This study tests whether playing instrumental music through headphones or reducing noise in the operating room can lower the amount of anesthesia and painkillers needed for children aged 3-18 during surgery. 180 children will be randomly assigned to music, noise reduction, or sta…

This study tests a new type of nerve block (PENG block) for people with chronic shoulder pain that hasn't improved with other treatments. 45 adults will get an ultrasound-guided injection of numbing medicine and steroid. Researchers will measure pain, shoulder function, and satis…

This study compares two types of ultrasound-guided injections for people with chronic neck pain caused by small joints in the spine (facet joints). About 130 adults aged 18-80 with at least 3 months of neck pain will receive either a standard nerve block or a newer block targetin…

This study will compare two types of nerve blocks—erector spinae plane block and caudal block—in 78 children aged 1 to 8 years undergoing lower abdominal surgery. The goal is to see which method provides better pain control after surgery, using a standard pain scale. Both blocks …

This study compares two doses of dexamethasone (a steroid) given during gallbladder surgery to see which works better for reducing nausea, pain, and inflammation after the operation. About 135 adults having laparoscopic gallbladder removal will be randomly assigned to receive eit…

This study tests a minimally invasive nerve treatment called pulsed radiofrequency (PRF) for chronic migraine in people aged 65 and older. The goal is to see if it reduces pain and headache days, and to find out which patients respond best. Researchers will also look at frailty a…

This study tests a gel called Sensovisc, injected into the knee joint to reduce pain and improve movement in people with knee osteoarthritis. About 75 adults with moderate knee arthritis will receive the gel and be followed for 6 months. The goal is to see if the gel safely eases…

This study tests a gel called Sensovisc, made of sodium hyaluronate, injected into the hip joint to relieve pain from osteoarthritis. The gel aims to restore the joint's natural fluid, reducing pain and improving movement. Researchers will track 25 adults with moderate hip arthri…

This study looks at how chloride levels in the blood change during a type of prostate surgery called HoLEP. Researchers want to see if these changes affect how patients recover. The study is observational, meaning no new treatments or procedures are being tested—just routine care…

This study looks at how a man's lungs behave during a specific type of prostate surgery called HoLEP. Researchers will measure lung pressure and stiffness during the operation in 45 men. The goal is simply to observe and learn, not to change any treatments.

This study will track sleep patterns in 20 people before and after reverse shoulder replacement surgery. Participants will wear a MotionWatch 8 sleep tracker for a week before surgery and again 6 months after. The goal is to see if better sleep is linked to better recovery and sh…

This study looks at three different ways to set the breathing machine during robotic surgery to find which one best protects the lungs and helps patients breathe better after surgery. About 120 adults having elective robotic surgery will take part. The goal is to see if adjusting…

This study looks at two different gas flow levels (low vs. minimal) for the anesthesia drug sevoflurane during robot-assisted prostate cancer surgery. The goal is to see which flow rate better maintains healthy breathing and oxygen levels during the procedure. About 70 men having…

This study tests whether a new way of setting the breathing machine during robot-assisted prostate surgery can help patients breathe better after the operation. The special position and air pressure used in this surgery can make breathing harder. The study will compare the new me…

This study compares two breathing devices (SafeLM and i-gel) used during shoulder surgery when patients are in a sitting position. Researchers will measure how well each device seals the airway and how safe they are. The study involves 70 adults aged 18-80 who are having shoulder…

This study will check if an ultrasound of the internal jugular vein in the neck can predict a sudden drop in blood pressure during spinal anesthesia for C-section in women with preeclampsia. Researchers will measure the vein's collapsibility before surgery and track blood pressur…

This study looks at how deep muscle relaxation (using rocuronium) during abdominal surgery affects lung pressure and breathing problems after surgery. Researchers will compare deep versus moderate relaxation in 128 adults having open abdominal surgery. The goal is to see if one a…

This study compares two types of anesthesia—general anesthesia and a nerve block—in 90 adults having forearm fracture surgery. Researchers will measure blood levels of irisin, a hormone linked to inflammation and healing, before and after surgery. The goal is to see if the type o…
