      • 1.
        1. New techniques for in utero fetal studies have been used in the determination of the response of the fetal cardiovascular system to maternally administered Nembutal and epinephrine and maternal shock.
      • 2.
        2. Maternal infusion of Nembutal causes a significant deterioration in the fetal electrocardiogram prior to that of the mother.
      • 3.
        3. The fetus is sensitive to the direct injection of very small amounts of epinephrine.
      • 4.
        4. Administration of epinephrine to the pregnant animal decreases uterine artery blood flow and frequently lowers fetal arterial pressure.
      • 5.
        5. Epinephrine given directly to the fetus immediately after the injection of epinephrine into the mother often elevates fetal arterial pressure.
