贫血是一个综合征,可见于血液病及其他各系统疾病,后者称为继发性贫血,比较常见,如张之南报告786例贫血中,继发性贫血者639例(81.2%)。继发性贫血一般有原发疾病表现,不难诊断。但以贫血为首要表现的病例,如不仔细探查,则易遗漏原发病而延误诊治。我院1979～1983年5年中,以贫血为首要表现,以“贫血待查”收住院的共256例,最终诊断为继发性贫血的104例(40.6%),其病因见附表。本组贫血诊断按世界卫生组织提出的6个月～6岁,Hb<11克%(g/dl);6岁～14岁,Hb<12g/dl为标准。贫血程度以Hb 11(12)～9.1g/dl为轻度;9～6.1 g/d1为中度;6～3.1g/dl为重度;<3 g/dl为极重度。现将104例中确诊过程比较曲折的或带有普遍性的6 Anemia is a syndrome seen in blood diseases and other systemic diseases, the latter known as secondary anemia, more common, such as Zhang Zhinan reported 786 cases of anemia, secondary anemia in 639 cases (81.2%). Secondary anemia generally have primary disease performance, not difficult to diagnose. However, anemia as the primary manifestation of cases, if not carefully probed, it is easy to miss the primary disease and delay diagnosis and treatment. Our hospital from 1979 to 1983, 5 years, with anemia as the primary manifestation, “awaiting investigation,” admitted to the hospital a total of 256 cases, the final diagnosis of secondary anemia in 104 cases (40.6%), the etiology of the schedule. The diagnosis of anemia in this group according to the World Health Organization 6 months to 6 years old, Hb <11 g% (g / dl); 6 years old to 14 years old, Hb <12g / dl as the standard. Anemia in Hb 11 (12) ~ 9.1g / dl is mild; 9 ~ 6.1g / d1 is moderate; 6 ~ 3.1g / dl is severe; <3g / dl is extremely severe. Now 104 cases of the diagnosis of more complicated or with the prevalence of 6
