The project will begin with a feasibility study to pilot the study set up and to address the specific needs of the studies population by comparing closed loop insulin delivery using standard strength insulin and diluted insulin. The results will feed into the design of the main study.
We hypothesise that diluted insulin will lead to more stable glucose levels by reducing inaccuracies accentuated by delivery of minute amounts of insulin (frequently less that 0.1U/h [1μl/h with standard strength insulin] in small children compared to 1U/h in adults). These inaccuracies may result from pump plunger micro-jumps, tissue pressure build-up, and infusion set kinking.
