Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess the effect of change in position from supine to lateral and supine to prone on cerebral oxygenation using NIRS during various positions (supine, prone, lateral) used during elective neurosurgery.Timepoint: Baseline NIRS reading will be taken in supine position from NIRS electrodes placed at the frontal area. NIRS reading will be taken at 5 minutes after induction of anesthesia. One minute before positioning the patient NIRS value will again be noted. Post final positioning of the patient, NIRS values will be recorded every minute till first 10 minutes, and then every 5 minutes till 30 minutes. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. To assess the significance and causes of changes in cerebral oxygenation during patient positioning in neurosurgery. 2. To assess changes in NIRS from awake state to anesthesia and positioning.Timepoint: Baseline NIRS reading will be taken in supine position from NIRS electrodes placed at the frontal area. NIRS reading will be taken at 5 minutes after induction of anesthesia. One minute before positioning the patient NIRS value will again be noted. Post final positioning of the patient, NIRS values will be recorded every minute till first 10 minutes, and then every 5 minutes till 30 minutes. | — |
