Intrapartum fetal asphyxia: a preliminary report in regard to long-term morbidity.

This is a preliminary report of a prospective follow-up study of 42 infants who had episodes of intrapartum fetal asphyxia at delivery identified by an acid-base assessment and a control group of 69 babies who had no evidence of intrapartum fetal asphyxia. The newborn infants were mature at delivery. There were no major neurologic disabilities in the asphyxia group. The pattern of physical growth and the mental and physical development indices of the babies of the asphyxia group were similar to those of the control group babies at 12 months of age. Results have not as yet indicated that the mature fetus with at least a terminal episode of asphyxia will exhibit evidence of handicap due to central nervous system injury.
