Fentanyl vs nalbuphine for pain after gallbladder surgery
Treatments studied
Part of Digestive system, Pain clinical trials.
This trial tests whether adding fentanyl or nalbuphine to a common numbing medicine (bupivacaine) during gallbladder removal surgery can improve pain relief afterward. It is for generally healthy adults who are not pregnant and have no serious gallbladder problems or drug allergies.

This trial compares two pain medicines added to a standard numbing shot (bupivacaine) for gallbladder surgery done through small incisions (laparoscopic cholecystectomy). The goal is to see which medicine provides better pain control after surgery.
This study compares two ways to manage pain during laparoscopic gallbladder removal: one using opioids and one without. The goal is to see if pain control can be as effective without opioids, which may have fewer side effects.
This trial finds the right dose of a pain medication (sufentanil) for adults having planned gallbladder removal surgery. You take part by getting the drug during surgery so doctors can find the safest and most effective amount.
This study gives morphine during gallbladder removal surgery to see how it affects pain afterward. It may help you have less pain and recover more comfortably.
This trial compares two drugs, ketamine and fentanyl, added to the standard numbing medicine (bupivacaine) to see which works better for pain control during laparoscopic gallbladder removal. Both are injected into the belly area during surgery.
This study compares two pain medications, fentanyl and remifentanil, used during laparoscopic gallbladder removal. The goal is to see which one helps you recover bowel function faster and control pain better after surgery.
