通过较大样本比较胎儿纤维结合素（ＦＦＮ）和Ｂｉｓｈｏｐ评分对预测足月孕妇引产的意义。对象为产科有引产指征和择期引产的足月孕妇共１０５例。方法：引产当日行阴道内诊前常规准备，用生理盐水３ｍｌ冲洗宫颈外国滞留１０分，抽取冲洗后的盐水送检ＦＦＮ水平。临床检查得出Ｂｉｓｈｏｐ评分。结果：１０５例受试者中，剖宫产１３例，≤２４小时引产成功５８例，＞２４小时引产成功３４例。ＦＦＮ预测孕妇引产成功的特异性为９０％，敏感性为７７％，阳性和阴性预测值分别为８７％和８１％。Ｂｉｓｈｏｐ评分预测孕妇引产成功的相应指标为７２％、６８％、７９％和５９％。结论：胎儿纤维结合素作为独立的客观标志预测足月孕妇引产是否成功优于Ｂｉｓｈｏｐ评分。
Fetal fibronectin (FFN) and Bishop scores were compared for predicting labor induction in term pregnant women. A total of 105 obstetric women with full-term indications for induction of labor and elective induction of labor. Methods: The day before induction of vaginal discharge routinely prepared before vaginal discharge, with 3ml of normal saline rinse foreign cervical retention of 10 points, after the extraction of rinsed saline for FFN levels. The clinical examination yields a Bishop score. Results: Among the 105 subjects, 13 cases were cesarean, 58 cases were successful induction of labor ≤24 hours, and 34 cases were successful in induction of labor within 24 hours. FFN predicts the specificity of pregnant women for successful induction of labor is 90% with a sensitivity of 77% and positive and negative predictive values of 87% and 81%, respectively. Bishop scores predict the success of pregnant women induction of the corresponding indicators of 72%, 68%, 79% and 59%. CONCLUSION: Fetal fibronectin is an independent objective marker for predicting the success of induction of labor in term pregnant women over Bishop’s score.
