Hydrogen cyanide is an extremely poisonous, colorless, flammable liquid used in multiple industries and includes rubber, plastic, and household paints. Exposure Exposure ABCDE Assessment to cyanide can occur via inhalation, dermal contact, or intestinal ingestion. Cyanide poisoning is a common complication of closed-space fires since cyanide is a byproduct of plastics combustion. Symptoms develop within seconds to minutes and involve cardiovascular, respiratory, and neurological changes. Management includes sodium Sodium A member of the alkali group of metals. It has the atomic symbol na, atomic number 11, and atomic weight 23. Hyponatremia thiosulfate, nitrites, and hydroxocobalamin. If not recognized and treated promptly, cyanide poisoning is frequently lethal.

Cyanide is a highly lethal mitochondrial toxin causing death within minutes to hours of exposure Exposure ABCDE Assessment.
Symptoms develop within seconds to minutes.
Acute cyanide poisoning:

cerebral edema
Cerebral edema
Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries. An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive hydrocephalus).

Brain
The part of central nervous system that is contained within the skull (cranium). Arising from the neural tube, the embryonic brain is comprised of three major parts including prosencephalon (the forebrain); mesencephalon (the midbrain); and rhombencephalon (the hindbrain). The developed brain consists of cerebrum; cerebellum; and other structures in the brain stem.
