DETERMINATION OF NEEDLE LENGTH FOR INTRAMUSCULAR INJECTION OF EARLY ADOLESCENTS

这个子项目是许多研究子项目中利用 资源由NIH/NCRR资助的中心拨款提供。子项目和 调查员(PI)可能从NIH的另一个来源获得了主要资金， 并因此可以在其他清晰的条目中表示。列出的机构是 该中心不一定是调查人员的机构。 有必要为接受肌肉免疫的青少年确定适当的针头长度，并确定它是否受患者年龄、性别、体重和/或给药技术的影响。这可以利用超声技术来获得三角肌注射部位肌肉深度和距离的客观测量。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. There is a need to determine the appropriate needle length for adolescents receiving intramuscular immunization and determine if it is influenced by patient age, gender, body weight, and/or administration technique. This can be accomplished utilizing ultrasound technique to obtain objective measurements of muscle depth and distance to bone at the deltoid injection site.
