102例SARS患者胸片分析

Roentgenography in 102 Patients with severe acute respiratory syndrome (SARS)

目的 探讨严重急性呼吸综合征 (SARS)临床特点和转归。方法 回顾性分析北京某 SARS定点医院收治的 10 2例患者 ,对其病程中不同时期胸部 X线片进行分析。结果 3日内有 79.6 %、7日内有 97.4 %的患者出现胸片异常 ,10日内所有患者均出现胸片异常 ;首次异常胸片中 ,右侧肺炎占 4 3.1% ,以右下肺炎多见 ;双侧肺炎占 32 .4 % ,多叶肺炎占 4 0 .2 % ;19.6 %的患者在 <2周、32 .4 %的患者在 <3周、2 8.4 %的患者在 <4周肺炎吸收 ,仍有 8.8%的患者需要 >4周的时间吸收好转 ;<2周肺炎吸收好转的患者平均年龄较低 ;4例死亡患者 3例为双侧肺炎。结论 SARS可造成肺部多发炎症改变 ,大多 <4周吸收好转 ,有部分年龄较高者吸收延迟。

OBJECTIVE To study the characteristics of chest roentgenography in patients with severe acute respiratory syndrome (SARS). METHODS The chest roentgenography of 102 SARS patients from a specific SARS hospital was analyzed retrospectively. RESULTS The ratio of abnormal chest roentgenographic appearance within 3 days, 7 days and 10 days were 79.6%, 97.4% and 100%, respectively. First abnormal appearance showed right pneumonia accounted for 43.1% with right lower part pneumonia dominantly; bilateral pneumonia was 32.4% and multiple lobes pneumonia was 40.2%. Ratio of pneumonia absorption within 2 weeks, 3 weeks and 4 weeks were 19.6%, 32.4% and 28.4%, respectively. Still 8.8% patients needed more than 4 weeks to be improved. The average age of patients whose pneumonia absorbed within 2 weeks was younger. Three of those 4 died patients had bilateral pneumonia. CONCLUSIONS Multiple position pneumonia could be found in patients with SARS. Most of them improved within 4 weeks, the rest would delayed due to older age.
