Primary Outcome Measures

Name	Time	Method
Change of cerebral tissue oxygen saturation of patients with hypotension after anaesthesia induction. Calculated using low frequency haemoglobin oscillations measured using near infrared spectroscopy[Before induction, After induction, After intubation, At 5 minutes after induction, At 10 minutes after induction, At 15 minutes after induction (primary outcome).]

Secondary Outcome Measures

Name	Time	Method
Change in blood pressure during anaesthesia induction. We are using an automatic sphygmomanometer[Before induction<br>After induction<br>After intubation<br>At 5 minutes after induction<br>At 10 minutes after induction<br>At 15 minutes after induction]
