RESUMO
The hyaline membrane disease is not a common disease in Korea. Only a few reports of small scale are avaiable in the literature. We have experienced 5 cases of HMD during approximately 1 year period. The diagnosis was made either on characteristic clinical and roentgenological features or postmortem examination. The birth weights of these cases were in the range of 1,000-1,500gm in 2 cases and 2,000-2,500gm in 3 cases. And their gestational age was 28-34 weeks in most of the cases. Three cases were delivered by C-section. There was 1 case of placenta previa. Four of these 5 cases died after average 18 hours postnatum. Postmortem findings in two cases were characterized by typical hyaline membrane lining th respiratory bronchioles and alveolar ducts. Other prominent findings were atelectasis, interstitial edema and congestion and lymphatic dilatation. One case complicated with multifocal bronchopneumonia and perinatal telencephalic leukoencephalopathy. The other case showed acute subarachnoid hemorrhage probably from germinal matrix hemorrhage.
