新生儿窒息是指婴儿出生后不能建立正常的自主呼吸而导致低氧血症、高碳酸血症、代谢性酸中毒及全身多脏器损伤,是引起新生儿死亡和儿童伤残的重要原因之一[1]。由于诊断标准未完全统一,国内文献报道的发病率差异很大[2-3]。1病因窒息的本质是缺氧,凡是影响胎儿、新生儿气体交换的因素均可引起窒息。可发生于妊娠期,但绝大多数发生于产程开始后。新生儿窒息多为胎儿窒息(宫内窘迫)的延续。1.1孕母因素(1)孕母有慢性或严重疾病,如心、肺 Neonatal asphyxia refers to the infants who can not establish normal spontaneous respiration after birth and lead to hypoxemia, hypercapnia, metabolic acidosis and systemic multiple organ injury, which is an important cause of neonatal death and child disability One 1]. As the diagnostic criteria are not completely uniformed, the incidence rates in the domestic literature vary greatly [2-3]. 1 cause of asphyxia is the essence of hypoxia, any impact on the fetus, neonatal gas exchange can cause suffocation factors. Can occur in pregnancy, but the vast majority occurred in the beginning of labor after. Neonatal asphyxia is mostly a continuation of fetal asphyxia (intrauterine distress). 1.1 pregnant mothers (1) pregnant mothers have chronic or serious diseases, such as heart and lungs
