Abstract

Objectives: To evaluate the clinical use of transvaginal ultrasonographic cervical length measurement for predicting successful labor induction at term in women with strictly unfavorable cervices. Materials and Methods: Seventy four women at term with maternal and fetal indications for labor induction were included in the study. All women had singleton pregnancies in vertex presentation and a Bishop score of ²4 in the presence of closed cervices without evidence of uterine contractions. Fifty μcg sublingual misoprostol every four hours up to a maximum six doses was commenced. Cervical length was measured by transvaginal ultrasound, and receiver operator curve characteristics were analyzed for predictability of cesarean delivery and induction failure as judged on the basis of no delivery or no uterine contractions within 24 hours. Results: Fourteen cesarean deliveries (18.9%) and seven induction failures (9.4%) were diagnosed. Using the optimum cutoff value of 30 mm as a threshold of cervical length for the prediction of induction failure, a sensitivity of 85.7%, a specificity of 44.3%, a positive predictive value of 15% and a negative predictive value of 96.4% were obtained. Using the optimum cut-off value of 30 mm as a threshold of cervical length for the prediction of cesarean delivery, a sensitivity of 85.7%, a specificity of 43.3%, a positive predictive value of 26% and a negative predictive value of 92.9% were obtained. The cesarean section rate was 26.1% for the women who had a cervical length ³30 mm, while it was 7.1% for the women with a cervical length ²30 mm (p=0.04). Fetal birth weight was a better predictor of failed induction (Area Under the Curve [AUC]: 0.65) followed by cervical length (AUC: 0.63). Discussion: Although cervical length measurement has some predictive value, AUC analysis revealed that it is far from being an ideal test for detecting induction failures. 30 mm can be a good clinical cut-off value to predict cesarean deliveries in women with misoprostol induced labor

Özet

Amaç: Uygunsuz servikse sahip kadınlarda termde doğum indüksiyonunun başarısını öngörmede transvajinal ultrasonografik olarak servikal uzunluk ölçümünün klinik öneminin değerlendirilmesi. Materyal ve Metot: Çalışmaya maternal ve fetal endikasyonlar nedeniyle doğum indüksiyonu uygulanan yetmiş dört ardışık term kadın dahil edildi. Tüm kadınlar verteks prezentasyonunda tekil gebeliğe sahipti ve uterin kontraksiyonlar olmaks›z›n, kapalı serviks varlığında, Bishop skoru ²4 idi. Dört saatte bir 50 μcg olmak üzere maksimum altı doz sublingual mizoprostol uygulandı. Transvajinal ultrasonografi ile servikal uzunluk ölçümü gerçekleştirildi. Sezaryen doğum oranları ve 24 saat içerisinde doğumun gerçekleşmemesi ya da uterin kontraksiyonların indüklenememesi şeklinde tanımlanan başarısız indüksiyon oranlarının öngörülmesini belirlemek üzere ROC analizi yapıldı.Sonuç: On dört sezaryen doğum (%18.9) ve yedi başarısız indüksiyon (%9.4) tanısı konuldu. Başarısız indüksiyonun öngörülmesinde optimum servikal uzunluk eşik değeri olarak 30 mm kullanıldığında %85.7 duyarlılık, %44.3 özgüllük, %15 pozitif prediktif değer ve %96.4 negatif prediktif değer elde edildi. Sezaryen doğumun öngörülmesinde optimum servikal uzunluk eşik değeri olarak 30 mm kullanıldığında %85.7 duyarlılık, %43.3 özgünlük, %26 pozitif prediktif değer ve %92.9 negatif prediktif değer elde edildi. Servikal uzunluğu ³30 mm olan kadınlarda sezaryen oranı %26.1 iken
