The Efficacy of Liposomal Bupivacaine on Postoperative Pain Following Abdominal Wall Reconstruction: A Randomized, Double-blind, Placebo-controlled Trial

alexandrossfakianakis shared this article with you from Inoreader The Efficacy of Liposomal Bupivacaine on Postoperative Pain Following Abdominal Wall Reconstruction: A Randomized, Double-blind, Placebo-controlled Trial via Annals of Surgery - Most Popular Articles Objective: To study the efficacy of liposomal bupivacaine on postoperative opioid requirement and pain following abdominal wall reconstruction. Summary Background Data: Despite the widespread use of liposomal bupivacaine in transversus abdominis plane block, there is inadequate evidence demonstrating its efficacy in open abdominal wall reconstruction. We hypothesized that liposomal bupivacaine plane block would result in decreased opioid requirements compared with placebo in the first 72 hours after surgery. Methods: This was a single-center double-blind, placebo-controlled prospective study conducted between July 2018 and November 2019. Adult patients (at least 18 yrs of age) undergoing open, elective, ventral hernia repairs with mesh placed in the retromuscular position were enrolled. Patients were randomized to surgeon-performed transversus abdominis plane block with liposomal bupivacaine, simple bupivacaine, or normal saline (placebo). The main outcome was opioid requirements in the first 72 hours after surgery. Secondary outcomes included total inpatient opioid use, pain scores determined using a 100 mm visual analog scale, length of hospital stay, and patientreported quality of life. Results: Of the 164 patients who were included in the analysis, 57 patients received liposomal bupivacaine, 55 patients received simple bupivacaine, and 52 received placebo. There were no differences in the total opioid used in the first 72 hours after surgery as measured by morphine milligram equivalents when liposomal bupivacaine was compared with simple bupivacaine and placebo (325 ± 225 vs 350 ± 284 vs 310 ± 272, respectively, P = 0.725). Similarly, there were no differences in total inpatient opioid use, pain scores, length of stay, and patient-reported quality of life. Conclusions: There are no apparent clinical benefits to using liposomal bupivacaine transversus abdominis plane block when compared with simple bupivacaine and placebo for open abdominal wall reconstruction.
