Doppler Echocardiographic Studies of Deteriorating Growth-Restricted Fetuses.

Examination of the fetal circulation by Doppler techniques provides evidence of some of the mechanisms of adaptation and decompensation of the IUGR fetus in response to uteroplacental insufficiency. At present, the condition of IUGR fetuses can be accurately assessed by sequential studies of Doppler waveforms from various vascular areas. Therefore the optimal timing of delivery to prevent intrauterine injury may be guided by combining multivessel Doppler ultrasounds. Combining Doppler, composite biophysical profile, and/or computerized fetal heart rate analysis will provide significant early indication for action in the management of severe IUGR fetuses.
