The sepsis resuscitation bundle is the result of an effort on behalf of the Surviving Sepsis Campaign and the Institute for Healthcare Improvement to translate individual guideline recommendations into standardized, achievable goals for physicians caring for the critically ill patient. Implementation of this bundle is associated with decreased mortality. ⋯ Elevations in serum lactate are associated with increased mortality, and may result from either increased lactate production or impaired lactate clearance. Lactate clearance may be an important addition to the monitoring and management bundles of patients with severe sepsis and septic shock, However, specific mechanisms of lactate clearance, the relation of lactate clearance to traditional hemodynamic parameters, and the importance of lactate clearance as a therapeutic target or monitoring tool remain unclear.

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.

The recent advent of consensus definitions for acute kidney injury (AKI) has led to improvement in epidemiology of this complex disease and facilitated the development of new diagnostic makers and new therapies. However, important new challenges are also apparent. ⋯ Progress in this area will require new ideas and thinking outside the conventional box. By confronting some of the most significant controversies in the field of AKI we seek to develop new concepts that will ultimately yield new results.

Protein C plays an important role in the coagulopathy associated with sepsis and probably also in the pathogenesis of sepsis-induced organ dysfunction. Plasma levels of protein C strongly correlate with clinical outcome in patients with severe sepsis. The RESPOND (Research Evaluating Serial Protein C Levels in Severe Sepsis Patients on Drotrecogin Alfa [Activated]) study shows that administration of recombinant human activated protein C in patients with severe sepsis with alternative dose regimens adjusted to plasma levels of protein C results in higher plasma levels of protein C. This may potentially translate to a better clinical outcome in patients with severe sepsis, although that was not directly shown in this trial.

Terblanche and colleagues add to the ongoing controversy over the role, if any, for statins in patients with sepsis. The authors note that statins fail to prevent progression to organ dysfunction in critically ill patients. However, like most publications, the study is retrospective and stimulates the controversy but fails to resolve it. The time has come for robust randomized controlled clinical trials.
