Preterm birth (PTB) is a leading cause of neonatal morbidity and mortality. With research efforts, the rate of PTB decreased to 11.4% in 2013. Transvaginal ultrasound (TVU) cervical length (CL) screening predicts PTB. In asymptomatic singletons without prior spontaneous PTB (sPTB), TVU CL screening should be done. If the cervix is 20 mm or less, vaginal progesterone is indicated. In asymptomatic singletons with prior sPTB, serial CL screening is indicated. In multiple gestations, routine cervical screening is not indicated. In symptomatic women with preterm labor, TVU CL screening and fetal fibronectin testing is recommended.
早产是新生儿发病和死亡的主要原因。通过研究努力，2013年早产率降至11.4%。经阴道超声（TVU）测量宫颈长度（CL）筛查可预测早产。对于既往无自发性早产（sPTB）的无症状单胎妊娠，应进行TVU CL筛查。如果宫颈长度为20毫米或更短，则建议使用阴道孕酮。对于既往有sPTB的无症状单胎妊娠，建议进行连续CL筛查。对于多胎妊娠，不建议进行常规宫颈筛查。对于有早产症状的女性，建议进行TVU CL筛查和胎儿纤连蛋白检测。
