Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The difference in median glucose 1 hour after surgery will be calculated as a measure of glycaemic control during surgery. Furthermore, the difference in proportion of time spent in the target range, time spent above the target range and time spent below the target range between groups will be calculated. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary outcome measure include the accuracy of the GCM, measured by the mean absolute relative difference (MARD= (CGM value−POC/POC)). Furthermore a Clarke error grid and Bland-Altman analyses, MARD in the lower glycaemic (glucose 10 mmol/l) ranges. The ranges are according to the AMC protocol. The MARD during cardiopulmonary bypass and during the use of vasopressors will also be calculated. We will record the number of false alarms, the number of times the intravenous line has to be replaced due to failure of the device or clotting error. Also, the glucose variability, the amount of insulin used and the occurrence hypoglycaemic events (glucose < 4.0 mmol/l) and severe hypoglycaemia (glucose <2.3 mmol/l) will be compared between groups. Glucose variability will be expressed as mean absolute glucose change (MAG) per hour18. The difference in occurrence of postoperative complications will be assessed according to Dindo-Clavien grading system19 30 days after surgery. | — |
