This study compares two types of ultrasound-guided injections for people with chronic neck pain caused by small joints in the spine (facet joints). 130 adults will be randomly assigned to receive either a standard nerve block or a newer block targeting a different muscle layer. T…

This study tests two different spots to apply a gentle electrical pulse (pulsed radiofrequency) to a nerve in the shoulder to see which works better for long-lasting shoulder pain. About 32 adults with rotator cuff-related pain will be randomly assigned to one of the two methods.…

This study compares two pain-relief techniques—erector spinae plane block and caudal block—in children aged 1 to 8 years having lower abdominal surgery. The goal is to see which method provides better pain control after surgery, using a standard pain score. About 78 children will…

This study tests a minimally invasive nerve treatment called pulsed radiofrequency for people aged 65 and older with chronic migraine. The goal is to see if it reduces pain and headache days. Researchers will also look at frailty and nutrition to predict who benefits most.

This study looks at whether a moderate or high dose of the steroid dexamethasone, given during surgery, helps people recover better after laparoscopic gallbladder removal. About 135 adults will be randomly assigned to one of two dose groups. The main goals are to see which dose r…

This study tests a gel called Sensovisc that is injected into the hip joint to reduce pain and improve movement in people with hip osteoarthritis. The gel works by helping the joint's natural fluid work better. Researchers will measure pain and function in 25 adults over 6 months…

This study will compare a newer epidural method called dural puncture epidural (DPE) with the standard epidural technique in 100 women having planned C-sections. The goal is to see if DPE provides faster and more complete anesthesia with fewer side effects like low blood pressure…

This study is testing a gel called Sensovisc, which is injected into the knee joint to help reduce pain and improve movement in people with knee osteoarthritis. The gel works by supporting the natural fluid in the joint, making it more slippery and cushioning the knee. About 75 a…

This study looks at whether a simple neck ultrasound can predict a sudden drop in blood pressure during a C-section in women with preeclampsia. Researchers will measure the jugular vein collapsibility before spinal anesthesia and track blood pressure changes afterward. The goal i…

This study watches how robotic surgery changes lung function in real time. Researchers will track breathing mechanics in 65 adults during different stages of surgery. The goal is to find better ways to keep patients breathing safely during these operations.

This study looks at how two types of anesthesia—general anesthesia and a nerve block—affect levels of a hormone called irisin in adults having surgery for a broken forearm. Irisin is linked to inflammation and healing. Researchers will measure irisin in blood before, right after,…

This study looks at two different gas flow rates (low vs. minimal) for anesthesia during robot-assisted prostate removal. The goal is to see which one keeps breathing and oxygen levels more stable during surgery. About 70 men having this procedure will take part, and their blood …

This study looks at whether a new way of setting the breathing machine during robot-assisted prostate surgery can help patients breathe better after the operation. The surgery requires a special body position and air in the belly that can make breathing harder. The study will com…

This study looks at how sleep quality before and after reverse shoulder replacement surgery relates to recovery. Twenty adults with shoulder arthritis or cuff tears will wear a wrist monitor (MotionWatch 8) for a week before surgery and again six months after. Researchers will co…

This study looks at how different levels of muscle relaxation during abdominal surgery affect lung pressure and the risk of breathing problems after surgery. Researchers will compare deep versus moderate relaxation in 128 adults having elective abdominal surgery. The goal is to s…

This study tests three different methods of setting breathing machine pressure during robotic surgery to find which one best protects the lungs and improves oxygen levels afterward. About 120 adults having elective robotic surgery will take part. The goal is to see if adjusting p…

This study compares two breathing tube devices (SafeLM™ and i-gel®) in 70 adults having shoulder surgery while sitting in a beach chair position under general anesthesia. The goal is to see which device keeps the airway sealed and safe after the patient is moved to that position.…
