Chest X-ray on day 1 shows bilateral basal consolidation with periphearal ground-glass opacity. Chest X-ray on day 2 shows bilateral pulmonary infiltrate mainly in hilar region. Chest X-ray on day 20 shows bilateral diffuse pulmonary infiltraes with air bronchogram. Chest X-ray on day 23 shows improved bilateral lung opacity (mainly in the right lobe of lungs). Chest X-ray on day 27 (extracorporeal membrane oxygenation removed).acute respiratory syndrome coronavirus 2 nucleic acid. He required veno-venous extracorporeal membrane oxygenation (V-V ECMO) to sustain his oxygenation. However, his respiratory failure did not improve for 20 days. On day 20 of admis-sion, we started to use i.v. steroid therapy. On day 23, lung opacity on the chest X-ray cleared and removed ECMO on day 27. We are successfully tapering steroids without serious adverse events, and he was removed from the ventilator on day 51 (Figure 3). (from clinical research to basic one)It has been 15 years since I was assigned to this hospital, and I have 62 colleagues at Urayasu Hospital. They have all acquired various medical specialties, and some are emergency medicine specialists. Eighteen have earned doctoral degrees in medicine and many have studied abroad at Harvard University and the Feinstein Institute in New York.-Clinical research-Our research areas are diverse (Table 3). In clin-ical research, studies on the emergency room included triage by rapid lactate measurement, rela-tionship with dizziness and heart rate variability, The first case of the efficacy of steroid treatment for COVID-19.After my transfer, I also experienced many disasters and incidents, including the Great East Japan Earthquake, and the coronavirus disease (COVID-19) pandemic, with which we are still battling. We reported the first case of the efficacy of steroid treatment for COVID-19 (3). A 67-year old man was transported to our hospital due to impaired consciousness and respiratory failure. After admission, tracheal aspirate of the patient was harvested, and it tested positive for severe Our various research areas
