Arms	Assigned Interventions
Matias protocol: Active Comparator A protocol based on the absolute glucose value - Matias protocol (Matias)	Drug: insulin Insulin was was administered according to each protocol rules/suggestions into a central venous line as a continuous infusion (Bath and eMPC protocols) or as a combination of a continuous infusion and boluses (Matias protocol). A standard concentration of 50 IU of insulin in 50 ml of 0.9% NaCl was used. In all patients, infusion of 10% glucose solution was initiated upon admission to ICU with glucose dose of 2.5 g/kg of ideal body weight (height in centimetres minus 100) per hour and lasted for 18 hours, when normal oral food intake was started. In ventilated patients, the glucose infusion lasted for 48 hours, and then standard enteral nutrition was initiated.
Bath protocol: Active Comparator A protocol based on the relative glucose change - Bath protocol (Bath)	Drug: insulin Insulin was was administered according to each protocol rules/suggestions into a central venous line as a continuous infusion (Bath and eMPC protocols) or as a combination of a continuous infusion and boluses (Matias protocol). A standard concentration of 50 IU of insulin in 50 ml of 0.9% NaCl was used. In all patients, infusion of 10% glucose solution was initiated upon admission to ICU with glucose dose of 2.5 g/kg of ideal body weight (height in centimetres minus 100) per hour and lasted for 18 hours, when normal oral food intake was started. In ventilated patients, the glucose infusion lasted for 48 hours, and then standard enteral nutrition was initiated.
eMPC: Active Comparator a computer-based model predictive control algorithm with variable sampling rate (eMPC)	Drug: insulin Insulin was was administered according to each protocol rules/suggestions into a central venous line as a continuous infusion (Bath and eMPC protocols) or as a combination of a continuous infusion and boluses (Matias protocol). A standard concentration of 50 IU of insulin in 50 ml of 0.9% NaCl was used. In all patients, infusion of 10% glucose solution was initiated upon admission to ICU with glucose dose of 2.5 g/kg of ideal body weight (height in centimetres minus 100) per hour and lasted for 18 hours, when normal oral food intake was started. In ventilated patients, the glucose infusion lasted for 48 hours, and then standard enteral nutrition was initiated.

Detailed Description:

120 consecutive post-cardiac surgery patients randomized to the three protocols with a target glycemia range from 4.4 to 6.1 mmol/l. Intravenous insulin was administered continuously or in combination with insulin boluses (Matias protocol). Blood glucose was measured in 1-4 hour intervals as requested by protocols.
