Brief Summary
Craniotomy presents true anesthetic challenges, mainly due to the need to optimize cerebral perfusion, facilitate brain relaxation, achieve rapid emergence for neurologic assessment, and minimize perioperative complications.

Study Arms (3)
Dexmedetomidine group
ACTIVE COMPARATORIntravenous loading dose of dexmedetomidine 1 µg/kg over 10 minutes before propofol infusion, followed by an intraoperative maintenance infusion of 0.5 µg/kg/hour.
Fentanyl group
ACTIVE COMPARATORIntravenous loading dose of fentanyl 1 µg/kg over 10 minutes before propofol infusion, followed by an intraoperative maintenance infusion of 0.5 µg/kg/hour.
Magnesium group
ACTIVE COMPARATORMagnesium sulphate 30-50 mg/kg intravenous over 15-30 minutes before propofol infusion, followed by intraoperative maintenance infusion of 10-20 mg/kg/hour.
