All three are commonly used for general anesthesia, but they work in different ways. Ciprofol and propofol are given through a vein. Sevoflurane is breathed in as a gas. After brain tumor surgery, some older adults may develop sudden confusion and memory problems called delirium. Researchers want to learn which of these three medicines is best at preventing delirium and protecting brain function in older adults undergoing brain tumor surgery.\n\nAbout 381 participants aged 65 to 90 will take part. Participants will be randomly assigned to one of three groups. One group will receive ciprofol. Another group will receive propofol. The third group will receive sevoflurane. All participants will receive standard care during and after brain tumor removal.\n\nThe main goal is to compare how many participants develop delirium within 7 days after surgery. Researchers will also look at how long delirium lasts, how severe it is, thinking and memory skills at 7, 30, 90, and 180 days after surgery, quality of recovery, blood pressure and heart rate during surgery, and treatment safety.\n\nBlood tests will be used to measure markers of body stress, inflammation, and nerve cell injury before surgery, 3 hours after surgery, and 1 day after surgery. Researchers will also test thinking and memory with simple questions twice a day for 7 days after surgery. Later follow-up will be done by phone at 30, 90, and 180 days after surgery.\n\nThis study is designed to explore which anesthesia medicine is safest and best at protecting the brain after surgery in older adults with brain tumors.
