Carbon monoxide (CO) is a colorless, odorless, tasteless, and poisonous gas, which is why it is sometimes referred to as the “invisible killer.” Carbon monoxide poisoning is a common, industrial hazard, but many people are injured or killed by the effects of carbon monoxide poisoning at home and on vacation while in hotels, garages, cars, and boats. Everyone is at risk for carbon monoxide poisoning, and, unfortunately, severe damage – and even death – can occur before you even realize what is happening.
Cerebral edema (swelling of the brain) is also a common result of severe carbon monoxide poisoning. This life-threatening condition entails the destruction of brain cells by compressing them into themselves within the cranial compartment. Drugs that are normally used for the treatment of cerebral edema, like Dexamethasone and Mannitol, do not seem to be of assistance in the treatment of CO induced cerebral edema. Studies have shown that cerebral edema caused by CO poisoning can cause delayed neurological problems that involve the “higher” or cognitive functions, and may cause a Parkinsonian-like brain syndrome.
