About this study

Official title: The Effect of Ultrasound Guided Visual Biofeedback Performed by Midwifes on the Duration of the Active Second Stage of Labor, a Randomized Controlled Trial

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.

Being tested
Visual biofeedback using transperineal ultrasound (TPUS)

Study groups in NCT06857552
Study groupRoleWhat they receive
Coached maternal pushing via ultrasound (US)ExperimentalThe 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.
Receives: Other: Visual biofeedback using transperineal ultrasound (TPUS)
Traditional coached maternal pushingNo interventionThe 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.
