目的　探讨SARS患者血象特点 ,掌握其变化规律 ,以利于SARS患者 ,尤其是重症SARS的早期诊断。方法　收集 4 6例留院观察的SARS患者 ,分为普通组与重症组 ,对两组白细胞总数、中性分类、淋巴细胞百分比、血小板计数、从发病到留院观察的时间进行比较。结果　重症SARS组与普通SARS组相比 ,血象各个指标均有显著性差异 (P <0 .0 0 1)。白细胞、中性粒细胞百分比、血小板总数显著升高 ,淋巴细胞百分比显著下降。结论　重症SARS患者常伴有白细胞总数及中性粒细胞计数显著升高、淋巴细胞计数降低 ,通常提示合并二重感染 ,机体免疫功能进一步下降

Analysis on hemogram of severe SARS patients

Objective To study hemogram characters of SARS patients and supply valuable data for early diagnosis of SARS,particularly severe SARS patients.Methods Information of 46 cases SARS patients were collected in Anzhen hospital from April 4 th to May 9th.The amount of leucocyte,leucocyte percentage and percentage of lymphoid cell,blood platelet count were compared between common SARS and severe SARS.Results There is a remarkable difference of all parameters of hemogram between these two groups ( P <0.001),Compared with common SARS,the WBC dount,leucocyte percentage,platelet count were significantly elevated in severe SARS group while lymphocyte percentage was significantly decreased.Conclusions Severe SARS patients always have elevated WBC count and leucocyte percentage and decreased lymphocyte percentage which means the secondary infections.
