Long-term prognosis of asphyxiated full-term neonates with CNS complications
Insights
Neonatal asphyxia can lead to serious complications like hypoxic-ischemic encephalopathy. Early detection of risk factors, such as absent Moro reflex, is crucial for predicting long-term outcomes in affected infants.
Area of Science:
- Neonatal neurology
- Perinatal medicine
- Pediatric neurology
Background:
- Perinatal asphyxia is a significant cause of neonatal mortality and long-term neurological disability.
- Hypoxic-ischemic encephalopathy (HIE) is a major complication in asphyxiated neonates.
Purpose of the Study:
- To evaluate the long-term neurological outcomes of asphyxiated neonates with central nervous system (CNS) complications.
- To identify predictive risk factors for sequelae in these infants.
Main Methods:
- Retrospective study of 86 asphyxiated full-term neonates admitted between 1972-1981.
- Follow-up of survivors for 3 to 13 years to assess neurological abnormalities.
- Statistical analysis to identify predictive risk factors.
Main Results:
- 73% of neonates survived the neonatal period; 24% of survivors developed major or minor abnormalities.
- Major abnormalities included cerebral palsy, epilepsy, and mental retardation.
- Absence of Moro reflex and abnormal neurological signs at discharge were significant predictors of sequelae.
Conclusions:
- A significant proportion of asphyxiated neonates develop long-term neurological handicaps.
- Early identification of risk factors is vital for timely intervention.
- Improved preventive and intensive care for perinatal asphyxia is essential to reduce childhood disability.
Abstract:
Eighty-six asphyxiated full-term neonates with CNS complications such as hypoxic-ischemic encephalopathy, admitted during a 10-year period (1972-81), were studied. Sixty-three (73%) of the infants survived the neonatal period, and 55 of these, excluding one who died at 7 months, were followed for 3 to 13 years. Thirteen (24%) of these 55 children showed either major (n = 8) or minor (n = 5) abnormalities. The former had multiple significant handicaps such as cerebral palsy, epilepsy and mental retardation. The latter had mild sequelae that did not interfere with normal life. High risk factors of predictive value in infancy for the sequelae were the absence of the Moro reflex over 6 days and abnormal neurological signs on discharge (P less than 0.001, respectively). Although the neonatal mortality decreased slightly in the last four years (1978-81) compared to in the first and second three year periods (1972-74, 1975-77) (P less than 0.10), the unchanged pattern of the outcome over the 10 years might indicate the importance of more preventive and intensive care for perinatal asphyxia to reduce the incidence of handicapped children.
