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60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42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治疗。支气管扩张剂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 causes of misdiagnosis of 60 children with CVA were analyzed. Application of aminophylline and glucocorticoid beclomethasone dipropionate (BK) inhalation therapy, observe its efficacy. Results 42 cases were 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. The diagnosis is through airway response measurement and experimental treatment. Bronchodilators β2 agonists and glucocorticoid inhalation treatment is better.
