Review
Ondansetron and the Risk of Cardiac Arrhythmias: A Systematic Review and Postmarketing Analysis.
To explore the risk of cardiac arrhythmias associated with ondansetron administration in the context of recent recommendations for identification of high-risk individuals. ⋯ Current evidence does not support routine ECG and electrolyte screening before single oral ondansetron dose administration to individuals without known risk factors. Screening should be targeted to high-risk patients and those receiving ondansetron intravenously.

The death of a child in the emergency department (ED) is one of the most challenging problems facing ED clinicians. This revised technical report and accompanying policy statement reaffirm principles of patient- and family-centered care. Recent literature is examined regarding family presence, termination of resuscitation, bereavement responsibilities of ED clinicians, support of child fatality review efforts, and other issues inherent in caring for the patient, family, and staff when a child dies in the ED. Appendices are provided that offer an approach to bereavement activities in the ED, carrying out forensic responsibilities while providing compassionate care, communicating the news of the death of a child in the acute setting, providing a closing ritual at the time of terminating resuscitation efforts, and managing the child with a terminal condition who presents near death in the ED.

Diethylene glycol is a toxic industrial solvent responsible for more than 13 mass poisonings since 1937. Little is known about the clinical spectrum, progression, and neurotoxic potential of diethylene glycol-associated disease because of its high mortality and the absence of detailed information in published mass poisoning reports. This incident includes the largest proportion of cases with neurotoxic signs and symptoms. We characterize the features of a diethylene glycol mass poisoning resulting from a contaminated cough syrup distributed in Panama during 2006. ⋯ A high proportion of patients with diethylene glycol poisoning developed progressive neurologic signs and symptoms in addition to acute kidney injury. Facial or limb weakness with unexplained acute kidney injury should prompt clinicians to consider diethylene glycol poisoning. Elevated cerebrospinal fluid protein concentrations without pleocytosis among diethylene glycol-exposed persons with acute kidney injury may be a predictor for progressive neurologic illness.

Comparative Study
Pretreatment With Intravenous Lipid Emulsion Reduces Mortality From Cocaine Toxicity in a Rat Model.
We compare the effects of intravenous lipid emulsion and normal saline solution pretreatment on mortality and hemodynamic changes in a rat model of cocaine toxicity. We hypothesize that intravenous lipid emulsion will decrease mortality and hemodynamic changes caused by cocaine administration compared with saline solution. ⋯ Intravenous lipid emulsion pretreatment decreased cocaine-induced cardiovascular collapse and blunted hypotensive effects compared with normal saline solution in this rat model of acute lethal cocaine intoxication. Intravenous lipid emulsion should be investigated further as a potential adjunct in the treatment of severe cocaine toxicity.

Case Reports
Temporization of Penetrating Abdominal-Pelvic Trauma With Manual External Aortic Compression: A Novel Case Report.
A young civilian man experienced multiple gunshots to the lower abdomen, pelvis, and thigh. These were not amenable to direct compression by a single rescuer. This report outlines the first case in the peer-reviewed literature of manual external aortic compression after severe trauma. ⋯ Research is needed to test our presumption that successful bimanual compression requires larger-weight rescuers, smaller-weight victims, and a hard surface. It is therefore unclear whether manual external aortic compression is achievable by most rescuers or for most victims. However, it offers an immediate and equipment-free life-sustaining strategy when there are limited alternatives.
