Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Summary

This study tested how well the Dexcom G6 continuous glucose monitor matches standard blood glucose checks in 40 adults after heart surgery. Participants wore the sensor on their arm for up to 10 days while in the ICU and regular hospital floors. The goal was to see if the device could reliably track glucose levels without frequent fingerstick tests.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Dexcom G6 continuous glucose monitor (device)
What this could lead to
If successful, this could show that continuous glucose monitors are accurate enough to replace frequent fingerstick checks after heart surgery, making monitoring easier for patients.
What could go wrong
This is a small, early-stage study with only 40 participants, so results may not apply to all patients. The device might be less accurate in critically ill patients after surgery.
