Closed-Loop Control of Vasopressor Administration in Patients Undergoing Cardiac Revascularization Surgery

INTRAOPERATIVE hypotension and arterial pressure variability have been shown to affect patient outcomes negatively, increasing the risk of stroke, kidney injury, and myocardical injury, among other conditions.1-5 Vasopressors normally are used to correct hypotension rapidly. Vasopressor infusions typically are administered by standard infusion pump, with the rate adjusted by bedside providers to reach a predefined target mean arterial pressure (MAP); this requires frequent changes in the infusion rate because of the almost constantly changing hemodynamic status of such patients.
