[Autologous blood transfusion].

Autologous blood transfusion techniques are the principal means of reducing allogeneic blood exposure. Those techniques were developed in order to prevent the risk of contamination by viruses, mainly HVB, HCV and HIV. However that risk has become so small that all studies show an exorbitant cost/efficiency ratio. Autologous blood transfusion would therefore be of no interest in terms of public health but a recent experimental study suggested a possible transmission of the BSE agent through blood. Until the matter is settled, the precaution principle means we should prefer alternative techniques to allogeneic blood whenever possible, hence a renewed interest in autologous transfusion.

Blood Transfusion, Autologous↗

Autologous blood transfusion.

Autologous blood transfusion is a procedure in which blood is removed from a donor and returned to his circulation at some later time. Autologous transfusion can be performed in three ways: (1) preoperative blood collection, storage, and retransfusion during surgery; (2) immediate preoperative phlebotomy with subsequent artificial hemodilution and later return of the phlebotomized blood; and (3) intraoperative blood salvage and retransfusion. All three methods of autologous transfusion offer a potentially superior method of blood transfusion which eliminates many of the problems and complications associated with the banking and administration of homologous donor blood.

Blood Preservation↗

Autologous blood transfusion.

Autologous blood transfusion is emerging as a popular option in patients undergoing elective procedures. Predeposit and perioperative autotransfusion, the two major types of autologous transfusion, can be performed safely in a wide variety of conditions and in patients of all ages. We discuss the risks and benefits and outline the minimal requirements of donor-patients. Autologous blood transfusion is a safe and effective method of providing blood products. It is the safest transfusion practice.

Blood Transfusion, Autologous↗

Autologous blood transfusion.

Autologous blood transfusion is an endorsed blood conservation strategy that has become widely practiced in elective surgical procedures. We review ten years' experience in this arena, along with emerging strategies designed to continue to minimize allogeneic blood exposure but reduce the costs associated with autologous blood procurement. We conclude that point-of-care autologous blood procurement (acute normovolemic hemodilution and intraoperative autologous blood salvage) can replace the predonation of autologous blood in surgical patients when transfusion medicine specialists, anesthesiologists, and surgeons develop a prospective, comprehensive approach to blood conservation.

Nursing management of autologous blood transfusion.

Autologous blood transfusion (ATS) is now a common procedure used in a variety of health care settings. ATS can occur during several stages in a patient's care and may be administered through a variety of methods. This article discusses the development of ATS, its advantages and disadvantages, issues surrounding its use, and the types of ATS currently in use. Examples of several methods and nursing considerations for management of ATS are presented.

Autologous blood transfusion.

Autologous blood transfusion--transfusion to the patient of his or her own blood--is of increasing importance in transfusion practice. There are three main techniques: pre-deposit, in which patients donate blood over a period of time in preparation for elective surgery; preoperative isovolaemic haemodilution, in which blood is removed in theatre immediately preoperatively and volume replacement is given, the blood being reinfused postoperatively; and salvage transfusion - the harvesting of blood shed at surgery or in similar circumstances, which is reinfused immediately or after concentration and purification. All these techniques can play a part in rendering transfusion safer and in economising on scarce supplies of donor blood.

Effect of substituting allogenic blood transfusion with autologous blood transfusion on outcomes after radical oesophagectomy for cancer.

BACKGROUND: The oncologic benefit of avoiding allogenic blood transfusion in oesophageal cancer resection has not been studied. METHODS: The medical records of 68 patients (Auto group) who underwent a potentially curative oesophageal cancer resection without allogenic blood transfusion from 1996 to 1999 receiving 800 g of autologous blood donated preoperatively, and 97 patients (Allo group) who underwent the same operation with allogenic blood transfusion from 1990 to 1995 were compared. RESULTS: There were no differences in age, gender, stage of disease, number of retrieved nodes, or perioperative hemoglobin concentration between the two groups. The survival of the 45 patients with nodal involvement in the Auto group was better than that of the 59 patients in the Allo group (p=0.0435), and the survival of the 35 patients with T3 or T4 lesions in the Auto group was better than that of the 61 patients in the Allo group (p=0.0408). According to logistic regression analysis, allogenic blood transfusion correlated with tumour recurrence in patients with either nodal involvement or a T3-4 lesion. The natural killer cell activity remained higher in the Auto group than in the Allo group (p<0.05). CONCLUSION: Avoidance of allogenic blood transfusion favorably effected the survival of patients with oesophageal cancer at risk for recurrence.

