AbstractDuring the years 1986 to 1990, an increasing number of cases of acute carbon monoxide (CO) poisoning were encountered in the Emergency Department Hacettepe University Hospital in Ankara, Turkey. Between January 1 and March 31, 1991, all the patients presenting with complaints compatible with CO poisoning were evaluated; the diagnosis was confirmed in 55 of the 5795 people who attended the Emergency Department during this period. In all cases the source of CO intoxication was determined. Among these patients, nausea or vomiting and headaches were the most common complaints (occurring in 100% and 85%, respectively). At least transient impairment of alertness was observed in 29% of cases. The carboxyhaemoglobin levels ranged from 3.80 to 48.1% (median 14.2%). Two comatose patients who developed a non-cardiogenic pulmonary oedema required mechanical ventilation. One of them was discharged from the hospital with mild cerebral disability. Another patient developed an acute myocardial infarction. In all the cases in this series, the source of CO poisoning was identified as improper combustion of recently marketed steam coal in inadequately ventilated bucket stoves.
