Accuracy and Reliability of Continuous Glucose Monitoring in the Intensive Care Unit: A Head-to-Head Comparison of Two Subcutaneous Glucose Sensors in Cardiac Surgery Patients

摘要: Hyperglycemia, hypoglycemia, and glucose variability are common during intensive care unit (ICU) stay associated with increased mortality (1–3). Continuous monitoring (CGM) is a promising tool to assist control, but the accuracy reliability of these devices in critically ill patients uncertain (4,5). Therefore, we studied two different CGM postoperatively cardiac surgery an investigator-initiated trial. We placed (Guardian RT, Medtronic Minimed; FreeStyle Navigator, Abbott Diabetes Care) subcutaneously abdominal wall before 60 patients. This first time Navigator has been ICU setting. Both were calibrated simultaneously upon arrival at after surgery. Further calibrations performed according manufacturers’ instructions. An arterial blood value was measured AccuChek device (Performa II, …
