Brief summary
The debate about tight glycemic control (TGC) in the operating room and on the intensive care unit is ongoing, especially in cardio-surgical patients treated with blood cardioplegia, due to high blood glucose levels during operations and subsequent high rates of sternal wound infections. We showed in a feasibility study that early computer based insulin therapy starting in the operating room is a safe therapy that allows to better warrant normoglycemia in patients undergoing major cardiac surgery with the use of blood cardioplegia.
Detailed description
Patients are enrolled and randomized into 3 groups. Start of therapy is determined as the beginning of cardiopulmonary bypass. Group A: Therapy with computer-based algorithm and measurement of blood glucose every 30 min. Group B: Measurement of blood glucose every 15 min using the identical computer-based algorithm. Group C: Conventional therapy using a fixed insulin dosing scheme. End of therapy is defined as discharge from ICU.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Time within a blood glucose corridor of 80 - 150 mg/dl | From start of cardiopulmonary bypass during surgery until discharge from ICU, which is approximately after 48 -72 hrs. | The primary endpoint was defined as the time within a given blood glucose corridor from 80 - 150 mg/dl during therapy |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Hypoglycemic events | From beginning of cardiopulmonary bypass during surgery until discharge from the ICU, which is approximately after 48-72 hrs. | Secondary endpoints were the number of hypoglycemic events defined as blood glucose levels under 80 mg/dl |
