Decreasing Preoperative Stress to Prevent Postoperative Delirium and Postoperative Cognitive Decline in Cardiac Surgical Patients.

Patients undergoing cardiac surgery often complain of anxiety before a major operation and the resulting stress. This circumstance is a risk factor for mental problems that may occur after the operation (e.g., delirium or memory deficits). This study aims to prevent these discomforts by a preoperative relaxation intervention.
