Kurzbeschreibung
This is an exploratory prospective study primary aiming to evaluate differences between Point-of-care (POC) testing (standard of care) and Dexcom G6 CGM (Continues Glucose Monitoring sensor system) in 1) glycemic control measured by mean daily blood glucose and 2) identifying hypoglycemic and hyperglycemic events - in patients with type 1 and type 2 diabetes treated with basal bolus insulin regimen.
Ausführliche Beschreibung
Several studies have shown that the use of a device that can measure blood glucose levels every 5 minutes is more effective in identifying low blood glucose (hypoglycemia) and high blood glucose (hyperglycemia) when compared to regular measurements with fingersticks \[point of care (POC)\].
This is an exploratory prospective study primary aiming to evaluate differences between Point-of-care (POC) testing (standard o...

ExperimentellDexcom G6 CGM - Continues Glucose Monitoring sensor system The Dexcom G6 CGM is a commercially available factory-calibrated sensor system. The system measures interstitial glucose every 5-15 minutes, providing real-time and more complete glycemic profile during 24-hours compared to standard POC glucose testing, and replaces the need for finger sticking. Potential limitations include the need for removing the sensor before MRI or diathermy treatment, and the potential interfe...Mehr anzeigen | Dexcom G6 CGM - Continues Glucose Monitoring sensor system A blinded factory-calibrated continues glucose monitoring sensor system Dexcom G6 will be placed shortly after admission. Two CGM devices will be inserted in all patients - one in the abdomen and one in the arm to also assess differences in blood glucose readings between upper extremity and abdominal insertion sites. Information on CGM readings will be collected daily during the hospital stay and after hospital disch...Mehr anzeigen POC BG - Point-of-Care Blood Glucose monitoring Standard of care - bedside point-of-care (POC) capillary blood glucose (BG) monitoring will be done before meals and bedtime daily during the hospital stay and after hospital discharge for 10 days. |
