Abstract:
:Chronic intrauterine hypoxia was induced in third-trimester lamb fetuses by daily embolization of the maternal side of the placenta with nonradioactive microspheres. After delivery at term, the chronically hypoxic fetuses had significantly increased pulmonary artery pressures when compared to nonhypoxic control measurements. This preparation appears to be a satisfactory model for experimental study of persistent pulmonary hypertension in the neonate.
