新生儿窒息是新生儿死亡的主要原因之一,在体重大于500g的31105个活产婴儿中,窒息的发生率为1.16％。窒息婴儿的死亡率为非窒息婴儿的88倍。窒息的不良影响可累及各系统如神经、呼吸、心血管、胃肠道和肾脏等。近年来,窒息对心血管系统的影响越来越引起人们的注意。现将窒息对新生儿心血管系统影响的有关向题综述如下。室息后新生儿心血管系统的病理改变 60年代人们就对窒息患儿心脏的病理变化进行研究。Burnard等检查因窒息死亡的新生儿心脏,发现其重量大于相应体重的对照组,并多数有心室
Neonatal asphyxia is one of the major causes of neonatal death, with an incidence of asphyxia of 1.16% in 31,105 live births weighing more than 500g. Asphyxial infants 88 times more likely to be non-asphyxiated infants. Adverse effects of asphyxia can affect various systems such as nerves, respiration, cardiovascular, gastrointestinal tract and kidneys. In recent years, the impact of asphyxiation on the cardiovascular system has drawn increasing attention. The relevant questions about the impact of asphyxia on neonatal cardiovascular system are summarized below. Pathological changes of neonatal cardiovascular system after ventricular thalassemia. In the 60s, the pathological changes in the heart of asphyxia children were studied. Burnard et al examined neonatal cardiac death due to asphyxia and found that the weight was greater than the corresponding weight of the control group and most had ventricular
