OBJECTIVES Learn how to perform a rapid assessment of a nerve agent terrorism situation. Recognize characteristic signs and symptoms of nerve agent poisoning. OBJECTIVES Understand proper decontamination for nerve agent poisoning. Learn medical management of nerve agent exposed victims. Learn specific antidotes for nerve agent poisoning victims. ScenarioFriday, January 31 – 8:47 AM (Rush Hour) An unknown gas is released in the downtown rapid transit station. It is described as a thick mist, and was found in 5 separate stops. Thousands of commuters rapidly fled the stations to the streets. EMS transport is overwhelmed, and several local ED’s are unable to absorb the patients presenting by ambulance, car, taxi, and on foot. Many patients present to offices and local health departments. ScenarioFriday, January 31 – 10:02 AM One patient that presents to a local health clinic complains of tearing and runny nose. He also has mild shortness of breath. Mild wheeze is noted on exam. Ten other patients at the clinicare asymptomatic, but are very worried. ScenarioFriday, January 31 – 10:27 AM Public health officials confirm that the gas was Sarin, similar to the toxin used in the subway of Tokyo. Things to Consider Has your staff been adequately trained about chemical weapons? Does your staff understand basic principles of decontamination? Who should your staff alert? Who will alert your staff in the event of a chemical terrorism event? Nerve Agents Characteristics of Nerve Agents Liquids that disseminate in the vapor/aerosolized form Onset is abrupt (seconds to hours) Designed to irritate, incapacitate, injure or kill Predominantly inhalational and dermal threats If death occurs, usually respiratory cause Characteristics of Nerve Agents Chemical incidents are obvious shortly after exposure. Biological agents will take days to cause symptoms. ONE patient can contaminate your facility First responders/health care providers are in the line of fire First used
