Dexmedetomidine and Myocardial Protection (DEXCARD)
Cardioprotective Effect of Dexmedetomidine in Patients Undergoing Cardiac Surgery With Cardiopulmonary Bypass: a Randomized, Placebo-controlled Trial
Dexmedetomidine, an alpha-2 agonist, is a sedative that is widely used in various clinical settings because, compared to benzodiazepines, it preserves respiratory function better and its duration of action is short.
Recent experimental studies showed a possibility that dexmedetomidine may have an organoprotective effect from ischemic-reperfusion injury by reducing inflammatory response. Besides, dexmedetomidine is known to be related with attenuated sympathetic tone and improved microcirculation.
Taken together, it is plausible that dexmedetomidine exerts cardioprotection in patients undergoing cardiac surgery with cardiopulmonary bypass and aortic cross-clamp.
The aim of this trial is to test the effect of dexmedetomidine on postoperative cardiac troponin I measurements in patients undergoing cardiac surgery.

Placebo Comparator: Control
Placebo group using normal saline infusion
|
During the same time window for dexmedetomidine, normal saline is infused at the same rate calculated for dexmedetomidine.
|
Active Comparator: Dexmedetomidine
From anesthesia induction before the initiation of cardiopulmonary bypass, dexmedetomidine is infused intravenously at a rate of 0.5 mcg/kg/hr after a loading dose infusion of 0.75 mcg/kg for 10 mins.
|
Anesthesia is induced using midazolam or etomidate, and sufentanil. A target-controlled infusion of propofol and remifentanil is used for anesthesia maintenance. From anesthesia induction before the initiation of cardiopulmonary bypass, dexmedetomidine is infused intravenously at a rate of 0.5 mcg/kg/hr after a loading dose infusion of 0.75 mcg/kg for 10 mins.
