Brief summary

The goal of this randomized controlled trial is to investigate whether using of coached sonographic pushing will decrease the length of the second stage of labor and the rate of operative deliveries. Researchers will compare women who undergo the traditional coached pushing to women who undergo visual biofeedback coached pushing.

Interventions

OTHERVisual biofeedback using transperineal ultrasound (TPUS)

The intervention (study) arm will recieve coached maternal pushing via transperineal ultrasound (US) with visual biofeedback
