Summary

This study tests whether adding magnesium sulfate to the standard epidural pain medicine (morphine) can reduce the chance of urinary retention after a C-section. About 1 in 3 women have trouble urinating after surgery, often needing a catheter. The trial will compare magnesium plus morphine against morphine alone in 290 women. If successful, it could offer a simple way to improve recovery and comfort.

What this could mean

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

Active substance: magnesium sulfate
What this could lead to: If it works, this could offer a simple, low-cost way to prevent urinary retention after C-section, reducing the need for catheters and improving recovery.
What could go wrong: This is a single-center Phase 4 trial with 290 participants, so results may not apply broadly. The benefit seen in a prior retrospective study may not hold up in this more rigorous test.
