Adding clonidine to nerve blocks for shoulder surgery pain
Treatments studied
Part of Bones, joints & muscles, Injuries & trauma, Pain clinical trials.
This study tests adding a medicine called clonidine to a shoulder nerve block to see if it improves pain relief after keyhole shoulder surgery. It compares two ways of giving the block to find which one works better.
Summary written for real people, not researchers, by Clin2.

This study tests whether adding certain medicines (buprenorphine, clonidine, and a steroid) to an arm “nerve block” during shoulder surgery can help the numbness last longer and improve comfort afterward. It is for adults having shoulder arthroscopy and compares how long the nerve block works.
This study compares two types of numbing injections (nerve blocks) given before shoulder surgery to see which one provides better pain control during and after the procedure. It aims to find the best way to reduce discomfort while using ultrasound guidance.
This study tests whether adding a steroid medicine (dexamethasone) to a nerve block helps control pain better after arthroscopic shoulder surgery. The nerve block uses a sedative (dexmedetomidine) to numb the shoulder area, and the steroid may make the pain relief last longer.
This study compares two types of nerve blocks to reduce pain after shoulder surgery. One block is placed near the neck (interscalene) and the other is placed further away (serratus posterior superior intercostal plane block). The goal is to see which works better and has fewer side effects.
This study compares two types of nerve blocks to see which one provides better pain relief after outpatient shoulder surgery. Participants will receive one of the two blocks, and the study will track their pain and recovery.
This trial compares three different types of nerve blocks to manage pain after shoulder arthroscopy. The goal is to find which block works best for reducing pain and improving recovery.
