Summary

This study compares ketamine to morphine for treating acute pain in children visiting the emergency department. Over 1,000 children with abdominal pain or broken bones will receive either drug. The goal is to see if ketamine works as well as morphine but with fewer side effects.

What this could mean

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

Active substance
Ketamine hydrochloride and morphine sulphate
What this could lead to
If ketamine works as well as morphine, it could offer a safer, non-opioid option for managing acute pain in children.
What could go wrong
This is a non-inferiority trial, so ketamine might not be as effective as morphine. Side effects from ketamine are also possible.
