摘要
目的：探讨脐动脉血流检测结合胎心监护在诊断脐带绕颈中的应用价值。方法：对５１６例单胎头位孕足月无合并症及并发症孕妇进行脐血流检测，并对１８３例脐血流诊断脐带绕颈者进行催产素激惹试验（ＯＣＴ）。结果：脐血流检测结合ＯＣＴ诊断脐带绕颈准确率和特异性显著高于单纯脐血流组（Ｐ＜０．００５）。脐带绕颈者脐血流Ｓ／Ｄ值波动于正常范围。绕颈紧组胎心宫缩图（ＣＴＧ）主要表现频发轻度可变减速（ＶＤ）及混合性减速图型其胎儿窘迫发生率显著高于绕颈松组和无绕颈组（Ｐ＜０．００５）。结论：脐血流检测结合ＯＣＴ可提高诊断脐带绕颈的符合率，ＣＴＧ对判断脐带绕颈松紧和胎儿预后具有重要的临床应用价值。
Objective:To evaluate the clinical value of umbilical arterial blood flow and fetal heart rate monitoring in diagnosis of umbilical cord around the fetal neck(UCAN).Methods:Five hundred sixteen cases,with 37～41 week gestation,single fetus,single fetus,head presentation normal pregnancy were detecting for umbilical arterial blood flow.To the 183 cases diagnosed as UCAN,oxytocia challenge test(OCT) was made before delivery.Results:The accurate rate and specificity of UCAN,diagnosed with both methods were signiticantly higher than those with umbilical blood flow alone( P <0.005).S/D ratio of umbilical arterial blood flow was within normal range for patients of UCAN.In “taut UCAN” group cardiotocograghy(CTG) showed mainly frequent light variable deceleration(VD) and mixed deceleration.Incidence of fetal distress in “taut UCAN” group was significantly higher than that in “slack UCAN” and “no UCAN” group( P <0.005).Conclusions:Fetal umbilical blood flow measurement in combination with OCT increases the accuracy in diagnosis of UCAN and CTG is important in judging the tension of the cord around the fetal neck.
