Could a common Anti-Nausea drug help kids sleep better after surgery?
NCT ID NCT07777276
First seen Aug 20, 2026 · Last updated Aug 21, 2026 · Updated 1 time
Summary
This trial asks whether two standard anti-nausea medications given during anesthesia—dexamethasone and ondansetron—affect children's sleep, behavior, and recovery after surgery. About 500 children aged 2-15 having minor procedures will be randomly assigned to receive one of the two drugs, without knowing which. Parents will report on sleep quality and recovery for a week after surgery, and some children will also wear monitors to track sleep before and after.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Dexamethasone (IV) or Ondansetron (IV), given during anesthesia to prevent postoperative nausea and vomiting
- What this could lead to
- If one drug is found to disturb sleep less, it could become the preferred choice for children undergoing surgery, improving their recovery and comfort.
- What could go wrong
- This is a phase 4 trial, but the effects on sleep are not yet proven. Results may vary by child, and the study only looks at short-term recovery, not long-term outcomes.
