The efficacy of regular cervical examinations in detecting preterm labor, as well as possible risks, was studied for 133 preterm labor patients who had received regular cervical examinations as part of a preterm birth prevention program. When compared to all other patients experiencing preterm labor during the study period, the rates of preterm premature rupture of the membranes, chorioamnionitis, and postpartum endomyometritis were not increased. For 95 patients with preterm labor within 7 days of a routine cervical examination, labor onset was not temporally associated with the preceding examination. Preterm labor was diagnosed in 18 asymptomatic patients (18.2%) when the weekly examination revealed cervical change. Routine cervical exams, therefore, did not increase morbidity, and for some patients identified preterm labor before symptoms appeared.
对133名接受定期宫颈检查作为预防早产计划一部分的早产患者，研究了定期宫颈检查在检测早产以及可能风险方面的效果。与研究期间所有其他早产患者相比，胎膜早破、绒毛膜羊膜炎和产后子宫内膜炎的发生率并未增加。对于95名在常规宫颈检查后7天内发生早产的患者，分娩发作与之前的检查在时间上无关联。当每周检查发现宫颈变化时，18名无症状患者（18.2%）被诊断为早产。因此，常规宫颈检查并未增加发病率，并且对一些患者而言，在症状出现前就识别出了早产。
