一项老年患者（年龄：65岁）的超声研究显示，男性（优势臂r = 0.69，非优势臂r = 0.71）和女性（双臂r = 0.79）的体重指数（BMI）与三角肌皮下层厚度密切相关。BMI与男性相同的女性，皮下层明显较厚（p = 0.0001），肌肉层较薄（p = 0.0003），三角肌肌内注射所需的最小针头长度由BMI组定义，其中针头与肱骨长轴成90度进入。在所有BMI男性和女性中，BMI < 35，肌肉注射可以用25 mm长的针头实现，而在BMI > 35的女性中，需要32 mm长的针头。这些数据将用于研究，以解决关于最佳给药途径的临床平衡（肌肉注射与皮下注射）疫苗（如流感疫苗和肺炎球菌疫苗），这些疫苗是通过公共卫生计划为老年人提供的。(c)2005爱思唯尔有限公司保留所有权利。
An ultrasound study in elderly patients ( :65 years) showed that body mass index (BMI) was strongly correlated with deltoid subcutaneous layer thickness in males (r = 0.69 dominant arm, 0.71 non-dominant arm) and females (r = 0.79 both arms). Females with the same BMI as males had significantly thicker subcutaneous layers (p = 0.0001) and thinner muscle layers (p = 0.0003).Minimal needle length required for deltoid intramuscular injection where the needle was entered at 90 degrees to the long axis of the humerus was defined by BMI group. In all BMI males and females, BMI < 35, intramuscular injection could be achieved with a 25 mm long needle, whilst in females BMI > 35, a 32 mm long needle is required.These data will be used in studies to resolve the clinical equipoise regarding the optimal route of administration (intramuscular versus subcutaneous) of vaccines (e.g. influenza and pneumococcal vaccines), which are provided through public health programs for the elderly.
