Yenidoğan Aşılamasında Yüzeyel Doku Ultrasonografisinin Kasiçi Enjeksiyon Tekniği Ve iğne Uzunluğu Seçimine Katkısı

Introduction: The thickness of subcutaneous tissue and muscle layer is the most important parameter in vaccine injection. The tissue thickness determines the appropriate injection technique and needle size. Material and Method: We measured subcutaneous tissue and muscle layer thickness in deltoid and thigh region in 38 healthy (1-8 days) infants with ultrasonography and intended to determine the injection technique and needle length via these ultrasonographic measurements. Discussion: Significant relationship between the body weight and subcutaneous layer thickness in deltoid region was found (r: 0.48, p: 0.004). We concluded that the use of the stretching technique (minimizing the subcutaneous tissue) in combination with 8-10 mm needles is optimal for intramuscular injection in deltoid and thigh regions in infants.
