儿童慢性咳嗽:基于干性与湿性分类的诊疗策略OA

Chronic cough in children(lasting＞4 weeks with no significant abnormalities on chest X-ray)is a common yet challenging management issue in pediatric outpatient practice.This article focuses on this condition and proposes a clinical diagnostic and therapeutic framework based on initial classification of dry and productive cough.This framework helps clinicians quickly narrow down the focus to the most common etiologies,such as cough variant asthma,upper airway cough syndrome,and protracted bacterial bronchitis.It guides targeted evaluation and treatment,emphasizes time-limited diagnostic treatment trials in special outpatient settings,and standardizes the referral pathway.The goal is to reduce the misuse of antibiotics and antitussives,achieve precise management,and improve patient outcomes.
