Nerve block

Hand, wrist, and forearm surgeries often cause significant pain, and an axillary nerve block is a standard way to numb the arm. In the classic approach, doctors target the nerves around the axillary artery under ultrasound. A newer interfascial approach deposits anesthetic betwee…

This trial tests whether an ultrasound-guided nerve block called QLESP can reduce pain and the need for opioid painkillers after robot-assisted partial nephrectomy for kidney cancer. Adults scheduled for this surgery are randomly assigned to receive either the QLESP block or a st…

This study compares two ultrasound-guided nerve blocks—external oblique intercostal plane block and erector spinae block—for pain relief after liver surgery in cancer patients. Fifty-two adults will receive one of the two blocks, and researchers will measure pain scores and morph…

This trial tests two different nerve block methods to control pain after laparoscopic gallbladder removal. Sixty adults undergoing elective surgery will receive either a newer single-puncture block or an external oblique intercostal plane block, while a control group gets only st…

Spinal anesthesia wears off at different speeds in different people, even when they get the same dose. Researchers are building machine learning models to predict how long sensory and motor blocks will last in adults having elective surgery. The study will record body measurement…

This study looks at whether sarcopenia—age-related muscle loss—changes how well regional nerve blocks work for people having upper limb surgery. Researchers will compare patients with and without sarcopenia, measuring how quickly the block takes effect, how well it controls pain,…

This study looks at severely injured adults with multiple traumatic injuries who receive one or more nerve blocks for pain. Researchers want to see if having more blocks improves pain control, reduces opioid use, and helps patients regain mobility faster, or if it increases risks…
