Abstract
Background
Critical illness is still a major part of burden on healthcare systems and comprises about 7.6% of total in-hospital admissions1. Critically ill patients have different glucose metabolism due to stress related conditions, an entity labeled as stress hyperglycemia which is mainly attributed to release of counter regulatory hormones2,3. Stress hyperglycemia is found in both diabetic as well as non-diabetics moreover in non- diabetics4. Fasting blood sugar, postprandial blood sugar, HbA1c are important predictors of glycemic control. But these have limitations in critical set up and thus there is one more entity beyond these traditional markers i. e. glycemic variability (GV)3 which may be an important predictor of outcome in critically ill patients.
