Abstract

Carbon monoxide (CO) poisoning still represents a frequent and severe casualty in France. Aside the well-known effect of CO on hemoglobin, the role of CO binding to other hemoproteins like myoglobin and cytochrome a3 have been more recently recognized. Moreover, in addition to these hypoxic injuries, the reoxygenation phase may itself induce toxic effects by a mechanism close to the ischemia-reperfusion phenomenon. Clinical manifestations include neurologic disturbances, cardiac arrythmia, respiratory and circulatory failures which usually disappear with removal from toxic atmosphere and administration of oxygen. However, long term neurologic manifestations may occur and lead to important functional impairment and disability. Hyperbaric oxygen in actually the treatment of choice to avoid the occurrence of delayed sequelae. HBO is advocated in every patient who remains comatose on hospital admission, who had lost consciousness during toxic exposure or with persisting neurologic abnormalities. CO poisoned pregnant women should also undergo HBO. Well designed prevention programs are urgently needed in our country to decrease the incidence and the consequences of CO poisoning.
