Personalized numbing dose for arm surgery
Part of Pain clinical trials.
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.
Summary written for real people, not researchers, by Clin2.

- You are between 18 and 80 years old
- You are scheduled for elective surgery on one arm or hand

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.
This trial tests whether a long-acting numbing medicine called liposomal bupivacaine, given through a nerve block, reduces the pain that can return after the block wears off following orthopedic surgery. If you're having arm or leg surgery, this could help you feel better and need less pain medicine.
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 is for people having hand or forearm surgery. It aims to find the smallest effective dose of a numbing medicine (ropivacaine) that works well to block pain during the procedure.
This study compares two numbing methods for arm surgery to see which one works better for pain relief. It might help you have less pain during and after surgery.
This study tests a device that measures pain levels during upper arm surgery when patients receive a nerve block (numbing medicine injected near the nerve). The goal is to understand if this monitoring tool helps doctors give the right amount of anesthesia so patients stay comfortable.
