Reliability of arterial, capillary and venous point-of-care glucose measurements in the intensive care unit setting: evaluation of two glucometers

Increased risk of hypoglycemia is the major drawback of strict glycemic control, which has been extensively used in critically ill patients. Fast and precise glucose measurements are therefore mandatory. Our aim was to evaluate the accuracy of two methods of bedside point-of-care testing for glucose measurements using arterial, capillary and venous blood samples in ICU patients.
