Utero-placental blood velocity resistance index and umbilical venous pO2, pCO2, pH, lactate and erythroblast count in growth-retarded fetuses.
In 32 pregnancies complicated by intra-uterine growth retardation, umbilical venous blood was sampled by cordocentesis and the utero-placental blood velocity resistance index (RI) was recorded using Doppler ultrasound. Significant correlations were found between the utero-placental RI and fetal hypoxia, hypercapnea, acidosis, hyperlactaemia and erythroblastosis.
