Abstract
We analysed 81 patients with asthmatic attack in the outdoor school during the past two years. The incidence of asthmatic attack was 24.3% in all patients. The predilection seasons of asthmatic attack were autumn and spring. The duration from asthmatic attack to medical examination was long: more than 10 hours: 40%. Six patients were hospitalized and one of them with underlying disease died. In the outdoor school it is necessary to take adequate prophylactic measures to prevent asthmatic attack, to consult a doctor at one's earliest convenience and to bring a letter of introduction.
