Randomized Controlled Trial Comparative Study
Procedures can be learned on the Web: a randomized study of ultrasound-guided vascular access training.
Web-based learning has several potential advantages over lectures, such as anytime-anywhere access, rich multimedia, and nonlinear navigation. While known to be an effective method for learning facts, few studies have examined the effectiveness of Web-based formats for learning procedural skills. The authors sought to determine whether a Web-based tutorial is at least as effective as a didactic lecture for learning ultrasound-guided vascular access (UGVA). ⋯ Our Web-based tutorial was at least as effective as a traditional didactic lecture for teaching the knowledge and skills essential for UGVA. Participants expressed high satisfaction with this teaching technology. Web-based teaching may be a useful alternative to didactic teaching for learning procedural skills.

Multicenter Study
Prospective multicenter bronchiolitis study: predicting intensive care unit admissions.
The authors sought to identify predictors of intensive care unit (ICU) admission among children hospitalized with bronchiolitis for > or =24 hours. ⋯ In this prospective multicenter ED-based study of children admitted for bronchiolitis, four independent predictors of ICU admission were identified. The authors did not confirm many putative risk factors, but cannot rule out modest associations.

The objective was to determine if hospital admission of children with blunt abdominal trauma for observation of possible intraabdominal injury (IAI) is necessary after a normal abdominal computed tomography (CT) scan in the emergency department (ED). ⋯ Children with blunt abdominal trauma and a normal abdominal CT scan in the ED are at very low risk of having a subsequently diagnosed IAI and are very unlikely to require a therapeutic intervention. Hospitalization of children for evaluation of possible undiagnosed IAI after a normal abdominal CT scan has a low yield and is generally unnecessary.

The objective was to determine effects of a modification in triage process on triage acuity distribution in general and among patients with conditions requiring time-sensitive therapy. ⋯ Monitoring for changes in the sensitivity of the triage process for detecting patients with potentially time-sensitive conditions should be considered when modifying triage processes. Further work should be done to determine if the decreased sensitivity seen in this study occurs in other institutions converting to ESI, and potential causative factors should be explored.

A systemic inflammatory response has been reported following resuscitation from cardiac arrest. The purpose of this study was to compare the magnitude of the tumor necrosis factor-alpha (TNF-alpha) response in two different swine models of ventricular fibrillation (VF) arrest. ⋯ This study demonstrates that TNF-alpha concentrations increase after resuscitation from cardiac arrest and that the TNF-alpha response is more profound in animals subjected to ischemic, spontaneous VF. The observed differences may be due to a longer resuscitation time and persistent postresuscitation hypoperfusion in the ischemic VF group. These differences need to be considered in studies evaluating mechanisms of postresuscitation organ dysfunction and defining mortality markers.
