ACUTE EXPOSURE INFORMATION
- Sodium cyanide exposure may produce death within minutes. Signs and symptoms following non-lethal, subacute, or chronic exposure may include syncope, weight loss, headache, dizziness, nausea, vomiting, palpitations, confusion, deep inspiratory gasps followed by hyperpnea, hyperventilation, anxiety, and vertigo.
- Cyanosis is generally a late finding and usually does not occur until circulatory collapse and apnea are evident; particularly at the premorbid stage of cyanide toxicity. Initially the patient may experience flushing, tachycardia, tachypnea, headache, and dizziness. This may progress to agitation, stupor, coma, apnea, seizures, metabolic acidosis, pulmonary edema, bradycardia, hypotension, and death.
- Sodium cyanide exposure may produce death within minutes. IMMEDIATELY BEGIN ADMINISTERING 100% OXYGEN. OBTAIN THE CYANIDE ANTIDOTE KIT AND PREPARE IT FOR USE. Non-lethal, subacute, or chronic exposure may produce headache, dizziness, nausea, vomiting, palpitations, confusion, deep inspiratory gasps followed by hyperpnea, hyperventilation, anxiety, and vertigo. Severe signs of hypoxia in the absence of cyanosis suggest cyanide poisoning. Patients have reportedly survived potentially lethal ingestions with only supportive care. The absence of a rapidly deteriorating course does not exclude cyanide poisoning.
