The Influence of Cardiopulmonary Bypass on the Incidence of Postoperative Delirium in Cardiac Surgery

Background: The incidence of postoperative delirium (POD) following cardiac surgery is rising as a result of increased age and complexity of patients. The ensuing problems are not only costly, but are commonly associated with long-term morbidity and increased mortality. We conducted a case–control study to assess the contribution of cardiopulmonary bypass (CPB) to the development of POD.
