Brief Summary

Critically ill patients usually develop hyperglycemia, which is associated with an increased risk of morbidity and mortality. Controversy exists on whether targeting normal blood glucose concentrations with insulin therapy, referred to as tight blood glucose control (TGC) improves outcome of these patients, as compared to tolerating hyperglycemia. It remains unknown whether TGC, when applied with optimal tools to avoid hypoglycemia, is beneficial in a context of withholding early parenteral nutrition. The TGC-fast study hypothesizes that TGC is beneficial in adult critically ill patients not receiving early parenteral nutrition, as compared to tolerating hyperglycemia.

Study Arms (2)

Tight glucose control

EXPERIMENTAL

Target normal fasting blood glucose concentrations (80-110 mg/dl) with insulin therapy, administered through continuous intravenous infusion.

Drug: Insulin

Liberal glucose control

ACTIVE COMPARATOR

Tolerate hyperglycemia up to 215 mg/dl. In patients requiring insulin therapy, insulin will be titrated to target blood glucose concentrations between 180 and 215 mg/dl.

Drug: Insulin

Interventions

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.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:
