摘要 目的:观察和评价运动诱发试验在哮喘儿童中的实施以及对运动诱发性哮喘诊断筛查的临床意义。方法:实施运动诱发试验,对象为92例7~15岁儿童哮喘,呼气峰流速测定,资料处理采用 SPLM3.0医用统计软件。结果:92例中试验阳性40例,总阳性率为43.48%,其中男性27例,阳性率52.94%,女性13例,阳性率31.71%,P<0.05。各观察指标的平均值在阳性与阴性组的差异在于:病程:3.04±2.81/1.56±0.84年,P=0.03。血嗜酸细胞(%):5.42±1.71%/3.56±1.39%,P<0.001。。总 IgE 浓度:421.90±123.28/258.33±91.76(IU/ml),P<0.001。ECP:5.14±2.03,3.04±0.89(ug/L),P<0.001 PEF 测定结果统计见表1。结论:运动激发试验可作为筛查运动诱发性哮喘的简单方法,试验的阳性与患者的性别,病程,血嗜酸细胞,总 IgE 浓度,ECP 值的不同而有差异。测定 PEF 值的变化可作为诊断的指标。
