RESUMO
Background: Preterm birth is a major challenges faced by obstetricians worldwide during their practice. Preterm birth is one of a leading direct cause of neonatal death (27%) and more than one million preterm newborns die annually due to various complications. This study done to look for diagnostic efficacy of sonographic cervical length to predict preterm labour. Methods: A prospective study comprised of a total of 132 pregnant women with a singleton foetus with symptoms of preterm labour. Sonographic trans-cervical length measurement taken in all patients. Results: Out of which 17 patients were lost during follow up, 3 patients develop premature rupture of membrane. Hence, a study was conducted over 112 patients. Among these 62 patients went in preterm labour and 50 patients delivered at term. For predicting preterm delivery, sensitivity, specificity, positive and negative predictive value of cervical length was 82.2%, 74%, 79.6% and 77%. Conclusion: Sonographic cervical length is a good predictor. Patients with reduced cervical length are more likely to deliver preterm.
