Abstract:
Objective To analyze the epidemiological features of acute carbon monoxide poisoning (ACOP) in children induced by coal burning for home-heating, so as to provide evidence for ACOP prevention and control.Methods A retrospective analysis was made on the medical data of gender , age, dwelling place, poisoning time, intoxication of family members , implementation time of hyperbaric oxygen ( HBO) therapy in child patients with ACOP admitted to the Department of HBO of Tianjin Children's Hospital from June 1, 2012 to May 31, 2017 due to coal burning for home-heating in Tianjin area from 2012 to 2017.Results In the past 5 years, a total of 381 patients with ACOP were admitted for treatment , including 322 patients intoxicated (84.51％)owing to burning coal for home-heating.Of the 322 patients, 181 were boys (56.21％) and 141 were girls (43.79％).Age ranged from 22 days to 15 years old, with an average age of 4.2 ±3.3 years.And of the 322 patients, 73 were younger than 1 year old (22.67％), 85 were in the age of 1-3 years (26.40％), 91 were in the age of 3-6 years (28.26％), and 73 were over 6 years old (22.67％).As to the area of distribution of ACOP, 37 cases were in 6 main municipal districts of Tianjin , accounting for (11.49％), 166 cases were in the suburban , accounting for 51.55％and 119 cases were in exurban of the city , accounting for 36.96％, with an annual average incidence of 64.4 cases.Most cases ( 281, 87.27％) occurred in the centralized heating period, i.e.from Nov 15 to Mar 15 nest year, and relatively few cases (41, 12.73％) occurred beyond the heating period .Beyond the heating period , the percentage of ACOP patients younger than 1 year was 29.27％(12/41), and statistical significance could be noted when comparisons were made (P=0.004).There were 280 ACOP patients (86.96％) who had ACOP at night (86.96％), and there were 272 patients (84.47％) whose family members also had ACOP , with a total 489 family members having ACOP . One hundred and forty-one patients (43.79％) received HBO therapy , 6 hours after the onset of symptoms of carbon monoxide poisoning , and on the average , they had 6.1 sessions of HBO therapy .Conclusion In the highly prevalent city areas , during the winter season and among special population of the city , propaganda and early warning concerning knowledge of carbon monoxide poisoning should be made , so as reduce the rate of ACOP.
