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.
