Trial Summary

What is the purpose of this trial?

This is a pilot study to test the accuracy and comfort of self-directed ultrasound imaging of cervical dilation and effacement in pregnant women undergoing induction of labor. The study will assess correlation of cervical measurements between self-directed imaging and experienced provider digital cervical examinations.

Participant Groups
2Treatment groups
Experimental Treatment
Group I: Ultrasound Assessment performed firstExperimental Treatment3 Interventions
Ultrasound imaging will be first taught by an experienced RN, then self-performed by the participant in the presence of junior obstetrics and gynecology resident and the RN. The junior resident will ensure the ultrasound device is functioning properly and the images are saved. In this group, the participant-performed imaging assessment is done first, followed by a digital cervical exam performed by an experienced senior obstetrics and gynecology resident.
Group II: Digital Cervical Assessment performed firstExperimental Treatment3 Interventions
A digital cervical exam will be performed by an experienced senior obstetrics and gynecology resident, using index finger and middle finger to measure the dilation and thickness of the cervix. This is the gold standard measurement utilized to assess the labor course. In this group, the digital cervical exam is done first, followed by a participant-performed ultrasound imaging assessment of the cervix.
