[Diagnosis of chronic fetal anoxia]

The intrauterine fetal status was assessed in women at 34-42 week gestation; the pregnancies were complicated by obstetric and extragenital disease (nephropathy, prolonged gestation, hypertension, diabetes mellitus, renal disease). Computer-assisted analysis of the diagnostic value of fetal cardiotocography, uterine-placental hemodynamics, and acid-base status of maternal capillary blood showed that the following parameters are most informative for the diagnosis of chronic fetal hypoxia: stable rhythm duration; oscillation amplitude; acceleration/deceleration number, amplitude, and duration; volume flow rate of the uterine-placental unit; and pH and base deficiency in the blood taken from the cervix uteri.
