A four-year-old female patient presented to the emergency department with an epinephrine auto-injector that had unintentionally discharged into her mandible. There was difficulty removing the auto-injector at bedside. Images we acquired noted needle curvature not present in an off-the-shelf model. She was sedated, and the auto-injector was removed by retracing the angle of discharge, with care taken not to inject epinephrine into the patient.
Epinephrine auto-injector accidental discharges are an unusual injury pattern, but the incidence of such events is increasing in the United States. The emergency clinician should be cognizant of complicating factors with discharges, such as bent needles. Here we discuss a case of discharge into the maxillofacial region (lower jaw), with approaches to treatment.
一名4岁女性患者因肾上腺素自动注射器意外注入其下颌骨而被送往急诊科。在床边难以取出自动注射器。我们获取的图像显示针头弯曲，而现成的模型中不存在这种情况。她接受了镇静，通过沿注射角度回溯的方式取出了自动注射器，同时小心避免将肾上腺素注入患者体内。
肾上腺素自动注射器意外注射是一种不常见的损伤模式，但在美国此类事件的发生率正在上升。急诊医生应认识到注射时的复杂因素，如弯曲的针头。在此我们讨论一例注射到颌面区域（下颌）的病例及其治疗方法。
