Aims: To define the normal ranges of the thicknesses of the skin and subcutaneous tissues via ultrasonography, and to determine whether the current syringe needle-lengths used for the subcutaneous injections were appropriate.
Methods: The thicknesses of the skin and subcutaneous tissues of 2 244 students were measured at the left arm using ultrasonography. Patients were divided into three groups based on age: 68, 912 and 1317 year.
Results: The thicknesses of the skin, subcutaneous tissue and skin-subcutaneous tissue were found to be positively correlated with age, BMI and body surface area. All these were observed to be gender related. There is a possibility to make intramuscular injections for the 50, 25 and 25% of boys with age groups of 68, 912 and 1317 year respectively. For the girls, the risk of intramuscular injection is 25% for all age groups.
Conclusions: Our study has shown that the skin and skin-subcutaneous tissue thicknesses varies as a function of age, gender, BMI and body surface area.
