目的:观察益龙血脉通胶囊对血液动力学的影响。方法:用多道生理记录仪和电磁流量计记录麻醉状态下猫的各项血液动力学指标。结果:益龙血脉通胶囊可使左心室压力、左心室压力最大变化速率、心输出量、心脏指数、脑血流量等明显增加,对平均动脉压、外周血管阻力没有明显影响。结论:益龙血脉通胶囊可使心脏收缩力和心脏泵血功能增强,从而使心输出量增加;它对外周血管的扩张作用较弱,但可使脑血管阻力下降,脑血流量明显增加。
Objective: To observe the effect of Yilong Xuemaitong capsule on hemodynamics. Methods: The hemodynamic parameters of cats under anesthesia were recorded with multi-channel physiological recorder and electromagnetic flowmeter. Results: Yilong Xuemaitong capsule can increase left ventricular pressure, maximum change rate of left ventricular pressure, cardiac output, heart index, cerebral blood flow, etc., and has no significant effect on mean arterial pressure and peripheral vascular resistance. Conclusion: Yilong Xuemaitong capsule can increase the cardiac contractility and pumping blood function of the heart, so that the cardiac output increases; it has a weaker expansion effect on the peripheral blood vessels, but it can make the cerebral vascular resistance drop and the cerebral blood flow increase obviously.
