Blood Flow and Behavioral States in the Human Fetus

Résumé fourni par la source

In the human fetus, behavioral states were studied from fetal heart rate (FHR) recordings alone and in conjunction with body movements, resulting in the description of quiet and activity phases. The observations did not provide conclusive proof of the presence of true behavioral states in the human fetus, since both FHR and FHR variability are affected by fetal motility. This chapter reviews the latest reports on the relationship between the blood flow velocity waveform in the lower thoracic part of the fetal descending aorta, fetal internal carotid, and umbilical artery and fetal behavioral states, in particular, stage IF and 2F in the normal growing and growth-retarded human fetus at term. It discusses the relationship between separate state variables and the blood flow velocity waveform in the lower thoracic part of the fetal descending aorta in the human fetus at 27 to 28 weeks of gestation.
