GENERAL ANESTHESIA

This study tests whether a targeted nerve block (sphenopalatine ganglion block) given before surgery can improve the surgeon's view and reduce pain after pituitary tumor removal. About 70 adults aged 21–60 will be randomly assigned to receive either the nerve block plus standard …

This study tests whether a small dose of caffeine placed under the tongue can help elderly patients (65 and older) wake up faster and feel less confused or agitated after general anesthesia. Fifty participants having eye surgery will receive either caffeine or a placebo. The goal…

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 collects information from hospitals across the U.S. to understand why some women receive general anesthesia during C-sections and how it affects their care. Researchers will look at factors like hospital type and policies to find patterns and improve safety. The study …

This study looks at two different muscle relaxant drugs used during general anesthesia in people with chronic kidney disease. The goal is to see which drug leads to fewer lung problems after surgery. About 490 adults with kidney disease will take part, and researchers will track …

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 see which setting helps kids breathe better and wake up more smoothly. About 75 children aged 2 to 12 will take part, and…

This study looks at whether bladder tumor surgery under general anesthesia causes short-term memory or thinking problems. Researchers will test 42 adults before and after surgery using simple cognitive tests and measure brain injury markers in the blood. The goal is to better und…

This study tests whether electronic stethoscopes can accurately monitor breath sounds in 30 adults undergoing general anesthesia for elective surgery. The goal is to help anesthesiologists detect breathing problems early, such as airway blockages or low breathing, to improve pati…

This study looks at whether the time it takes to deliver a baby during a planned C-section affects the baby's blood gas levels (pH and base excess). Researchers will compare two types of anesthesia (general vs. spinal) in 100 pregnant women. The goal is to understand how delivery…

This study is testing whether a simple ultrasound scan before brain surgery can predict if a patient's blood pressure will drop dangerously low after they receive anesthesia. Researchers will measure the size of two major blood vessels and see how well those measurements predict …

This study watches 100 adults having lung surgery to see how they recover from two common anesthesia methods: IV drugs or inhaled gas. No extra treatments are given—just standard care. The goal is to learn which approach leads to faster awakening and fewer complications, helping …

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 doing lung-opening maneuvers several times during spine surgery (instead of just once) can reduce partial lung collapse. About 60 adults having elective spine surgery while lying face-down will take part. Doctors will use lung ultrasound to check how w…
