Large amounts of experiments have proved that sevoflurane,both preconditioning and post-conditioning,has the cardio-protective effect. However,the specific mechanism of this effect has been studied a lot and is greatly disputed. This article reviews these mechanisms in the cardio-protective effect of sevoflurane. Meanwhile,theoretical bases for rational administration of sevoflurane during clinical anesthesia are provided. The application and its limitations of the cardio-protective effect of sevoflurane in the current clinical work,along with our expectations are also put forward.
