Document Summary
Thermal burns: burns caused by flame, flash fire, scalding, or contact with hot objects (most common). Chemical burns: results form tissue injury and destruction from acids, alkalis, and organic compounds. Alkali burns can be more difficult to manage than acid burns b/c alkaline substances are not neutralized by tissue fluids as readily as are acid substances. Smoke and inhalation injury: damage to the tissues of the respiratory tract that result from the inhalation of hot air or noxious chemicals. Although damage to the respiratory mucosa can occur, it rarely happens b/c the vocal cords and glottis close as a protective mechanism. Smoke injuries are a major predictor of mortality in burn-injured patients, a rapid assessment is critical. Three types of smoke and inhalation injuries: carbon monoxide poisoning, inhalation injury above the glottis, inhalation injury below the glottis. Electrical burns: result of intense heat generated from an eclectic current; direct damage to nerves and vessels causing tissue anoxia and tissue death.
