2013 Aug - Early Acute Lung Injury: Criteria for Identifying Lung Injury Prior to the Need for Positive Pressure Ventilation
Levitt, Joseph E.; Calfee, Carolyn S.; Goldstein, Benjamin A.; Vojnik, Rosemary; Matthay, Michael A.; Critical Care Medicine. 41(8):1929-1937, August 2013.
Objective: Mortality associated with acute lung injury remains high. Early identification of acute lung injury prior to onset of respiratory failure may provide a therapeutic window to target in future clinical trials. The recently validated Lung Injury Prediction Score identifies patients at risk for acute lung injury but may be limited for routine clinical use. We sought to empirically derive clinical criteria for a pragmatic definition of early acute lung injury to identify patients with lung injury prior to the need for positive pressure ventilation.
2013 Aug - Effect of Plasma-to-RBC Ratios in Trauma Patients: A Cohort Study With Time-Dependent Data
Halmin, Märit; Boström, Fredrik; Brattström, Olof; Lundahl, Joachim; Wikman, Agneta; Östlund, Anders; Edgren, Gustaf; Critical Care Medicine. 41(8):1905-1914, August 2013.
Background: A widespread approach today is to transfuse bleeding trauma patients with RBC concentrates and plasma at a 1:1 ratio. This regime is supported by a range of observational studies showing lower mortality in bleeding patients receiving equal volumes of plasma and RBCs. The rationale for this practice is still unclear with several studies failing to show any survival benefits of increased plasma use, perhaps due to a failure to account for the timing of transfused units.

The aim of this study was to describe the clinical characteristics, treatments, and outcomes of critically ill patients with Shiga toxin–producing E. coli–associated hemolytic uremic syndrome during this outbreak.
2013 Jul - Standardized Endoscopic Swallowing Evaluation for Tracheostomy Decannulation in Critically Ill Neurologic Patients
Warnecke, Tobias; Suntrup, Sonja; Teismann, Inga K.; Hamacher, Christina; Oelenberg, Stephan; Dziewas, Rainer; Critical Care Medicine. 41(7):1728-1732, July 2013.
Objectives: Decisions regarding tracheostomy tube removal after mechanical ventilation often depend on the physician’s individual experience because evidence-based practice guidelines are still scarce, especially for critically ill neurologic patients. In these patients, the prevalence of aspiration is high and regarded as an important contributor to decannulation failure. The presence of severe neurological deficits may, however, give clinicians the subjective impression that a tracheostomy tube is still necessary although decannulation may actually be safe. It is therefore crucial to test swallowing function reliably prior to decannulation in this patient population.
2013 Jul - The Influence of Prehospital Systemic Corticosteroid Use on Development of Acute Respiratory Distress Syndrome and Hospital Outcomes
Karnatovskaia, Lioudmila V.; Lee, Augustine S.; Gajic, Ognjen; Festic, Emir; on behalf of U.S. Critical Illness and Injury Trials Group: Lung Injury Prevention Study Investigators (USCIITG–LIPS); Critical Care Medicine. 41(7):1679-1685, July 2013.
Objective: The role of systemic corticosteroids in pathophysiology and treatment of acute respiratory distress syndrome is controversial. Use of prehospital systemic corticosteroid therapy may prevent the development of acute respiratory distress syndrome and improve hospital outcomes.
2013 Jul - Early Antibiotic Discontinuation in Patients With Clinically Suspected Ventilator-Associated Pneumonia and Negative Quantitative Bronchoscopy Cultures
Raman, Kirthana; Nailor, Michael D.; Nicolau, David P.; Aslanzadeh, Jaber; Nadeau, Michelle; Kuti, Joseph L.; Critical Care Medicine. 41(7):1656-1663, July 2013.
Objectives: Preliminary data suggest that antibiotic discontinuation in patients with negative quantitative bronchoscopy and symptom resolution will not increase mortality. Because our hospital algorithm for antibiotic discontinuation rules out ventilator-associated pneumonia in the setting of negative quantitative bronchoscopy cultures, we compared antibiotic utilization and mortality in empirically treated, culture-negative ventilator-associated pneumonia patients whose antibiotic discontinuation was early versus late.
2013 Jul - Venoarterial Extracorporeal Membrane Oxygenation Support for Refractory Cardiovascular Dysfunction During Severe Bacterial Septic Shock
Bréchot, Nicolas; Luyt, Charles-Edouard; Schmidt, Matthieu; Leprince, Pascal; Trouillet, Jean-Louis; Léger, Philippe; Pavie, Alain; Chastre, Jean; Combes, Alain; Critical Care Medicine. 41(7):1616-1626, July 2013.
Objectives: Profound myocardial depression can occur during severe septic shock. Although good outcomes of venoarterial extracorporeal membrane oxygenation–treated children with refractory septic shock have been reported, little is known about adults’ outcomes. This study was designed to assess the outcomes and long-term health-related quality-of-life of patients supported by venoarterial extracorporeal membrane oxygenation for refractory cardiac and hemodynamic failure during severe septic shock.
