Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Coached maternal pushing via ultrasound (US)

The study group, will have coached pushing using trans-perinal ultrasound (US) performed by the midwife during the active stage of labor, and after diagnosis of complete dilatation. Further, if not delivered within 2 hours of complete dilatation, a third coaching will be conducted. The coaching process in each will be performed for 10 minutes and for at least 3 contractions.

In the study group the women will observe the fetal head movements on the screen in front of her.

Group Type EXPERIMENTAL

Visual biofeedback using transperineal ultrasound (TPUS)

Intervention Type OTHER

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

Traditional coached maternal pushing

The control group will have the traditional coached pushing (vaginal) performed by a midwide during the active stage of labor, and after diagnosis of complete dilatation. Further, if not delivered within 2 hours of complete dilatation, a third coaching will be conducted. The coaching process in each will be performed for 10 minutes and for at least 3 contractions The women in the controlled group will have the vocal coaching of the midwife during the contractions.
