GENERAL ANESTHESIA

This study watches 60 adults having planned abdominal surgery under general anesthesia. Researchers will check eyelid reflexes, eye movements, and pupil size at three points during surgery to see if these signs match standard depth-of-anesthesia monitors. The goal is to find simp…

This study will observe 150 adults undergoing rapid sequence induction, a common emergency anesthesia technique, to measure pain using a special monitor called the Analgesia Nociception Index (ANI). Researchers want to see how pain levels change during the procedure and what comp…

This study will compare two common anesthetics, sevoflurane and desflurane, to see how they affect a pain-monitoring tool called the Analgesia Nociception Index (ANI) in 80 adults undergoing general anesthesia. Participants will be randomly assigned to receive one of the two drug…

This study will test two different breathing machine pressure levels (PEEP) in 60 adults having lower back surgery while lying face down. The goal is to see which setting helps keep lungs working better and maintains good oxygen levels during the operation. Researchers will measu…

This study aims to find the best dose of alfentanil, a pain medicine, when used with propofol to place a breathing tube (LMA) in children aged 7 to 12 having day surgery. About 40 children will take part, and researchers will adjust doses based on how well the tube goes in. The g…

This study will compare two ways of giving anesthesia during thyroid surgery: general anesthesia alone versus general anesthesia plus a neck block. The goal is to see which method leads to less inflammation and better recovery. About 60 adults having elective thyroid surgery will…

This study will enroll about 958 adults with severe stroke who need a procedure to remove a blood clot from a large brain artery. Researchers want to find out if putting patients fully asleep with general anesthesia or keeping them lightly sedated leads to better recovery and les…

This study compares two methods for placing a breathing tube in children having surgery: a video laryngoscope (camera) versus a direct laryngoscope (no camera). The goal is to see which method leads to successful tube placement on the first attempt. Over 5,500 children from multi…

This study looks at whether noise in the operating room affects how deeply patients are asleep during surgery and their heart rate and blood pressure. Researchers will measure noise levels and compare them to standard monitoring data from 70 adults having planned surgery under ge…

This study will observe 34 adults undergoing long surgeries to collect data from advanced lung monitors. The goal is to see if these monitors can help doctors set breathing machines more safely, potentially reducing lung injuries after surgery. No new treatments are tested; the s…
