胎心监护联合脐血流监测对早期诊断胎儿宫内窘迫的意义

Value of umbilical blood flow measurement combined with fetal monitoring for early diagnosis of fetal distress

目的探讨胎心监护联合脐血流监测在早期诊断胎儿宫内窘迫中的意义。方法选取咸阳市妇幼保健院2010年3月至2013年12月收治的160例产妇为研究对象,所有产妇孕周为34～41周。根据胎心监护和脐血流监测结果,将160产妇分为4组。甲组为胎心监护正常、脐血流监测正常;乙组胎心监护正常、脐血流监测异常;丙组胎心监护异常、脐血流监测正常;丁组胎心监护异常、脐血流监测异常。对比4组产妇分娩前、分娩时发生胎儿宫内窘迫的例数,为以后早期诊断胎儿宫内窘迫提供指导。结果 4组产妇胎儿窘迫发生率均不相同,其中甲组胎儿宫内窘迫率为27.2%（31/114）;丁组胎儿宫内窘迫例率为66.7%（6/9）;乙组和丙组胎儿宫内窘迫率分别为33.3%、37.5%,甲组与其他3组胎儿宫内窘迫发生率比较,差异有统计学意义（P〈0.05）。结论胎心监护联合脐血流监测早期诊断胎儿宫内窘迫的正确率高于单独测定胎心监护或脐血流,为胎儿预后提供了可靠的依据,值得临床上进一步推广。

Objective To investigate the value of umbilical blood flow measurement combined with fetal monitoring for early diagnosis of fetal distress .Methods A total of 160 women with 34-41 weeks pregnant from Mar .2010 to Dec .2013 were selected and divided into four groups according to the results of fetal heart rate monitoring and umbilical blood flow measurement .Both of the two results in the group A were normal .Group B had normal fetal heart rate but abnormal umbili -cal blood flow .Group C had abnormal fetal heart rate but normal umbilical blood flow .Both of the two results were abnormal in group D .Numbers of fetal distress were compared during pregnancy and delivery among the four groups .Results The in-cidence of fetal distress in group A ,B ,C and D was 27 .2% （31/114） ,33 .3% （7/21） ,37 .5% （6/16） and 66 .7% （6/9） re-spectively .And the incidence in group A was significant lower than other three groups （P〈 0 .05） .Conclusion The com-bined detection of umbilical blood flow and fetal heart rate has higher accuracy rate on diagnosis for fetal distress compared with detecting these two indicators alone ,which provide a reliable basis for the prognosis of the fetus with fetal distress ,and could be worthy of further promotion in clinical practice .
