Using Dexamethasone to Enhance Pain Relief After Colorectal Surgery

Transversus Abdominis Plane Blocks With and Without Dexamethasone: A Randomized Clinical Trial in Minimally Invasive Colorectal Surgery

Phase1; Phase2 Interventional University of Saskatchewan · NCT05432934

This study is testing if adding dexamethasone to local pain relief injections can help patients feel less pain after laparoscopic colorectal surgery and reduce the need for opioids.

What this trial studies

This study investigates the use of dexamethasone as an adjunct to local anesthetics in transversus abdominis plane (TAP) blocks for patients undergoing laparoscopic colorectal surgery. The goal is to prolong the analgesic effects of the TAP block, which is a regional anesthesia technique that can reduce postoperative pain and opioid use. By comparing the effectiveness of TAP blocks with and without dexamethasone, the study aims to optimize pain management strategies in the perioperative setting. The research focuses on improving recovery outcomes and minimizing opioid-related side effects.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old who are scheduled for elective or urgent laparoscopic colorectal surgery and are classified as ASA class I-III.

Not a fit: Patients who may not benefit include those undergoing emergency or open surgeries, those with significant comorbidities, or those who are unable to consent or respond to pain assessments.

Why it matters

Potential benefit: If successful, this approach could lead to improved pain management and faster recovery for patients undergoing colorectal surgery.

How similar studies have performed: Other studies have shown promising results with the use of regional anesthesia techniques like TAP blocks, suggesting that this approach may be effective, though the specific combination with dexamethasone is being explored in this novel context.
