Prospective, Randomized, Controlled Comparison of Local Anesthetic Infusion Pump versus DepoFoam Bupivacaine For Pain Management After Unilateral Delayed Deep Inferior Epigastric Perforator Free Flap Reconstruction.

Background: Effective postsurgical analgesia is a critical aspect of patient recovery. The goal of this prospective, randomized, controlled, blinded study was to examine the effect that liposomal bupivacaine delivered via a transversus abdominis plane (TAP) block has on pain control in women undergoing unilateral deep inferior epigastic perforator reconstruction. Methods: IRB approval was granted for this prospective study. Patients were eligible if they were undergoing unilateral, delayed DIEP reconstruction. Patients were randomized to one of three groups; liposomal bupivacaine or bupivacaine TAP block or bupivacaine pain pump. Charts were reviewed for demographics, length of stay, and post-operative narcotic utilization. Results: There were eight patients in the liposomal bupivacaine and bupivacaine groups and 5 patients in the pain pump group. A retrospective cohort of six patients who did not receive any intervention was included. Patients who received a liposomal bupivacaine TAP block used statistically significantly less intravenous and total post-operative narcotics in mg and mg/kg/day compared to all other cohorts. They were able to get out of bed earlier time point. Overall hospital costs were similar amongst the groups. Conclusion: This is the first study to investigate liposomal bupivacaine delivered as a TAP block in a prospective, randomized, blinded study in women undergoing unilateral, delayed abdominally-based autologous breast reconstruction. We were able to demonstrate a significant reduction in intravenous and total narcotic utilization when a liposomal bupivacaine TAP block was utilized. Future studies are needed to prospectively investigate the effect that liposomal bupivacaine would have on immediate and bilateral reconstructions.
