Continuous Glucose Sensing at the Site of Subcutaneous Insulin Administration
Continuous Glucose Sensing at the Site of Subcutaneous Insulin Administration: Evaluation of a Novel Single-Port Treatment Approach in Type 1 Diabetic Patients During a 1-Day Stay in a Clinical Research Center and a 6-Day Period at Home
研究概览
详细说明
The treatment of type 1 diabetes usually comprises the measurement of glucose in blood obtained by finger pricking and the administration of insulin via subcutaneous bolus injection or continuous subcutaneous infusion.
This study seeks to test a new treatment approach where glucose sensing and insulin administration are combined and performed at a single subcutaneous tissue site (single-port treatment approach). A single-port device consisting of a continuous glucose sensor and an insulin infusion cannula is inserted into the subcutaneous tissue of 10 type-1 diabetes patients and used for insulin infusion and simultaneous glucose sensing over a 7-day period. The performance of the single-port device is assessed by comparing the obtained glucose readings with those of a blood glucose meter and an additionally worn control sensor.

实验性的：glucose sensing and insulin delivery
Subcutaneous insulin delivery with an insulin pump plus glucose sensing with a continuous glucose sensor placed at the site of subcutaneous insulin delivery. In parallel, capillary glucose determinations using a conventional glucose meter as well as glucose sensing in subcutaneous, insulin-unexposed tissue using a continuous glucose sensor. |
Subcutaneous insulin (100 U/ml, NovoRapid®; Novo Nordisk, Bagsvaerd, Denmark) delivery with an insulin pump (Vibe-TM; Animas Corp., West Chester, PA, USA) and an insulin infusion cannula (SOF-SET MICRO QR 6mm; Medtronic MiniMed, USA) placed at the same site as the continuous glucose sensor.
Glucose sensing with a continuous glucose sensor (Dexcom G4 Platinum Sensor; Dexcom Inc., San Diego, USA) placed at the site of subcutaneous insulin delivery.
