ClinConnect Summary
This clinical trial is investigating how different anesthetics, specifically dexmedetomidine and propofol, affect brain connections in patients undergoing surgery for a type of brain tumor called supratentorial glioma. Researchers want to understand how these anesthetics may influence cognitive function after surgery, particularly looking at the risk of postoperative delirium, which is a type of confusion that can happen after surgery. By using advanced brain imaging techniques, the study aims to explore changes in brain networks during anesthesia and how these changes relate to thinking and memory.
To participate in this trial, individuals must be at least 18 years old, diagnosed with a unilateral supratentorial glioma confirmed by an MRI, and generally healthy (classified as ASA I-II, which means they have a low risk for surgery). However, those with certain medical histories, such as past brain surgeries, mental health issues, or severe heart problems, cannot take part. Participants can expect to undergo surgery with one of the anesthetics being studied and have their brain activity monitored through imaging to help researchers learn more about the impact of anesthesia on brain function. This research could lead to better ways to manage patient care during and after brain surgery.
