✦ Synopsis

perature deflection of the aortic probe was recorded and cardiac output was calculated. Three control CO were determined. After giving the challenge dose, CO was measured at 3, 5, 10, i5, 25, 35, 45, and 60 min. All 6 animals showed a significant (P < .01) fall in CO, cardiac index (CI), and blood pressure (BP) within 3 rain after administering the challenge dose. The fall in cardiac index was 50% or greater in all animals. No animals died as a result of shock. All animals showed spontaneous recovery to baseline values of CO, CI, and BP by 60 min. By avoiding anesthesia, which can depress the cardiovascular system, the baseline values of CO, CI, and BP are essentially unchanged from unanesthetized rabbits. This model is reproducible and relatively inexpensive, yet affords good hemodynamic parameters with which one can evaluate new treatment procedures.
