Maintain the airway and assess for airway burns, stridor, or airway edema and if indicated, perform intubation early (recommendation to avoid supraglottic airways cricothryoidotomy may be required in rarer severe cases b. This medication should be repeated at this dose with unlimited frequency for ongoing distress 4. Treat topical chemical burns [see appropriate Toxins and Environmental section guideline(s)] 10. In severe respiratory irritation, in particular hydrogen sulfide, with altered mental status and no improvement with removal from the toxic environment, administer oxygen (humidified if available) as appropriate with a target of achieving 94-98% saturation consider consultation for transfer to a hyperbaric oxygen therapy Medication Administration 1. Generally, speaking to patients with exposure to highly soluble airway/respiratory irritants you will find that they have self-extricated due to the warning properties such as the smell, rapidity of onset of irritation, and other symptoms 2. Airway respiratory irritants can exacerbate underlying reactive airway diseases. As patients may be off gassing (particularly hydrogen sulfide and hydrogen cyanide) in the back of the transport vehicle, it is recommended to have adequate ventilation of the patient compartment 3. Removal from the toxic environment, oxygen (humidified if available), general supportive therapy, bronchodilators, respiratory support, and time are core elements of care as there are no specific antidotes for any of these inhaled agents with the exception of heavy metals that may be chelated by physicians after agent identification 4. Hydrogen sulfide causes the cells responsible for the sense of smell to be stunned into inaction and therefore with a very short exposure will shut down and the exposed victim will not perceive the smell yet the victim continues to absorb the gas as it is still present 5. Household bathroom, kitchen, and oven cleaners when mixed can generate a varied of these airway respiratory irritants (ammonia, chloramine, and chlorine gas releases are particularly common). A very common exposure is to chloramine, a gas liberated when bleach (hypochlorite) and ammonia are combined. Chloramine then hydrolyzes in the distal airways and alveoli to ammonia and hypochlorous acid 7. Some inhalants can cause the heart to beat rapidly and erratically and cause cardiac arrest b. This syndrome most often is associated with abuse of butane, propane and effects of the chemicals in the aerosols Pertinent Assessment Findings 1. Patient may describe a specific odor (chlorine swimming pool smell, ammonia smell, fresh mowed hay smell [phosgene]) which may be helpful but should not be relied upon as the human nose is a poor discriminator of scent 2. Baydala L, Canadian Paediatric Society, First Nations, Inuit and Metis Health Committee. Effects of infusion of human methemoglobin solution following hydrogen sulfide poisoning. Exaggerated responses to chlorine inhalation among persons with nonspecific airway hyperreactivity. Occupationally related hydrogen sulfide deaths in the United States from 1984 to 1994. Acute accidental exposure to chlorine gas in the Southeast of Turkey: a study of 106 cases. High-dose hydroxocobalamin administered after H2S exposure counteracts sulfide poisoning induced cardiac depression in sheep. Exposure to identifiable agents that are not intended to cause significant injury or fatality Exclusion Criteria 1. Exposure to chlorine, phosgene, ammonia or other agents that are intended to cause significant injury or fatality 2. Move affected individuals from contaminated environment into fresh air if possible 2. Irrigation with water or saline may facilitate resolution of symptoms and is recommended for decontamination of dermal and ocular exposure 5. Exposed individuals who are persistently symptomatic warrant further evaluation and treatment per local standards Patient Safety Considerations 1. Toxicity is related to duration of exposure and concentration of agent used (exposure in non-ventilated space) 2.
