Abstract

An eighteen year-old female visited the ER in our hospital with fever of 38.5˚C for 2 days. She also had cough, myalgia, and dyspnea. Chest PA and lung HRCT showed mild pulmonary edema at both hilar areas. However, she had severe hypoxia (PaO2; 58 mmHg in room air). RT-PCR for H1N1 influenza/A of pharyngeal swab was positive. Tamiflu (150 mg/d) with broad-spectrum antibiotics was prescribed. Two days later, her dyspnea aggravated and chest PA showed diffuse bilateral infiltration. PaO2 dropped to 70 mmHg (O2 10 L/min by face mask with reservoir bag). She was transferred to the MICU and the Tamiflu dose was doubled (300 mg/day). Mechanical ventilator was set aside to prepare respiratory failure. Fortunately, her symptoms and oxygenation improved and she was discharged with full recovery. Although, most cases of ARDS require mechanical ventilatory support, early and adequate dose of Tamiflu may avoid it in the case of ARDS developed by H1N1 influenza/A.
