Changes of Cerebral Oxygenation During Anesthesia Induction

Completed

• Conditions: Cerebral Oxygen Saturation
• Interventions: Drug: 100% Oxygen

• Registration Number: NCT02687334
• Lead Sponsor: China Medical University, China

Brief Summary

The aim of this study was to investigate the changes of cerebral oxygen saturation (rSO2) during anesthesia induction.

Detailed Description

The aim of this study was to investigate the relationship between the cerebral oxygen saturation (rSO2) and pressure of carbon dioxide (PaCO2) and oxygen (PaO2) in arterial blood and to identify the covariates between rSO2 and PaCO2 and PaO2 during the period of anesthesia induction.
