An increased anion gap metabolic acidosis is expected in patients with cyanide poisoning. Also, consider obtaining acetaminophen and salicylate levels to rule out co-ingestions. All patients presenting from a structural fire are to be presumed to have cyanide toxicity.
Plasma lactate also may be obtained, and a level greater than eight mmol/L is 94% sensitive and 70% specific for significant cyanide toxicity.
Labs that are pertinent to the initial evaluation in a patient with cyanide poisoning are complete blood count, electrolytes, urinalysis, urine tox screen, arterial blood gas, carboxyhemoglobin level (if in a fire), chest x-ray, and EKG. Patients with cyanide poisoning will not be cyanotic but will have a cherry red color due to excess oxygen in the bloodstream.
#Antidote to cyanide skin
It is important to note that a patient's skin can be a normal or slightly ashen appearance despite tissue hypoxia. Hypotension and bradycardia are common in cyanide poisoning. Early respiratory and cardiovascular findings include tachypnea and tachycardia, while late findings include apnea, hypotension, and cardiac arrhythmia. These are due to tissue hypoxia, and seizures and coma can develop as it progresses to an altered level of consciousness. Some early central nervous system findings are headache, dizziness, confusion, and mydriasis.
The clinical manifestations can be divided into early and late categories. If the hydrogen cyanide was inhaled, the victim might detect a bitter, almond odor, which is discernible by approximately 60% of the population. The patient can present with symptoms as quickly as one minute after inhalation and within a few minutes of cyanide ingestion.
