Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This trial compares two ways to manage pain after open inguinal hernia repair: an ultrasound-guided nerve block (transversalis fascia plane block) versus a low-dose injection of morphine into the spinal fluid. The goal is to see which method reduces the need for extra painkillers in the first 24 hours after surgery. The study includes 80 adults undergoing elective hernia repair under spinal anesthesia.

What this could mean

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

Active substance
bupivacaine
What this could lead to
If one method proves better, it could reduce the need for opioids after hernia surgery, leading to fewer side effects and faster recovery.
What could go wrong
This is a small, early-stage trial with only 80 participants, so results may not apply to everyone. Both methods have known side effects like nausea or rare nerve issues.
