Is an intraoperative MAP less than 55 mmHg associated with AKI and myocardial injury in patients undergoing noncardiac surgery?
Patients undergoing noncardiac surgery
Intraoperative mean arterial pressure (MAP) less than 55 mmHg
Acute kidney injury (AKI) and myocardial injuryhard clinical
Maintaining intraoperative MAP above 55 mmHg during noncardiac surgery may be important to prevent acute kidney injury and myocardial injury, though randomized trials are needed.
Even short durations of an intraoperative MAP less than 55 mmHg are associated with AKI and myocardial injury. Randomized trials are required to determine whether outcomes improve with interventions that maintain an intraoperative MAP of at least 55 mmHg.
