Between August 2009 and March 2010, 169 children with influenza A (H1N1)pdm infection were hospitalized in this area. The rate of hospitalization was 185 per 100,000 children aged 0-14 years. At the time of admission, 82 patients (49 %)were diagnosed with pneumonia or bronchitis, and 31 patients (18%)with bronchial asthma. Oxygen saturation (SpO2)was measured in 160 patients by using a pulse oximeter ; 29 patients (18%)were found to have severe hypoxemia, defined by SpO2<90%, and 8 of them were immediately transferred to the pediatric intensive care unit of Nagano Children’s Hospital. Oxygen was supplied and steroids were administered to treat hypoxemia in the case of 81(48%)and 63 patients (37%), respectively. Five patients (3%) required mechanical ventilation support, but no patients died. All patients except 4 (98%) were treated with either oseltamivir or zanamivir. Early detection of severe hypoxemia is important in treating patients with influenza A (H1N1) pdm infection.
