Continuous Glucose Monitoring in Cardiac Surgery
This study is testing how accurate the Dexcom G7 continuous glucose monitor (a device that tracks blood sugar levels) is for adult patients having heart surgery that involves a heart-lung machine (cardiopulmonary bypass). Researchers will compare the readings from the Dexcom G7 to standard blood sugar measurements taken during your surgery and recovery in the intensive care unit. They want to see how well the device works, especially when certain medications (vasopressors), low body temperature (hypothermia), or changes in blood chemistry (acidosis) are present. The goal is to improve how blood sugar is managed in these patients, which could lead to better health outcomes. You can join if you are 18 or older and having this type of heart surgery at Atrium Health Wake Forest Baptist Medical Center. The study is currently recruiting patients.
- Study design
- This interventional study plans to enroll 100 adult participants. It will compare the Dexcom G7 continuous glucose monitor readings to standard blood sugar measurements.
- What's involved
- You would have a Dexcom G7 continuous glucose monitor placed before your heart surgery. It would be worn continuously during your surgery, recovery, and while you are in the Cardiovascular Intensive Care Unit.
- Compensation
- Not stated in the trial record.
- Follow-up
- The accuracy of the continuous glucose monitor will be measured for up to 10 days, and specifically on day 1 for hypothermia.

What this trial measures
- Continuous Glucose Monitoring Accuracy Compared to Point-of-Care MeasurementsUp to Day 10
Glucose values (mg/dL) from the continuous glucose monitoring will be compared to glucose values obtained from point-of-care arterial blood gas and/or fingerstick capillary glucose measurements.
- Percentage of Continuous Glucose Monitoring Accuracy with Vasopressor UseUp to Day 10
Glucose values from the continuous glucose monitoring will be compared to glucose values obtained from point-of-care arterial blood gas measurements when vasopressors are utilized for hemodynamic optimization.
- Percentage of Continuous Glucose Monitoring Accuracy with HypothermiaDay 1
Glucose values from the continuous glucose monitoring will be compared to glucose values obtained from point-of-care arterial blood gas measurements during the hypothermic period intraoperatively.
- Percentage of Continuous Glucose Monitoring Accuracy with AcidosisUp to Day 10
Glucose values from the continuous glucose monitoring will be compared to glucose values obtained from point-of-care arterial blood gas measurements intraoperatively when the participant is acidotic.
