Red cell surface architectonics and ultrastructure were studied in pregnant women, their fetuses, and newborns in normal and complicated pregnancy. The results were correlated to dopplerometric blood stream parameters of uterine artery and fetal umbilical artery. The most grave changes in red cell structure were detected in women with medium-severe and grave OPH gestosis: the share of red cell discoid forms was reduced by 21%, that of nontransitional forms ("shrunk ball"-shaped cells, spherocytes, degeneratively changed cells) increased by 17%. Deterioration of blood rheology in complicated pregnancy correlated with reduced fetoplacental and uteroplacental blood stream and with unfavorable perinatal outcomes.
