Comparing two pain medicines for surgery and recovery
Treatments studied
Part of Pain clinical trials.
This study compares two pain medicines (alfentanil and remifentanil) given during surgery to see which one provides better anesthesia quality and helps you recover more comfortably. It may help you recover faster and with less pain after your operation.
Summary written for real people, not researchers, by Clin2.

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.
This trial compares the anesthesia medicines remimazolam and propofol during major surgery to see how patients do afterward. It may help guide which anesthetic is safer or leads to better recovery in higher-risk patients.
This trial tests whether a combination of two medications helps keep blood pressure steady and reduces bleeding during ear, nose, or throat surgery. It is comparing giving just one pain medication versus the pain medication plus a blood pressure-lowering drug.
This study compares two types of anesthesia for emergency abdominal surgery to see if one approach helps you recover better after the operation. The goal is to reduce pain while possibly using fewer strong pain medicines, which may help you feel better sooner.
