Objective: Characteristic changes in ductus venosus (DV) blood velocity and pulsations in the umbilical vein (UV) have been described during imminent fetal asphyxia. The aim of this study was to examine fetal venous blood velocity in relationship to

Urine production and weight deviation in a growth-retarded fetus with oligohydramnios was estimated by ultrasound on four occasions between weeks 27 and 33 of gestational age. The fetus demonstrated facial features typical of Potter's syndrome. Altho

In a chronically instrumented fetal lamb the effect on heart rate variability of noradrenaline as well as hypoxemia is studied by the use of power spectral analysis. Subsequent to both noradrenaline infusion and hypoxemia the very low frequency compo

Progressive changes in the S-T interval of the fetal ECG were studied in 22 lamb fetuses, acutely exteriorized and submitted to graded hypoxia. The ECG changes were studied in order to correlate them with cardiovascular function, as measured by heart

Electrocardiograms (ECG) were made immediately after delivery in 28 infants with normal cardiotocographic patterns in labour and in 29 with abnormal patterns. Changes in the S-T segment and T-wave were quantified in a scoring system. High and peaked

Beat-to-beat variability has been suggested as a sensitive indication of fetal well-being. The suggestion originates from case reports of observed decrease in variability preceding clinical signs of fetal asphyxia and fetal death. Against this backgr

During the years 1973-81, the cesarean section (CS) birth rate increased from 5.5% to 12.4% in Sweden. During the same time, perinatal mortality declined from 12 to 7.1 per thousand children. The rates of CS and perinatal mortality, however, cannot b

Progressive changes in the S-T interval of the fetal electrocardiogram (FECG) were studied in 14 lamb fetuses, acutely exteriorized and subjected to graded hypoxia. The aims of the study were to investigate whether beta-adrenoceptor stimulation and h
