氙气对心脏功能保护作用的研究进展

Xenon has been proven to be a potent inhalation anesthetic for nearly 60 yr. The properties of fast induction, early recovery, as well as the significant analgesic effect of xenon contribute to its ideal agent features. The hemodynamic advantage of xenon has been evidenced in animal and clinical studies. Moreover, xenon provides anesthesia without cardiac function compromise and is considered as appropriate anesthesia agent for cardiovascular surgery and patient with related risks. In addition, xenon provides protective effect on ischemia-reperfusion organ especially on the myocardium. The myocardial infarction size can be reduced after xenon application. This article summarized the effects of xenon on cardiac function and myocardium, and further discussed the mechanism.
