Crotalid snake envenomation.

Over 5000 Americans suffer from snake bites annually, and of these, nearly one quarter are from poisonous species. Although these cases are undeniably reported, death appears to occur in only a few cases each year, and often reflects delay in obtaining medical care. Two families of venomous snake indigenous to the United States account for most envenomations: Crotalidae (pit vipers or new world vipers) and Elapidae. This article focuses on the snakes of the Crotalidae family.

Chemical warfare. Nerve agent poisoning.

The threat of civilian and military casualties from nerve agent exposure has become a greater concern over the past decade. After rapidly assessing that a nerve agent attack has occurred, emphasis must be placed on decontamination and protection of both rescuers and medical personnel from exposure. The medical system can become rapidly overwhelmed and strong emotional reactions can confuse the clinical picture. Initially, care should first be focused on supportive care, with emphasis toward aggressive airway maintenance and decontamination. Atropine should be titrated, with the goal of therapy being drying of secretions and the resolution of bronchoconstriction and bradycardia. Early administration of pralidoxime chloride maximizes antidotal efficacy. Benzodiazepines, in addition to atropine, should be administered if seizures develop. Early, aggressive medical therapy is the key to prevention of the morbidity and mortality associated with nerve agent poisoning.

Metered-dose inhalers: do emergency health care providers know what to teach?

STUDY OBJECTIVE: To evaluate the ability of emergency health care providers and patients to demonstrate the proper use of metered-dose inhalers (MDIs). DESIGN: Prospective cross-sectional survey. SETTING: Five Midwestern community teaching hospitals. PARTICIPANTS: One hundred eighty-five health care providers, comprising emergency medicine house staff (n = 60), attending emergency physicians (n = 50), and ED nurses (n = 75). Also recruited were 100 consecutive ED patients with clinical history of asthma being treated with at least one MDI for more than 3 months. INTERVENTIONS: We surveyed patients and health care providers to assess their knowledge of and ability to use a conventional MDI. The subject's technique of using a placebo inhaler was graded by a trained observer using a checklist of six essential steps. RESULTS: Forty-one percent (76 of 185) of health care providers and 49% (49 of 100) of ED asthma patients performed at least five steps correctly (P = .24). There were no significant differences in performance scores among the emergency medicine house staff (42%), attending emergency physicians (34%), and ED nurses (45%). Only 15% of all health care providers and 17% of asthma patients were able to describe how to estimate the amount of medicine left in the canister. CONCLUSION: These results suggest that many patients use MDIs improperly. Emergency physicians, house staff, and nurses responsible for instructing patients in optimal inhaler use may lack even rudimentary skills with these devices.
