Second-Hand Smoking in Children: How Extensive Is It?

摘要: Sources of carbon monoxide include wood/gas-burning stoves, oil/gas heaters, motor vehicles and tobacco smoking, likely the most relevant source. Secondhand smoking can contribute to adverse outcomes in pediatric anesthesia. The prevalence of increased preoperative carboxyhemoglobin (COHb) in children is unknown. This prospective study with a noninvasive COHb monitor seeks to determine preoperative COHb levels in children and to assess a possible link between elevated COHb values and parental smoking as well as additional environmental factors. Interim results are presented.
