ClinConnect Summary

This clinical trial is looking at how well the Dexcom G7 Continuous Glucose Monitoring System works compared to traditional methods of checking blood sugar levels in patients who have just had heart surgery. During the study, participants will have their blood sugar measured every 1-3 hours using both the continuous glucose monitor and a fingerstick test, which is a common method where a small drop of blood is taken from a fingertip. The goal is to see how closely the two methods agree with each other and to identify any errors in the readings.

To be eligible for this trial, participants must be 18 years or older and have planned heart surgery. They can have diabetes or not, but most patients in the intensive care unit will need extra insulin due to high blood sugar levels. Important factors that would exclude someone from participating include allergies to the continuous glucose monitor materials, certain skin conditions, pregnancy, or if they are using special heart devices. Participants can expect to have their blood sugar monitored closely during their hospital stay, helping researchers gather valuable information about glucose monitoring after surgery.
