Extravascular lung water and the pulmonary vascular permeability index may improve the definition of ARDS.
The recent Berlin definition has made some improvements in the older definition of acute respiratory distress syndrome (ARDS), although the concepts and components of the definition remained largely unchanged. In an effort to improve both predictive and face validity, the Berlin panel has examined a number of additional measures that may reflect increased pulmonary vascular permeability, including extravascular lung water. ⋯ By using extravascular lung water and the pulmonary vascular permeability index, both of which are derived from transpulmonary thermodilution, the authors could successfully differentiate between patients with ARDS and other patients in respiratory failure due to either cardiogenic edema or pleural effusion with atelectasis. This commentary discusses the merits and limitations of this study in view of the potential improvement that transpulmonary thermodilution may bring to the definition of ARDS.

During the past 50 years, caring for the critically ill has become increasingly complex and the need for an intensivist has become more evident. Management by intensivists has become a quality indicator for many ICUs. Numerous small studies have demonstrated the beneficial effect of intensivists on outcomes in the critically ill, and some clinicians have advanced the argument that a night-time intensivist is essential for the care of critically ill patients. ⋯ In this methodologically rigorous trial, there was no difference in outcomes between the intensivist and control group, which consisted of in-house resident coverage at night with availability by telephone of fellows and intensivists. These two robust studies clearly suggest that night-time intensivists do not improve mortality in ICUs managed by intensivists during the day. Though possibly beneficial in low-intensity environments, the widespread drive to add night-time intensivist coverage may have been premature.

A week seems to be weak: tailoring duration of antibiotic treatment in Gram-negative ventilator-associated pneumonia.
The optimal length of antimicrobial therapy has not been extensively studied for a great majority of infections and, in critically ill patients affected by ventilator-associated pneumonia, is a persisting and unsolved issue confronting clinicians. The integration of biomarkers, clinical judgment, and microbiologic eradication might help to define a shorter duration for some ventilator-associated pneumonia episodes due to non-fermenting Gram-negative bacilli, but until these strategies are implemented in clinical practice for individualizing antibiotic treatment, a short-course duration does not seem to tailor a long benefit.

How do we know when patients sleep properly or why they do not?
The importance of adequate sleep for good health and immune system function is well documented as is reduced sleep quality experienced by ICU patients. In the previous issue of Critical Care, Elliot and co-workers present a well done, largest of its kind, single-center study on sleep patterns in critically ill patients. They base their study on the 'gold standard', the polysomnography technique, which is resource demanding to perform and often difficult to evaluate. ⋯ Sound disturbance was found to be the most significant but improvable factor. The study highlights the challenge and the importance of evaluating sleep in the critical care setting and the present need for alternative methods to measure it. All that in conjunction can be used to solve an important problem for this patient group.

According to the World Health Organization, traumatic injuries worldwide are responsible for over 5 million deaths annually. Post-traumatic bleeding caused by traumatic injury-associated coagulopathy is the leading cause of potentially preventable death among trauma patients. ⋯ The STOP the Bleeding Campaign therefore aims to increase awareness of the phenomenon of post-traumatic coagulopathy and its appropriate management by publishing European guidelines for the management of the bleeding trauma patient, by promoting and monitoring the implementation of these guidelines and by preparing promotional and educational material, organising activities and developing health quality management tools. The campaign aims to reduce the number of patients who die within 24 hours after arrival in the hospital due to exsanguination by a minimum of 20% within the next 5 years.
