In Reply.—We appreciate the comments of Dr Todd and certainly agree with him that there is an inexact correlation between the one-minute Apgar score and the degree of perinatal asphyxia. However, since only three of the infants in our study had clinical evidence of severe asphyxia that required prolonged resuscitation, we were unable to analyze statistically the relationship between clinical asphyxia and CSF β-endorphinlike immunoreactivity. The only usable measurement we had with which we could do our correlation was the one-minute Apgar score.
