Coronary Artery Bypass Grafting, Delirium Treatment, Dexmedetomidine, Pregabalin
Conditions
Brief summary
The aim of this study is to determine the effect of pregabalin versus dexmedetomidine on the treatment and lasting duration of delirium in fast tracking elderly patients after Coronary Artery Bypass Grafting.
Detailed description
Delirium is an acute brain disorder that involves changes in consciousness, attention, cognition, and perception.The incidence of postoperative delirium (POD) is high among patients undergoing cardiac surgery, ranging from 20 to 50%, and the risk is even higher in the elderly.
Interventions
DRUGPregabalin
Patients will receive pregabalin capsules (75 mg) every 12 h for 24 hours by nasogastric tube.
