摘要 目的研究胎儿纤维连接蛋白(fFN)联合宫颈长度检测对先兆早产孕妇发生早产的预测价值。方法选择2010年9月至2011年9月产科门诊定期产检出现先兆早产症状的孕妇共80例,对其阴道分泌物进行了fFN测试,对fFN阳性患者同时联合超声测量宫颈长度,观察其妊娠结局,并与同孕期40例正常孕妇进行比较。结果①观察组80例先兆早产患者中,fFN阳性者42例,阳性率为52.5%,对照组40例孕妇中,fFN阳性者仅为2例,阳性率为5.0%。②fFN对在7 d内、14 d内及孕37周前发生早产的阳性预测值分别为23.8%,33.3%和38.1%,而阴性预测值分别为100%,97.4%和94.7%。③单行fFN预测先兆早产患者孕37周前发生早产的灵敏度为88.9%,特异度为58.1%,阳性预测值为38.1%,阴性预测值为94.7%,二者结合使用,预测孕37周前发生早产的灵敏度为94.4%,特异度为96.2%,阳性预测值为94.4%,阴性预测值为96.2%。结论①fFN阳性对预测早产有一定的临床价值,但其呈阴性时临床意义更大。②fFN联合宫颈长度检测预测早产可以提高阳性预测值。③对无症状的早产低危孕妇不主张常规检测fFN。
