Summary

This trial tests whether a continuous infusion of numbing and anti-inflammatory drugs directly into the C-section wound can control pain as well as a standard spinal injection of morphine. The study enrolls women having a planned C-section with a single, healthy pregnancy. Researchers will compare pain scores, side effects, and the risk of long-term scar pain between the two approaches.

What this could mean

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

Active substance
ropivacaine and diclofenac (wound infusion) vs. morphine (spinal injection)
What this could lead to
If the wound infusion works as well as morphine, it could offer a safer, more convenient option for post-cesarean pain relief with fewer side effects.
What could go wrong
This is a small, single-center Phase 4 trial, so results may not apply to all patients. The experimental treatment might not match morphine's effectiveness or could have its own side effects.
