Nerve block study for healthy volunteers
Treatments studied
This study tests a numbing injection around a nerve in the wrist to see how it affects blood flow and sensation in the hand. It may help doctors understand how to treat hand pain or circulation problems.
Summary written for real people, not researchers, by Clin2.

- You are between 18 and 50 years old.
- You are generally healthy (no serious medical conditions).
- You have two hands with all five fingers and no major hand or arm injuries.

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 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 trial studies whether a numbing “nerve block” can reduce long-lasting nerve pain caused by diabetic neuropathy. You may keep your usual pain medicines, and the study will mainly check whether you fit the safety and diagnosis criteria.
This study tests whether numbing the nerves in your painful arm or leg (with a nerve block) can help reduce central pain after a stroke. It aims to find out how the nerves outside your brain and spinal cord may be involved.
This study tests a numbing injection (nerve block) placed in the abdominal wall using ultrasound guidance to see how well it relieves pain. It aims to help adults who are generally healthy and need this type of pain control.
This trial is building a database to study ultrasound-guided nerve blocks (injecting numbing medicine around nerves using ultrasound). It may help researchers learn how to better manage pain.
