Summary

This study will compare two types of pain blocks—caudal block and quadratus lumborum block—in 68 children aged 2 months to 6 years having lower abdominal surgery. Researchers will use a special pain monitor and behavioral pain scores to see which block works better during and after surgery. The goal is to improve pain management and test if the monitor is a reliable tool for children who can't describe their pain.

What this could mean

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

Active substance
bupivacaine
What this could lead to
If successful, this could show which nerve block provides better pain relief for children and confirm if a pain monitor can reliably guide care.
What could go wrong
This is a small, early-stage observational study, so results may not apply to all children or surgeries. The pain monitor's accuracy is still being tested.
