Effect of maternal hyperoxygenation on experimentally produced uteroplacental insufficiency in the rat.
The paper examines the effects of maternal hyperoxygenation on uteroplacental insufficiency produced by ligation of the uterine artery. Maternal hyperoxygenation did not significantly affect experimentally produced growth retardation or survival of the fetuses from the ligated horn. Analysis of the vascular anatomy revealed that additional oxygen improves the survival of fetuses compromised by uteroplacental insufficiency only in the presence of anastomosis between the uterine and ovarian arteries. The study demonstrated the importance of that anastomosis in evaluating the results obtained by this experimental model.
