新生儿窒息是出生时以呼吸障碍为主的症候群。凡能降低血氧的任何因素,均可引起胎儿或新生儿窒息。约5%的胎儿可因胎盘、脐带或产科因素引起分娩时不同程度的窒息,引起胎儿死亡或娩出后因严重脑损害而死亡。虽有少数出生时情况尚好,但不能自动呼吸,多是由于母亲用麻醉剂的影响或呼吸道梗阻所致,因而在娩出后发生窒息。一 Neonatal asphyxia is a respiratory syndrome-predominant syndrome at birth. Any factor that reduces blood oxygen can cause asphyxiation in the fetus or newborn. About 5% of fetuses may cause different degrees of suffocation during childbirth due to placenta, umbilical cord or obstetric factors, causing fetal death or serious brain damage after delivery. Although a few are still in good condition at birth, they can not breathe spontaneously. Mostly due to the effects of anesthesia or respiratory obstruction, the mother suffers asphyxiation after delivery. one
