Several studies have demonstrated that perioperative hemodynamic optimization has the ability to improve postoperative outcome in high-risk surgical patients. All of these studies aimed at optimizing cardiac output and/or oxygen delivery in the perioperative period. We conducted a survey with the American Society of Anesthesiologists (ASA) and the European Society of Anaesthesiology (ESA) to assess current hemodynamic management practices in patients undergoing high-risk surgery in Europe and in the United States. ⋯ In conclusion, these results point to a considerable gap between the accumulating evidence about the benefits of perioperative hemodynamic optimization and the available technologies that may facilitate its clinical implementation, and clinical practices in both Europe and the United States.

Understanding the nature and biological basis of gender-determined differences in risk of and outcome from infection might identify new therapeutic targets, allow more individualised treatment, and facilitate better risk prediction and application of healthcare resources. Gender differences in behaviours, comorbidities, access to healthcare and biology may result in differences in acquiring infection, or in response to infection once acquired. ⋯ Studying sufficient patient numbers to explore this entire continuum while accounting for heterogeneity in type of infection and comorbidity is difficult because of the number of patients required. However, if true gender effects can be identified, examination of their biological or psychosocial causes will be warranted.

Communication failures are a significant contributor to medical errors that harm patients. Critical care delivery is a complex system of inter-professional work that is distributed across time, space, and multiple disciplines. Because health-care education and delivery remain siloed by profession, we lack a shared framework within which we discuss and subsequently optimize patient care. ⋯ We suggest that the 'phases-of-illness paradigm' will facilitate communication about critically ill patients and create a shared mental model for interdisciplinary patient care. In so doing, this paradigm may reduce communication errors, complications, and costs while improving resource utilization and trainee education. Additional research applications are feasible.

Positioning of patients with acute respiratory distress syndrome: combining prone and upright makes sense.
Positional strategies have been proposed for mechanically ventilated patients with acute respiratory distress syndrome. Despite different physiological mechanisms involved, oxygenation improvement has been demonstrated with both prone and upright positions. ⋯ The combined positioning enhanced the response rate in terms of oxygenation. Other benefits, such as a reduction in ventilator-associated pneumonia and better enteral feeding tolerance, can potentially be expected.

The desperate need for good-quality clinical trials to evaluate the optimal source and dose of fibrinogen in managing bleeding.
Recent interest in transfusion management of trauma patients has heightened expectation in the role of blood component therapy in improving patient outcome. Optimal transfusion support in supplementation with fibrinogen has not been defined by high-quality evidence. ⋯ Studies of cost-effectiveness have not been considered in research. An international move to supplement fibrinogen more 'aggressively' without direct clinical evaluation beforehand represents a failed opportunity to improve our very limited understanding of optimal transfusion practice.
