Test with Dexcom G7 glucose monitor during heart surgery
Official title: Continuous Glucose Monitoring in Patients Undergoing Cardiopulmonary Bypass
Run by Wake Forest University Health Sciences · NCT06861881 · Data updated 2026-11-12
Researchers will see if the Dexcom G7 continuous glucose monitor accurately reflects blood sugar during cardiopulmonary bypass and in the ICU after heart surgery in adults.

Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older undergoing cardiac surgery with cardiopulmonary bypass at Wake Forest Baptist Medical Center.
✕Probably not a fit
Patients with contraindications to sensor placement on the posterior arm, or those not using Dexcom monitoring, may not receive benefit.

What this trial studies
This trial compares Dexcom G7 glucose readings to standard blood glucose tests in adults undergoing cardiac surgery with cardiopulmonary bypass. It aims to assess accuracy during physiologic changes such as vasopressor use, acidosis, and hypothermia, across a sizable, well-defined patient group. Data will come from intraoperative and postoperative periods in the cardiac ICU, with the goal of informing future use of continuous glucose monitoring in this setting. The study could support earlier detection of out‑of‑range glucose values and potentially improve insulin management and glucose control for better outcomes. If successful, this would be among the first reports detailing intraoperative use of the Dexcom G7 in cardiac surgery.
Why it matters
Potential benefit: If successful, patients could benefit from more accurate and timely glucose monitoring during and after surgery, which may improve glucose control and outcomes.
How similar studies have gone: Earlier studies with continuous glucose monitoring in perioperative settings have shown promise, but this would be among the first to assess the Dexcom G7 in intraoperative cardiac procedures.
