Stopping Opioid Overuse in Obstetrics To Halt Exposure Trial — SOOOTHE  

Pain, Postoperative Clinical Trial

Official title:
Stopping Opioid Overuse in Obstetrics to Halt Exposure Trial

Clinical Trial Summary

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.

Clinical Trial Description

Nearly 1 in 3 women in the US deliver by cesarean delivery. After cesarean delivery, approximately 75-87% percent of women are discharged from the hospital with an opioid prescription. Most women fill that prescription and 1% continue to use those opioids 90 days after delivery despite no longer requiring them for pain control, predisposing them to opioid dependence. This study aims to determine if transverse abdominis plane (TAP) block using bupivacaine liposome suspension injection (EXPAREL®) significantly reduces the use of opioid medications after discharge in women undergoing scheduled cesarean delivery. The study is a proposed double-blinded, randomized controlled trial. Pregnant women who have completed 37 weeks gestation and are scheduled for cesarean delivery will be randomized to receive a TAP block with 80 ml of mixed liposomal bupivacaine or saline. Based on its use in other surgical settings, the investigators hypothesize that women who receive a liposomal bupivacaine TAP block will use significantly less opioids by postoperative day 7 as calculated in morphine milligram equivalents. In addition to overall consumption of opioids after discharge, other aims to be studied include inpatient opioid use, effect on pain scores, rates of postpartum depression, patient-perceived quality of breastfeeding, patient quality of recovery, and composite adverse outcomes. With better overall pain control and less dependence on opioids postpartum, liposomal bupivacaine TAP blocks at the time of scheduled cesarean delivery may offer a highly effective analgesic alternative that can help shift the tide in the ongoing opioid epidemic among reproductive females. ;
