Spotting nerve block failure with heat and blood flow
Part of Pain clinical trials.
This trial tests whether measuring skin temperature and blood flow can quickly tell if a nerve block for arm surgery has failed. It might help patients receive prompt additional pain relief.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 70 years old
- Your physical health status is class I, II, or III according to the anesthesia rating system
- The arm receiving the nerve block has no nerve damage, skin infection, or poor blood flow
- You do not have a bleeding disorder or allergy to numbing medicines
- A tourniquet will not be used on your arm during the procedure

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 tests a new way to detect nerve block failure early during anesthesia for arm/hand surgery. It uses infrared temperature imaging and a sensor to check blood flow, aiming to improve safety and success of the anesthesia.
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 study measures how a nerve block (infraclavicular block) affects your pulse wave, which is a sign of blood flow. If you are having planned hand surgery and meet the health requirements, you may be able to join.
This study compares how well artificial intelligence and anesthesiologists can identify nerve locations using ultrasound before arm surgery. It helps test whether AI can accurately guide nerve-blocking injections that numb the arm during surgery.
This trial tests if blood flow measurements can predict how well a nerve block works during vascular access surgery. It aims to improve pain control for procedures like fistula creation.
