Summary
This study tested whether giving lidocaine through a vein during weight-loss surgery helps patients recover faster and need less strong pain medicine. 180 adults scheduled for bariatric surgery received either lidocaine or a placebo (salt water). Researchers measured how much painkiller they used and how quickly they were ready to leave the hospital.
