妊娠中晚期脐血流检测的临床意义

Clincal experience of fetal umbilical artery blood flow examination

目的:探讨妊娠中晚期脐血流S／D值异常者的围产儿结局,以及宫内治疗效果与围产儿结局的关系。方法:回顾性分析2001年6月~2003年12月在我院分娩,并在妊娠34周前进行脐血流检查的产妇共103例,按S／D值异常与否进行分组,并比较两组资料。结果:①妊娠34周前脐血流S／D值异常组不良围产儿结局的发生率明显升高,尤其是羊水异常和胎儿窘迫的发生率,差异有显著性(P【0.01)。②经过宫内治疗脐血流S／D值恢复正常者不良围产儿结局的发生率明显降低,其中羊水异常和胎儿窘迫的发生率,差异有显著性(P【O.01)。结论:妊娠中晚期脐血流检测能早期发现胎儿宫内缺氧情况,并能动态观察临床治疗情况,而且对围产儿结局有很好的监测作用。

Objective: To study the perinatal outcome in patients with abnormal umbilical artery blood flow and the relationship between the perinatal outcome and the efficacy of intrautery therapy. Methods: Patients whose umbilical artery blood flow exanlined before 34 gestational weeks during 2001.6 - 2003.12 were reviewed and analyzed. Results: (1)The rate of poor perinatal outcomes, especially the rate of fetal distress, in abnormal umbilical artery blood flow group was significantly hyigher than those in control groups (P<0. 01).(2)The incidence of poor perinatal outcomes in patients whose umbilical artery blood flow turned to normal after intrautery therapy was signihcantly lower than those still abnormal. Conclusion: Umbilical artery blood flow examination can find fetal distress early in order to deal with in time to improve fetal well being. It can also observe the efficacy of the intrautery therapy
