Nerve block duration in people on vs. off opioids
Part of Pain clinical trials.
This study compares how long a numbing nerve block lasts in people who take strong pain medicines (opioids) every day versus those who do not take opioids. It will help doctors understand if pain relief lasts a different amount of time for people on long-term opioids.
Summary written for real people, not researchers, by Clin2.

This study compares two different nerve block techniques for pain relief after total knee replacement surgery. It tests whether a block of the nerve in the thigh plus a block around the knee joint works better than the thigh block plus a block of specific knee nerves.
This study compares two common numbing medications used together versus one alone for nerve-blocking surgery on the lower leg. Researchers want to see which approach works better and lasts longer for pain relief after your procedure.
This trial looks at using ultrasound-guided nerve blocks (injecting numbing medicine near nerves) to control pain in people with severe injuries affecting multiple body areas. It aims to see how well these blocks work and if they help with recovery.
This study compares two ways of using numbing injections during total knee replacement surgery to see which better reduces pain. It may help you and your care team understand the safest and most effective pain-control approach.
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 a method to prevent pain from returning after a nerve block wears off following orthopedic surgery. It may help patients who have surgery on an arm or leg and want to reduce pain after the block ends.
