Objective: To investigate the effect of Xingtong Oral Solution on cardiac hemodynamics and myocardial oxygen consumption in dogs.Methods: The coronary blood flow and cardiac outpout were measured by electromagnetic flowmeter. The internal pressure of left ventricle was determined by carrier amplifier. And the blood oxygen content was also determined by oximeter. Results: Xintong Oral Solution can raise the internal pressure of left ventricle, enhance the work of left ventricle and reduce the peripheral resistance. Conclusion: Xintong Oral Solution can obviously reduce myocardial oxygen consumption and coronary resistance. It is also to give protection to myocardial ischemia.

The paper expounds the scientific management of the science of emergency treatment in the following aspects, organization and structure, quality, computerized information, and special emergency treatment combined with general emergency treatment. It also discusses the management of services facilitating emergency treatment, such as administration, goods provision, human resources, economy, and contingency plans for emergent events.
