Using heat and blood flow to check nerve block success
Part of Pain clinical trials.
This study tests a new way to quickly tell if a nerve block (numbing of the arm) is working before surgery. It uses a special camera to measure heat and a sensor on your finger to check blood flow, which may help your doctors give you better pain relief.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 70 years old
- You are in generally good health (classified as ASA I–III)
- You do not have a bleeding disorder
- You are not allergic to local anesthetics (numbing medicines)
- You do not have nerve damage, poor blood flow (like Raynaud's), or skin infections in the affected arm
- No tourniquet will be used during your surgery

Other trials that look related to this one.
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 study uses a special camera (infrared thermography) and a fingertip sensor (perfusion index) to quickly detect if a nerve block is working in one area of the arm. This could help anesthesiologists adjust the block more precisely during surgery on your arm.
This study looks at how a nerve block given near the collarbone affects blood flow in the arm during hand surgery. It may help doctors understand how the block works and improve pain control.
This study tests two ways of doing a nerve block (numbing medicine injected near nerves) to relieve pain during and after surgery on the arm or hand. The goal is to find out if adding a special nerve-stimulating tool can make the block work better and provide longer pain relief.
This study tests whether using a slightly different arm position (at a 120° angle instead of the usual 90°) makes a nerve block for hand, wrist, or forearm surgery more effective and safer. If you are having surgery on your arm or hand, this could help improve your pain control.
This study monitors the pressure used while giving a nerve block (numbing shot) in the armpit area for hand, wrist, or forearm surgery. The goal is to see if real-time pressure monitoring can help make the block safer and more comfortable.
