Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
Children and adolescents with type 1 diabetes mellitus are required to inject insulin daily. The injection technique should reliably deposit insulin into subcutaneous fat while minimizing inadvertent delivery into either the skin or the underlying muscle, both of which are associated with suboptimal outcomes. The use of shorter, thinner needles reduces the incidence of intramuscular delivery and is associated with reduced discomfort, but increases the risks of both shallow (intradermal) delivery and of loss of insulin through backflow to the skin surface.

In the current study, 240 subjects (children and adults) will receive multiple injections of small volumes of sterile air in the thigh and abdomen using 5 mm Novofine® needles, to simulate insulin injections performed at the two sites using various injection techniques (perpendicular or angled needle, with or without skin fold). Ultrasound visualisation of the injected air will allow determination of the incidence of intradermal or intramuscular delivery using the various delivery methods in the trial. In addition, adult subjects will receive injections of a liquid test medium in order to determine the incidence and extent of backflow. Qualitative data on perceived discomfort and information on body composition will also be collected. This investigation will form the basis for recommendations regarding preferred injection technique where 5 mm needles are used.
