Can a single dose extend Post-Cesarean pain relief?
NCT ID NCT07773220
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This trial tests whether a single intravenous dose of magnesium sulphate or dexamethasone, given before an ultrasound-guided abdominal nerve block, can improve pain control after a planned cesarean section. Eighty women undergoing the procedure will be randomly assigned to receive one of the two add-ons, and their pain will be tracked for 24 hours. The goal is to see which approach provides longer-lasting relief and reduces the need for extra pain medication.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Magnesium sulphate or dexamethasone given as a single intravenous dose before an ultrasound-guided abdominal nerve block
- What this could lead to
- If one works better, it could point to a simple, safe way to improve pain relief after cesarean delivery, reducing the need for opioids.
- What could go wrong
- This is a small, early-stage trial, and results may not apply broadly. Both drugs can have side effects, and the benefit over standard care is uncertain.
