Although compelling evidence supports this strategy in postoperative patients who have undergone cardiac surgery the use of tight glucose control has been challenged in other situations including in medical critically ill patients and in those who have undergone non-cardiac surgery. Similarly the mechanisms that underlie the effects of high-dose insulin are not fully elucidated. These arguments emphasize the need to study the effects of tight glucose control in a large heterogeneous cohort of intensive care unit patients. Keywords cardiac surgery critically ill hyperglycemia insulin metabolism Until the end of the past millenium relatively little attention was given to control of blood sugar levels. In critically ill patients hyperglycaemia was considered to be physiological because it results from the metabolic and hormonal changes that accompany the stress response to injury. In most intensive care units ICUs blood sugar was checked every 4-6 hours and hyperglycaemia defined as blood sugar levels 10-12 mmol l 180-216 mg dl was corrected by subcutaneous or intravenous insulin. The presence of pre-existing diabetes mellitus or post-neurosurgical status often
