Abstract:
Objective To investigate and know the clinical features and the pathogenic pattern of acute carbon monoxide poisoning ( ACOP) in the northeast region of Beijing. Methods A total of 496 cases of ACOP admitted to the Emergency Department and Hyperbaric Oxygen Department of the Beijing Huairou Hospital from January 2015 to December 2017 were collected for the study. Statistical analysis was made in accordance with gender, age, occupational characteristics, and causes and seriousness of poisoning. Results Of the 496 cases of ACOP, 459 were mild and moderate cases, and 37 were severe cases, and 3 cases died at the time of admission. The patients were mostly within the age of 50 -69, and there were 211 cases that occurred mass poisoning involving more than 2 people. The top 3 causes of poisoning were: coal stove heating, kang heating and charcoal burning. The farmers and the floating population were the ones mostly affected, accounting for 68. 7％, and the time of seeking medical care was from 7:00 to 13:00. All the patients after admission were given routine oxygen inhalation, symptomatic drugs and HBO treatment in accordance with the severity of the disorder. All the patients with mild and moderate poisoning were cured without any sequelae, and of all the severe cases, 13 displayed delayed encephalopathy, accounting for 2. 6％ of the total cases. Conclusion ACOP occurred quite occasionally in winter and spring in the northeast of Beijing, The areas affected were mostly mountainous and rural regions and those adjacent ones between urban and rural areas. The farmers and the floating population constituted the majority of the affected population. Mass poisoning involving more than 2 people was the situation that should not be ignored, Timely and effective first-aid symptomatic treatment, as well as standardized HBO therapy could effectively reduce sequelae in the affected patients.
