Continuous interstitial glucose monitoring in diabetic and non-diabetic critically ill patients is simple and accurate: comparison with venous, arterial and capillary glucose measurements.

ABSTRACT:

Introduction

To reduce mortality, thigh glycemic control is recommended in critically ill patients due to their extreme glycemic variability. Continuous glucose monitoring (CGM) devices allows frequent determination of blood glucose levels; however, conflicting results have been reported from studies assessing their accuracy in critically ill patients. Aim of this study was to assess the repeatability and the analytical and clinical accuracy of FreeStyle Libre 2 (FSL-)CGM.

Materials and methods

Prospective single-center observational study enrolling 40 critically ill patients. For four consecutive days, we measured three consecutive interstitial FSL-CGM-derived glucose levels, along with one arterial and venous blood gas analysis and a capillary-derived blood glucose level,
