Regional anesthesia

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 adding magnesium sulfate to a standard nerve block improves pain control after shoulder arthroscopy. About 84 adults having outpatient shoulder surgery will receive the nerve block with or without magnesium. Researchers will measure how long pain relief l…

This trial tests whether adding a steroid called dexamethasone to the standard pain regimen extends pain relief after arthroscopic shoulder surgery. Adults aged 18 to 65 receive a nerve block and dexmedetomidine, then either dexamethasone or a placebo before surgery. Researchers …

This trial tests whether a nerve block called a lateral quadratus lumborum block (QLB) can control pain after a C-section as well as the standard treatment, spinal morphine, but with fewer side effects. The study includes women having an elective C-section under spinal anesthesia…

This study compares two types of nerve blocks to see which one controls pain better after open gallbladder removal. Sixty-six adults will receive either an erector spinae plane block or an external oblique intercostal plane block before surgery. Researchers will measure pain scor…

This study tests whether an AI-powered app can improve follow-up for patients recovering from surgery with a continuous nerve block for pain. 166 adults will use either the AI app or a standard automated messaging system. The goal is to see if the AI reduces the number of times p…

This study tests two different ultrasound-guided nerve blocks to see which one provides better pain relief after breast cancer surgery. 70 adults aged 18-65 will be randomly assigned to receive one of the two blocks. The goal is to reduce the need for strong painkillers and impro…
