ReviewFluid management in the cardiothoracic intensive care unit: diuresis - diuretics and hemofiltration.
The present review discusses the current concepts of fluid management in cardiothoracic surgery, and its clinical implications with special reference to organ-related complications and their prevention. ⋯ The optimal fluid management in cardiothoracic patients has not been settled. Results of recent clinical published trials highlight the need for minimizing fluid administration and attempting to use diuretics to achieve a negative fluid, although hypovolemia and hypoperfusion should be carefully considered. An individualized optimization of fluid status, using goal-directed therapy, has emerged as a possible preferable approach. The old debate between crystalloid and colloid solutions has been partially solved, as some colloids have demonstrated deleterious effect on renal function and coagulation system. Various preventive strategies have also emerged for minimizing fluid-related complications.

ReviewInflammatory response to trauma: implications for coagulation and resuscitation.
Recent studies have changed our understanding of the timing and interactions of the inflammatory processes and coagulation cascade following severe trauma. This review highlights this information and correlates its impact on the current clinical approach for fluid resuscitation and treatment of coagulopathy for trauma patients. ⋯ Traumatic injuries continue to be a significant cause of mortality worldwide. Recent advances in understanding the mechanisms of end-organ failure, and modulation of the inflammatory response has important clinical implications regarding fluid resuscitation and treatment of coagulopathy.

ReviewThe changing anesthesia economic landscape: emergence of large multispecialty practices and Accountable Care Organizations.
In this review, we evaluate the current US employment models for healthcare in general and anesthesiologists in particular and the emergence of large, multispecialty physician groups and the forces behind this change to the current anesthesia practice model. We will also examine the present payment method for anesthesiologists and determine how Accountable Care Organizations will affect the future payment models. ⋯ This is the most critical time in the specialty of anesthesiology from an economic viewpoint, and significant threats and opportunities will arise for anesthesiologists in how they are reimbursed, and how they demonstrate the delivery of quality care to patients.

Advances in medical care have led to an increasing elderly population. Elderly individuals should be able to participate in society as long as possible. However, with an increasing age their adaptive capacity gradually decreases, specially before and after major life events (like hospitalization and surgery) making them vulnerable to reduced functioning and societal participation. Therapeutic exercise before and after surgery might augment the postoperative outcomes by improving functional status and reducing the complication and mortality rate. ⋯ The perioperative exercise training protocol known under the name 'Better in, Better out' could be implemented in clinical care for the vulnerable group of patients scheduled for major elective surgery who are at risk for prolonged hospitalization, complications and/or death. Future research should aim to include this at-risk group, evaluate perioperative high-intensity exercise interventions and conduct adequately powered trials.

ReviewPreventing and managing perioperative pulmonary complications following cardiac surgery.
To provide an update of research findings on the mechanisms underlying respiratory complications after cardiac surgery, especially acute respiratory distress syndrome, transfusion-related lung injury and ventilation-associated pneumonia. The article will review some of the preventive and therapeutic measures that can be implemented to reduce these complications, focusing on the use of protective invasive ventilation and postextubation noninvasive ventilation. ⋯ Postoperative pulmonary complications are common, but severe complications are infrequent. Their reduction requires measures to prevent infection and mechanical ventilation-associated lung injury through the use of low tidal volumes and early extubation. Noninvasive ventilation after extubation can be utilized to avoid reintubation and the associated increased morbidity and mortality. However, noninvasive ventilation should be done under rigorous conditions and by following strict criteria.
