Ethical aspects, safety issues of cardiac surgery and prediction of adverse events

In cardiac surgery, patient’s awareness and consent to surgery are problematic as due to the lack of previous medical background a patient can’t understand the processes occurring in the body and effects of exposure on them. Thus, provision of sufficient information by a doctor is a part of safe surgical strategy. An open randomized prospective trial involving 89 patients with stable coronary artery disease (CAD) was conducted. High rate of blood oxidation is believed to be an independent predictor of cognitive dysfunction development during the early postoperative period of coronary artery bypass grafting (CABG). Determination of blood oxidation rate is a tool of risk management during cardiac surgery starting from the stage of preoperative preparation, which is optimal to implement a safe strategy, including psychological and drug-induced support of the patient aimed at prevention of cognitive disturbances.
