NCT03136614

Brief Summary

Conditions

Outcome Measures

Primary Outcomes (3)

  • Number and degree of hypotensive episodes predicted by preoperative values of pulse wave velocity.

    The investigators will examine if high values of pulse wave velocity correlate with the frequency and severity of hypotensive episodes under anaesthesia.

    One year

  • Correlation between systemic vascular resistance and aortic augmentation index

    One year

  • Identity of cardiac output given by the PiCCO monitor and cardiac output given by the Arteriograph

    One year

Study Arms (3)

Preoperative

ACTIVE COMPARATOR

A single measurement with an Arteriograph is performed a day before an elective surgical intervention.

Device: Arteriograph

Intraoperative

ACTIVE COMPARATOR

An arteriograph is put on the patient for the time of operation. The device is set to measure in every 5 minutes.

Device: Arteriograph

Intensive Care Unit

ACTIVE COMPARATOR

Three separate measurements are performed on the subject with an Arteriograph throughout every dayshift for 3 days.

Device: Arteriograph

Interventions

Intensive Care UnitIntraoperativePreoperative
