The variation of perioperative and postoperative hemochromocytometric parameters in patients who have undergone suprapubic prostatectomy and TURP due to prostatic hypertrophy, according to the type of transfusion (autotransfused and non-autotransfused patients: patients with both autologous and homologous transfusion; patients with homologous transfusion only), have been examined by the authors in their survey. Autotransfusion maintained hemochromocytometric parameters within safety limits without any homologous transfusion thus confirming literature data. In all the groups, a remarkable decrease in hematocrit, hemoglobin and red cells has been reported. No remarkable differences between autotransfused patients and patients without transfusion have been reported. Differences are significant in the group of patients with homologous transfusion. In autotransfused patients decrease in platelets is notable. In this way, hematic viscosity and relevant decrease of the thrombo-embolic risk is demonstrated.

The variation in ATIII activity in the post prostatectomy period is examined by the Authors and is correlated with pulmonary embolism. Type of anaesthesia, blood transfusion and modality of blood transfusion (autotransfusion V/S homologous transfusion) were the parameters considered. In the post surgery period, the ATIII level decreases and afterwards slowly recovers. ATIII variations were similar in both auto transfused and non-transfused patients. The ATIII level decreased more in transfused patients than in those auto or not transfused. Other factors lowering the ATIII level were suprapubic prostatectomy and loco-regional anaesthesia; TURP or general anaesthesia were less influential. In the patients with pulmonary embolism ATIII activity decreased to below 70%. The Authors correlate these data with the risk of embolism.
