PURPOSE:Radical prostatectomy is associated with substantial blood loss frequently requiring allogeneic blood transfusion. We investigated the efficacy of deliberate hypotension using combined epidural/general anesthesia in reducing allogeneic transfusion requirements in patients undergoing radical prostatectomy. METHODS: In a prospective, randomized, single-blind trial, 102 patients undergoing radical prostatectomy were allocated to either an epidural group (n = 51) or a control group (n = 51). In the epidural group, deliberate hypotension was achieved with a target mean arterial pressure of 55-60 mmHg. The trigger for allogeneic blood transfusion in both groups was a hematocrit value < 0.25. RESULTS:Operative blood loss in the epidural group was significantly less than that in the control group (955 +/- 517 mL vs 1477 +/- 823 mL respectively, P < 0.001). The percentage of patients who reached the threshold trigger for allogenic transfusion was significantly less in the epidural group (8% vs 26%, respectively, P = 0.019) and the number of patients who were actually transfused during hospitalization was also significantly less (P = 0.028). There were no serious adverse events in either group during the study. CONCLUSION: Controlled hypotension using a combined epidural/ general anesthetic technique is associated with significantly less blood loss, and a reduction in the use of allogeneic blood in patients undergoing radical prostatectomy compared to general anesthesia alone.
