Background: Haemorrhage during prostatectomy is a significant cause of morbidity and mortality. Anaesthesia may influence the degree of haemorrhage during these operations. Aim: To assess the difference in blood loss between spinal and general anaesthesias. Material and Methods: Patients assessed fit for prostatectomy at the University of Port Harcourt Teaching Hospital (UPTH) and some private hospitals were alternately allocated to either general or spinal anaesthesia for the procedure. All the surgeons were based in the Urology Unit of UPTH. The intra-operative blood loss for each patient was assessed by the gravimetric method and was compared under spinal anaesthesia (SA) and general anaesthesia (GA). The blood pressure, ECG and Oxygen saturation were monitored. The enucleated prostate glands were weighed. Results: Eighty consecutive patients in two groups of forty each were included in the study. There was no conversion from one form of anaesthesia to another. The mean blood loss with GA (Group A) was 829 ± 15 ml (range 450-1100 ml) while that for SA (Group B) was 526 ± 25 ml (range 300- 700 ml). Using the student t-test, the difference between the two groups was statistically significant (P<0.05). The study showed a 36.6% intraoperative blood loss under SA less than that from GA. The mean weight of prostate in Group A was 72.4g ± 8.2 (mean ± SD) while it was 84.6 g ± 7.5 (mean ± SD) in Group B. There was no correlation between blood loss and the weight of the gland removed. Conclusion: The anaesthetic technique is of relevance in reducing intraopera five blood loss. Reduced blood loss will consequently reduce the risks of allogeneic blood transfusion.
