Pushing and Manual Perineal Protection Techniques

Pushing technique: Rest will be encouraged between uterine contractions. With the onset of uterine contraction, women will be instructed to breathe normally. They will then be instructed to take a deep breath and hold (closed-glottis), and push down strongly for as long as possible (up to 10 seconds). After pushing effort, normal breathing will be encouraged, then the same pushing instruction will be repeated again. Fetal expulsion: The expulsion rate of the fetal head will be controlled by light pressure applied on the fetal occiput. Simultaneously, the thumb and index finger of the dominant hand will be used to support the perineum, while the bent middle finger will grasp the baby's chin. Once a good grip is achieved, the investigator slowly assists in the expulsion of the fetal head from the vaginal introitus. When most of the fetal head is out, the perineal ring will be pushed under the baby's chin.

Women will not be given any instructions regarding straining and breathing, and will be allowed to follow their own pushing impulses. During the expulsion of the fetal head, the hands of the researcher will be kept in the air and ready for the intervention, but pressure will not be applied to the fetal head or perineum unless necessary (fetal hypoxic appearance, strain detection with a risk of spontaneous laceration towards the anus in the midline).
