Transvaginal ultrasonographic cervical length in predicting induction to delivery interval
Author(s): Anuradha K Sheshappanavar and Nandini D
Abstract: A recent study well designed blinded multicenter study of Maternal Fetal Medicine Units Network of the National Institute of Child Health and Human Development on TVU in patients with a history of PTB <23 weeks demonstrated that the best predictive accuracy was achieved with serial TVUs, and including the shortest cervix ever after spontaneous or transfundal pressure elicited changes. Transvaginal cervical length was measured in mm with the standard longitudinal view of the cervix after asking patient to empty bladder using PHILIPS HD 5 machine. The image was enlarged so that the cervix occupies at least two-third of the image and external OS and internal OS are well seen. Three consecutive cervical images will be obtained and three separate readings of cervicallength was taken and then average cervical length in mm will be considered for the study. After sonography, modified Bishop’s score was determined by digital examination. Transvaginal Ultrasonographic Cervical Length at >23 had highest validity in predicting the success of labour.
