Aim:
To identify early predictors of outcome in infants born at 25 gestational weeks.
Material And Methods:
Data from a regional perinatal database (time-period 1995-2001, total n = 108 000 births) were used. Apgar scores were available in 92 preterm infants, born at 25 + 0 to 25 + 6 gestational weeks, and analyzed in relation to short-term outcome (180-day survival with, or without, severe brain damage defined as intraventricular hemorrhage grade 3-4 or cystic periventricular leukomalacia). Based on multiple logistic regression analyses we constructed graphs of the estimated chance of survival.
Results:
Apgar scores at 1, 5 and 10 min correlated with survival without severe brain damage (p = 0.02, 0.006 and 0.006, respectively). Survival without severe brain damage was higher in singleton than in multiple births (p = 0.03); there was no association with infant gender or mode of delivery. The strongest model for prediction of survival without severe brain damage was based on 5-min Apgar score and the Clinical Risk Index for Babies (CRIB), (p < 0.001).
Conclusion:
Apgar score predicts short-term outcome in extremely preterm infants at 25 gestational weeks. The precision for prediction of outcome increases when Apgar score is combined with CRIB.
