Summary

This observational study will check if diathermy, a tool used during surgery to stop bleeding, affects the accuracy of continuous glucose monitors in people with Type 1 Diabetes. About 126 adults and children will have their glucose readings compared before and after diathermy use. The goal is to see if the monitors stay reliable during surgery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If it works, this could help ensure glucose monitors remain accurate during surgery, improving safety for people with Type 1 Diabetes.
What could go wrong
This is an early observational study, not a treatment trial. It only looks at short-term effects during surgery, so results may not apply to other situations.

This is an AI summary of the original study and may miss details. Read our disclaimer.
