一、患婴为足月自然娩出婴,出生时按Apgar氏法评为10分;生后24小时已严重发绀、呼吸衰竭及全身衰竭,处于垂危状态。故首先应考虑呼吸系统疾病,如吸入性肺炎、肺不张、湿肺、肺透明膜病(新生儿呼吸窘迫综合征)等。但仍须注意排除产伤所致的颅内出血、气胸以及先天性畸形,如先天性心脏病、膈疝等的可能。 First, the baby is full-term natural delivery of infants, according to Apgar’s law at birth was rated 10 points; 24 hours after birth has been severely cyanotic, respiratory failure and systemic failure, in a dying condition. Therefore, we should first consider respiratory diseases, such as aspiration pneumonia, atelectasis, wet lung, hyaline membrane disease (neonatal respiratory distress syndrome) and so on. However, care should be taken to exclude intracranial hemorrhage due to trauma, pneumothorax and congenital malformations, such as congenital heart disease, diaphragmatic hernia and so on.
