To examine brain blood flow and oxygen delivery to 14 brain regions in fetal guinea pigs near term, six fetuses were catheterized under general anesthesia of the dam on days 61–63 of pregnancy. In the control period, fetal arterial blood pressure was measured and a blood sample was taken from the right axillary artery to determine fetal blood gases and acid base balance. Isotope-labeled microspheres were then injected in a lateral saphenous vein, and a reference blood sample was taken from the axillary artery according to Carter and Gu (1988).
