Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

As the opioid epidemic continues on, more research is needed on multi-modal approaches to decrease opioid exposure after common procedures. The aim of this study is to investigate the role of a transverses abdominis block using liposome bupivacaine suspension in reducing use of opioid medications through post-operative day 7. The study is a proposed double-blind, randomized controlled trial.
