324 participants in 2 patient groups

Coached maternal pushing via ultrasound (US)

Experimental group

Description:

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.

Treatment:

Other: Visual biofeedback using transperineal ultrasound (TPUS)

Traditional coached maternal pushing

No Intervention group

Description:

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.
