Abstract：
Oral propranolol therapy is commonly used for the prevention of tachyarrhythmias in infancy and childhood. Propranolol is commercially produced in four concentrations allowing varying volumes to be administered. However, quite often an alternative strength of propranolol liquid is issued without clear change in instructions or warning. This may lead to parents inadvertently administering the wrong dose.
摘要：
口服普萘洛尔治疗通常用于预防婴儿期和儿童期的快速性心律失常。普萘洛尔在商业上以四种浓度生产,允许施用不同的体积。然而,普萘洛尔液体的替代强度通常是在没有明确的指示或警告变化的情况下发出的。这可能导致父母无意中施用错误的剂量。
