A team from the Institute for Clinical and Experimental Medicine (IKEM) and the First and Third Faculty of Medicine at Charles University, in collaboration with U.S. researchers, investigated the feasibility of accurate continuous blood glucose monitoring in intensive care unit (ICU) patients following major surgeries.

The study involved 61 patients who underwent complex surgeries and transplantations and remained in the ICU postoperatively. A special Dexcom G6 sensor, placed below the clavicle, was used to monitor real-time glucose levels. The measured values were compared with traditional laboratory blood tests and standard hospital glucose monitoring devices.

The results showed that the modern sensor can reliably and accurately track blood glucose levels. In 92.8% of cases, the readings fell within the zone of highest clinical accuracy. The unconventional placement of the sensor beneath the clavicle proved suitable and may significantly improve the care of critically ill patients in the future.
