Summary

This study tested two types of nerve blocks—Quadratus Lumborum (QL) and Erector Spinae (ESP)—to see which provides better pain relief after abdominal surgery. 100 adults having surgery for colorectal, prostate, or kidney cancer, or gallbladder removal, received one of the blocks before surgery. Researchers measured how much extra pain medicine they needed and their pain scores afterward.

Active substance: ropivacaine injection
What this could lead to: If one block works better, it could lead to better pain control and less opioid use after abdominal surgery.
What could go wrong: This is a small, completed study comparing two techniques. Results may not apply to all surgeries or patients. Both blocks have risks like infection or allergic reaction.
