The fetus requires large amounts of volume when weaning from cardiac bypass. This suggests that placental vasculature can act as a large capacitor in the fetal circulation. To assess placental compliance of fetal lambs, seven isolated in situ lamb placentas were placed on extracorporeal circulation. Umbilical artery blood flow was varied from 0 to 350 ml. min(-1). kg fetal wt(-1). Because the extracorporeal circuit is a closed system, volume changes in the placenta induced by umbilical artery…

Cardiac output and blood flow volume redistribution during acute maternal hypoxia in fetal sheep

Investigation of cardiac output (CO) and blood flow redistribution following induction of acute hypoxia in a fetal sheep model significantly increases the proportion of the placental blood passing through the DV and reduces the placential fraction of CO and the R/L heart ratio.

The increased systemic resistance induced by vasoconstrictors may increase the circuit blood flow excessively, resulting in circulation failure in systemic organs; therefore, vasodilators may be more useful than vasoconStrictors for maintaining organ blood flow within this circuit.

The clinical implication is that decreased placental flow and pressure on CPB may lead to a vicious cycle, resulting in further impairment of placental perfusion and respiratory gas exchange, and hypothermia promotes this impairment.

The Circulation of the Fetus in Utero: Methods For Studying Distribution of Blood Flow, Cardiac Output And Organ Blood Flow

Experimental evidence is provided that (1) there is no significant recirculation of microspheres, (2) the distribution of spheres is proportional to flow, and (3) circulatory physiology is not altered by injection of spheres.

Determination of Fetal, Placental and Neonatal Blood Volumes in the Sheep

A sheep preparation was developed for studying fetoplacental and neonatal blood volumes using isotope dilution techniques, and placental blood volume was independent of fetal weight and remained relatively constant during the last fourth of gestation.

Fetal placental vascular responses to prostacyclin after angiotensin II-induced vasoconstriction.

It is concluded that angiotensin II causes fetal hypertension and renal and intestinal vasoconstriction, which are reversed by prostacyclin.
