Could a simple mineral cut opioid use in Kids' surgery?
NCT ID NCT06563349
First seen Aug 20, 2026 · Last updated Aug 21, 2026 · Updated 1 time
Summary
This trial investigates whether giving magnesium sulfate through an IV during anesthesia can reduce the need for opioid painkillers in children undergoing laparoscopic appendectomy. It also looks at how magnesium affects heart rate, blood pressure, and stress hormone responses to surgery. Half of the 188 children will receive magnesium, while the other half gets a placebo (saline). The goal is to see if magnesium provides better pain control with fewer opioids.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Intravenous magnesium sulfate infusion
- What this could lead to
- If effective, this could offer a safer way to manage pain in children after surgery, potentially reducing opioid use and related side effects.
- What could go wrong
- This is a single-center trial, and results may not apply broadly. Magnesium can affect heart rhythm and blood pressure, so safety monitoring is critical.
