A Study to Evaluate Ultrasound Scans to Measure Cervical Dilation and Effacement in Labor

Overview

About this study

The purpose of this study is to test the accuracy and comfort of self-directed ultrasound imaging of cervical dilation and length in participants undergoing induction of labor. The study will assess correlation of cervical measurements between self-directed imaging and experienced provider digital cervical examinations. Experienced providers performing digital cervical examinations will be blinded to ultrasound images and measurements. Participants will be randomized to undergoing digital cervical examination or ultrasound imaging as initial modality to assess cervical measurements.
