ANESTHESIA, GENERAL

This study tests whether raising carbon dioxide levels slightly during general anesthesia can improve blood flow to the brain before clot removal in stroke patients. Fifty adults with large-vessel stroke will be randomly assigned to either normal or moderately high carbon dioxide…

This trial tests a new device called ResQ that listens to heart and lung sounds through a soft probe in the esophagus to predict if a patient needs more fluids during surgery. Researchers will compare its accuracy to the standard method using an arterial line. The study involves …

This trial compares two standard anesthesia methods—inhaled sevoflurane versus intravenous propofol—during arthroscopic rotator cuff repair. The goal is to see which one gives surgeons a clearer view inside the shoulder joint, which is important for safety and success. About 110 …

This study compares opioid-free anesthesia to standard opioid-based anesthesia in 600 adults undergoing urological abdominal surgery. The goal is to see if avoiding opioids during surgery reduces the need for painkillers afterward and lowers side effects like nausea. Patients wil…

This study compares two common airway devices (i-gel and Air-Q) used to help children breathe during surgery. Researchers will check how well each device seals the airway and whether air leaks into the stomach, using ultrasound for safe and accurate measurements. The goal is to f…

This study observes 50 adults having surgery to understand why their blood pressure drops. Researchers will use machine learning to find patterns in how different patients respond to treatment. The goal is to create personalized recommendations for managing low blood pressure dur…

This study looks at how two common anesthesia drugs, propofol and alfentanil, change brain activity during a procedure called ERCP (a scope exam of the bile ducts). Researchers will monitor 20 patients' brain waves and pain signals to better understand how these drugs work togeth…

This study looks at whether giving extra oxygen or gentle air pressure to the lung that is not being used during lung surgery can lower the risk of problems after the operation. About 177 adults having lung surgery will be randomly assigned to standard care, extra oxygen alone, o…

This study looks at two different ways to measure how well muscles recover from deep paralysis during surgery. About 199 adults aged 18-65 with a healthy weight will take part. The goal is to see which measurement method better ensures it is safe to remove the breathing tube afte…

This study compares two methods of placing a breathing tube during general anesthesia without using opioid painkillers. The goal is to see which method—fiberoptic or direct laryngoscopy—causes less change in heart rate and blood pressure. Researchers will study 90 adults aged 18 …
