New study aims to find best pain relief for kids after kidney surgery
NCT ID NCT07346417
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two types of nerve blocks (ESPB and QLB) to see which provides better pain relief for children aged 2-12 after kidney surgery. One hundred children will be randomly assigned to receive one of the two blocks. The main goal is to see how long it takes before they need additional pain medicine, and to monitor pain scores and side effects like nausea.
