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.

Describe the importance of monitoring dead space during thoracic surgery, specifically during one-lung ventilation. ⋯ Monitoring dead space helps anesthesiologists monitor the status of the lung and find appropriate ventilatory settings during thoracic surgeries.

ReviewTransesophageal echocardiography in thoracic anesthesia: pulmonary hypertension and right ventricular function.
Pulmonary hypertension is associated with increased postoperative morbidity and mortality. Early diagnosis and echocardiographic detection of right ventricular (RV) dysfunction are paramount in perioperative management. The goal of this review is to provide an overview of the recent literature on this topic. ⋯ More pulmonary hypertension patients are presenting for noncardiac surgery, creating a challenge for the anesthesiologist. Echocardiographic detection of RV dysfunction can be difficult. Routine use of intraoperative transesophageal echocardiography in major thoracic surgery is not advocated yet, but the development of automated techniques may provide an objective assessment of RV function.

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.

The mean age of patients presenting for thoracic surgery is rising steadily, associated with an increased demand for thoracic surgical treatments by geriatric patients. With increasing age, physiologic changes and comorbidities have to be considered. Thoracic anesthesia for elderly patients requires greater specific knowledge. ⋯ Considering key points of physiology and pharmacology can help to provide best possible care for the increasing number of elderly patients in thoracic surgery. Management of geriatric patients in thoracic surgery offer opportunities for anaesthetic interventions including protective ventilation, use of different anesthetics, anaesthesia monitoring, fluid management and pain therapy.
