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
Objective To explore the characteristics of blood in patients with SARS and to grasp their changes in order to facilitate SARS patients, especially severe SARS early diagnosis. Methods A total of 46 cases of SARS patients were collected and divided into general group and severe group. The total number of leucocytes, neutral classification, lymphocyte percentage and platelet count were compared between the two groups. Results Compared with the normal SARS group, there were significant differences in all the blood parameters between the severe SARS group and the normal SARS group (P <0.01). Leukocyte, neutrophil percentage, total platelet count increased significantly, the percentage of lymphocytes decreased significantly. Conclusion Severe SARS patients often accompanied by a significant increase in the total number of leukocytes and neutrophil count, lymphocyte count decreased, usually prompted double infection, the immune function decreased further
