合肥市2006—2009年冬春季节一氧化碳中毒事件监测分析

Monitoring and Analysis of Carbon Monoxide Poisoning Cases in Winter and Spring during 2006—2009 in Hefei City

目的研究合肥市非职业性一氧化碳中毒的流行病学特征,为建立非职业性一氧化碳中毒的主动监测机制提供科学依据。方法依据《非职业性一氧化碳中毒事件应急预案》开展非职业性一氧化碳中毒事件监测。结果非职业性一氧化硫中毒事件总体上从11月下旬开始增多,次年的1月上旬到2月上旬病例较集中(P<0.01)。事件原因多以燃煤取暖为主,室内通风不良,导致一氧化碳的蓄积。中毒在各年龄段差距不大,性别上女性略多于男性,病例主要集中在市区(P<0.01)。结论加强非职业性一氧化碳中毒监测、报告工作,发现对可能引发非职业性一氧化碳中毒事件的情况及时预警,保障公众的身体健康和生命安全。

[Objectives]To study the epidemiological characteristics of non-occupational carbon monoxide poisoning in Hefei city,provide scientific basis for the establishment of active monitoring mechanism for non-occupational carbon monoxide poisoning.[Methods]According to Emergency Plan against Non-occupational Carbon Monoxide Poisoning,the monitoring of non-occupational carbon monoxide poisoning cases was performed.[Results]The cases of non-occupational carbon monoxide poisoning increased since late November,and majority of cases occurred from beginning of January to beginning of February in the next year （P0.01）.The main cause was coal heating,bad indoor ventilation,resulting in the accumulation of carbon monoxide.There was not obvious difference among different age groups,female cases were slightly more than male cases,and most of the cases were found in urban area （P0.01）.[Conclusion]In order to ensure the public health and life safety,monitoring and reporting of non-occupational carbon monoxide poisoning should be strengthened,and early warning should be performed timely when risk factors existed.
