Ultrasound-guided arm block with or without nerve stimulator
Part of Pain clinical trials.
This study compares two ways to numb the arm for surgery from the elbow down to the hand. Both methods use an ultrasound to guide the numbing medicine, but one also uses a small device (nerve stimulator) to help find the right spot. The goal is to see if adding the nerve stimulator leads to better pain relief during and after surgery.

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.
This trial compares two types of ultrasound-guided nerve blocks for obese patients having surgery on or below the elbow. The goal is to find which approach works best for this group.
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 trial compares three ways to control pain during forearm surgery: different nerve blocks versus using a PCA pain pump. It may help find the approach that gives better pain relief and comfort after surgery, especially for longer procedures.
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.
