第40卷第4期2023年8月姚轶等NST联合脐动脉S/D值预测子痫前期胎儿宫内窘迫·93·NST联合脐动脉S/D值预测子痫前期胎儿宫内窘迫姚轶许荣华马红星（安徽省妇幼保健院妇产科，安徽合肥230001）摘要目的：探讨胎心监护（NST）联合胎儿脐动脉血流收缩期峰值S/D值对子痫前期宫内窘迫胎儿的预测价值。方法：选取99例子痫前期患者，分为宫内窘迫组和无宫内窘迫组。记录胎心监护指标和脐动脉血流动力学；Kappa一致性分析应用价值。结果：宫内窘迫组患者胎儿的S/D值、RI和PI值均明显较高，NST例数明显较少，无反应型NST例数明显较多（P＜0.05）；联合诊断的灵敏度为0.967，特异度为0.986，Kappa值为0.968。结论：临床可通过联合诊断预测胎儿宫内窘迫，对高风险人群进行及时干预，确保母婴安全。关键词胎心监护；子痫前期；胎儿宫内窘迫；S/D值；应用价值PredictivevalueofNSTcombinedwithumbilicalarteryS/DvalueforfetalintrauterinedistressinpatientswithpreeclampsiaYaoYi;XuRonghua;MaHongxing（DepartmentofObstetricsandGynecology,AnhuiMaternalandChildHealthHospital,Hefei230001,Anhui,China）AbstractObjective:Toexplorethepredictivevalueofnon-stresstest(NST)combinedwithS/Dvalueforfetalintrauterinedistressinpreeclampsiapatients.Methods:Atotalof99patientswithpreeclampsiawereenrolledanddividedintodistressgroupandnon-distressgroup.Thefetalheartratemonitoringindexesandumbilicalarteryhemodynamicswererecorded,andtheirapplicationvaluewasanalyzedbyKappaconsistencytest.Results:Comparedwithnon-distressgroup,fetalS/Dvalue,RIandPIweresignificantlygreater,numberofNSTcaseswassignificantlyless,andnumberofcaseswithnonreactiveNSTwassignificantlymoreindistressgroup(P<0.05).Thesensitivity,specificityandKappavalueofcombineddetectionwere0.967,0.986and0.968,respectively.Conclusion:Clinically,combineddiagnosiscanbeappliedtopredictfetalintrauterinedistress.Timelyinterventioncanbetakenforhigh-riskgroupstoensurematernalandneonatalsafety.KeywordsFetalheartratemonitoring;Preeclampsia;Fetalintrauterinedistress;S/Dvalue;Applicationvalue子痫前期能够导致产妇或胎儿死亡率升高，也是造成剖宫产手术的主要原因之一[1]。患者术中常因小动脉痉挛出现血管破裂等状况，严重时甚至导致母婴死亡[2-3]...
