What this trial studies

This study evaluates the effectiveness of adding low doses of ketamine or fentanyl to a combination of propofol and dexmedetomidine for total intravenous anesthesia in patients undergoing elective craniotomy for supratentorial brain tumors. The research focuses on various outcomes including brain relaxation scores, hemodynamic stability, surgeon satisfaction, and the total requirement of intraoperative propofol and postoperative analgesia. By comparing these combinations, the study aims to determine the optimal anesthesia approach for this specific surgical procedure.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-70 with a GCS of 14-15, ASA I-III, and a BMI of less than 35 scheduled for elective craniotomy.

Not a fit: Patients with severe comorbidities, uncontrolled hypertension, or allergies to the study drugs may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance anesthesia management, improve surgical conditions, and reduce postoperative pain for patients undergoing craniotomy.

How similar studies have performed: Other studies have shown promising results with similar anesthesia approaches, indicating potential for success in this trial.
