NCT04651309

Brief Summary

Assessment of labor progress via digital exams is considered the standard of care in most delivery rooms. However, this method can be stressful, painful and imprecise and multiple exams increase the risk for chorioamnionitis. Trans-perineal ultrasound (TPUS) was found to be an objective noninvasive way to monitor labor progress. The study aim is to investigate whether, in nulliparous women, the use of TPUS during labor can reduce the number of vaginal exams and the incidence of chorioamnionitis.

Outcome Measures

Primary Outcomes (2)

  • Fever and infection rates in each of the study arms

    Intrapartum and post partum fever rates will be evaluated in both the study and the control groups.

    From admission to hospital for labor until 2 week post-partum

  • Number of digital exams in each of the study arms

    The number of digital exams will be counted in each of the study arms

    From admission to hospital until delivery

Study Arms (2)

Ultrasound group

OTHER

Labor progress assessed by US, avoiding digital exams as much as possible;

Other: Transperineal Ultrasound

Control group

NO INTERVENTION

Labor progress assessed according to the regular protocol

Interventions

The ultrasound examination will be conducted using the technique described by Hassan et al (2013). Briefly, transperineal ultrasound images are obtained by placing a covered transducer between the labia below the symphysis pubis. Small lateral movements of the probe are then made to align the ultrasound beam in a midsagittal orientation to include the whole cervical length after which the probe is rotated 90 degrees in order to measure the cervical dilatation. The probe is rotated up and down until the echogenic circle of the cervix is seen. Please note that this technique is widely used within the delivery room and that the ultrasound machine that will be used is frequently used within the delivery room.
