Introdution: Our aim was to determine the potential value of a routine ultrasound examination in low-risk pregnancies at 37 to 41 weeks for the prediction of likely outcome of labour, including the risk of prolonged pregnancy and the need for Caesarean section for failed induction or lack of progress in labour. Aims and Objectives of the Study: To assess cervical length in the subjects attending antenatal OPD with a singleton gestation with vertex presentation between 37 to 41 weeks and to study the likely outcome of labour. Material and Methodology: Women having gestational age of 37 to 41 weeks with cephalic presentation, intact membranes, live fetus and not labouring were included in the study. Conclusion: This study has demonstrated that measurement of CL at term can be used to determine the likelihood of prolonged pregnancy and the risk of emergency CS for failure to progress or failed induction of labour.
