Abstract

Background: The cervix and the changes it undergoes in pregnancy play an important role in the initiation and progress of labor. Materials and methods: The period of study was from January to December 2022 for a period of one year. A total of 370 low-risk primigravid antenatal mothers were included in the study. Cervical length was measured transvaginally at 37 weeks. Results and analysis: The average length of the cervix ranged from 1 to 5 cm. The cervical length was <3 cm in 48.3% of patients and >3 cm in 51.7% of patients. Among the 370 primigravid mothers, 248 were delivered by labor natural (67%), 97 by lower segment cesarean section (LSCS) (26.2%), and 25 by instrumental delivery (3.8%). Patients with a cervical length of <3 cm had a shorter duration of labor when compared to patients with a cervical length of >3 cm. The need for induction and the induction delivery interval was less in patients with shorter cervical length. Conclusion: Ultrasonography (USG) is one of the key investigations in antenatal care. Transvaginal cervical length measurement is a useful tool to predict favorable outcomes in labor induction and the progress of labor. Hence routine measurement of transvaginal cervical length in all the antenatal mothers will help the treating obstetrician in planning the management of delivery.
