Comparison of hemodynamic effect between the spinal anesthesia and saddle block during transurethral resection of the prostate

Background: The best technique for transurethral resection of prostate (TURP) is regional anesthesia. The hypotension is the major complication following spinal anesthesia. The hemodynamic changes is less with saddle block than spinal block. Aim and Objective: To compare hemodynamic effect between the spinal block and saddle block in TURP. Patients and methods: 50 patients between 50-70 years old ASA I – II prepared for TURP, divided randomly in two groups 25 pt. in each group. Group A received spinal 10 mg of hyperbaric bupivacaine (2 ml of 0.5%), were group B received saddle block 10 mg of hyperbaric bupivacaine (2 ml of 0.5%). The blood pressure, oxygen saturation, heart rate measured and recorded subsequently. The hypotension treated by 100 mcg bolus of phenylephrine. Results: In our study there was statically significant difference (p < 0.05) between group A which received spinal anesthesia and group B which received saddle block in hemodynamic effect. In which the incidence of hypotension and vasopressor requirement more in group A. Conclusion: Under saddle block the TURP can safely performed with low risk of hypotension and less requirement of vasopressor.
