Therapeutic strategy for severe COVID-19 pneumonia from clinical experience

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It was first identified in December 2019 in Wuhan, China, and has resulted in global pandemic. There is currently no effective therapeutic strategy for the management of mechanical ventilation or antiviral drugs for the treatment of this disease. As such, the development of a therapeutic strategy is urgently needed and should be established as soon as possible. In this case series, a therapeutic strategy was initially developed based on previous treatment methods used for the treatment of SARS and MERS in the absence of treatment options for COVID-19 due to a lack of information. During the search for a potential treatment, clinical findings were obtained from patients with severe COVID-19, and one therapeutic strategy was established. This therapeutic strategy was then applied to severe COVID-19 patients. In addition, we can require some interesting clinical features and characteristics of COVID-19 from blood analysis and physical findings. Here, we reported on the clinical features and characteristics of a therapeutic strategy for the treatment of severe COVID-19 pneumonia at our institution.
