This article is adapted from a presentation given at the 1999 SAEM annual meeting by Dr. Peter Safar. Dr. ⋯ Current controversies, such as how to best educate the public in life-supporting first aid, how to restore normotensive spontaneous circulation after cardiac arrest, how to rapidly induce mild hypothermia for cerebral protection, and how to minimize secondary insult after cerebral ischemia, are discussed, and must be resolved if advances are to be made. Dr. Safar also summarizes future technologies already under preliminary investigation, such as ultra-advanced life support for reversing prolonged cardiac arrest, extending the "golden hour" of shock tolerance, and suspended animation for delayed resuscitation.

Optimal use of emergency diagnostic and treatment unit (EDTU) resources for treatment of acute asthma should be facilitated by the selection of patients with a high probability of discharge from the EDTU. The study goal was to identify characteristics of the patient or exacerbation that could be used to predict recovery of pulmonary function within 12 hours. ⋯ A simple objective measure of pulmonary function early in treatment discriminated among those with high, low, and intermediate probabilities of achieving a specified level of PEFR within 12 hours. Awareness of this probability could assist clinicians attempting to predict discharge from the EDTU and facilitate decision making regarding utilization of EDTU resources.

Burn depth and extent determine prognosis and therapy. The current classification into first-, second-, and third-degree burns is crude, making comparisons between studies difficult. The authors standardized a reproducible burn model and a precise histopathologic method for describing burn depth in swine. ⋯ The authors describe a simple and reproducible animal burn model and histopathologic scale for measuring burn depth that they believe will facilitate standardization and comparison within future burn studies.

Previous studies have demonstrated that the public maintains unrealistic expectations of the potential for successful recovery following administration of cardiopulmonary resuscitation (CPR). Others have attributed this phenomenon to misrepresentation of CPR outcomes on television and other sources of public information. ⋯ Regardless of the source, the public is not accurately informed about the effectiveness of CPR. This creates a situation in which people may elect CPR for themselves or for family members when survival, not to mention recovery, is unlikely. Without dissemination of realistic statistics regarding survival and recovery following CPR, the public will maintain unrealistic expectations of CPR, and be unable to make well-informed decisions concerning its use.

To determine the criteria used by emergency medicine (EM) residency selection committees to select their residents, to determine whether there is a consensus among residency programs, to inform programs of areas of possible inconsistency, and to better educate applicants pursuing careers in EM. ⋯ The selection criteria with the highest mean values as reported by the program directors were EM rotation grade, interview, clinical grades, and recommendations. Criteria showing the most consistency (lowest SD) included EM rotation grade, interview, and clinical grades. Results are compared with those from previous multispecialty studies.
