| 【】目的：探讨超声联合测定脐动脉(UA)、脑中动脉(MCA)的阻力指数(RI)对胎儿窘迫的预测价值。方法：选取2014年6月月至2017年6月我院确诊治疗的胎儿窘迫孕妇100例作为窘迫组,同期选取正常孕妇100例作为对照组,所有孕妇均给予超声测定UA、MCA的RI,并通过计算其比值(UA/MCA的RI)。结果：窘迫组UA的RI及UA/MCA的RI水平明显高于对照组,窘迫组MCA的RI水平明显低于对照组,差异有统计学意义(P<0.05)；ROC曲线结果显示,在预测胎儿窘迫的敏感度、特异度、准确度方面,UA的RI以>0.68为临界值时,分别为84.00%、82.00%、83.00%,MCA的RI以<0.87为临界值时,分别为88.00%、84.00%、86.00%,UA/MCA的RI以>0.70为临界值时,分别为96.00%、94.00%、95.00%,UA/MCA的RI明显高于UA的RI、MCA的RI,差异有统计学意义(P<0.05),UA的RI和MCA的RI基本相同,差异无统计学意义(P>0.05)。结论：超声测定UA、MCA的RI可作为预测胎儿窘迫的重要参考指标,且联合测定并以其UA/MCA的RI预测时,具有更为良好的预测敏感性、特异性、准确性,值得临床作进一步推广。 |

| Abstract: |
| 【S】objective:To discuss the predictive value of umbilical artery (UA) combined middle cerebral artery (MCA) resistance index (RI) determination by ultrasonography for fetal distress.Methods: 100 pregnant woman with fetal distress were selected as distress group from June 2014 to June 2016 in our Hospital,100 normal pregnant woman were selected as control group at the same time,UA,MCA"s RI were determinated by ultrasonography in all pregnant woman,and it calculate their ratio (UA/MCA"s RI).Results:The UA"s RI,UA/MCA"s RI levels of distress group were significantly higher than those of control group,the MCA"s RI level of distress group was significantly lower than that of control group, the difference was statistically significant (P < 0.05).The ROC curve results showed that,in the sensitivity, specific,accuracy degrees of predicting fetal distress,the UA"s RI for > 0.68 as the critical value,they were 84.00%, 82.00%, 83.00%,the MCA"s RI for < 0.87 as the critical value,they were 88.00%, 84.00%, 86.00%,the UA/MCA"s RI for > 0.70 as the critical value,they were 96.00%, 94.00%, 95.00%,the UA/MCA"s RI were significantly higher than those of the UA"s RI,the MCA"s RI,the difference was statistically significant (P < 0.05),the UA"s RI,the MCA"s RI were basically the same, there was no statistically significant difference (P > 0.05).Conclusions:UA, MCA resistance index determination by ultrasonography can be used as the important reference indexs for predicting fetal distress,their combined determination and as the UA/MCA"s RI to predict,it has the better sensitivity, specificity, accuracy of prediction,it’s worth for further clinical promotion. |
