Bupivacaine infiltration into the neurovascular bundle of the prostatic nerve does not improve postoperative pain or recovery following transvesical prostatectomy.
PURPOSE: We assessed the effect of intraoperative bupivacaine infiltration into the neurovascular bundle of the prostatic nerve on postoperative pain and patient outcome. MATERIALS AND METHODS: The study included 40 American Society of Anesthesiologists physical status I to III patients undergoing transvesical prostatectomy. Following surgical resection of the prostate the neurovascular bundle of the prostatic nerve was infiltrated with either 10 ml. bupivacaine 0.5% or saline. Postoperative pain intensity was assessed using a patient generated 100 mm. visual analog scale and a patient controlled analgesia device. Additional analgesic requirements, time to ambulation, length of hospitalization and return to normal activity were also recorded. RESULTS: There were no differences in visual analog scale for pain, patient controlled analgesia demands or actual morphine delivered. Similarly, saline versus bupivacaine infiltration did not influence ambulation time (21.3 +/- 2.7 versus 25.0 +/- 11.8 hours, respectively), length of hospitalization (7.06 +/- 0.8 versus 7.11 +/- 0.6 days, respectively), return to normal activity (14.4 +/- 8.8 versus 14.2 +/- 8.2 days, respectively) or patient satisfaction. On postoperative days 1 and 2 more patients in the saline treatment group requested additional oral analgesia compared to the bupivacaine treatment group. However, no statistical difference was demonstrated. CONCLUSIONS: Following transvesical prostatectomy, prostatic nerve blockade has no beneficial effects on postoperative pain or patient outcome.[1]References
