Fig 1 Alteration of arterial oxygenation efficiency (PaO2/FiO2) between conventional therapy (dotted line) and early low-dose steroid therapy (solid line). In early low-dose steroid therapy an increase in the PaO2/FiO2 ratio was observed in 10 patients immediately after starting low-dose methylprednisolone treatment. The mean PaO2/FiO2 ratio, which was 188 ± 67 before treatment, increased to 222 ± 87 on day 4, 266 ± 104 on day 5, and 291 ± 73 on day 6 (p < 0.05), and had also significantly increased between days 3 and 4 and between days 5 and 6 (p < 0.05). The median number of days before tapering methylprednisolone was 4.5 (range, 3 to 10 days), and the median number of days before cessation of methylprednisolone or changing to a single oral dose was 9.5 (range, 5 to 19 days). (ARDS = acute respiratory distress syndrome; immed. = immediate postoperative; POD# = postoperative day number; preop. = preoperative.)

Fig 2 Chest image findings at the onset and follow-up after recovery in 2 acute respiratory distress syndrome patients from the early low-dose steroid therapy group. (A–C) Chest roentgenogram image and computed tomographic (CT) scans of a 65-year-old man who underwent right lower lobectomy and wedge resection of the left and right upper lobes under bilateral thoracotomies. (A) Chest infiltration was initiated 3 days postoperatively. (B) Acute respiratory distress syndrome was confirmed on day 4 and chest CT was performed. (C) Follow-up chest CT after 1 month revealed complete resolution of chest infiltration. (D–F) Chest roentgenogram image and CT scans of a 67-year-old man who underwent left pneumonectomy for lung cancer. (D) Chest infiltration was initiated 2 days postoperatively. (E) Acute respiratory distress syndrome was confirmed on day 3. (F) Follow-up CT after 1 month revealed complete resolution of chest infiltration.
