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。
Objective To study the epidemiological characteristics of non-occupational carbon monoxide poisoning in Hefei and provide a scientific basis for establishing an active monitoring mechanism of ametrine-free carbon monoxide poisoning. Methods Based on the “contingency plan for non-occupational carbon monoxide poisoning” to carry out monitoring of non-occupational carbon monoxide poisoning. Results The non-occupational sulfur monoxide poisoning generally increased from the end of November to the end of January, followed by the concentration of cases from early January to early February in the following year (P <0.01). The main cause of the incident to coal-fired heating, poor indoor ventilation, leading to the accumulation of carbon monoxide. The difference in poisoning was not significant in all age groups. Female was slightly more than male in gender. The cases mainly concentrated in urban areas (P <0.01). Conclusion To strengthen the monitoring and reporting on non-occupational carbon monoxide poisoning and find out the early warning of the possible non-occupational carbon monoxide poisoning and ensure the public’s health and safety.
