Smart monitor alerts could keep surgical diabetes patients safer
NCT ID NCT06314061
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a continuous glucose monitor (CGM) that alerts nurses to high or low blood sugar can help surgical patients with diabetes keep their glucose levels in a safe range. About 200 adults with diabetes who had surgery wore the Dexcom G7 device for up to 10 days. The goal was to see if real-time alerts lead to better blood sugar control compared to standard finger-stick checks.
