A1 NELSON, KARIN B. YR 1989 UL http://pediatrics.aappublications.org/content/83/4/654.abstract AB Dr Hermansen makes several points that do not contradict our paper and then he makes a leap in logic that does. We agree with him that there is some correlation, although a weak one, between pH and one-minute Apgar scores and that there is not much evidence that pH predicts long-term neurologic dysfunction. In fact, Dijxhoorn and co-workers found that pH does not explain most neurologic dysfunction even within the neonatal period. Ruth and Raivio, in the first birth cohort study of the predictive value of pH and other measures of neonatal acid-base balance, reported that none of these measures was better than, or even as good as, the Apgar score in predicting neurologic status at 1 year.