Autologous blood transfusion today.

Autologous blood transfusion--the transfusion to a patient of his or her own blood--is increasingly being recognised as a useful adjunct to traditional transfusion practice. The reasons include fears of disease transmission, the potential adverse effects on the recipient's immune system of transfused donor blood, and logistical factors. The three main techniques of autologous transfusion are: (i) pre-deposit, in which patients donate blood over a period of time in preparation for elective surgery; (ii) pre-operative isovolaemic haemodilution, in which blood is removed immediately before surgery and volume replacement is given, the blood being reinfused post-operatively; and (iii) salvage transfusion--the collection of blood shed at surgery or in similar circumstances, which is reinfused immediately or after concentration and purification. All three techniques can help to improve the safety of transfusion and economise on scarce supplies of donor blood.

[The use of the autologous blood transfusion to the respiratory surgery: autologous blood transfusion or no-blood transfusion surgery?].

We could report the effect of the autologous blood transfusion to the lobectomy, by comparison with no-blood transfusion group and MAP-red cell concentrate transfused group (MAP group). Autologous blood which was stored three days before an operation and preserved at 4 degrees C kept 89.9 +/- 11.7% of the number of erythrocyte and 59.6 +/- 23.4% of platelet. Autologous blood transfusion group and MAP group showed significantly more than no-blood transfusion group on the number of erythrocyte at the time of discharge. These facts suggest that the autologous blood has an ability of coagulation. We concluded that on lobectomy autologous blood transfusion was better than MAP-red cell concentrate transfusion in point of protection from disease transmission and better than no-blood transfusion in point of post-operative recovery.

Cost analysis of autologous blood transfusion, using cell salvage, compared with allogeneic blood transfusion.

Autologous transfusion is an option infrequently used in the UK, partly because the direct costs are greater than for allogeneic transfusion. An analysis of the cost consequences of substituting autologous for allogeneic blood, by using cell salvage, was undertaken from a hospital perspective. Direct costs were estimated for two different cell salvage devices and sensitivity analysis performed on the key variables. Allogeneic transfusion may be associated with increased rates of postoperative infection due immunomodulation and immunosuppression. As a result, one of the short-term benefits of autologous transfusion is a possible reduction in length of hospital stay. This was the most important variable affecting the cost of autologous transfusion. Cost equivalence for autologous and allogeneic blood was reached at reductions in hospital stay of between 0.3 and 2 days across a range of variables. Reductions in length of hospital stay of this magnitude have been reported in several small studies. The results of our cost analysis suggest that autologous transfusion should not be rejected on the grounds of cost and we recommend a large-scale randomized controlled trial of autologous vs. allogeneic transfusion.

Evaluation of awareness and utilization of an autologous blood transfusion programme.

Autologous blood transfusion (ABT) has an important role in transfusion practice in the developing world due to increasing incidence of HIV and hepatitis C virus infection. Our study was done to evaluate the level of awareness and utilization of an autologous blood transfusion programme in a teaching hospital in Delhi. We assessed the level of awareness of preoperative ABT amongst treating physicians from different specialties in a teaching hospital through an anonymous questionnaire. The utilization of this methodology in transfusion practice was estimated from records of the Blood Transfusion Service. Of the 150 doctors contacted 96 (64%) responded. Although 67.7% of them were aware of the technique and its advantages, only 21.8% used it for the patients under their care. In the preceding 24 months 133 (1.1%) of 12,090 blood collections in the transfusion service were from autologous donor-patients. Only one unit of blood was collected from each patient, although 41.8% of them received > or = 2 units of blood. Of the 11,123 patients transfused, 55 (0.49%) received the ABT. Thus only 55 (41.3%) of 133 total ABT collections were utilized. The study highlights that there is a general lack of awareness about ABT amongst physicians. This transfusion practice is rarely and inadequately used. The study was repeated the following year after an intensive intervention strategy was adopted. The results show a trend towards improvement in the practice of ABT. This study emphasizes the need for proper organization, planning and communication between clinicians and blood transfusion personnel for effective implementation of an ABT programme, especially in countries with a high incidence of transfusion-transmitted infections and acute shortages of blood for transfusion.

[Preoperative use of erythropoietin (rH-EPO) and determination of optimal doses in patients with benign prostatic hypertrophy for future autologous blood transfusion].

