摘要

导言:在全球范围内,早产的流行率一直在上升,短子宫颈与早产密切相关。然而,研究表明,当它在妊娠中期早期被发现时,可以采取预防措施来防止妊娠丢失。材料和方法:本前瞻性队列研究在伊巴丹大学学院医院(UCH)进行的18至24周的妊娠中期异常超声扫描的孕妇中进行。经阴道行超声测量宫颈长度,随访至分娩。结果:177名年龄在21岁到44岁之间的孕妇被招募参加这项研究。妊娠中期宫颈短的发生率为7.9%。早产率为14.1%,早产率与宫颈长度短有统计学意义。采用<2.5 cm宫颈长度临界值对早产的阳性预测值为44%,阴性预测值为97.3%。结论:超声检查发现宫颈短长度导致早产的发生率在联合医院产前门诊的妇女中具有显著性,且与既往早产、既往早产胎膜早破等危险因素有显著相关性。

Predictive value of cervical length measurement on transvaginal ultrasonography in determination of preterm delivery in a Nigerian South Western Tertiary Hospital
Introduction: There has been an upsurge in the prevalence of preterm delivery globally and short cervix has been strongly associated with it. However, studies have shown that when it is detected early in mid-second trimester, preventive measures could be taken to forestall pregnancy loss. Materials and Methods: This prospective cohort study was conducted among pregnant women who presented for mid-trimester anomaly ultrasound scan between 18 and 24 weeks at the University College Hospital (UCH), Ibadan. The cervical length was measured with ultrasound machine through the transvaginal route and the patients were subsequently followed up till delivery. Results: One hundred and seventy-seven pregnant women with an age range between 21 and 44 years were recruited for the study. The incidence rate of mid-pregnancy short cervical length among the patients was 7.9%. The preterm delivery rate was 14.1%, and the association between it and short cervical length was statistically significant. The positive predictive value for preterm delivery when the <2.5 cm cervical length cut-off was used was 44%, the negative predictive value was 97.3%. Conclusion: The incidence of preterm delivery due to ultrasonographically detected short cervical length was significant among the women attending antenatal clinic in UCH, and there was a significant association with some of the risk factors such as previous preterm delivery and previous preterm premature rupture of membranes.
