Comparative Study
A retrospective comparison of ketamine dosing regimens for pediatric procedural sedation.
Ketamine is a dissociative agent often used in pediatric emergency departments for procedural sedation. Institutions commonly use either 1.5 mg/kg (k1.5) or 1 mg/kg (k1.0) as intravenous dosing. We sought to determine whether patients receiving k1.0 require more administered doses during sedation than patients receiving k1.5. Furthermore, we examined whether differences existed between k1.0 and k1.5 in the total dosage, total mg/kg, and time to recovery. ⋯ Sedations using k1.5 require fewer doses, lower mg/kg administered, but a higher total dose than k1.0. No difference was found in the rate of adverse events between the groups. Our findings suggest that ketamine sedations can be completed safely with one dose when patients are initially dosed at 1.5 mg/kg.

Randomized Controlled Trial Comparative Study
Virtual reality and live simulation: a comparison between two simulation tools for assessing mass casualty triage skills.
This study tested the hypothesis that virtual reality simulation is equivalent to live simulation for testing naive medical students' abilities to perform mass casualty triage using the Simple Triage and Rapid Treatment (START) algorithm in a simulated disaster scenario and to detect the improvement in these skills after a teaching session. ⋯ Virtual reality simulation proved to be a valuable tool, equivalent to live simulation, to test medical students' abilities to perform mass casualty triage and to detect improvement in such skills.

Over the past few years, the number of patients attending emergency services has increased steadily. As a result, emergency departments (EDs) worldwide face frequent crowding, with the risk of reduced treatment quality and impaired patient outcome, patient and staff dissatisfaction and inefficient use of ED resources. A qualitative process analysis and process modelling was used as a method to detect critical process steps in the ED with respect to time and efficiency. ⋯ The process analysis helped to identify inefficient process steps in the ED. Modelling with EPC is a useful tool to visualize and to understand the complexity of the emergency medical care and to identify key performance indicators for effective quality management.

The objective of this study was to investigate the accuracy of renal point of care ultrasound (POCUS) for the detection of hydronephrosis in children with a urinary tract infection (UTI). We prospectively included all patients with a final diagnosis of UTI who visited our pediatric emergency department between November 2009 and April 2011. Emergency physicians were encouraged to perform a renal POCUS during these visits, and a follow-up renal ultrasonography was performed by a radiologist who was blinded to the results of POCUS. ⋯ The sensitivity and the specificity were 76.5% (95% confidence interval: 58.1-94.6%) and 97.2% (95.2-99.2%), respectively. The positive and the negative predictive values were 59.1% (36.4-79.3%) and 98.8% (97.7-99.9%), respectively. Renal POCUS might be used to rule out hydronephrosis in pediatric UTI.
