Glycemic control in diabetic and non-diabetic cardiac surgical patients and length of hospital stay.

Background: Maintaining blood glucose levels (BGL) within normoglycemic range has been shown to reduce morbidity and mortality in critically ill patients. However, there is little evidence that maintenance of normoglycemic BGL is beneficial for diabetic and non-diabetic patients who undergo cardiac surgery.

Purpose: To examine the relationship between BGL and length of stay (LOS) of cardiac surgical patients.
