以死胎,死产及非肺炎早期新生儿尸检51例对照,观察159例早期新生儿肺炎尸检资料。根据肺部病变将新生儿肺炎分为急性弥漫型,急性小灶型,支气管、支气管周围型,间质型及肺炎合并透明膜型5类,其中以急性弥漫型最常见。同时认为肺内有羊水吸入并不一定是吸入性肺炎及时对早期新生儿肺炎应予重视. Fifty-one neonates with stillbirth, stillbirth and early neonatal non-pneumonia were examined by autopsy for 159 cases of early neonatal pneumonia. Neonatal pneumonia is divided into 5 categories: acute diffuse type, acute small type, bronchial type, peripheral bronchial type, interstitial type and pneumonia with transparent membranous type according to pulmonary lesion, of which acute diffuse type is most common. At the same time that there is not necessarily inhaled amniotic fluid in the lung aspiration pneumonia in early neonatal pneumonia should pay attention.
