Objective: To investigating the relationship between cord blood erythropoietin and clinical markers of fetal hypoxia. Methods: Erythropoietin (EPO) concentrations in umbilical venous blood were measured from 80 neonates with low-risk and different risk factors by radioimmunoassay (RIA). The relation between EPO concentration and clinical markers of fetal asphyxia was evaluated. Results: Median ...

The propagation of blood flow along the fetoplacental arterial system has been hypothesized to have a compensatory response to placental anomalies that may result in fetal stress. When the placenta generates increased resistance, the umbilical artery blood flow would decrease and in the worst scenario become absent, which will lead to fetal asphyxia and hypoxia. To compensate for the decreased ...

OBJECTIVES To address the clinical significance of sinusoidal heart rate (SHR) pattern and review its occurrence, define its characteristics, and explain its physiopathology. BACKGROUND In 1972, Manseau et al. and Kubli et al. described an undulating wave form alternating with a flat or smooth baseline fetal heart rate (FHR) in severely affected, Rh-sensitized and dying fetuses. This FHR patt...
