Review Meta AnalysisEtomidate is associated with mortality and adrenal insufficiency in sepsis: a meta-analysis*.
To evaluate the effects of single-dose etomidate on the adrenal axis and mortality in patients with severe sepsis and septic shock. ⋯ Administration of etomidate for rapid sequence intubation is associated with higher rates of adrenal insufficiency and mortality in patients with sepsis.

Review Meta AnalysisEfficacy spectrum of antishivering medications: meta-analysis of randomized controlled trials.
Shivering after anesthesia or in the critical care setting is frequent, can be prolonged, and has the potential for serious adverse events and worsening outcomes. Furthermore, there are conflicting published data and clinical protocols on how to best treat shivering. In this study, we aimed to critically analyze the published evidence of antishivering medications. ⋯ There is significant heterogeneity in the literature with respect to study methods and efficacy testing of antishivering treatments. Clonidine, meperidine, tramadol, nefopam, and ketamine were the most frequently reported pharmacological interventions and showed a variable degree of efficacy in randomized, double-blinded, placebo-controlled trials.

Multicenter StudyActivated protein C and septic shock: a propensity-matched cohort study*.
Septic shock is a highly inflammatory and procoagulant state associated with significant mortality. In a single randomized controlled trial, recombinant human activated protein C (drotrecogin alfa) reduced mortality in patients with severe sepsis at high risk of death. Further clinical trials, including a recently completed trial in patients with septic shock, failed to reproduce these results. ⋯ In this retrospective, propensity-matched, multicenter cohort study of patients with septic shock, early use of recombinant human activated protein C was associated with reduced mortality. Improvements in general quality of care such as speed of antimicrobial delivery leading to decreasing mortality of patients with septic shock may have contributed to the null results of the recently completed trial of recombinant human activated protein C in patients with septic shock.

Prevalence and outcomes of pediatric in-hospital cardiopulmonary resuscitation in the United States: an analysis of the Kids' Inpatient Database*.
Population-based data on pediatric in-hospital cardiopulmonary resuscitation in the United States are scarce. Single-center studies and voluntary registries may skew the estimated prevalence and outcomes. This study aimed to determine the prevalence and outcomes of pediatric cardiopulmonary resuscitation on a national scale. ⋯ Cardiopulmonary resuscitation is performed in approximately one in 1,300 pediatric hospitalizations. Approximately half of patients receiving cardiopulmonary resuscitation do not survive to discharge. Independent risk factors for mortality after receiving cardiopulmonary resuscitation included congenital heart disease, age ≥1 yr, acute renal failure, hepatic insufficiency, and sepsis.

The effects of a newly developed miniaturized mechanical chest compressor on outcomes of cardiopulmonary resuscitation in a porcine model*.
When the duration of cardiac arrest is prolonged, reperfusion of the vital organs by effective chest compression is the most important intervention for successful resuscitation. We investigated the effects of a newly developed miniaturized chest compressor on the outcomes of cardiopulmonary resuscitation. ⋯ The miniaturized chest compressor improves hemodynamic efficacy and the success of cardiopulmonary resuscitation with significantly less injury, which is as effective as the LUCAS device. It may provide a new option for cardiopulmonary resuscitation.
