Intrapartum asphyxia and cerebral palsy.

Freeman and Nelson recently presented a review of the relationship between fetal distress and subsequent cerebral palsy. Their review supported the theory that most cases of cerebral palsy are not caused by birth asphyxia. However, the review and its conclusions must be interpreted cautiously because the authors omitted important data that contradict their theory. At least five studies have presented data comparing pH at birth and Apgar scores (Table). In all five studies, some infants with acidemia had a one-minute Apgar score of 7 or more.
