新生儿窒息系指胎儿娩出后仅有心跳而无呼吸的一系列呼吸衰竭的临床表现。它是胎儿宫内窘迫的继续,是新生儿的常见病理状态,需要紧急抢救和正确处理。病因新生儿窒息往往是因胎儿宫内窘迫,缺氧造成呼吸中枢抑制引起的。凡是足以造成母体和胎儿间血液循环和气体交换障碍,使血氧浓度降低的任何因素,皆可造成胎儿宫内窘迫,进而导致新生儿窒息。其原因可分以下三个方面:一、胎内因素:1.母体疾病:心血管病、低血压、严重贫血、妊娠毒血症、急慢性传染病等,使胎盘血液灌注减少,引起胎儿缺氧。2.子宫因素:多胎及羊水过多,使子
Neonatal asphyxia refers to the clinical manifestations of a series of respiratory failure with only a heartbeat and no breathing after the baby is delivered. It is the continuation of fetal distress, is a common neonatal pathological state, the need for emergency rescue and proper treatment. Cause of neonatal asphyxia is often due to fetal distress, hypoxia caused by inhibition of the respiratory center. Any factor sufficient to cause blood circulation and gas exchange between the mother and the fetus to reduce the concentration of oxygen can cause fetal distress and subsequent asphyxiation in the newborn. The reasons can be divided into the following three aspects: First, fetal factors: 1. Maternal diseases: cardiovascular disease, hypotension, severe anemia, gestational blood poisoning, acute and chronic infectious diseases, so that reduced placental blood perfusion, causing fetal hypoxia . 2. Uterine factors: polyhydramnios and polyhydramnios, so sub
