However, the accuracy of these meters has not been evaluated in detail for these patients.


POCT blood glucose meters are already used in some hospitals for glucose measurements in patients during general anesthesia, with the assumption that the results are comparable to laboratory methods. POCT BG meters have the advantage that they are easy to use and show results in a very short time frame. Laboratory methods, however, take more time and results can be delayed. In general, laboratory methods are more accurate and so far, only one blood glucose POCT meter has been shown to produce equivalent results to a laboratory method. We therefore focus on arterial measurements in this study.

Arterial measurements are less disturbed by skin temperature and peripheral circulation. Controlled capillary measurements depend on a lot of different factors which are not constant during general anesthesia. This can also affect capillary blood sampling, which may result in a lower glucose concentration. Furthermore, fluid shifts during surgery are common due to blood loss, fluid administrations, and vasodilatory effect of anesthetics. General anesthesia often induces hypotension, which can cause reduction of perfusion and thereby a reduction of blood refreshing, leading to less accurate capillary blood glucose measurement compared to the actual value in the systemic circulation. BG concentrations can be measured by several methods, including point-of-care test (POCT) BG meters and laboratory methods. Hypoglycemia and hyperglycemia are unwanted conditions perioperatively, with BG concentrations between 4 and 12 mmol/L recommended by most guidelines. Blood glucose (BG) monitoring in diabetic patients during general anesthesia is important.
