Evaluating continuous glucose monitors during surgery in youth with type 1 diabetes

Official title: Accuracy of Continuous Glucose Monitors During the Perioperative Period in Youth With Type 1 Diabetes

Run by University of Colorado, Denver · NCT06575842 · Data updated 2026-11-12

This study is testing how well continuous glucose monitors work for young people with type 1 diabetes during surgery to see if they can safely replace traditional blood tests while under anesthesia.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are youth aged 2 to 26 with type 1 diabetes who are on insulin therapy and currently using a continuous glucose monitor.

Probably not a fit

Patients who are pregnant, using hydroxyurea, or have conditions preventing participation will not benefit from this study.

What this trial studies

This observational study assesses the accuracy of continuous glucose monitors (CGMs) in youth with type 1 diabetes during surgical procedures that require anesthesia. Participants aged 2 to 26 will have their CGM data compared to venous blood glucose measurements to determine the reliability of CGMs in this critical setting. The study aims to fill the knowledge gap regarding the effectiveness of CGMs as a sole glucose monitoring source during anesthesia. By collecting data from participants undergoing surgery, the study seeks to provide insights into the safety and accuracy of CGMs in perioperative care.

Why it matters

Potential benefit: If successful, this study could enhance the safety and management of glucose levels in youth with type 1 diabetes during surgical procedures.

How similar studies have gone: There is limited data on the accuracy of continuous glucose monitors during anesthesia, making this study a novel approach.
