计算机分析胎心率监护与围产儿预后的关系

Relationship between Parameters of Computerized Cardiotocography and Perinatal Outcomes

目的 :探讨计算机分析电子胎心率监护 (EFM)与围产儿预后的相关性。方法 :对 2 935份胎心监护曲线 (CTG)的计算机评分及其临床资料做回顾性分析。按不同的CTG评分分 5组 :≥ 8分组 ,7分组 ,6分组 ,5分组和≤ 4分组。分别对各组新生儿出生后记录Apgar评分、羊水量、羊水污染度及围产儿预后不良发生率等项进行统计对比。结果 :CTG评分 7分组和≥ 8分组各项对比无显著差异 (P >0 .0 5 ) ;6分组与≥ 7分组相比 ,新生儿Apgar低评分有显著差异 (P <0 .0 5 ) ,羊水污染及围产儿预后不良发生率有极显著差异 (P <0 .0 1) ;5分组与≥ 6分组相比 ,羊水污染、Apgar低评分及围产儿预后不良发生率各项对比均有极显著差异 (P <0 .0 1) ;≤ 4分组 ,围产儿预后全部不良 ,各项指标与其他组相比均有极显著性差异 (P <0 .0 1)。结论 :计算机分析电子胎心率监护 (EFM)

Objective: To investigate the relationship between parameters of computerized cardiotocography (CTG) and perinatal outcomes, Methods: A retrospective anlysis was made in 2935 cases of computerized CTG They were divided into five groups according to different CTG scores:≥8 scores′ group,7 scores′ group, 6 scores′ group,5 scores′ group and, ≤4 scores′ group. Statistically contrasted the neonatal Apgar scores, volume and colour of amniotic fluid and the incidence of bad perinatal outcomes. Results: There was little difference between the 7 scores′ group and ≥8 scores′ group in any contrast(P>0.05). Between the 6 scores′ group and ≥7 scores′ groups, there were significant differences in neonatal Apgar scores(P<0.05),amniotic fluid colour and incidence of bad perinatal outcome (P<0.01).Between the 5 scores′ group and the ≥6 scores′ groups, there were also significant differences in the three contrasts(P<0.01). In the ≤4 scores′ group, all the perinatal outcomes were bad, and each contrast was significantly different from it in other groups(P<0.01).Conclusion:The parameters of computerized cardiotocography is a better predictor for perinatal outcome.
