Conditions

Bariatric Surgery, Cardiac Surgery With Sternotomy, Post-operative Pain

Brief summary

This is prospective, randomized study. The purpose of this study is to evaluate whether the addition of Suzetrigine to well established multimodal pain regimen for participants undergoing bariatric patients undergoing weight-loss surgery and cardiac patients undergoing sternotomy will reduce post-operative opioid consumption and pain scores.

Interventions

DRUGSuzetrigine

Suzetrigine is a new pain medication that works by blocking a specific sodium channel (NAV 1.8) in the peripheral nerves and preventing pain signals from reaching the spinal cord and brain.

Design outcomes

Primary

MeasureTime frameDescription
Opioid Consumption5 daysTotal post-operative opioid consumption measured daily in total morphine milligram equivalents.

Secondary
