ABSTRACT
Background Information: The cervical length means the length of the lower part of the uterus (cervix) between external and internal os. The Studies have suggested that the ultrasound assessment of the uterine cervical length is more accurate than the digital examination of the cervix. Trans vaginal ultrasound is a known objective method for assessing cervical length.
Objective: The purpose of carrying out the study was to examine the potential value of the routine measurement of cervical length in singleton low risk pregnancies at 37 weeks in prediction of onset and outcome of labor. Primary outcome was gestational age at delivery and duration of labour. Secondary outcome was need of caesarean for failed progress and post term delivery.
Materials and Methods: It is a prospective observational study which was conducted in the obstetrics and gynecology department of the HMG, Sweidi, Riyadh, Saudi Arabia, which is a 350 bedded multidisciplinary hospital.
Results: Gestational age at delivery was compared in both the groups, 32% (n=41) of the patients delivered within 7 days if the cervical length was shorter than 3 cm as compared to 22%(n=31) but the difference was statistically insignificant. The rate of the post term pregnancy is 30%(n=42) in group B, as compared to 16%(n=21) in group A. Though the rate of post term pregnancy is higher in the patients with more than 3.0 cm cervical length but the difference was not found significant. We found no difference in the first and second stage of the labor and the mode of delivery in two groups.
Conclusion: It was found in the current study that the cervical length measurement does not help in predicting time of delivery. The rate of post term delivery was found insignificantly high in patients having cervical length more than 3.0cm. It was found that the cervical length has no relationship with the duration of labour and mode of delivery. We also conclude that the rate of failed progress of labor cannot be predicted with the measurement of the cervical length alone.
