【摘要】 目的:探讨新生儿窒息母、脐血中红细胞参数及红细胞电泳指标的变化。方法:胎儿娩出后迅速进行1 min的Apgar评分和脐血pH值检测,作为新生儿窒息的诊断标准;选择产后出现急性胎儿窘迫孕妇60例,其中出现新生儿窒息的30例为窒息组,娩出后胎儿正常的30例为窘迫组;另外选择正常足月孕妇30例为对照组。留取母血、脐血,检测红细胞压积(HCT)、平均红细胞体积(MCV)、红细胞体积分布宽度(RDW)等红细胞参数,并进行红细胞电泳等红细胞流变学指标检测。结果:窒息组脐血pH值显著低于其他两组,窒息组脐血与窘迫组和对照组相比MCV 及RDW值明显增高,红细胞电泳时间延长,红细胞电泳长度与迁移率明显降低; 母血MCV、RDW、红细胞电泳能力等红细胞流变学指标三组之间差异无统计学意义。结论:缺氧窒息可致新生儿脐血红细胞参数、红细胞电泳等流变性指标异常。

Results: PH values in asphyxia neonatorum group were lowered significantly than that of other two groups.Compared with that of control and fetal distress groups,values of MCV and RDW elevated,the time of erythrocyte electrophoresis extended,erythrocyte electrophoretic length and mobility decreased significantly in umbilical cord blood of asphyxia neonatorum group.There was no statistically significant difference in those erythrocyte rheology indicators of maternal blood among three groups.Conclusion:Hypoxia and asphyxia can result in changes of erythrocyte rheology in umbilical cord blood from cases subjected to asphyxia neonatorum,which provide an experimental basis for the therapy of asphyxia neonatorum.
