Objective: To investigate whether the addition of liposomal bupivacaine abdominal wall blocks to a multimodal analgesic regimen improves postoperative numeric rating scale pain scores and reduces opioid consumption in patients undergoing living liver donation. Patients and Methods: We conducted a single-center, retrospective review of patients who underwent living liver donation from January 1, 2011, through February 19, 2016, and received multimodal analgesia with (block group) or without (control group) abdominal wall blockade. The block solution consisted of liposomal bupivacaine (266 mg) mixed with 30 mL of 0.25% bupivacaine. Both groups received intrathecal hydromorphone. Main outcome measures were pain scores, opioid requirements, time to full diet, and bowel activity. Results: Postoperative day 0 pain scores were significantly better in the block group (n=29) than in the control group (n=48) (2.4 vs 3.5; P=.002) but were not significantly different on subsequent days. Opioid requirements were significantly decreased for the block group in the postanesthesia care unit (0 vs 9 mg oral morphine equivalents; P=.002) and on postoperative day 0 (7 vs 18 mg oral morphine equivalents; P=.004). Median (interquartile range) time to full diet was 23 hours (14-30 hours) in the block group and 38 hours (24-53 hours) in the control group (P=.001); time to bowel activity was also shorter in the block group (45 hours [38-73 hours] vs 67 hours [51-77 hours]; P=.01). Conclusion: Abdominal wall blockade with liposomal bupivacaine after donor hepatectomy provides an effective method of postoperative pain control and decreases time to full diet and bowel activity.
