Early detection of nerve block effects using heat imaging
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 65 years old.
- You are otherwise healthy or have only mild health problems (ASA I or II).
- You are scheduled for elective surgery on one arm or hand.
- You do not have nerve damage, Raynaud's disease, or poor blood circulation.
- You do not have diabetes with nerve complications.
- You are not allergic to local anesthetics and your body mass index (BMI) is below 35.
- Your arms have similar temperatures before the procedure.

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.
This study tests if a special heat-sensing camera can predict whether a nerve block will work for children having hernia surgery. If successful, this could help doctors know right away if the block is effective.
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 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 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.
This study looks at whether simple, noninvasive measurements of blood flow in your finger and arm can predict how well the numbing medicine (nerve block) works before your arm surgery for dialysis access. The goal is to make sure you get the best pain relief during the procedure.
