The study by Dr Peiniger and colleagues in a recent issue of Critical Care indicates that transfusion strategies using an early and more balanced ratio between fresh frozen plasma and red blood cell transfusions provide a survival benefit in patients with acute traumatic coagulopathy requiring massive transfusion within the first 24 hours of hospitalization. However, this topic has never been explored in depth in patients with concomitant severe traumatic brain injury. While the study is retrospective and certainly not a substitute for a well-designed prospective trial, the authors nonetheless should be commended for addressing this issue with their current work. Currently, the optimum fluid resuscitation paradigm for patients with both severe traumatic brain injury and other injuries requiring significant volume resuscitation is not clear.

Severe community-acquired pneumonia is a major cause of admission to intensive care units and its mortality rates remain exceedingly high. In the search for adjunctive therapies, clinicians who were encouraged by available, though limited, evidence prescribed steroids in most patients with severe sepsis or septic shock, including those with community-acquired pneumonia. Current evidence demonstrates that, whereas corticosteroids should not be routinely employed as adjuvant therapy for severe community-acquired pneumonia, there is sufficient equipoise to continue studying the use of corticosteroids.

The purpose of our study was to determine whether hypothermia has any effects on physiological hemodynamic responses to epinephrine (Epi), and whether rewarming reverses these effects. ⋯ This study shows that hypothermia causes a change in the physiological hemodynamic response to Epi, which is not reversed by rewarming.
