简要总结
Fetal heart rate abnormalities are common. Miller et al. have demonstrated that new onset fetal heart rate abnormalities after initial labor epidural dosing occur more frequently in women with a low admission pulse pressure than those with a normal admission pulse. The aim of the present study is to look for a statistical link between the occurrence of a fetal heart abnormality requiring an intervention and maternal hemodynamic factors (blood pressure, pulse pressure, and cardiac output) measured before epidural analgesia in two positions: dorsal decubitus position and in the left lateral decubitus.
