摘要
目的:分析FFN和B超测宫颈长度联合检查预测早产的临床价值。方法:于本院产科门诊定期产检的孕妇中选择82例有先兆早产症状的单胎孕妇为研究对象,所有孕妇均行FFN检测和宫颈长度B超测量,分别以FFN阳性和宫颈长度≤30 mm为判断孕妇早产的依据,对比分析FFN检测、B超测宫颈长度及两者联合检查预测早产的临床价值。结果:本组82例先兆早产孕妇中,共36例发生早产,早产发生率为43.90%(36/82)。FFN检测预测早产的敏感性为80.56%,特异性为89.13%,阳性预测值为85.29%,阴性预测值为85.42%;B超测量宫颈长度依次为76.32%、78.26%、72.97%、80%;而两者联合检测依次为97.22%、91.30%、89.74%、97.67%。FFN和B超测宫颈长度联合检查预测早产的敏感性、特异性、阳性预测值和阴性预测值均高于两者单独检查的预测,且在敏感性及阴性预测值上,差异具有统计学意义(P<0.05)。结论:FFN和B超测宫颈长度联合检查预测早产能有效提高两者单独预测的敏感性、特异性、阳性预测值和阴性预测值,从而提高早产预测的准确率。
Objective：To analyze the clinical value of FFN and B ultrasound cervical length measurement joint inspection of predict premature.Method：82 cases of pregnant women with aura singleton pregnant women in preterm labor symptoms in our hospital maternity department regular prenatal were chosen as the research object, and all pregnant women underwent FFN detection and B ultrasound cervical length measurement, and the cervical length with FFN positive and cervical length respectively 30 mm or less was used as the basis of labor.The FFN detection, B ultrasonic measuring cervical length and the joint inspection to predict the clinical value of premature were compared and analyzed.Result：82 cases of aura preterm pregnant women, a total of 36 cases of preterm delivery, the incidence of premature birth were 43.90%（36/82）.FFN detection forecast preterm birth a sensitivity of 80.56%,specificity of 89.13%, positive predictive value was 85.29%,and negative predictive value was 85.42%; B ultrasound measurement of cervical length was respectively 76.32%,78.26%,72.97%,78.26%.The joint detection was 97.22%,91.30%,89.74%,91.30% in turn.FFN,B ultrasound cervical length measurement and joint inspection to predict premature sensitivity,specificity,positive predictive value and negative predictive value were higher than the two separate check forecast, and on the sensitivity and negative predictive value the difference statistically significant（P〈0.05）.Conclusion：FFN and B ultrasound cervical length measurement joint inspection preterm labor can effectively improve both the single prediction of sensitivity, specificity, positive predictive value and negative predictive value, thus improve the premature forecast accuracy.
