Can a wearable glucose sensor survive the operating room?

This pilot study tests whether the Dexcom G7 continuous glucose monitor, a wearable sensor that tracks blood sugar, can maintain a reliable connection during surgery. The device is placed on either the upper arm or the lateral thigh in adults undergoing operations lasting at least three hours. Researchers will measure how often the sensor stays connected, especially during the use of electrocautery, which may interfere with the signal. The goal is to see if this technology can be used effectively in the operating room.
