  Purpose
Hyperglycemia is common in critically ill patients and associated with an adverse outcome. Thus, glycaemic control is an important issue in critical care. Despite extensive efforts of the intensive care unit staff difficulties were experienced in achieving efficient and safe glucose control. A fully automated algorithm may help to overcome some of these limitations by excluding intuitive interventions and integrating relevant clinical data in the decision-making process. Space GlucoseControl (TGC system) is a decision support system which helps to achieve safe and reliable blood glucose control in the desired ranges. Information on parenteral and enteral nutrition is automatically integrated into the calculations. The primary objective of the current study is to investigate the performance and usability of the Space TGC system for glucose control over an extended glucose control range (4.4 to 8.3 mmol/L) in postoperative cardiac surgery patients.

Primary Outcome Measures:
  • (arterial) blood glucose values -> percentage of time within predefined glucose target range 4.4-8.3 mmol/dL [ Time Frame: all blood glucose measurements from start of treatment until last glucose measurement under treatment (i.e. stop of intravenous insulin treatment) up to a maximum of 48h ]

Secondary Outcome Measures:
  • Hypoglycaemia ≤ 40 md/dL (2.2mM) [ Time Frame: all blood glucose measurements from start of treatment until last glucose measurement under treatment (i.e. stop of intravenous insulin treatment) up to a maximum of 48h ]
  • Usability parameters like convenience of alarming function; workload; blood sampling frequency [ Time Frame: all blood glucose measurements from start of treatment until last glucose measurement under treatment (i.e. stop of intravenous insulin treatment) up to a maximum of 48h ]
  • Concomitant medication including insulin infusion rate, parenteral/enteral nutrition [ Time Frame: all blood glucose measurements from start of treatment until last glucose measurement under treatment (i.e. stop of intravenous insulin treatment) up to a maximum of 48h ]
