ABSTRACT
INTRODUCTION Cesarean delivery (CD) in many cases contributes to a higher survival and better outcome for the newborn. In acute conditions it may prevent or limit perinatal adverse effects and reduce the risk of hypoxic ischemic encephalopathy (HIE). It seems, therefore, that a ratio that is too low is associated with an increased neonatal risk. On the other hand, a CD ratio above a certain level probably does not further reduce neonatal morbidity and mortality.
