Skin and subcutaneous thickness at injecting sites in children with diabetes: ultrasound findings and recommendations for giving injection
Pediatric Diabetes, 05/17/2012
Presti DL et al. – It seems medically appropriate for all children to use short needles where possible to minimize inadvertent IM injections which may increase glycemic variability. Methods One hundred one children with type 1 diabetes were divided into three groups according to age: 2–6, 7–13, and 14–17 yr. The thickness of skin and subcutaneous (SC) tissue was measured by ultrasound in all injection sites. Results
Skin thickness varied from 1.58mm in the arm of the youngest children to 2.29mm in the buttocks of the adolescents. Values decreased progressively based on age (2–6 < 7–13 < 14–17) and on body site (arm < thigh < abdomen < buttocks). Skin + SC thickness varied in a similar fashion. The skin surface to muscle distances were <4mm in nearly 10% of children, especially in the 2–6 yr group. This rate of IM injections doubles when using the 5–mm needle, and when injections are given under similar conditions it triples using the 6–mm needle.
