【摘要】：回顾性分析1例用力呼气激发阳性哮喘患者8年肺功能变化情况。患者男,39岁,2014年3月因咳嗽,喘息8年加重2月就诊,查肺通气功能FEV1=2.51L,FEV1%64%.FEV1/FVC=0.44,30s后行肺通气检查时FEV1降至2.18L,1分钟后第三次行肺通气功能检查时FEV1下降至2.01L,1分钟后第四次行肺通气检查时FEV1降至1.73L,四次用力呼气后,FEV1下降31%,用力呼气激发阳性,提示存在极高气道反应性。追踪病史及肺功能回顾:患者2006年9月我院确诊哮喘,肺功能FEV1=3.00L,FEV1%68.9%治疗3月后肺通气功能接近正常。2009年10月复查示重度阻塞,治疗半年后肺功能恢复基本正常。2014年2月烟花味刺激后出现重度哮喘发作;2014年3月复查示用力呼气激发阳性。提示,长期未控制哮喘可出现用力呼气激发阳性,高度气道反应哮喘患者需更长时间规范治疗。
[Abstract]:The changes of pulmonary function in a patient with forced expiratory provocation positive asthma were analyzed retrospectively. The patient male, 39 years old, went to hospital for 2 months due to cough and wheezing for 8 years in March 2014, and the FEV1 was decreased to 2.18 L during the pulmonary ventilation examination after checking the pulmonary ventilation function (FEV1=2.51L,FEV1d%.FEV1/FVC=0.44,30s). One minute later, FEV1 decreased to 2.01 L at the third pulmonary ventilation test, and 1.73 L at the fourth pulmonary ventilation test 1 minute later. After four forced exhalations, FEV1 decreased by 31%, and forced expiratory stimulation was positive. It is suggested that there is a very high airway reactivity. Follow-up history and pulmonary function review: patients with asthma confirmed in our hospital in September 2006, pulmonary function FEV1=3.00L,FEV1h.9% treatment 3 months after the pulmonary ventilation function close to normal. October 2009 re-examination showed severe obstruction, After half a year of treatment, pulmonary function returned to normal, and severe asthma occurred after firework-smelling stimulation in February 2014. Reexamination in March 2014 showed positive for forced expiratory excitation. It is suggested that long-term uncontrolled asthma may be positive for forced expiratory excitation, and patients with high airway reaction may need longer and more standardized treatment.
