- 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.
