Can a Stick-On sensor replace finger pricks before surgery?
NCT ID NCT05937373
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tested whether continuous glucose monitors (CGMs) could be used in the days before and after surgery to track blood sugar in people with diabetes. Researchers placed a CGM sensor on 22 patients during a preoperative visit and compared its readings to standard finger-stick tests and lab results. The goal was to see if the CGM was accurate and practical for managing glucose around the time of surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Continuous glucose monitor (CGM) device
- What this could lead to
- If successful, this could show that CGM devices work well enough to manage blood sugar before, during, and after surgery, possibly improving care.
- What could go wrong
- This was a very small pilot study (22 people) that was terminated early, so results are limited and may not apply broadly. Accuracy issues or device failures could occur.
