Heartrate Variability and Intraoperative Brain Conditions in Supratentorial Tumors
January 22, 2021 updated by: DyAnsys, Inc.
The Usefulness of the Combination of Preoperative Assessment of Optic Nerve Sheath Diameter and Heart Rate Variability to Predict Intraoperative Brain Condition in Patients With Supratentorial Tumors
This study aims to determine the relationship between heart rate variability and intraoperative brain relaxation conditions in patients with brain tumors.
