Testing a glucose monitor in intensive care patients

This trial is testing the Dexcom G7, a wearable sensor that continuously monitors blood sugar levels, in patients who are critically ill in the intensive care unit. Researchers want to see how accurate and reliable this device is in patients undergoing major abdominal surgery or organ transplants who need close blood sugar monitoring. The study will compare how well the device works with and without extra calibrations to fine-tune its readings.

Patients in the intensive care unit often need insulin therapy to control their blood sugar during recovery from major surgery or transplants. Hospital staff currently rely on frequent blood tests to monitor glucose, which can be stressful and time-consuming. This trial aims to determine whether a continuous monitoring device could provide faster, more accurate readings to help doctors manage insulin therapy more safely.
