[Preoperative autologous blood donation and transfusion in gynecology].

BACKGROUND: Autologous transfusions reduce the risk of alloimmune and infectious complications of allogenic blood transfusions. We have evaluated preoperative autologous blood donation practice in relation to patients characteristics and surgical technique. METHODS: In the Obstetrics and Gynecology Department of Genoa University, we enrolled 462 patients in an autologous transfusion program during 1997. We did not analyze 105 patients who underwent minor surgery. Patients with hemoglobin lower than 11 g/dl or with other risks related to autotransfusion have been excluded; 284 (79.5%) patients have been able to make preoperative autologous blood donations. Patients who did not undergo predeposit have utilised type screen or cross reaction for a possible who did eterologous transfusion. We have analysed the two groups of patients for kind of pathology, for number of heterologous blood units used, for number of transfused patients and we have considered the mean of the units received by each of them. RESULTS: 44 of the 284 predeposited blood units were reinfused while 10 patients, who did not undergo predeposit, were transfused. Heterologous transfusion was done in 1.06% of the cases that underwent predeposit. Oncologic patients underwent predeposit in 83% of the cases. CONCLUSIONS: We have concluded that autologous blood donation reduces the risk of allogenic blood transfusion especially in oncologic surgery.
