This study compares two types of nerve blocks—erector spinae plane block and caudal block—to see which provides better pain relief for children aged 1 to 8 years after lower abdominal surgery. About 78 children will be enrolled, and their pain levels, safety, and parent satisfact…

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 tests two different methods of using pulsed radiofrequency on a shoulder nerve to reduce pain and improve movement in people with long-term shoulder pain from rotator cuff tendinopathy. About 32 adults aged 40 to 80 will be randomly assigned to one of the two approache…

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 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 headache days and pain intensity, and to find out which patients respond best based on frailty and nutrition. 10…

This study tests a gel called Sensovisc, injected into the hip joint, to see if it safely reduces pain and improves movement in people with hip osteoarthritis. About 25 adults with moderate hip arthritis will receive the injection and be monitored for 6 months. The goal is to rel…

This study tests whether a higher dose of the steroid dexamethasone given during gallbladder surgery helps patients recover better than a moderate dose. About 135 adults having planned laparoscopic gallbladder removal will be randomly assigned to receive one of two doses. The res…

This study looks at how sleep quality before and after shoulder replacement surgery relates to recovery. Twenty adults having shoulder replacement will wear a sleep tracker for a week before surgery and again six months after. Researchers will compare sleep data with standard sho…

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 looks at how different levels of muscle relaxation during abdominal surgery affect lung pressure and the risk of breathing problems after the operation. About 128 adults having planned abdominal surgery will be randomly assigned to receive either deep or moderate muscl…

This study looks at 70 men having robot-assisted prostate cancer surgery. It compares two low gas flow settings (1 liter vs 0.5 liter per minute) for the anesthesia drug sevoflurane. The goal is to see which flow keeps breathing and blood gases more stable during the operation. R…

This study compares two breathing tube devices (SafeLM™ video laryngeal mask and i-gel®) in 70 adults having shoulder surgery while sitting up. The goal is to see which device keeps the airway sealed better and safer after patients are moved to a sitting position. Results will he…

This study looks at two ways of helping older patients breathe when they first go under anesthesia for surgery. One method uses manual bag squeezing, the other uses a machine called AutoFlow. Researchers will measure oxygen levels in the brain and body to see which method works b…

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. Researchers will measure irisin in blood samples before, 30 minutes after, and 24 hours after surgery. They…

This study looks at whether a specific way of using the breathing machine during robot-assisted prostate surgery can help patients breathe better after the operation. The special position and gas used during surgery can strain the lungs. The trial will compare the new method to s…

This study watches how the lungs work during different stages of robotic surgery. It will include 65 adults having robotic surgery under general anesthesia. The goal is to measure changes in breathing efficiency and lung stiffness to help doctors improve care.

This study looks at whether a simple neck ultrasound can help predict a sudden drop in blood pressure during C-section in women with preeclampsia (a pregnancy complication involving high blood pressure). About 96 women will have their neck vein measured before receiving spinal an…
