N Engl J Med 2012, 367:1901-1911. ⋯ In patients in the ICU, there was no significant difference in 90-day mortality between patients resuscitated with 6% HES (130/0.4) or saline. However, despite a lower overall rate of AKI, more patients who received resuscitation with HES were given renal replacement therapy. (The study was supported by the National Health and Medical Research Council of Australia; the Ministry of Health, New South Wales Government, Australia; and Fresenius Kabi; and by a Practitioner Fellowship from the National Health and Medical Research Council of Australia (to Drs Myburgh and Bellomo), by a Principal Research Fellowship from the National Health and Medical Research Council of Australia (to Dr Cass), and by a Practitioner Fellowship from the Medical Research Foundation of the Royal Perth Hospital (to Dr Webb); CHEST ClinicalTrials.gov number NCT00935168.).

Randomized Controlled Trial Multicenter Study Comparative Study
A French multicenter randomised trial comparing two dose-regimens of prothrombin complex concentrates in urgent anticoagulation reversal.
Prothrombin complex concentrates (PCC) are haemostatic blood preparations indicated for urgent anticoagulation reversal, though the optimal dose for effective reversal is still under debate. The latest generation of PCCs include four coagulation factors, the so-called 4-factor PCC. The aim of this study was to compare the efficacy and safety of two doses, 25 and 40 IU/kg, of 4-factor PCC in vitamin K antagonist (VKA) associated intracranial haemorrhage. ⋯ Rapid infusion of both doses of 4-factor PCC achieved an INR of 1.5 or less in all patients with a lower INR observed in the 40 IU/kg group. No safety concerns were raised by the 40 IU/kg dose. Further trials are needed to evaluate the impact of the high dose of 4-factor PCC on functional outcomes and mortality.

Multicenter Study Observational Study
The effect of excess fluid balance on the mortality rate of surgical patients: a multicenter prospective study.
In some studies including small populations of patients undergoing specific surgery, an intraoperative liberal infusion of fluids was associated with increasing morbidity when compared to restrictive strategies. Therefore, to evaluate the role of excessive fluid infusion in a general population with high-risk surgery is very important. The aim of this study was to evaluate the impact of intraoperative fluid balance on the postoperative organ dysfunction, infection and mortality rate. ⋯ Patients with excessive intraoperative fluid balance have more ICU complications and higher hospital mortality.

Randomized Controlled Trial Multicenter Study
The efficacy of thymosin alpha 1 for severe sepsis (ETASS): a multicenter, single-blind, randomized and controlled trial.
Severe sepsis is associated with a high mortality rate despite implementation of guideline recommendations. Adjunctive treatment may be efficient and require further investigation. In light of the crucial role of immunologic derangement in severe sepsis, thymosin alpha 1 (Tα1) is considered as a promising beneficial immunomodulatory drug. The trial is to evaluate whether Tα1 improves 28-day all-cause mortality rates and immunofunction in patients with severe sepsis. ⋯ The use of Tα1 therapy in combination with conventional medical therapies may be effective in improving clinical outcomes in a targeted population of severe sepsis.

Randomized Controlled Trial
Continuous positive airway pressure and ventilation is more effective with a nasal mask than a full face mask in unconscious subjects: a randomized controlled trial.
Upper airway obstruction (UAO) is a major problem in unconscious subjects, making full face mask ventilation difficult. The mechanism of UAO in unconscious subjects shares many similarities with that of obstructive sleep apnea (OSA), especially the hypotonic upper airway seen during rapid eye movement sleep. Continuous positive airway pressure (CPAP) via nasal mask is more effective at maintaining airway patency than a full face mask in patients with OSA. We hypothesized that CPAP via nasal mask and ventilation (nCPAP) would be more effective than full face mask CPAP and ventilation (FmCPAP) for unconscious subjects, and we tested our hypothesis during induction of general anesthesia for elective surgery. ⋯ nCPAP produced more effective tidal volume than FmCPAP in unconscious subjects.
