Summary

About 200000 cardiac operations are performed in China every year. Cardiopulmonary bypass is the basic strategy of open-heart surgery, which may lead to myocardial ischemia-reperfusion injury and low cardiac output syndrome. It will inevitably affect the patient's postoperative recovery. A number of studies have shown that dexmedetomidine, as an auxiliary sedative, has the effects of inhibiting stress response, antiarrhythmia and cardiac protection.Dexmedetomidine has been widely used in anesthesia in cardiac surgery. However, at present, few clinical studies pay attention to its mechanism. In this study, dexmedetomidine will be used in cardiac surgery with cardiopulmonary bypass to explore the mechanism of cardiac ischemia-reperfusion injury and the protective effect of dexmedetomidine.

Conditions

  • Ischemia-Reperfusion Injury

Interventions

DRUG

dexmedetomidine

The participant will pump dexmedetomidine at the rate of 1μg/(Kg·h) for 10 minutes at the beginning of anesthesia induction, and then maintain the pump at a rate of 0.5μg/(Kg·h) during the operation.

DRUG

Placebo

The participant will pump saline without dexmedetomidine at the same speed as group D.
