Acute kidney injury (AKI) is a long-recognized complication of cardiac surgery. It is a commonly encountered clinical syndrome that, in its most severe form, increases the odds of operative mortality three to eight-fold. The pathogenesis of cardiac surgery-associated acute kidney injury (CSA-AKI) is complex. No single intervention is likely to provide a panacea, and thus, the purpose of this review is to assess the wide breadth of emerging research into potential strategies to prevent, diagnose, and treat CSA-AKI. ⋯ Although there has been much high-quality research conducted in this field in recent years, preventing CSA-AKI by avoiding renal insults remains the mainstay of management. Although biomarkers have the potential to diagnose CSA-AKI at an earlier stage, efficacious interventions to treat established CSA-AKI remain elusive.

ReviewDiastolic dysfunction, diagnostic and perioperative management in cardiac surgery.
The review focuses on recent findings on the role of diastolic dysfunction in the perioperative period and on recent advances in the diagnosis and perioperative management of diastolic function. ⋯ Appropriate perioperative patient care requires that the perioperative physician be alerted to the presence of diastolic dysfunction, be knowledgeable of the diastolic dysfunction grading system and understand the pathophysiologic changes associated with various grades of diastolic function.

ReviewPreventive and therapeutic noninvasive ventilation in cardiovascular surgery.
Postoperative pulmonary complications are common after cardiac and vascular surgery, and they are associated with a marked worsening in hospital survival and length of stay. Noninvasive ventilation (NIV) has been successfully applied in the prevention and treatment of postoperative acute respiratory failure (ARF), including the cardiovascular setting. ⋯ NIV seems effective when applied to treat postoperative ARF. Its role as a preventive tool is still controversial, and probably should be limited to high-risk patients. Promising findings were reported for NIV application in pediatric patients and in ancillary procedures. So far, a cautious approach should be applied, as NIV failure is associated with poor outcomes if not quickly detected.
