Using Pecs blocks with Exparel for pain management in breast reconstruction

A Prospective, Randomized Controlled Trial Investigating Pecs Blocks Types I and II as a Method for Administering the Non-Opioid Anesthetic Exparel in Order to Mitigate Postoperative Narcotic Usage, Pain, Nausea, and Hospital Stay in Patients Undergoing Implant-Based Tissue Expander Breast Reconstruction Surgery

Phase 3 Interventional Northwestern University · NCT05171179

This study is testing if using a combination of a special pain block and a non-opioid pain medicine can help women feel less pain and recover better after breast reconstruction surgery.

What this trial studies

This project investigates the effectiveness of combining Pecs blocks, a local anesthesia technique, with Exparel, a non-opioid analgesic, during breast reconstruction surgery. The study aims to determine if this combination can reduce post-operative pain, opioid use, and nausea while enhancing physical activity after surgery. By utilizing ultrasound-guided Pecs blocks for anesthetic delivery, the research team hopes to demonstrate improved outcomes compared to traditional pain management methods. The trial will focus on patients undergoing implant-based breast reconstruction to assess the benefits of this innovative approach.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who are scheduled for implant-based breast reconstruction surgery.

Not a fit: Patients undergoing flap breast reconstruction or direct-to-implant surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to significantly reduced post-operative pain and lower reliance on narcotics for breast reconstruction patients.

How similar studies have performed: While the use of Pecs blocks and Exparel has shown promise individually, this specific combination in breast reconstruction has not been previously tested.
