Numbing medication for shoulder surgery and breathing
Treatments studied
Part of Bones, joints & muscles, Injuries & trauma, Pain clinical trials.
This trial compares two types of numbing medications (liposomal bupivacaine and standard bupivacaine) given as a nerve block for shoulder surgery. Researchers want to see which one works better for pain relief and causes fewer problems with your breathing afterward.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Scheduled for elective (planned, non-emergency) shoulder surgery on one side only
- Able to see normal movement of your diaphragm (breathing muscle) on ultrasound before surgery
- Age 18–80 years old
- Generally healthy or with mild-to-moderate medical conditions (ASA I–III status)
- BMI (body weight relative to height) between 18–30 kg/m²
- No allergies to numbing medications, blood clotting problems, or active infection at needle site

This trial tests different volumes of a long-lasting numbing medicine (Exparel) injected around the shoulder nerves before arthroscopic surgery. The goal is to find the dose that provides the best pain relief.
This study compares two different strengths of local anesthetic used in a nerve block for shoulder replacement surgery. The goal is to see if one strength helps reduce pain that can come back as the block wears off.
This study tests a numbing medicine injected near the shoulder to see if it gives better pain relief after arthroscopic shoulder surgery than the standard approach. It might help you recover with less pain and fewer side effects.
This study checks how a nerve block for upper arm surgery affects the diaphragm, the muscle that helps you breathe. It uses a long-lasting numbing medicine to see if breathing is affected.
This trial tests if using an ultrasound to measure the size of your nerve before surgery can help doctors give you the right amount of numbing medicine, which may mean a more effective block with fewer side effects.
This trial tests a long-lasting numbing medicine injected near the back muscles to reduce pain after open surgery on the liver, stomach, or pancreas. It may help you need fewer painkillers and recover more comfortably.
