back Evolution and prognosis
Perinatal asphyxia is associated with increased neonatal mortality influenced by gestational age. Long-term prognosis depends on the severity and duration of hypoxia and precocity initiation of resuscitation maneuvers. About 25% of these newborns die within the first hours or days after birth. Among survivors, even those who have seizures may have a favorable evolution further. Survivors that asphyxia was prolonged and severe neurological sequelae may, at a rate of 25-45% in term newborn and more to the premature infant. Neurological sequelae may include: cerebral palsy 5-10% (diplegie, spastic quadriplegia), severe mental retardation, blindness, impaired hearing, recurrent seizures, minor sequelae (social and school adjustment problems, disorders of speech), changes that may occur for a period of 2-3 years. It was found that perinatal factors in relation to asphyxia have a greater influence over the motor sequelae of cognitive and psychosocial and environmental factii about asphyxia have greater influence on cognitive sequelae. Major changes in cognitive function occur between 18-24 months of life, emphasizing the need for long-term follow-up infants with perinatal asphyxia.
