Comparing pain relief options for gallbladder removal surgery
Treatments studied
Part of Brain & nervous system, Pain clinical trials.
This study compares three pain-relief methods before gallbladder removal surgery to find which is most effective and safe. It tests a numbing injection near the surgical site, a nerve block in the back, and a spinal injection of morphine.

This trial tests a nerve block injection in the abdominal wall to reduce pain after gallbladder removal surgery. It may help patients recover more comfortably.
This study compares two ways of giving pain relief after gallbladder removal surgery: an injection of numbing medicine around the belly muscles (guided by ultrasound) versus a simple injection into the skin near the surgery cuts. The goal is to see which method provides better pain control and comfort after surgery.
This study tests two different strengths of a numbing medicine injected after gallbladder surgery to see which one gives better pain relief. It may help reduce pain after your operation.
This study compares two types of nerve blocks to see which one provides better pain relief after laparoscopic gallbladder removal. It aims to help patients recover with less discomfort and fewer pain medications.
This study compares two types of pain-relieving injections (nerve blocks) given during gallbladder removal surgery. The goal is to see which one provides better pain control after the operation, helping you recover more comfortably.
This study tests whether a numbing injection in the back (erector spinae plane block) helps reduce anesthesia needs during gallbladder surgery. It compares two anesthesia methods to see which works better for pain control and recovery.
