Umbilical artery Doppler flow velocity waveform studies were performed over a period of 4 y on 242 women with severe pre-eclampsia before 34 wk gestation. Sixty-eight (28%) had absent end-diastolic umbilical artery Doppler flow velocities. One hundred and ninety-three infants survived to hospital discharge and were followed at 6-monthly intervals until 48 mo of age. The mean corrected developmental quotient was 94 +/- 8 at 24 mo of age and 87 +/- 9 at 48 mo. Ninety-two percent of the infants had a developmental quotient of >80 at 24 mo and 72% at 48 mo of age. This decline is thought to be due to the impact of social circumstances. There were no differences between the developmental quotients of the infants with normal and those with absent end-diastolic umbilical artery Doppler flow velocities at either 24 or 48 mo of age. At 24 mo of age, infants with absent end-diastolic umbilical artery Doppler flow velocities scored lower in the Performance subscale test (p = 0.03). The developmental quotients of infants from poorer socioeconomic backgrounds were significantly lower than those living in more privileged circumstances. At 48 mo, 153 (97%) of the children presented with normal gross motor development. Four infants had cerebral palsy. No differences were noted in the motor outcomes between the infants of women with normal umbilical artery waveforms and those with absent end-diastolic umbilical artery Doppler flow velocities.
