Delirium, which generally is triggered by underlying medical conditions, is an acute and fluctuating disorder associated with attention and cognitive defects, and frequently accompanied by excessive arousal and perception-related problems. Delirium may lead to a variety of complications, e.g. cognitive impairments. Development of delirium is promoted by both anaesthesia and pain. Patients subjected to cardiac surgeries are at risk of delirium due to such factors as extracorporeal circulation applied during the intervention and various cardiovascular complications. Rapid identification of the problem may help eliminate avoidable complications which can be prevented at an early stage.
