Page Contents Physiology: Birth Transition from Fetal Circulation Alveolar fluid is replaced with air on initial ventilations Critical first step that leads to reduced pulmonary vascular resistance Results in an increase in PaO2 with an associated decreased in pulmonary vascular resistance Negative intrathoracic pressure increases Initiated with uterine contractions and travel through the birth canal First few breaths add to the negative intrathoracic pressure Increased pulmonary perfusion Results from less resistance to flow through pulmonary system than through fetal shunts Increased systemic vascular resistance following delivery Flow reverses in the ductus arteriosus now traveling aorta to pulmonary artery Closure of shunts last steps in transition Ductus arteriosus closes within hours to days unless Patent Ductus Arteriosus Foramen ovale closes last Results from increased left atrial flow and pressure Myocardium changes Right ventricle wall thins Left ventricle wall hypertrophies.

Extracorporeal Perfusion of the Human Foetus, Placenta and Foeto-Placental Unit

The development and the reactivity of fetoplacental circulation appear to be extremely well coordinated phenomena which follow a precise chronology and are regulated by numerous angiogenic and vasoactive factors. The endothelium of the villous vessels, due to its capacity to release vasodilatating substances, would appear to play a crucial role in the gradual decrease in the vascular resistance of the placenta, thereby enabling it to meet the growing needs of the fetus right up until the end of pregnancy. In the endothelium, as in the smooth muscle of the placental vessels, control of production and mechanisms of action of the signal modulators of placental tone - endothelin 1, nitric oxide, prostanoids, etc. The study of their interactions could contribute to better evaluating the relative importance of each of them in the particular balances which are established at different stages of normal pregnancy, as well as during pathological situations pre-eclampsia, intrauterine growth retardation, etc. Schaaps, V.
