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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Brain relaxation
Time Frame: 2hours
  1. Tight Brain-the brain surface is jutting out or expanding beyond the craniotomy margins, brain pulsations are not clearly defined.
  2. Brain surface at level of craniotomy margins, Brain pulsations faintly observed
  3. Brain surface just below the surface of craniotomy margin. Brain pulsations well seen.
  4. Brain surface well below the surface of craniotomy margin, well retracted in to the cranial cavity with good brain pulsations.Brain relaxation score will me measured only once. There is no follow up
2hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Hemodynamic Measurement-Heartrate
Time Frame: 2hours
The change in hemodynamic variable heart rate in beats per minute will be measured through the study period
2hours
Hemodynamic Measurement-Bloodpressure
Time Frame: 2hours
The change in hemodynamic variable blood pressure in mmHg will be measured through the study period
2hours
