Core Tip
Core Tip: Propofol is widely preferred for the induction and maintenance in neuroanesthesia due to its neuroprotective properties. However, propofol frequently causes hypotension during the induction of anesthesia in neurosurgical patients, which may compromise cerebral perfusion. Therefore, combining phenylephrine with propofol significantly reduces induction-related hypotension, minimizes vasopressor requirement, and maintains stable intraoperative hemodynamics without affecting brain relaxation, offering a practical approach for neuroanesthesia in glioma surgery.
