摘要

目的探讨支气管激发试验阳性率和FEF

75%

关系。方法将249例慢性咳嗽、胸闷、喘息患者并分为4组: FEF

75%

%Pred40%为A组，40%≤FEF

75%

%Pred60%为B组，60%≤FEF

75%

%Pred80%为C组，FEF

75%

%Pred≥80%为D组，进行支气管激发试验，并分析支气管激发试验结果的阳性率与患者基础FEF

75%

值之间关系。结果 A组和B组间的支气管激发试验阳性率相差不显著（P0.05），A、B组与C组、D组间支气管激发试验阳性率相差非常显著（P0.01），C组与D组间支气管激发试验阳性率相差显著（P0.05）。且A组与其他各组支气管激发试验阳性患者的激发阳性剂量相差显著（P0.05）。结论支气管激发试验阳性率与FEF

75%

减低有关。

Abstract

Objective To study the relationship between FEF

75%

and positive rate of bronchial provocation tests. Methods A total of 249 patients with chronic cough

choking sensation in chest

and gasp underwent bronchial provocation tests and were divided into four groups: Group A (FEF

75%

%Pred40%)

Group B(40%≤FEF

75%

%Pred60%)

Group C(60%≤FEF

75%

%Pred80%)

and Group D(FEF

75%

%Pred≥80%). The relationship between FEF

75%

and positive rate of bronchial provocation tests was analyzed. Results There was no significant difference in bronchial provocation tests between Group A and

Group B (P0.05) but significant difference between Groups A

B and Groups C

D. The difference between Group C and Group D was also significant (P0.05). The positive doses in Group A were significantly different from those in other groups. Conclusion The positive rate of bronchial provocation tests may be related with the reduced FEF

75%
