To determine carboxyhemoglobin levels and to investigate carbon monoxide poisoning risk in children.
We determine carboxyhemoglobin blood levels by cooximetry in 65 children, between 15 days and 15 years attended in a pediatric emergency section. We analyze carbon monoxide risk factors (type of heating and smokers in the family).
Mean carboxyhemoglobin levels in 59 children without acute intoxication was 0.5 +/- 0.87% (range 0-3.8%). There are no significant differences with respect to age and sex. Children with wood or coal heating (0.88 +/- 1.34%) and gas heating (0.58 +/- 0.97%) have carboxyhemoglobin levels higher than children with electric heating (0.28 +/- 0.4%) but differences were no statistically significant. Four patients have carboxyhemoglobin levels > 2%, two with coal or wood hating and two with gas heating. Children with smokers in the family have carboxyhemoglobin levels higher than the rest of children (0.65 +/- 1.05% versus 0.34 +/- 0.45%) without statistical significance. The four children with carboxyhemoglobin levels > 2% live with smokers. Six children suffered carbon monoxide poisoning with carboxyhemoglobin levels between 20.6 and 36.6%.
Mean carboxyhemoglobin levels in children are low. There are carbon monoxide poisoning risk factors (wood, coal or gas heating at home, and smokers in the family) in a high percentage of the children, although they did not show statistical significance.
测定儿童碳氧血红蛋白水平并调查一氧化碳中毒风险。
我们采用多波长分光光度法测定了65名年龄在15天至15岁之间、在儿科急诊科就诊的儿童的血液碳氧血红蛋白水平。我们分析了一氧化碳风险因素（家庭供暖类型和家庭成员是否吸烟）。
59名无急性中毒的儿童的平均碳氧血红蛋白水平为0.5±0.87%（范围为0 - 3.8%）。在年龄和性别方面无显著差异。使用木材或煤炭供暖的儿童（0.88±1.34%）和使用燃气供暖的儿童（0.58±0.97%）的碳氧血红蛋白水平高于使用电供暖的儿童（0.28±0.4%），但差异无统计学意义。4名患者的碳氧血红蛋白水平>2%，其中2名使用煤炭或木材供暖，2名使用燃气供暖。家中有吸烟者的儿童的碳氧血红蛋白水平高于其他儿童（0.65±1.05%对0.34±0.45%），但无统计学意义。碳氧血红蛋白水平>2%的4名儿童与吸烟者生活在一起。6名儿童发生一氧化碳中毒，碳氧血红蛋白水平在20.6%至36.6%之间。
儿童的平均碳氧血红蛋白水平较低。尽管未显示出统计学意义，但很大比例的儿童存在一氧化碳中毒风险因素（家中使用木材、煤炭或燃气供暖以及家庭成员吸烟）。
