Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
For the study, subjects will be provided with an investigational Medtronic Real-Time Continuous Glucose Monitor (CGM) Enlite Sensor/Serter to help identify, serious hyperglycemia or hypoglycemia during the study. This sensor is not yet FDA approved, but is similar to commercially available sensors. If the sensor detects a high or low glucose, subject must obtain a fingerstick glucose to confirm the result. In the study, all insulin dose and other treatment decisions will be made using glucose meter results, and will not be based on sensor results. Subjects will be instructed on how to identify infusion set failures.
Infusion set failure are defined as: 1) Blood ketones greater than 0.6 mmol/L, 2) Evidence of infection at the infusion site (such as redness of more than 4 mm), or 3) Blood glucose that does not decrease by at least 50 mg/dL within 1 hour of a correction bolus to treat a blood glucose greater than 300 mg/dL.
Subjects will follow-up weekly in one of our test centers for a total of five visits.
At home subjects will be asked to keep a log recording measurements of redness and induration at the infusion site when it is changed prior to the study visit.
