Early detection of nerve block failure during arm surgery
Part of Injuries & trauma, Pain clinical trials.
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.
Summary written for real people, not researchers, by Clin2.

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.
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 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.
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 compares two types of nerve blocks (subcoracoid tunnel block and costoclavicular block) to see which works better for numbing the arm during surgery. If you are having a short surgery on your lower arm, hand, or wrist, this trial may help find the most effective pain relief.
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.
