为研究脐血血小板聚集与胎儿窘迫和新生儿窒息的关系,探讨血小板聚集功能在新生儿窒息发病中的作用,对窒息新生儿进行脐血体外血小板聚集率（PAgT）测定和血小板计数,并与正常新生儿对照。结果显示,窒息新生儿脐血血小板聚集率明显高于正常对照组,（P<0.05）,血小板计数与对照组比较差异无显著（P>0.05）。因此,窒息新生儿脐血血小板聚集率升高,血小板聚集功能在新生儿窒息发病中起重要作用。 To investigate the relationship between cord blood platelet aggregation and fetal distress and neonatal asphyxia, explore the role of platelet aggregation in the pathogenesis of neonatal asphyxia, investigate cord blood platelet aggregation rate (PAgT) and platelet count in neonates with asphyxia Normal neonatal control. The results showed that asphyxial neonatal cord blood platelet aggregation rate was significantly higher than the normal control group, (P <0.05), platelet count compared with the control group no significant difference (P> 0.05). Therefore, asphyxial neonatal cord blood platelet aggregation rate increased, platelet aggregation function plays an important role in neonatal asphyxia.
