Awake Craniotomy without Invasive Blood Pressure Monitoring.

Objective: To assess the safety of foregoing invasive monitoring in a select group of patients undergoing awake craniotomy for supratentorial tumor resection.

Methods: Awake craniotomies were performed for tumor resection without invasive blood pressure monitoring when there was no preexisting cardiopulmonary indication as determined by the attending anesthesiologist according to institutional protocol. Noninvasive monitoring was performed every 3-5 minutes intraoperatively and then every 15 minutes in the recovery room for 4 hours before transfer to the ward.
