Abstract

PURPOSE: Prediction of developmental outcome after perinatal asphyxia is important but difficult. The objective was to evaluate the relationship of perinatal risk factors and neonatal complications with Bayley Scales of Infant Development II (BSID-II) scores in asphyxiated newborns.
METHODS
Forty asphyxiated infants, admitted between January and December 1997, were studied at a mean corrected age of 12.7 months. Perinatal risk factors, neonatal complications and developmental outcome were evaluated. Subjects were classified by BSID-II scores: 23 infants with normal development [Mental Developmental Index(MDI) and Psychomotor Developmental Index(PDI) > or =85] in Group 1, and 17 with delayed outcome(MDI or PDI<85) in Group 2 [Group2A: 10 infants with mild delay(MDI and PDI > or =70), and Group2B 7 with significant delay(MDI or PDI < or =70)].
RESULTS
MDI and PDI in Groups 1 and 2 were 98.97.0 and 108.4+/-10.1 vs. 79.3+/-16.2 and 79.5+/-22.6, respectively. MDI and PDI of Groups 2A and 2B were 85.7+/-11.4 and 94.215.7 vs.8.4 and 58.6+/-11.0, respectively. There were no significant differences in Apgar score, fetal deceleration, seizure, meconium aspiration, pH, BE, pCO2, LDH, CPK, CPK isoenzymes, EE(and brain ultrasonographic findings between Groups 1 and 2. But ultrasonographic findings were significantly different between Groups 1 and 2B.
CONCLUSION
There was no significant difference of perinatal risk factors or neonatal complications between normal and delayed developmental groups by Bayley scales in asphyxiated newborns.
