目的总结鼻后滴漏综合征(postnasal drip syndrome,PNDS)引起儿童慢性咳嗽的临床特点,提高对PNDS引起儿童慢性咳嗽的认识。方法回顾性分析2005年10月至2006年11月,在深圳市妇幼保健院儿科门诊就诊的PNDS引起慢性咳嗽的55例患儿的诊治过程及转归情况,总结诊治经验。结果55例患儿均以慢性咳嗽为主诉,病程超过4周,X线胸片检查无异常。确诊PNDS后,经相关治疗,症状明显消失或减轻。结论PNDS是引起儿童慢性咳嗽的主要原因之一,因病因多且与临床症状的关系复杂而易被误诊、漏诊并导致误治。当慢性咳嗽久治不愈且易反复时,应考虑此病的可能性,并给予针对性治疗。
Objective To summarize the clinical features of chronic cough caused by postnasal drip syndrome (PNDS) in children and to improve their understanding of PNDS-induced chronic cough in children. Methods A retrospective analysis was made on the diagnosis and treatment of 55 children with chronic cough caused by PNDS during their pediatric outpatient visits from October 2005 to November 2006 in Shenzhen MCH. The experience of diagnosis and treatment was summarized. Results 55 cases of children were mainly chronic cough, duration of more than 4 weeks, X-ray examination was normal. After the diagnosis of PNDS, the relevant treatment, the symptoms disappeared or reduced significantly. Conclusions PNDS is one of the main causes of chronic cough in children. Due to the complex etiology and complicated relationship with clinical symptoms, PNDS is easily misdiagnosed, misdiagnosed and misdiagnosed. When chronic cough persists and easy to repeat, should consider the possibility of this disease, and give targeted treatment.
