Deiberato, Rodrigo Octavio. Cavalcanti, Alexandre Biasi. Publication date: May 20, Introduction: Current guidelines and consensus recommend arterial and venous samples as equally acceptable for blood glucose assessment in point-of-care devices, but there is limited evidence to support this recommendation.
We evaluated the accuracy of two devices for bedside point-of-care blood glucose measurements using arterial, fingerstick and catheter venous blood samples in ICU patients, and assessed which factors could impair their accuracy. Methods: patients from a bed adult mixed-ICU, in a tertiary care hospital were prospectively enrolled.
Fingerstick, central venous catheter and arterial blood indwelling catheter samples were simultaneously collected, once per patient. Arterial measurements obtained with Precision PCx, and arterial, fingerstick and venous measurements obtained with Accu-chek Advantage II were compared to arterial central lab measurements.
Agreement between point-of-care and laboratory measurements were evaluated with Bland-Altman, and multiple linear regression models were used to investigate interference of associated factors. Results: Mean difference between Accu-chek arterial samples versus central lab was Accu-chek fingerstick versus central lab arterial samples presented a similar bias Agreement between venous samples with arterial central lab was the poorest mean bias Hyperglycemia, low hematocrit, and acidosis were associated with larger differences between arterial and venous blood measurements with the two glucometers and central lab.
