To determine if peripheral venous blood gas values for pH, partial pressure of carbon dioxide (Pco(2)) and the resultant calculated bicarbonate (HCO(3)) predict arterial values accurately enough to replace them in a clinical setting. ⋯ Arterial and venous blood gas samples were strongly correlated, and there were only small differences between them. A survey of emergency physicians suggested that the differences are too large to allow for interchangeability of results; however, venous values may be valid if used in conjunction with a correction factor or for trending purposes.

To determine the inter-observer agreement on triage assignment by first-time users with diverse training and background using the Canadian Emergency Department Triage and Acuity Scale (CTAS). ⋯ Despite minimal experience with the CTAS, inter-observer agreement among emergency care providers with different backgrounds was significant.

Most emergency departments (EDs) have deficiencies in the type and quantity of antidotes readily available to treat severely poisoned patients. Undue emphasis on the purchase price of several expensive antidotes such as anti-digoxin F(ab) fragments and fomepizole may contribute to this problem by creating the perception that comprehensive antidote stocking is too costly for smaller centres. For rarely used medications, however, purchase price alone is an insufficient estimate of cost. ⋯ While other factors (antidote efficacy, safety and available alternate therapy) need to be considered, the cost of maintaining antidote availability is not determined primarily by purchase price. A change in supplier policy to free replacement on expiry for fomepizole and cyanide antidotes would have a considerable effect on making these antidotes less costly for smaller Canadian EDs.

Ethical issues can be more difficult to address in the emergency department than in other settings. We present two cases, with the goal of stimulating moral reflection and encouraging emergency physicians to gain a better understanding of two important ethical issues: advance directives and resource allocation decisions. ⋯ Although patients or substitute decision-makers define the value of a treatment goal, emergency physicians must ensure that this goal does indeed represent the patient's wishes, that it is achievable, and that competing claims for the same resource are considered. Learning from others' experiences and preparing for ethical problems in advance will help physicians feel more comfortable in dealing with ethical issues.
