Craniotomy is performed for a variety of indications, including tumor resection, intracranial vascular procedures, evacuation of hematoma, and trauma.

This topic will discuss overall anesthetic management for craniotomy. (See "Anesthesia for patients with acute traumatic brain injury".)


History and physical examination — Evaluation before craniotomy should include the usual preanesthesia history and physical examination. Additional concerns specific to craniotomy include the following:

Neurologic status – The patient's baseline neurologic status, including current and prior specific deficits, signs and symptoms of increased intracranial pressure (ICP), and history of seizures should be assessed.

On emergence from anesthesia, new deficits may be cause for concern, while reappearance of prior deficits may represent differential emergence, and may resolve quickly. (See 'Differential emergence or awakening' below.)
