Insufficient attention traditionally existing even in medical institutions that realize the principles of modern risk strategy impairs the perinatal outcomes. The birth outcomes in the newborns make up the main criterion for the implementation of accounting intrapartum risk factors. Since 2010 it is proved from a strong correlation between the growth of risk intrapartum and neonatal condition [EAGO, Lisbon, 2010; IN Kostin, 2012]. This study is undertaken in order to increase attention to the intrapartum risk factors, determining their contribution and force effects on birth outcomes. Objective: to determine the main injuries in fetus and newborn delivered by cesarean section in full cervical dilatation. We determined the threshold level of intranatal augmentation requiring changing labor management. The critical level of intranatal augmentation after abdominal delivery in full cervical dilatation is 82%. 41.7% of newborns with intranatal augmentation 82% and more need intensive care and resuscitation.
