2026年6月1日 更新者:University Hospital, Basel, Switzerland

Feasibility and Clinical Implications of Real-time Cerebral Autoregulation Monitoring in Major Noncardiac Surgery With the Medtronic Cotrending Algorithm (AUTOREGULATE- NONCARDIAC-COTRENDING)

This study is to prospectively assess the feasibility and clinical implications of intraoperative real-time cAR monitoring using the Medtronic Cotrending algorithm.

研究概览

详细说明

Intraoperative hypotension during noncardiac surgery is strongly associated with postoperative organ injury. The AUTOREGULATE-NONCARDIAC study, a multicenter prospective cohort study and precision medicine platform is aiming to investigate the feasibility and clinical implications of different approaches of cerebral autoregulation (cAR) monitoring in high-risk patients undergoing major noncardiac surgery (ClinicalTrials.gov NCT05336864). A central shortcoming of the currently used gold standard methodology of cerebral autoregulation monitoring (COx [Cerebral Oximetry Index] methodology) is its necessity for extended periods of monitoring data with sufficient variability, its high failure rate in certain settings, e.g. in noncardiac surgery, and the requirement for expertise in evaluating the generated cerebral autoregulatory curves.

There is a need for novel approaches to cerebral autoregulation monitoring addressing the performance and usability issues of the COx methodology. One potentially promising algorithm is the Medtronic Cotrending algorithm, which in cardiac surgery has shown strong agreement with the COx methodology and provided rapid estimates of cAR state with high uptime and user-friendly visualization of autoregulatory status. However, the Medtronic Cotrending algorithm has never been tested in noncardiac surgery.

This substudy of AUTOREGULATE-NONCARDIAC aims to prospectively assess the feasibility and clinical implications of intraoperative real-time cAR monitoring using the Medtronic Cotrending algorithm.

Specifically, it will be determined:

  • Success rate of cerebral lower limit of autoregulation (cLLA) determination: proportion of patients in study cohort in whom cerebral autoregulatory parameters could be determined
  • Intraoperative uptime: percentage of intraoperative time during which presumed valid and actionable estimates of cerebral autoregulatory parameters were delivered
  • Time to first estimate of cerebral autoregulatory parameters: Elapsed intraoperative time to first presumed valid estimates of cerebral autoregulatory parameters
  • Sensitivity to external factors: Sensitivity of the algorithm to known confounders and determinants of cerebral autoregulatory function, e.g. changes in gas exchange, administration of vasopressors, skin pigmentation.
  • Sensitivity to data artefacts: Sensitivity of the algorithm to artefacts in data (e.g. in BP or rSO2 signals).
