我们已认识到慢性肺心病Ⅱ型呼衰患者可出现代偿性红细胞增多,血色素增加,同时也注意到有些病人血色素不高,甚至贫血。但关于这种病人的骨髓象资料甚少,为探讨肺心病Ⅱ型呼衰病人造血系统方面的变化,我们近年来对38例肺心病Ⅱ型呼衰患者进行骨髓象及血粘度等观察,现报告如下。 We have recognized that chronic pulmonary heart disease type II respiratory failure patients may appear compensatory polycythemia, increased hemoglobin, but also noticed that some patients hemoglobin is not high, and even anemia. However, there is little information about this patient’s bone marrow. In order to explore the changes in the hematopoietic system of patients with chronic heart failure type Ⅱ, we observed the bone marrow and blood viscosity in 38 patients with pulmonary heart disease type Ⅱ respiratory failure in recent years. The report is as follows.
