目的　探讨儿童咳嗽变异性哮喘 (CVA)的临床特点及诊疗要点。方法　分析 6 0例儿童CVA的临床表现和误诊原因。应用氨茶碱及糖皮质激素丙酸倍氯米松 (必可酮 )雾化吸入进行治疗 ,观察其疗效。结果　 4 2例曾被误诊为支气管炎。临床上治疗用氨茶碱、糖皮质激素吸入有明显效果。结论　提高对CVA的认识及仔细询问病史是防止漏诊、误诊的关键 ,必要时可做肺功能检查 ,确诊是通过气道反应测定及进行试验性治疗。气管扩张剂 β2 受体激动剂及糖皮质激素吸入治疗效果较好。 Objective To investigate the clinical features and diagnosis and treatment of children with cough variant asthma (CVA). Methods The clinical manifestations and misdiagnosis of 60 children with CVA were analyzed. Application of aminophylline and glucocorticoid beclomethasone dipropionate (BK) inhalation therapy, observe its efficacy. Results 42 cases had been misdiagnosed as bronchitis. Clinical treatment with aminophylline, glucocorticoid inhalation have a significant effect. Conclusion To improve the understanding of CVA and carefully ask medical history is the key to prevent misdiagnosis and misdiagnosis. If necessary, pulmonary function tests can be performed. Diagnosis is confirmed by airway reaction and experimental treatment. Tracheostomy β2 receptor agonists and glucocorticoid inhalation treatment is better.
