Comparative Study
Hyperfibrinolysis after major trauma: differential diagnosis of lysis patterns and prognostic value of thrombelastometry.
The aim of this study was to diagnose hyperfibrinolysis (HF) and its pattern using thrombelastometry and to correlate the diagnosis with mortality. Furthermore, routine laboratory based and the rotational thrombelastometry analyzer (ROTEM)-derived variables were also correlated with survival. ⋯ ROTEM-based diagnosis of HF predicted outcome. Further independent predictors of death were combination of HF with hemorrhagic shock, low PC, and prolonged CFT in ROTEM. ROTEM-based point of care testing in the emergency room is thus able to identify prognostic factors such as prolonged CFT and low platelet contribution to clot firmness (MCF(EX) - MCF(FIB)) earlier than standard laboratory-based monitoring.

Randomized Controlled Trial Multicenter Study Comparative Study
Application of International Classification Injury Severity Score to National Surgical Quality Improvement Program defines pediatric trauma performance standards and drives performance improvement.
The American College of Surgeons National Surgical Quality Improvement Program is becoming a core methodology to define performance as a ratio of observed to expected events. We hypothesized that application of this using International Classification of Injury Severity Score (ICISS) for individual patient risk stratification to a group of hospitals contributing data to the National Pediatric Trauma Registry (NPTR) would apply objective evidence of actual injuries to define an expected standard and identify performance outliers. ⋯ Application of ICISS Ps from a national pediatric benchmark population simplifies determination of expected mortality necessary to compute the expected component of National Surgical Quality Improvement Program. Analysis of these ratios of expected to observed mortality demonstrates variance among centers, defines performance against peers using the same benchmarks, and can drive performance improvement based on the objective evidence of injury diagnoses actually encountered.

Comparative Study Clinical Trial
Single-dose etomidate for rapid sequence intubation may impact outcome after severe injury.
Etomidate is an induction agent used for the rapid sequence intubation (RSI) of trauma patients because of its favorable hemodynamic profile and rapid onset. However, recent studies have shown etomidate to decrease circulating cortisol concentrations, potentially influencing inflammation. We hypothesized that etomidate may alter the occurrence of acute respiratory distress syndrome (ARDS) in injury victims. ⋯ Single-dose etomidate for RSI in severely injured trauma patients is associated with increased ARDS and multiple organ dysfunction syndrome, in part, because of an effect of etomidate on the inflammatory response.

The utility of computed tomography as a screening tool for the evaluation of pediatric blunt chest trauma.
There is a growing concern that computed tomography (CT) is being unnecessarily overused for the evaluation of pediatric patients. The purpose of this study was to analyze the trends and utility of chest CT use compared with chest X-ray (CXR) for the evaluation of children with blunt chest trauma. ⋯ CT use in children has increased rapidly for the initial evaluation of chest trauma, whereas CXR use has decreased. Despite this trend, CXR remains an acceptable screening tool to analyze which patients may require CT evaluation. A multidisciplinary approach is warranted to develop guidelines that standardize the use of CT and thereby decreases unnecessary radiation exposure to pediatric patients.

Comparative Study
Race\ethnicity and outcome after traumatic brain injury at a single, diverse center.
Many factors may predict mortality and disability after traumatic brain injury (TBI), including age and injury severity. However, the role of race\ethnicity has typically been studied tangentially or in homogeneous settings. We investigated whether race\ethnicity was associated with medical outcomes at a single, diverse center. ⋯ The question of whether and how race plays a role in TBI is controversial. At a single, diverse center, we found that mortality is associated with race, age, and Injury Severity Score. Future clinical studies will benefit from detailed genotypic and phenotypic data and should balance larger sample sizes with ethnic diversity.
