Accuracy of Continuous Glucose Monitors in Youth with Type 1 Diabetes During Surgery

This study is looking at how accurate continuous glucose monitors (CGMs) like Dexcom G6, G7, Freestyle Libre 2, 2 Plus, or 3 are for young people with Type 1 Diabetes during surgery. Researchers will compare CGM readings to standard blood glucose measurements taken from an IV or fingerstick. The goal is to see if CGMs can reliably track blood sugar levels during these procedures, as there isn't much information about this yet. You may be able to join if you are 2 to 26 years old, have Type 1 Diabetes, are on insulin, and already use a CGM, and will be having surgery that requires anesthesia. The study aims to determine the accuracy of CGM readings compared to traditional blood glucose tests.

Study design
This is an observational study involving about 120 participants. It means researchers will collect information without giving any specific treatments.
What's involved
You would have your continuous glucose data and blood glucose data collected during your surgical procedure. The length of time will vary based on your specific surgery.
Compensation
Not stated in the trial record.
Follow-up
The primary outcome is measured perioperatively (around the time of surgery), but a specific follow-up duration is not mentioned.
