Brief Summary

Atrial fibrillation (AF) occurs in 20% to 40% of patients after Coronary artery bypass grafting (CABG) and is associated with numerous detrimental sequelae. In postoperative period, the patient may be exposed to several proarrhythmogenic factors as increased endogenous catecholamines, inflammatory and oxidative mediators secondary to surgical stress and the systemic response to cardiopulmonary bypass, use of inotropic support. Steroids suppress the release of the above-mentioned inflammatory mediators. Dexmedetomidine is sympatholytic, along with anti-inflammatory properties. so combined use of both drugs may have synergistic effect to prevent post operative AF (POAF)

ACTIVE COMPARATOR

Patients will receive dexmedetomidine 0.7 ɥg/kg/hr IV infusion before aortic cross-clamping, and will be continued intra-operatively and in ICU till weaning from mechanical ventilation Patients also will also receive Hydrocortisone 100 mg intravenous (IV) before aortic cross-clamping then 100 mg every 8 hours after surgery which will be continued for 48 hours .

Drug: Dexmedetomidine + Hydrocortisone

Standard group

NO INTERVENTION

Patients will not receive dexmedetomidine nor Hydrocortisone and will receive the standard management
