ObjectiveWe sought to determine the effect of a subcostal transversus abdominis plane (TAP) block with liposomal bupivacaine on postoperative maximal pain score and length of hospital stay among women undergoing robotic-assisted hysterectomy.MethodsThis was a retrospective study comparing patients before and after consistent implementation of TAP blocks with liposomal bupivacaine during robotic-assisted hysterectomies at a single academic institution. Analysis compared patient demographic and operative characteristics by TAP block use, along with outcomes of interest, including postoperative pain and length of hospital stay.ResultsThere was a statistically significant decrease in maximal numerical rating scale pain scores, presence of nausea and vomiting, and length of hospital stay in those who had a TAP block with liposomal bupivacaine compared with those who did not receive a TAP block. These differences remained even after adjustment for potential confounders.ConclusionsIn this retrospective study, liposomal bupivacaine used in a TAP block was a useful method to provide postoperative pain control in patients undergoing robotic-assisted hysterectomy and was associated with lower postoperative maximal pain scores and length of hospital stay.
