摘要哮喘是儿童常见的呼吸道疾病，其治疗目标包括维持正常的活动水平，即运动能力，但在哮喘儿童运动过程中，可能会出现运动诱发的支气管痉挛(exercise-induced bronchoconstriction，EIB)。EIB需要紧急识别和处理，可通过运动激发试验来评估其严重程度。但运动激发试验所需设备价格高昂，实施难度较大，在临床上未能全面普及。因此，需要寻求更简便的方法在哮喘儿童中识别EIB，并应用于临床实践。该文通过介绍哮喘儿童EIB的定义和发病机制，总结EIB的诊断方法，并提供EIB的预防和治疗策略，从而帮助儿科医生更深入地了解EIB，能更好地指导哮喘儿童进行运动。

abstractsAsthma is one of the most common respiratory disease in children.Maintaining normal activity level(exercise ability) is the goal of treatment in children with asthma.However, when children with asthma do exercise, exercise-induced bronchoconstriction (EIB) may occur.EIB is a situation that needs urgent recognition and treatment, and its severity can be determined through exercise challenge testing.But exercise challenge testing needs the equipment that expensive and difficult to implement.And it has not been widely used in clinical practice.Therefore, we need to find a more convenient method to identify EIB in children with asthma and apply it to clinical practice.This article introduces the definition and pathogenesis of EIB in children with asthma, summarizes the diagnostic methods and the prevention and treatment of EIB, so as to help pediatricians understand EIB more deeply and instruct children with asthma to do exercise better.
