 Tight glycemic control with intensive insulin therapy dramatically reduces in-hospital mortality and adverse outcome but with a significant risk of hypoglycaemia. Intensive discontinuous blood glucose control may be insufficient to adapt insulin doses to reach ambitious glycemia targets in safety. Therefore new tools are needed for glucose monitoring in diabetic patients admitted in surgery intensive care units ICU. The mini-invasive continuous interstitial glucose monitoring device Glucoday Menarini Diagnostics has been recently developed and allows to access continuous interstitial glucose monitoring with real time record display.
