Observational StudyDisturbances in Oxygen Balance During Cardiopulmonary Bypass: A Risk Factor for Postoperative Delirium.
The aim of this study was to determine risk factors for postoperative delirium after cardiac surgery, specifically associated with the conduct of cardiopulmonary bypass (CPB). ⋯ The influence of the SvO2 level during CPB, fluid balance, and patient age should be recognized as risk factors for postoperative delirium after cardiac surgery in patients 70 years and older.

Review Meta AnalysisEffects of Positive Airway Pressure and Mechanical Ventilation of the Lungs During Cardiopulmonary Bypass on Pulmonary Adverse Events After Cardiac Surgery: A Systematic Review and Meta-Analysis.
To investigate whether different ventilation strategies during cardiopulmonary bypass (CPB) can improve outcomes in adult cardiac surgery patients. ⋯ CPAP during CPB improved the alveolar-arterial oxygen gradient difference compared with apnea, but ventilation during CPB did not. Neither CPAP nor ventilation during CPB demonstrated evidence of improving clinical outcomes in low- or intermediate-risk patients for elective cardiac surgery. The findings are inconclusive because of heterogeneity and small sample sizes.
