RESUMO
Cervical length (by transvaginal sonography) was compared to Bishop's score (by digital examination of cervix) for prediction of pre-term birth in women with pre-term labour. The study group was 100 women with a singleton pregnancy with pre-term labour between 26-36 weeks' gestation. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of cervical lengthâ≤2.5 cm ( by TVS) to predict delivery within 48 h and 7 days of admission were 62.5%, 89.5%, 65.2%, 88.3%, and, 60.0%, 96.9%, 91.3%, 81.8%, respectively. Similar values of Bishop's scoreâ≥5 were 62.5%, 85.52%, 57.69%, 87.83%, and, 62.8%, 93.8%, 84.6%, 82.4%, respectively. To conclude, both Bishop's scoreâ≥5 and reduced cervical length ofâ≤2.5 cm (by TVS) can predict the risk of pre-term delivery within 48 h or 7 days.

The study group consisted of 100 women with a singleton pregnancy with pre-term labour between 26-36 weeks' gestation. Cervicovaginal secretions were collected for HCG assay and cervical length was measured by transvaginal sonography (TVS). These parameters were analysed to predict pre-term birth. The pre-term delivery rate was 55%; 24% delivered within 48 h and 11% within 7 days of admission. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of cervical length
