NCT04963036

Brief Summary

The aim of this study is to determine if Nociception Level (NOL)-guided Remifentanil analgesia, combined with Entropy-guided Propofol anesthesia, has a significant beneficial effect on the incidence of intraoperative hypotension episodes and/or on vasopressor requirements, during long-lasting major surgeries for high risk patients. The investigator will also investigate the effects of guided anesthesia on postoperative Myocardial Injury in Non-cardiac Surgery (MINS) and Postoperative cognitive dysfunction (POCD), amongst other frequent postoperative complications, in this population.

Outcome Measures

Primary Outcomes (4)

  • Occurrence of intraoperative hypotension

    Occurrence of intraoperative hypotension is defined by at least 1 minute under the hypotension thresholds. Moderate and Severe Hypotension are respectively defined as a Mean Blood Pressure \<65 mmHg or \<55 mmHg and \<75 or \<65 mmHg for patient with history of chronic hypertension

    during surgery

  • Total Vasopressor Dose

    Total Vasopressor Dose used throughout the intervention to maintain Arterial Pressure within a pre-defined individualized ranges (≥ 65 mmHg or ≥75 mmHg for patient with history of chronic hypertension, and ≤ 100 mmHg)

    during surgery

  • Number of interventions to cure intraoperative hypotension

    Number of vasopressor boli or vasopressor infusion dose adjustments

    during surgery

  • Total Time under hypotension thresholds

    Hypotension Thresholds ( \<65 mmHg or \< 75mmHg for patient with history of chronic hypertension)

    during surgery

Secondary Outcomes (10)

  • Myocardial Injury in Non-Cardiac Surgery (MINS) marker (Troponin T)

    up to 48 hours after surgery

  • Postoperative Acute Kidney Injury (AKI) marker (creatinin/Glomerular Filtration Rate)

    up to 48 hours after surgery

  • Postoperative Cognitive Decline (POCD)

    up to 6 months after surgery

  • PostOperative Delirium (PO Delirium)

    up to 6 months after surgery

  • Dosage of Stress Hormones

    up to 4 hours after surgery

  • +5 more secondary outcomes

Entropy and NOL-Guided Goal Directed Anesthesia

EXPERIMENTAL
Other: Entropy and NOL-Guided Goal Directed Anesthesia

Standard of Care Group (Entropy and blinded NOL)

ACTIVE COMPARATOR
Other: Standard of Care Group (Entropy and blinded NOL)

Interventions

Entropy-guided Anesthesia (Propofol infusion in order to maintain Entropy between 45 and 55) and NOL-guided Analgesia (Remifentanil infusion in order to maintain NOL-Index between 10 and 25).

Entropy and NOL-Guided Goal Directed Anesthesia

Entropy-guided Anesthesia (Propofol infusion in order to obtain Entropy between 45 and 55) and Remifentanil infusion at the discretion of the anesthetist in charge, based on current practice: patient vitals (Heart Rate, Blood Pressure, Respiratory Rate…), movements, spontaneous breathing, experience.... In this group, nociception monitor screen will be concealed and the NOL index will not be available for guidance of remifentanil dosing).
