1) To describe injuries experienced by the male prisoner population in the Kingston, Ontario area, and to compare them with those observed in the general population; and 2) to compare the incidence and patterns of prisoner injuries seen in emergency departments (EDs) before and after the introduction of a prison injury triage system. ⋯ The introduction of the new triage system appeared to be associated with a decrease in the total number of ED visits by prisoners. The relative acuity of prisoner injuries seen in the EDs appeared to increase following introduction of the triage system.

This paper outlines some of the ethical and practical dilemmas of securing true informed consent in resuscitation research in the prehospital or emergency department setting. Possible substitutes to such consent are discussed and evaluated. The Canadian Tri-Council Policy Statement guidelines for emergency medicine research are compared to the US Food and Drug Administration rules, and the former are assessed and critiqued. Modifications to the current Tri-Council guidelines are suggested.

Atenolol, a selective beta(1)-adrenergic antagonist, is commonly used to treat hypertension, ischemic heart disease and cardiac dysrhythmias. Few cases of severe atenolol intoxication have been described, and only one of these reports discussed the use of calcium chloride as a treatment. We present a case of atenolol overdose associated with shock and first-degree heart block, in which administration of calcium chloride led to dramatic improvement after failure of conventional treatment. In addition, we discuss the pharmacokinetics, toxicology and management of beta-blocker overdose, focusing on the possible role of calcium chloride.

Acute upper gastrointestinal (UGI) hemorrhage is a common, often serious condition encountered in the emergency department (ED). Previous research has suggested that transfusion of blood products may interfere with the hypercoagulable state induced by significant blood loss. Our objective was to determine whether the frequency of rebleeding is higher in patients with UGI bleeding who have received early blood transfusion. ⋯ Our results support previous research suggesting that transfused UGI bleed patients have a higher rate of rebleeding. However, because of the retrospective design, causality cannot be inferred.
