Evaluation of a continuous blood glucose monitoring system using a central venous catheter with an integrated microdialysis function

Abstract Introduction: Glycemic control in critically ill patients has been the topic of an interesting debate during the last decade. An accurate continuous glucose monitoring system is essential to better understand this field. This prospective study thus evaluates the accuracy and technical feasibility of a continuous glucose monitoring system using intravascular microdialysis. Patients and Methods: Thirty patients undergoing cardiac surgery were monitored using a triple-lumen central venous catheter (Eirus™ TLC; Eirus Medical AB, Solna, Sweden) with an integrated microdialysis function. The catheter functions as a central venous catheter, enabling blood sampling and administration of infusions and medication while simultaneously providing continuous glucose monitoring. The patients were monitored for up to 48 h postoperatively. As reference, arterial blood gas samples were taken every hour and analyzed in a blood gas analyzer. Results: Six hundred seven paired samples were obtained for analysis. Using...
