GENERAL ANESTHESIA

This study tests whether an ultrasound-guided nerve block (sphenopalatine ganglion block) can improve the surgical field and reduce pain in patients having pituitary tumor surgery through the nose. About 70 adults aged 21–60 will be randomly assigned to receive the nerve block pl…

This study tests whether giving a small caffeine tablet under the tongue can help elderly patients (65 and older) wake up faster and feel less confused or agitated after general anesthesia for eye surgery. Researchers will measure how quickly patients open their eyes and how calm…

This study tests whether giving dexmedetomidine and esketamine during and after surgery helps patients feel better and recover faster. About 316 adults having surgery under general anesthesia will take part. The goal is to see if these drugs improve pain, comfort, and emotional w…

This study looks at two muscle relaxant drugs used during anesthesia—rocuronium and cisatracurium—in people with chronic kidney disease. The goal is to see which one leads to fewer lung complications after surgery. About 490 adults will take part, and the results could help docto…

This study is creating a large database to learn more about why some pregnant women receive general anesthesia during a C-section and how it is managed. Researchers will track 5,000 women aged 15-55 across many hospitals to identify patterns and improve care. The goal is to make …

This study compares two types of breathing tubes (i-gel and Protector) used during minor urology procedures under general anesthesia. Researchers will measure how well each tube seals the airway and how easy they are to place. The study involves 100 adults who are healthy or have…

This study looks at whether bladder tumor surgery and general anesthesia cause short-term memory or thinking problems. Researchers will test 42 adults aged 18-80 before and after surgery using simple mental quizzes and blood tests for brain injury markers. The goal is to understa…

This study looks at whether doing lung reopening maneuvers several times during spine surgery (while lying face-down) helps keep the lungs open better than doing it just once. Sixty adults having elective spine surgery will be randomly assigned to one of two groups. Doctors will …

This study is testing whether a quick ultrasound scan before anesthesia can predict if a patient will have dangerously low blood pressure after going to sleep for brain surgery. Researchers will measure the size of a large vein and an artery in the belly. The goal is to find a si…

This study watches 100 adults having lung surgery to see if one type of anesthesia helps them wake up and recover faster. Patients get either IV or inhaled anesthesia as part of their normal care—no extra treatments are given. The goal is to learn which method might lead to quick…

This study looks at two different ways of setting the breathing machine (ventilator) during general anesthesia for children having dental work. The goal is to find out which setting helps children breathe better and recover more smoothly after the procedure. About 75 children age…

This study tests whether electronic stethoscopes can accurately monitor breathing in 30 adults during surgery under general anesthesia. The goal is to help anesthesiologists detect breathing problems early, like airway blockages or low breathing, to make surgery safer. Participan…
