No specific antidote is available for T-2 mycotoxin exposure. Provide supportive measures, addressing respiratory and cardiovascular status as necessary. If the patient complains of eye pain or tearing, irrigate the eyes with copious amounts of water.
What type of nerve agent is the most persistent?
VX is the least volatile of the nerve agents, which means that it is the slowest to evaporate from a liquid into a vapor. Therefore, VX is persistent in the environment.
How is the victim of a pulmonary agent exposure?
A pulmonary agent, or choking agent, is a chemical weapon agent designed to impede a victim's ability to breathe. They operate by causing a build-up of fluids in the lungs, which then leads to suffocation. Exposure to the eyes and skin tends to be corrosive, causing blurred vision and severe deep burns.
How is the victim of nerve agent exposure presenting?
How is the victim of nerve agent exposure presenting with convulsions classified? Eyes are the most vulnerable to this agent due to their thin, moist, warm mucosa.
What phase is characterized by improvement of symptoms that become shorter with increasing doses?
Latent phase: is a delusive phase characterized by improvement of symptoms and an apparent cure.
What specific antidote is available for pulmonary weapon agents?
Decontamination is not usually necessary for people exposed to vapor or gas, and there are no specific antidotes for these agents.
What is the preferred treatment to block the effects of excessive ACh?
One of the treatment modalities for myasthenia gravis is the use of acetylcholinesterase inhibitors (AChEI) such as pyridostigmine. AChEI prevents the breakdown of ACh by inactivating AChE. This stops the breakdown of ACh and increases its level and duration of action at the postsynaptic membrane.
How do you treat exposure to nerve gas?
Washing the body:As quickly as possible, wash any liquid sarin from the skin with large amounts of soap and water. Washing with soap and water will help protect people from any chemicals on their bodies.Rinse the eyes with plain water for 10 to 15 minutes if they are burning or if vision is blurred.
How do you protect against nerve agents?
If available, a good way to protect yourself from nerve agents is to wear appropriate chemical protective clothing and respiratory protection. However, protective equipment does not always work against nerve agents.
What are G agents?
Nerve agents GA(tabun), GB (sarin), GD(soman), and VX are manufactured compounds. The G-type agents are clear, colorless, tasteless liquids miscible in water and most organic solvents. GB is odorless and is the most volatile nerve agent. GA has a slightly fruity odor, and GD has a slight camphor-like odor.
What are the 3 phases of the public health emergency preparedness and response capabilities planning model?
Task 1: Identify jurisdictional community recovery priorities.. Task 2: Identify the jurisdictional public health agency role in community recovery. Task 3: Identify recovery services to be provided by the jurisdictional public health agency, partners, and stakeholders.
What is the role of the public health professional in detecting responding to and recovering from a public health emergency?
The role of public health providers is to promote, protect, and improve the health of individuals and communities. After a major disaster, public health workers are often called upon to participate in a coordinated response to save lives and prevent unfavorable outcomes to vulnerable populations.
Which law or regulation requires hospital personnel to be well trained in the incident command system?
Governance. The California Health and Safety Code Division 2.5, Chapter 3, State Administration Section 1797.151 requires EMSA to coordinate medical and hospital disaster preparedness.
How long does it take to remove a toxin from the skin?
Remove all of the patient's clothing and clean the entire skin surface with soap and water. Washing the contaminated area(s) of the skin within 6 hours post-exposure can remove 80-98% of the toxin.
What is T2 mycotoxicosis?
T-2 mycotoxicosis presenting as a non-intentional exposure. Potentially hazardous concentrations of T-2 mycotoxins can occur naturally in moldy grains, cereals, and agricultural products. The control of T-2 mycotoxicosis relies on strict controls on food quality, the proper storage of grains (to include the proper storage of livestock feeds). No specific antidote is available; treatment is supportive. Superactivated charcoal may be given orally if the toxin is swallowed.2 For information on the management of T-2 mycotoxicosis, see:
How is T2 mycotoxin released?
release.2 If T-2 mycotoxicosis is the result of a terrorist act or an intentional or deliberate release, T-2 mycotoxin would most likely have been disseminated via an aerosol. In such a release, the T-2 mycotoxin could adhere to and penetrate the skin, be inhaled, or be ingested; thus exposure from all three routes can occur. High attack rates, dead animals of multiple species (both domestic and non-domestic), along with physical evidence such as yellow, red, green, or other pigmented oily liquids, may suggest mycotoxin exposure. Rapid onset of symptoms within minutes to hours supports a diagnosis of a chemical or toxin attack. In addition, the following clues may also be used to determine if an intentional or deliberate release occurred.6
What is a suspected case?
Suspected: A case in which a potentially exposed person is being evaluated by health-care workers or public health officials for poisoning by a particular chemical agent, but no specific credible threat exists.
