ABSTRACT
Number of chronic obstructive pulmonary disease (COPD) patients tend to increase in middle and older aged people. They have shown a certain degree of improvement with various Western medicine treatments including smoking cessation guidance, rehabilitation, home oxygen therapy, inhalation therapy and so on. However, it is a clinical problem that some elderly people have acute exacerbations frequently due to infectious diseases and have poor prognoses. This time, we experienced an elderly COPD patient with type II respiratory failure. He was repeatedly hospitalized and needed treatment with a ventilator temporarily. We conducted Kampo medical examination on him, and diagnosed that he had cold state in the lungs. So, we administered ryokankyomishingeninto to him. As a result, he recovered dramatically, and he was never hospitalized again due to respiratory failure for a long time. It is suggested that ryokankyomishingeninto may be effective for some COPD patients who have cold state in the lungs.
