Behavioral states in the fetus near term.
On the basis of comparison and analogy it can be stated. that in the mature fetus behavioral states comparable to those seen in the newborn infant, i.e. quiet sleep, active sleep and even some kind of wakefulness do exist (1). These states can be identified fairly well from heart rate and motor activity patterns. According to evaluation of 8 hour recordinqs of FHR and fetal movements in the fet...
متن کاملUmbilical vein blood volume flow rate and umbilical artery pulsatility as 'venous-arterial index' in the prediction of neonatal compromise.
OBJECTIVE To assess the diagnostic power of the umbilical venous-arterial index (VAI) for the prediction of poor fetal outcome. SUBJECTS AND METHODS This was a retrospective, cross-sectional clinical study in which normalized umbilical vein blood volume flow rate (nUV) (mL/min/kg estimated body weight), umbilical artery pulsatility index (UAPI), the newly developed VAI (nUV/UAPI), and the ute...
متن کاملBehavioral states and breathing activity in the fetus near term.
Measurement of fetal breathing movements (FBM) has found considerable clinical interest recently, because it is thought to be predictive of fetal health or compromise. However, from our investigations on fetal state behavior [7, 8] methods for assessing FBM generally used so far seem to be inadequate and results are suspect of being unreliable: in the fetal lamb and in the rhesus monkey fetus F...
متن کاملVenous flow velocity, venous volume and arterial blood flow.
The relationship of arterial blood flow and venous volume to venous flow velocity was studied in normal subjects. The effects of current modes of treatment in venous thrombosis and of a vasodilator drug on venous flow velocity were also investigated. Total calf flow and venous volume were measured by venous occlusion plethysmography while venous flow axial velocity was determined by the transit...
متن کاملFetal Doppler: umbilical artery, middle cerebral artery, and venous system.
One of the most important applications of Doppler ultrasonography in obstetrics is the detection of fetal anemia in pregnancies complicated by either red-cell alloimmunization or by other causes of fetal anemia. Doppler of the umbilical artery also has prognostic value in pregnancies affected by twin-twin transfusion syndrome undergoing in-utero intervention. Another potential major application...
