PURPOSE: We report our experience of paravertebral block (PVB) on analgesic requirements and dynamic pain in patients presenting for hand-assisted laparoscopic nephrectomy (HALN) and compare our results with conventional opioid therapy. PATIENTS AND METHODS: From October 2006 to May 2008, 30 patients (male:female ratio, 17:13) scheduled for HALN received paravertebral analgesia preoperatively. Postoperative opioid requirements and dynamic visual analog scale pain scores were determined in the recovery room and every 8 hours for 48 hours postoperatively. Data were obtained from medical records and patient interview. RESULTS: The paravertebral analgesia was completed in all 30 patients with a mean visual analog scale score of 3.08 (0-10). Cumulative morphine equivalent doses were 11.82 mg (0-41 mg), whereas in two other studies, it ranged from 24 to 54 mg. CONCLUSION: PVBs provided excellent analgesia with significant opioid sparing in this pilot series of 30 patients with HALN. Utilization of multimodal analgesia incorporating PVB is recommended for patients presenting for HALN.
