To examine the potential harmful effects of hyperoxia and summarize the results of most recent clinical studies evaluating oxygen therapy in critically ill patients. ⋯ Liberal O2 use and unnecessary hyperoxia may be detrimental in critically ill patients. The current evidence supports the use of a conservative strategy in O2 therapy to avoid patient exposure to unnecessary hyperoxemia.

ReviewRenal replacement therapy in critically ill patients: who, when, why, and how.
The increasing incidence of acute kidney injury has the immediate effect of a growing need for renal replacement therapy (RRT). Shedding light on the questions of who, when, why, and how RRT should be performed is difficult to accomplish because of ambiguous study results, poor quality evidence, and low standardization. ⋯ The best management of RRT is still a subject of controversy. Continuous RRT with regional citrate anticoagulation via a temporary catheter in a jugular vein is the recommended first choice treatment option in critically ill patients with acute kidney injury.

ReviewRole of the anesthesiologist-intensivist outside the ICU: opportunity to add value for the hospital or an unnecessary distraction?
Given the extremely expensive nature of critical care medicine, it seems logical that intensivists should play an active role in designing efficient systems of care. The true value of intensivists, however, is not well defined. ⋯ Anesthesiologist-intensivists working outside their usual environment provide leadership and clinical guidance towards improving patient outcomes.

Published data and practice recommendations on end-of-life (EOL) generally reflect Western practice frameworks. Understanding worldwide practices is important because improving economic conditions are promoting rapid expansion of intensive care services in many previously disadvantaged regions, and increasing migration has promoted a new cultural diversity previously predominantly unicultural societies. This review explores current knowledge of similarities and differences in EOL practice between regions and possible causes and implications of these differences. ⋯ Awareness of differences, understanding their likely complex causes, and using this knowledge to inform individualized care at EOL is likely to improve the quality of care for patients. Further research should clarify the causes of EOL practice variability, monitor trends, and objectively evaluate the quality of EOL practice worldwide.

ReviewThe ethics of interventional procedures for patients too ill for surgery.
Minimally invasive interventional procedures are increasingly popular options for patients who are high-risk candidates for open surgical procedures. It is unclear how to proceed in the rare circumstance of a complication during an interventional procedure, where addressing the complication would require exposing the patient to the full risk that was being avoided with the minimally invasive technique. This review provides recommendations on how to approach this paradoxical scenario. ⋯ Interventional procedures, and emergent open surgery, should be offered as long as patients are fully informed about the benefits and risks, including the implications of potential life-sustaining treatments, and whether their respective goals of treatment are consistent with the intervention. Implementing this framework will require a cultural shift in physician attitudes to recognize that in some cases, nonintervention or less aggressive treatment may be a reasonable alternative to surgical intervention.
