喘憋性肺炎远期呼吸功能研究

A LONG-TERM STUDY ON THE RESPIRATORY FUNCTION AFTER ASTHMATIC SUFFOCATING PNEUMONIA

对50例喘憋性肺炎(喘肺)患几经8～14年的随访,结果显示:70％有喘息性支气管炎(喘支)病史,其中26％转变为支气管哮喘(哮喘),6％为不典型哮喘。喘支组的50％及25％的肺容量呼吸流速(V_(50)、V_(25))和最大呼气中段流速(MMEF)较对照组差异有显著意义,而哮喘组的呼气峰流速(PEFR)和用力呼气肺活量(FVC)、V_(50)、V_(25)、MMEF的差异均有显著性意义。运动试验显示病儿组44％具气道高反应性,与对照组相比有非常显著意义,喘支组与哮喘组间气道反应性呈交叉重叠现象,提示喘肺与哮喘之间存在密切关系。

50 children who suffered from asthmatic suffocating pneumonia have been followed-up for 8-14 years. 70% of cases had the history of episodes of wheezing bronchitis, 26% became bronchial asthma, 6% was atypical asthma. Compared with the control group there were significant differences in V50, V25 and MMEF between the wheezing bronchitis and the control group, and also in PEFR, FVC, V50, V25 and MMEF between the asthmatic and the control group. By exercising test it was noted that 44% of the diseased children had an airway hyperreactivity. Therefore, there were very significant differences compared with the control group. That the crossing overlapping phenomenon of the airway reactivity between the wheezing and the asthmatic group suggested that there was a correlation between the asthmatic suffocating pneumonia and asthma.
