Impact of Continuous Non-invasive Blood Pressure Monitoring on Hypotension in Patients Having Non-cardiac Surgery

October 11, 2021 updated by: Universitätsklinikum Hamburg-Eppendorf

The Impact of Continuous Non-invasive Blood Pressure Monitoring on Post-induction and Intraoperative Hypotension in Patients Having Non-cardiac Surgery (DETECT Trial): A Randomized Trial

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.

Design Details

  • Primary Purpose: PREVENTION
  • Allocation: RANDOMIZED
  • Interventional Model: PARALLEL
  • Masking: SINGLE

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: Continuous monitoring group
Device: Continuous 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.
ACTIVE_COMPARATOR: Intermittent monitoring group
Device: Intermittent 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.
