Exposure to the toxic gases carbon monoxide and nitrogen dioxide (NO2) in indoor ice arenas occasionally occurs and may result in severe symptoms. The gases are produced by ice resurfacing machines operating on hydrocarbons, and in certain conditions toxic levels accumulate. The damage to lung tissues caused by NO2 may not be evident until after a latency time of 1/2-2 days. The role of corticosteroids in the treatment is controversial, but there are clinical experiences as well as experimental data supporting their use. We report two cases of toxic pneumonitis, with delayed onset, due to NO2 exposure during an ice hockey game in an indoor arena. Signs and symptoms were cough, dyspnoea, haemoptysis, hypoxaemia and reduced peak expiratory flow. Chest radiographs showed parenchymatous infiltrative lesions and alveolar consolidation. Both patients were treated with high doses of corticosteroids by inhalation and orally or intravenously. Their condition rapidly improved and pulmonary function was restored.

On February 23, 1992, the Wisconsin Department of Health and Social Services (DHSS) was notified that 11 students from two high schools had been treated in two emergency rooms for acute respiratory symptoms (ARS) (i.e., cough, hemoptysis, chest pain, and dyspnea); two students were hospitalized. All of the students had participated in an indoor ice hockey tournament the previous night.
