婴幼儿急性下呼吸道感染后6～7年临床随访及肺功能变化

Clinical Outcome and Pulmonary Function Changes 6～7 Years after Acute Lower Respiratory Tract Infection in Infancy

对３９例２岁以内急性下呼吸道感染患儿于６～７年后随访，结果３岁以前反复下呼吸道感染（反复下感）１９例（４８．７％），随访时仍反复下感４例（１０．３％）。入院时患毛细支气管炎的比患肺炎易反复罹患下呼吸道感染（Ｐ＜０．０１）。反复下感组的肺功能检查显示ＰＥＦＲ、Ｖ５０及Ｖ２５明显降低，与健康对照组比较有显著差异。

The clinical outcome and pulmonary function changes of 39 children 6～7 years after acute lower respiratory tract infection were reported in this paper. The data of clinical follow-up showed that 19 children(48.7%)had many episodes of recurrent lower respiratory tract infection(RLRTI)before 3 years of age. Among them 4 children still suffered frome RLRTI in follow-up.Pulmonary function tests showed that PEFR,V50 and V25 in children with RLRTI were markedly decreased in comparison with healthy control group.These results suggest that infants with acute lower respiratory tract infection tend to have the RLRTI and the pulmornary function were also damaged 6～7years later after the first episode.