BACKGROUND: Recently, autologous blood transfusion has been widely endorsed, because of the adverse effects attributed to homologous blood transfusion. We found that the administration of recombinant human erythropoietin (rH-EPO) permitted the preoperative collection of an adequate volume of autologous blood in a short period of time. This reduced or eliminated the need for homologous blood transfusion. METHODS: To determine optimal dosage of rH-EPO, I conducted a randomized, controlled trial in 86 patients with benign prostatic hypertrophy (BPH) scheduled for transurethral resection of the prostate (TUR-P). The patients from whom approximately 10% of their total blood volume was removed, received six different doses of rH-EPO either intravenously or subctaneously. All patients received iron sulfate 100 mg orally once a day during the study. RESULTS: I found that 9,000 IU of rH-EPO given intravenously daily or 10,500 IU of rH-EPO injected subcutaneously every third day for a week were optimal dosages. These schedules ennabled us to withdraw approximately 400 ml of blood prior to operation without adverse effects. CONCLUSION: I conclude that the efficacy of rH-EPO is greater when administered subcutaneously rather than intravenously. It is clear that rH-EPO increases the ability of patients about to undergo selective surgery to donate greater amounts of blood for future autologous transfusion.

[Autologous blood transfusion: results with routine use of autologous blood transfusion, normovolemic hemodilution and postoperative retransfusion of drainage blood salvaged with the Solcotrans system].

BACKGROUND: Although the medical advantages of autologous blood transfusion are undisputed today, it has been established only in a few hospitals. At our hospital we have employed infusion of previously stored autologous blood and normovolemic hemodilution routinely in all patients undergoing major orthopedic surgery since June 1, 1986. QUESTION: In this study the efficacy of additionally infusing salvaged drainage blood postoperatively in reducing the need for homologous blood transfusion was examined. METHOD: From June 1, 1990 through December 30, 1993 the effectiveness of autotransfusion techniques with the additional use of postoperative infusion of salvaged blood was studied in 318 patients. RESULTS: Preexisting anemia with hemoglobin value of less than 11 g/dl proved to be the only contra-indication for autologous blood transfusions and was found in 8 (2.5%) of our patients. These patients were not eligible for the autologous blood program. The 310 remaining patients were all given their previously stored autologous blood with hemodilution. In addition, 261 of these patients (84%) were also given salvaged drainage blood postoperatively using the solcotrans system or solcotrans-plus-orthopedic system. Of the total 310 patients, 218 (70.3%) did well without homologous blood. This was also true for 206 (78.9%) of the patients treated with all 3 autotransfusion procedures. No complications implicating the autotransfusion techniques were encountered. In addition, the method described and as employed in our hospital led to a cost reduction of about 40% compared to homologous transfusions. DISCUSSION AND CONCLUSION: The efficiency of autologous blood transfusions and hemodilution in reducing the need for homologous blood at our hospital, as previously described, could be increased by 22% using the solcotrans system. The advanced age of our patients (average 73 years) and the number of preexisting, in part considerable, medical problems permit the conclusion that these autotransfusion techniques are quite well tolerated. The contraindications could be reduced to a few exceptions. The logistics necessary to carry out these procedures are simple and can be achieved with a bit of will and effort in all hospitals including those of middle and small size.

Predeposit autologous blood transfusion in elderly patients undergoing transurethral resection of the prostate.

In order to reduce the rate of homologous blood transfusion, predeposit autologous blood transfusion has been introduced in 134 out of 266 patients undergoing transurethral resection of the prostate since February 1988. Nine (6.7%) out of 134 patients who deposited their own blood were also transfused with homologous blood. In contrast, the rate of homologous blood transfusion was 22.7% in 132 patients who did not deposit autologous blood. Overall homologous blood transfusion rate (14.7%) in the past 4.5 years has been much lower than in the previous 4 years (22.2% in 203 patients). In 6 patients in whom blood donation was performed concurrently with administration of recombinant human erythropoietin, decrease of haemoglobin level was significantly less than in those without rHuEPO. Predeposit autologous blood transfusion can reduce homologous blood transfusion rate. It is safe and easily performed, and more effective when combined with rHuEPO administration even in elderly patients undergoing TURP.

Laryngospasm after autologous blood transfusion.

Although perioperative autologous blood transfusions are associated with few side effects, transfusion reactions can occur and can be life-threatening. We report the occurrence of postoperative laryngospasm in a patient who underwent spinal anesthesia for hip surgery. The laryngospasm could not be attributed to any cause other than the autologous blood transfusion and recurred when the transfusion was restarted. Laryngospasm was successfully treated both times with positive pressure ventilation. Autologous transfusions can trigger febrile nonhemolytic transfusion reactions, which may result in airway compromise.
