ABSTRACT

It is very difficult to recognize carbon monoxide (CO) poisoning since CO is a colorless, odorless, tasteless, and non-irritating gas. Statistical data indicates that CO poisoning and related deaths in Turkey are mostly caused by coal burning stoves used for heating. There are a wide variety of clinical features, ranging from nausea, headache and dizziness to coma. In this study, we present a case of poisoning in a patient who attended the emergency department twice with the same clinical signs. The patient was considered to have CO poisoning, had no anamnesis of exposure, and all family members were affected without being aware of it.
