Intrapartum fetal hypoxia: a study of long-term morbidity

Reported is the second phase of a prospective follow-up study of 37 children who had episodes of intrapartum fetal hypoxia at delivery identified by an acid-base assessment and of a control group of 59 children who had no evidence of intrapartum fetal hypoxia. The newborn infants were normally grown and mature at delivery. Follow-up assessments of motor, cognitive, and language development were made between 1 and 6 years of age. There was no significant difference in the pattern of physical growth and the incidences of motor and cognitive handicap or developmental delay, language developmental delay, and tests of vision and hearing in the children of the hypoxia group and the children of the control group. These findings suggest that acid-base measures of metabolic acidosis can be used as a method of assessment of the mature normally grown fetus during labor without compromising the long-term outcome of the child.
