Further study details as provided by Charles University, Czech Republic:

Primary Outcome Measures:
  • Percentage of glycemic values in the A and B zone of Clarke Error Grid Analysis (a tool for assessing the accuracy of glucose meters) [ Time Frame: first 24 hours after cardiac surgery ]

Secondary Outcome Measures:
  • Entire study average glycemia level; time within, above and below the target range throughout the whole study period and after reaching the target range [ Time Frame: first 24 hours after cardiac surgery ]

Enrollment: 24
Study Start Date: September 2008
Primary Completion Date: August 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: CGM-eMPC Device: Continuous glucose monitoring system combined with enhanced model predictive control algorithm for intensive insulin treatment
Glucose measured with a real-time continuous glucose monitoring system served as an input for the enhanced model predictive control algorithm adjusting insulin infusion every 15 minutes for the first 24 hours after elective cardiac surgery
Control Other: Intensive insulin therapy using standard protocol
Insulin dosage according to the standard protocol for intensive insulin delivery used at Department of Cardiothoracic Surgery, General University Hospital, Prague.
