Intermittent Versus Continuous Glucose Monitoring in Intensive Care Unit

Intravenous insulin therapy will be guided by interstitial glucose measurements using DexcomG7 continuous glucose monitor. Confirmatory blood glucose tests will be performed daily. In extreme clinical conditions (post-resuscitation, pH \< 7.20, severe hypoxia, severe haemodynamic compromise), confirmatory blood tests will be performed in 2 hour intervals until clinical improvement.

Intravenous insulin dosing will be guided according to blood glucose measurements using RadiometerABL800 (standard of care). DexcomG7 continuous glucose monitor will be applied in blinded mode for interstitial glucose monitoring for later CGM metrics and comparison analysis.
