement. RESULTS: Of the 243 patients, 64 (26%) underwent preoperative autologous blood donation and 62 (26%) ANH. HBT was required in 62% of patients (150/243) overall, in 32% (20/62) of ANH patients, and in 76% (130/171) of non-ANH patients. Multivariate stepwise logistic regression analysis revealed that preoperative or pre-donation hemoglobin value (p < 0.001), duration of surgery (p = 0.001), intraoperative minimum rectal temperature (p = 0.001), age (p = 0.002), need for emergency surgery (p = 0.003), amount of ANH (p = 0.018), blood loss (p = 0.033) and amount of preoperative autologous blood donation (p = 0.042) were independent predictors of the need for perioperative HBT. CONCLUSIONS: Our data showed that open cardiovascular surgery using CPB continues to pose a high risk of HBT, but that ANH is an effective means of reducing this risk in those patients undergoing these operations.     

Measures for reducing the use of homologous blood. Effects on blood coagulation during total endoprosthesis]

The influence of two different methods of autologous transfusion, preoperative donor plasmapheresis (Abbott Autotrans) and postoperative autotransfusion (intraoperative blood salvage, Dideco Autotrans), on the intravascular hemostatic system was investigated. Forty-two patients undergoing total hip surgery and preoperative donor plasmapheresis were prospectively randomized into three groups. For substitution of blood loss, patients in group 1 (control group, n = 12) received in addition to cristalloids and colloids only homologous blood, group 2 (n = 14) autologous blood, and group 3 (n = 16) additionally intra- and postoperative autologous fresh frozen plasma (FFP). The investigation included blood parameters (hemoglobin, hematocrit, thrombocytes), clotting status (prothrombin time, plasma thromboplastin time, thrombin time, fibrinogen, plasminogen, and antithrombin III), and immunological methods such as fibrinopeptide A (FPA), thrombin-antithrombin III (TAT), and protein C. No significant difference was found with respect to total amount of infusion, intraoperative blood loss, autologous transfusion, and blood parameters. Excellent quality of the autologous FFP was demonstrated by investigation of the specimens before administration. The autologous packed red cells showed high levels of TAT and FPA as an indicator of thrombin generation. Their administration caused a significant increase in TAT and FPA levels in groups 2 and 3 compared to group 1.(ABSTRACT TRUNCATED AT 250 WORDS)     

Autologous blood transfusion in revision hip arthroplasty. A prospective, controlled study of 30 patients.

In a prospective, randomized study of the efficacy and effects of autologous blood transfusion in revision hip arthroplasty, 30 patients were randomly allocated into two groups. The Control Group received homologous blood transfusion. The Study Group deposited 2-3 units of blood preoperatively, intraoperative blood salvage was used, and no homologous blood was transfused intraoperatively. There was a smaller postoperative blood loss in the Study Group. The preoperative hemoglobin values were lower in the Study Group, but one week postoperatively they were higher than in the Control Group. The decrease in the values of AT III and protein C was lower in the Study Group. The combination of preoperative blood donation and intraoperative blood salvage reduced blood loss and homologous blood transfusion in revision hip arthroplasty.
