NCT03935919

Brief Summary

The purpose of this study it to assess whether the continuous glucose monitor system Dexcom G6® can be reliably used for perioperative glucose monitoring in 20 prediabetic or diabetic patients undergoing abdominal surgery in terms of data continuity, accuracy and patient tolerability.

  • Aged ≥18 years
  • Pre-diabetic (HbA1c 5.7-6.5%) or diabetic (regardless of aetiology)
  • Scheduled to have elective abdominal surgery at the University Hospital Bern
  • Surgery duration \>2 hours

You may not qualify if:

  • Planned MRI procedure during hospitalization
  • Inability to follow procedures
  • Incapacity to give informed consent
  • Presence of extensive skin abnormalities at the sensor insertion site (upper arm)
  • Known allergic/irritative skin reactions to dressings/adhesives
  • Haematocrit values outside the normal range
