Blood glucose measurements in arterial blood of intensive care unit patients submitted to tight glycemic control: agreement between bedside tests.

Background: Implementing tight glycemic control (TGC) in intensive care unit (ICU) patients requires accurate blood glucose (BG) monitoring. We evaluated the performance of two commercially available bedside glucometers, Accu-Chek and HemoCue, in patients admitted to the ICU and in whom TGC was applied.

Methods: Thirty-seven adult ICU patients were prospectively included.
