BACKGROUND
Carbon monoxide (CO) poisoning is one of the most important intoxications in the modern world. This study aimed to identify the characteristics of CO poisoning deaths in Sichuan province in the west of China.
METHODS
Data on fatal non-fire-related carbon monoxide poisoning in Sichuan from 2008 to 2016 were obtained from the Department of Forensic Analytical Toxicology of Sichuan University and were analyzed by the month and year of registration of death, sex, age group, manner of death, source of CO, and location of CO exposure. Comparing with the previous studies carried out in Wuhan and Shanghai to identify the regional differences of CO poisoning in China.
RESULTS
A total of 165 non-fire related CO poisoning cases including 237 victims were recorded. Over 90% of the victims died from accidental poisoning. Non-fire related CO poisoning occurred more frequently in winter months and was most prevalent in individuals aged between 18 and 60 yr old. Showering gas accident and coal or charcoal burning was found to be the major source of CO in accident and in suicide cases, respectively. Furthermore, significant regional differences of CO poisoning have been detected in the manner of death and the source of CO.
CONCLUSION
These findings will be valuable in the targeted prevention of non-fire related CO poisoning in China.
背景
一氧化碳（CO）中毒是现代社会最重要的中毒类型之一。本研究旨在明确中国西部四川省CO中毒死亡的特征。
方法
获取2008年至2016年四川大学法医分析毒理学系有关四川省非火灾相关一氧化碳中毒的死亡数据，并按死亡登记月份和年份、性别、年龄组、死亡方式、CO来源及CO暴露地点进行分析。与此前在武汉和上海开展的研究进行比较，以明确中国CO中毒的地区差异。
结果
共记录了165例非火灾相关CO中毒病例，涉及237名受害者。超过90%的受害者死于意外中毒。非火灾相关CO中毒在冬季更为频发，18至60岁个体最为常见。发现淋浴煤气事故和煤炭或木炭燃烧分别是意外事故和自杀案件中CO的主要来源。此外，在死亡方式和CO来源方面检测到显著的地区差异。
结论
这些发现对于中国针对性预防非火灾相关CO中毒具有重要价值。
