支气管舒张试验的两种选择标准及阳性率结果的比较研究

Comparative study of two kinds of bronchial dilation test standard

目的比较支气管舒张试验的两种选择标准及阳性率结果,对支气管哮喘诊治的意义。方法以FEV1<70%预计值为标准选择行支气管舒张试验的患者62例,作为对照组;以FEV1%(一秒率)<75%为标准选择行支气管舒张试验的病人有88例,作为实验组,所有入选患者行支气管舒张试验,分别统计入选率及阳性率。结果对照组入选率为31.0%,阳性率为15.0%;实验组入选率为44.0%,阳性率为23.5%,两组入选率及阳性率比较有显著差异(P>0.05)。结论以FEV1%<75%为选择支气管舒张试验的标准,可以更多的发现阳性患者,更及时的确诊,同时也为哮喘的临床诊断和研究带来积极意义。

Objective To compare two selection standards and positive results of bronchial dilation test.Methods 62 patients with FEV1 70% of expected value in bronchial dilation test were selected as the control group,and 88 patients with FEV1%（ forced expiratory flow in one second）〈 75% in bronchial dilation test were selected as the experimental group. Bronchial dilation tests were carried out in all selected patients in order to count the selected rate and positive rate,respectively. Results The selected rate of the control group was 31. 0% and the positive rate was 15. 0%. The selected rate of the experimental group was 44. 0%,and the positive rate was 23. 5%.Conclusion If FEV1 〈75% is set as the selection standard,more positive patients can be selected and timely diagnosis,which is positive for the clinical diagnosis and research of asthma.
