Abstract:
PURPOSE: Humans have been poisoned by carbon monoxide(CO) ever since they first discovered hydrocarbon fuels, incomplete combustion of which is the usual cause of the poisoning. The early symptoms of CO poisoning are usually variable, vague, and nonspecific, which can lead to thewrong diagnosis. METHODS: This study reviewed 42 cases of CO poisoning that occurred from January 1, 1995, to December 31, 2001. The study was conducted retrospectively to discover the patients' age distribution, sex ratio, the time of exposure, the site of exposure, and the cause of exposure. RESULTS: The ratio of males to females was 1:2.9. Age distribution was broad: 8 of below 18 years old, 9 between 19 and 39 years old, 9 between 40 and 59 years old, and 16 over 60 years old. In terms of seasonal difference, 28 cases happened during the heating season whereas 13 cases occurred in non-heating season. Twenty-three (23) cases happened in the early morning, 12 during the day time, 3 in the evening, and 4 during night. Of the exposures, 27 occurred in the home, 8 in the workplace, and 7 in hotels. Faulty heating systems caused 31 exposures, fires 2 exposures, stoves 4 exposures, and generators 5 exposures. Fifteen patients were repoisoned by CO, and of these, 9 patients had been misdiagnosed in the past exposures. CONCLUSION: The sources of CO are variable, so humans are poisoned often. It is common to see that the victim - sometimes even several members of the same family - had already visited a doctor with symptoms of CO toxicity before the severe exposures or death. The doctor strongly needs to pursue the possibility of victim poisoning when patients have recurrent or vague symptoms similar to those associated with CO exposure.
