Effects of anesthetics on brain connectivity in glioma patients

The Alterations of Brain Network Connectivity Under Sedation and Anesthesia in Patients With Supratentorial Glioma

Observational Beijing Tiantan Hospital · NCT06138340

This study tests how different types of anesthesia affect brain connections in patients having surgery for a brain tumor to see if it impacts their thinking and recovery afterward.

What this trial studies

This observational study investigates how different anesthetics, specifically dexmedetomidine, propofol, and remimazolam, influence brain network connectivity in patients undergoing surgery for unilateral supratentorial glioma. By utilizing advanced neuroimaging techniques, the study aims to uncover the mechanisms behind postoperative cognitive function and the incidence of delirium. The research focuses on patients aged 18 and older who are right-handed and meet specific health criteria, ensuring a controlled environment for analysis.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old diagnosed with unilateral supratentorial glioma who are right-handed and in good health.

Not a fit: Patients with a history of cerebrovascular disease, brain trauma, or those with severe cardiac or renal dysfunction may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved anesthetic protocols that minimize cognitive impairment and delirium in brain tumor patients post-surgery.

How similar studies have performed: Previous studies have indicated that dexmedetomidine may reduce postoperative delirium, suggesting that this approach has potential based on earlier findings.
