目的:评估纤支镜在小儿持续性喘息诊断中的有效性和安全性,为其临床应用提供研究依据。方法:因持续喘息6周以上,且支气管扩张及类固醇吸入治疗无效而采用纤支镜检查的患儿被纳入本回顾性研究。结果:自2002年至2009年共有113例持续性喘息患者被纳入研究。其中63%为男性。患儿平均年龄14个月(7~44个月),症状持续时间平均为5个月(2~14个月)。纤支镜在48%的患儿发现病理改变。38例患者为气管软化症,14例为异物吸入,2例为外部压迫气道造成。结论:纤维支气管镜检查可为持续性喘息的患儿提供一种快速、准确、安全的诊断。
Objective: To evaluate the effectiveness and safety of fiberoptic bronchoscopy in the diagnosis of persistent wheeze in infants and to provide the basis for its clinical application. METHODS: Children with bronchoscopy undergoing continuous wheeze over 6 weeks and having bronchodilator and steroid inhalation ineffective were included in this retrospective study. RESULTS: A total of 113 patients with persistent wheeze were included in the study from 2002 to 2009. 63% of them are men. Children with an average age of 14 months (7 to 44 months), the average duration of symptoms for 5 months (2 to 14 months). Bronchoscopy found pathological changes in 48% of children. Thirty-eight patients had tracheal irritation, 14 were aspirated and two were caused by external compression of the airway. Conclusion: Fiberoptic bronchoscopy can provide a rapid, accurate and safe diagnosis of persistent wheezing in children.
