To document the epidemiology and risk factors of acute carbon monoxide (CO) poisoning in the west of Iran and specify potentially presentable characteristics.
Observational study.
Imam Khomeini Hospital of Kermanshah, Iran, from July 2006 to March 2008.
This study was conducted using the records of 143 cases of CO poisoning referred to the only centre for the reference of poisoning cases. Intent, age groups, source of poisoning and clinical presentation were noted and described as frequency.
One-hundred forty two cases (99.3%), were accidental and only one case (0.7%) was suicidal. Mortality was (21.7%, n=31). The highest mortality was found in the age groups of 20-30 years and below 10 years. The greatest frequency happened in autumn and winter. The clinical symptoms and manifestations of CO poisoning included headache (35.3%), nausea (25.4%), vomiting (21%), dyspnea (10.3%), and decrease in level of consciousness (8%). Gas water heaters (35%), room heaters (32%), stoves (24%) and other items (9%) were the principal sources of the individuals' exposure to CO.
CO poisoning is a serious public health problem in west of Iran (Kermanshah). The number of CO poisoning cases was highest in the colder seasons of the year, whereas the majority of the poisoning cases could be prevented.
