Does a collarbone nerve block affect breathing?
Part of Lungs & breathing clinical trials.
This study looks at how often the diaphragm (the muscle that helps you breathe) goes partially numb after a nerve block near the collarbone for arm or shoulder surgery. It uses ultrasound to check breathing function before and after the block.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 60 years old.
- You are not pregnant (if you have ovaries).
- You have no known lung disease (like asthma or COPD), muscle/nerve disease, or diaphragm problems.
- You are not allergic to numbing medicines used for blocks (like lidocaine).
- Your BMI is less than 35 (a measure of weight relative to height).

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 study compares how three different types of nerve blocks affect your diaphragm (the muscle that helps you breathe) during shoulder surgery. The goal is to find which block is best for preserving breathing function.
This study compares two different arm positions (90 degrees versus 120 degrees) during a nerve-blocking injection that numbs your arm before hand, wrist, or forearm surgery. Researchers want to see which position works better for the anesthesia and helps you recover safely.
This study compares three different nerve blocks to see which one causes less breathing trouble and provides better pain relief after arthroscopic shoulder surgery. It may help patients who are having shoulder surgery and want to avoid side effects like muscle weakness.
This study tests a special numbing shot (nerve block) around the shoulder to see how it affects the muscle that helps kids breathe (the diaphragm) during and after arm surgery. It may help doctors choose safer pain methods for school-aged children.
This trial compares two different ultrasound-guided methods of numbing the nerves in your upper arm and shoulder for surgery on your hand, wrist, or forearm. The goal is to see which technique works better and is safer for patients.
