Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Number of Patients with Hypotensive Events in comparison between both groups | During induction and maintainance of general anaesthesia (average estimated time = 3 hours) |
| Dosage of Norepinephrine given to the patient to maintain blood pressure normotensive | During induction and maintainance of general anaesthesia (average estimated time = 3 hours) |
Secondary
| Measure | Time frame |
|---|---|
| Incidence of acute kidney failure postoperatively | during hospital stay after surgical procedure (in average 3 days) |
Other
| Measure | Time frame |
|---|---|
| mean arterial blood pressure | consecutive full hours of general anaesthesia (estimated average 3 hours) |
