Supratentorial Masses: Anesthetic Considerations
Brain tumors constitute the majority of neurosurgical pathology that presents for surgery. Tumors vary from benign meningiomas to the aggressive malignant gliomas. Eighty percent of brain tumors are located in the supratentorial fossa, the remaining 20% are located in the posterior fossa.
Neurosurgical anesthesia is a delicate balance between providing adequate cerebral perfusion and optimizing surgical conditions while compensating for underlying neuropathology. Thorough understanding of neurological physiology and how it is affected by anesthetic techniques are imperative for the safe and effective care of the neurosurgical patient.
