Diphenhydramine (Benadryl) is a first-generation antihistamine that is used primarily to treat allergic reactions including anaphylaxis, urticaria, and allergic rhinitis. Despite its availability as an over-the-counter medication, toxicity may occur with its use especially when administered in large doses or via the intravenous route. We present a 3-month-old infant with Trisomy 21 who suffered a cardiac arrest immediately following administration of a single 1.25 mg/kg dose of intravenous diphenhydramine, prescribed for sedation in the Pediatric ICU setting. The potential cardiovascular and respiratory effects of diphenhydramine are presented, previous reports of life-threatening adverse effects reviewed, and options to limit these effects discussed.
苯海拉明(苯那君)是第一代抗组胺药,主要用于治疗过敏反应,包括过敏反应、荨麻疹和过敏性鼻炎。尽管它作为非处方药可以买到,但使用时可能会出现毒性,尤其是大剂量给药或静脉给药时。我们报告一例患有21三体综合征的3个月大婴儿,在儿科重症监护病房接受单次1.25mg/kg静脉注射苯海拉明用于镇静后立即发生心脏骤停。本文介绍了苯海拉明潜在的心血管和呼吸影响,回顾了既往关于危及生命不良反应的报道,并讨论了限制这些影响的方法。
