Abstract

Background: The ongoing epidemic of prescription opiate abuse is one of the most pressing health issues in the United States today. Consequently, analgesic adjuncts, such as multimodal drug regimens and regional anesthetic blocks (like transversus abdominis plane (TAP) block), have been introduced to the perioperative period in hopes of decreasing postoperative opiate use. However, the effect of these interventions on intraoperative opiate use has not been examined. We hypothesized that preoperative TAP block would be associated with decreased intraoperative opiate use during minimally invasive cholecystectomy. Methods: This was a retrospective review of patients undergoing minimally invasive cholecystectomy between June 2018 and January 2021. Perioperative data, operative times, and medication administration data were collected. Intraoperative opiate use was calculated in total morphine equivalent doses (MED) for each patient and adjusted for operative time. Univariate analysis and multivariate linear regression were performed to determine factors affecting intraoperative opiate requirements. Results: 261 patients were included in this study, of which 62 (23.8%) received preoperative TAP block and 199 (76.2%) did not. Preoperative TAP block was associated with decreased intraoperative opiate use (0.199 vs 0.312, p < 0.001), while there were no statistically significant differences associated with other analgesic adjuncts including preoperative acetaminophen (p = 0.485), celecoxib (p = 0.112), gabapentin (p = 0.165), or intraoperative ketorolac (p = 0.200). On multivariate analysis, preoperative TAP block was independently associated with decreased intraoperative opiate use (< 0.001), while chronic cholecystitis on final pathology was associated with increased intraoperative opiate use (p = 0.002). Conclusion: The use of preoperative TAP block was associated with decreased intraoperative opiate use during minimally invasive cholecystectomy and should be considered for routine use. Future research should investigate whether preoperative TAP blocks and a subsequent decrease of intraoperative opiates, also result in a decrease in postoperative opiate use and improvements in postoperative outcomes.
