Brief summary

This is a randomized trial (1) investigating whether continuous non-invasive finger-cuff blood pressure monitoring reduces the area under a mean arterial pressure (MAP) of 65 mmHg within the first 15 minutes of anesthetic induction compared to intermittent blood pressure monitoring using upper-arm cuff oscillometry in patients having non-cardiac surgery; and (2) investigating whether continuous non-invasive finger-cuff blood pressure monitoring reduces the time-weighted average for MAP \<65 mmHg during the intraoperative period compared to intermittent blood pressure monitoring using upper-arm cuff oscillometry in patients having non-cardiac surgery.

Detailed description

Interventions

DEVICEContinuous non-invasive blood pressure monitoring

In patients randomized to the continuous monitoring group, continuous non-invasive finger-cuff blood pressure monitoring will be displayed on the patient monitor. The treating anesthesiologist will be blinded to intermittent blood pressure monitoring using upper-arm cuff oscillometry.

DEVICEIntermittent non-invasive blood pressure monitoring

In patients randomized to the intermittent monitoring group, intermittent blood pressure monitoring using upper-arm cuff oscillometry will be displayed on the patient monitor. The treating anesthesiologist is blinded to continuous non-invasive finger-cuff blood pressure monitoring.
