Effect of blood-sugar limitation on intensive care mortality: Intragroup evaluation.

Objective: To evaluate the safety profile of blood sugar limits in intensive care unit (ICU) patients.

Methods: Adult patients with ICU stay >36 h, more than two blood sugar measurements and antibiotic therapy concordant with locally adapted guidelines were included. For analyses, one study cohort was defined in two ways: as a narrow group, euglycaemic patients' blood sugar levels 80-150 mg/dl; as a moderate group, euglycaemic patients' blood sugar levels 80-180 mg/dl.
