Value of the knowledge of the mechanical-traumatic component in the course of delivery under the aspect of electronic birth monitoring.

Three cases were detailed pointed out. They demonstrate the opinion of the author about the relations between mechanical cerebral pressure on the fetus, fetal CTG, fetal pH and neurological findings during neonatal period. It is possible, that a cerebral damadge resulting from mechanical birth trauma occours without the findings of variable decelerations and Dip II in the fetal CTG or without fetal acidosis. Our conclusions are: terminate the delivery after 2 hours severe Dip I under normal fetal pH or after 12 hours of efficient labour.
