Nitrogen dioxide (NO₂) is a toxic gas, a product of combustion in malfunctioning ice-resurfacing machines. NO₂ poisoning is rare but potentially lethal. The authors report a case of mass NO₂ poisoning involving 15 amateur ice hockey players in the Czech Republic. All players were treated in the Department of Respiratory Diseases at Brno University Hospital in November 2010 - three as inpatients because they developed pneumonitis. All patients were followed-up until November 2011. Complete recovery in all but one patient was achieved by December 2010. None of the 15 patients developed asthma-like disease or chronic cough. Corticosteroids appeared to be useful in treatment. Electric-powered ice-resurfacing machines are preferable in indoor ice skating arenas.
二氧化氮（NO₂）是一种有毒气体，是故障冰面修整机燃烧的产物。NO₂中毒很少见，但有潜在致命性。作者报告了一起涉及 15 名捷克业余冰球运动员的大规模 NO₂中毒事件。所有运动员均于 2010 年 11 月在布尔诺大学医院呼吸疾病科接受治疗 - 3 名患者因出现肺炎而住院。所有患者均随访至 2011 年 11 月。到 2010 年 12 月，除 1 名患者外，所有患者均完全康复。15 名患者中均未出现哮喘样疾病或慢性咳嗽。皮质类固醇似乎对治疗有用。室内滑冰场宜使用电力驱动的冰面修整机。
