Summary

This study aims to find the best volume of pain medicine given through an epidural catheter after open abdominal surgery. Sixty adults will receive different doses every hour, and researchers will track how well pain is controlled and if side effects occur. The goal is to improve recovery and tailor doses for men and women.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
programmed intermittent epidural bolus (local anesthetic)
What this could lead to
If successful, this could establish the optimal epidural dose for better pain control after abdominal surgery, potentially improving recovery and patient comfort.
What could go wrong
This is a small, early-phase dose-finding study (60 participants) and may not confirm effectiveness or generalizability. Results may vary by individual and do not guarantee improved outcomes.
