Tight Versus Liberal Blood Glucose Control in Adult Critically Ill Patients

When blood glucose exceeds the preset target, insulin will be administered through continuous intravenous infusion. Insulin will be titrated according to frequent measurement of blood glucose and with use of the LOGIC-insulin algorithm in the experimental group. The intervention will be stopped upon ICU discharge, or until the patient is able to resume oral feeding, or until the patient no longer has a central venous catheter, whatever comes first.
