Abstract
Study objective
We hypothesize that personalized perioperative blood pressure management maintaining intraoperative mean arterial pressure (MAP) above the preoperative mean nighttime MAP reduces perfusion-related organ injury compared to maintaining intraoperative MAP above 65 mmHg in patients having major non-cardiac surgery. Before testing this hypothesis in a large-scale trial, we performed this bicentric pilot trial to determine a) if performing preoperative automated nighttime blood pressure monitoring to calculate personalized intraoperative MAP targets is feasible; b) in what proportion of patients the preoperative mean nighttime MAP clinically meaningfully differs from a MAP of 65 mmHg; and c) if maintaining intraoperative MAP above the preoperative mean nighttime MAP is feasible in patients having major non-cardiac surgery.
Design
Bicentric pilot randomized trial.
Setting
University Medical Center Hamburg-Eppendorf, Hamburg, Germany, and RWTH Aachen University Hospital, Aachen, Germany.
Patients
Patients ≥ 45 years old having major non-cardiac surgery.
Interventions
Personalized blood pressure management.
Measurements
Proportion of patients in whom preoperative automated nighttime blood pressure monitoring was possible; proportion of patients in whom the preoperative mean nighttime MAP clinically meaningfully differed from a MAP of 65 mmHg (difference > ±10 mmHg); intraoperative time-weighted average MAP below the preoperative mean nighttime MAP.
Main results
We enrolled 105 patients and randomized 98 patients. In 98 patients (93 %), preoperative automated nighttime blood pressure monitoring was possible. In 83 patients (85 %), the preoperative mean nighttime MAP clinically meaningfully differed from a MAP of 65 mmHg. The median time-weighted average MAP below the preoperative mean nighttime MAP was 3.29 (1.64, 6.82) mmHg in patients assigned to personalized blood pressure management.
Conclusions
It seems feasible to determine the effect of personalized perioperative blood pressure management maintaining intraoperative MAP above the preoperative mean nighttime MAP on postoperative complications in a large multicenter trial.
期刊介绍:
The Journal of Clinical Anesthesia (JCA) addresses all aspects of anesthesia practice, including anesthetic administration, pharmacokinetics, preoperative and postoperative considerations, coexisting disease and other complicating factors, cost issues, and similar concerns anesthesiologists contend with daily. Exceptionally high standards of presentation and accuracy are maintained.
The core of the journal is original contributions on subjects relevant to clinical practice, and rigorously peer-reviewed. Highly respected international experts have joined together to form the Editorial Board, sharing their years of experience and clinical expertise. Specialized section editors cover the various subspecialties within the field. To keep your practical clinical skills current, the journal bridges the gap between the laboratory and the clinical practice of anesthesiology and critical care to clarify how new insights can improve daily practice.
