急诊SARS患者初诊时血常规特点分析

Analysis on blood routine characteristic of severe acute respiratory syndrome patients in emergency department

目的 :探讨严重急性呼吸综合征 (SARS)与急性呼吸道感染 (ARI)患者发病初期血常规特点 ,为早期鉴别诊断提供参考。方法 :采集急诊 SARS与 ARI患者初诊时的血常规检验指标 ,建立数据库 ,运用描述性分析及推断性分析 (χ2检验和 u检验 )方法 ,对两组患者的血常规指标进行对照分析。结果 :早期 SARS患者的白细胞计数、淋巴细胞计数、中性粒细胞计数、血小板计数、血小板容积比均低于 ARI患者 (P均 <0 .0 5 ) ;两组的中性粒细胞比例与淋巴细胞比例差异无显著性 (P均 >0 .0 5 )。结论 :血常规检查是急诊初诊时临床诊断 SARS的重要依据之一。

Objective: To investigate the different blood routine characteristics between severe acute respiratory syndrome (SARS) and acute respiratory infection (ARI) patients, and provide reference to earlier differential diagnosis. Methods: Set up a database of blood routine examination information of SARS and ARI at the time they first coming to emergency department. Then using descriptive statistics and deductive statistics (U test and Chisquare test) to analyze the data. Results: Leukocyte count, lymphocyte count, neutrocyte count, platelet count and platelet bulk ratio of SARS were lower than those of ARI in earlier period (all P<0.05). But neutrocyte proportion and lymphocyte proportion in both groups had not valuable difference (both P>0.05). Conclusion: Blood routine examination is one of the important evidences for SARS' clinical preliminary diagnosis in emergency department.
