NCT04894045

Brief Summary

The investigators propose a pilot trial to (1) proof the concept that defining the intraoperative mean arterial pressure (MAP) intervention threshold based on the mean nighttime MAP (assessed using preoperative automated blood pressure monitoring) results in clinically relevant (mean nighttime MAP ± 10 mmHg) different target values compared with using an absolute population-derived MAP intervention threshold of 65 mmHg (primary endpoint); (2) investigate if a personalized perioperative blood pressure management is feasibly in multi-center studies, especially if the target values can be sufficiently achieved (secondary endpoint); (3) study the impact of personalized perioperative blood pressure management on the incidence of myocardial injury after non-cardiac surgery (MINS) (exploratory endpoint); (4) study the impact of personalized perioperative blood pressure management on the incidence of acute kidney injury within the first three postoperative days according to the KDIGO (Kidney Disease: Improving Global Outcomes) definition without oliguric criteria (exploratory endpoint).

Outcome Measures

Primary Outcomes (1)

  • Individualized MAP target value

    Difference between intraoperative target MAP (defined as the mean nighttime MAP assessed using preoperative automated blood pressure monitoring) and 65 mmHg; we consider a difference \> ± 10 mmHg as clinically meaningful.

    1 day before surgery

Secondary Outcomes (2)

  • Proportion of patients with calculated MAP target

    day of surgery

  • Duration and severity of MAP below MAP target

    day of surgery

Other Outcomes (2)

  • Incidence of myocardial injury after non-cardiac surgery

    baseline, postoperative days 1, 2 and 3

  • Incidence of acute kidney injury

    baseline, postoperative day 1, 2 and 3

Study Arms (2)

Personalized management group

OTHER

Intraoperative MAP will be maintained at least at the mean nighttime MAP (assessed using preoperative automated blood pressure monitoring). If the mean nighttime MAP is below 65 mmHg, intraoperative MAP will be maintained at least at 65 mmHg.

Other: Personalized management

Control group

NO INTERVENTION

Routine intraoperative blood pressure management with a lower intervention threshold of 65 mmHg. In contrast to the patients in the personalized management group, the individual mean nighttime MAP assessed using preoperative automated blood pressure monitoring is not taken into account and the treating anesthesiologists are blinded to the data of preoperative automated blood pressure monitoring.

Interventions

Intraoperative MAP will be maintained at least at the mean nighttime MAP (assessed using preoperative automated blood pressure monitoring). If the mean nighttime MAP is below 65 mmHg, intraoperative MAP will be maintained at least at 65 mmHg.
