目的 探讨成人急性腹泻相关临床参数的关系.方法 回顾性调查2018年4月至10月应急总医院肠道门诊649例留取大便标本的急性腹泻患者,收集性别、年龄、发病至就诊时间、最高体温、主要症状、流行病学史、血常规、C反应蛋白和大便常规,统计分析急性腹泻的相关临床因素.结果 共调查70例临床诊断急性细菌性痢疾患者、180例临床诊断感染性腹泻患者和399例腹泻待查患者.三组研究对象的流行病学史阳性率比较差异有统计学意义(P＜0.05);临床诊断细菌性痢疾患者发病年龄较腹泻待查患者小(P＜0.05).与其他两组患者比较,临床诊断细菌性痢疾患者发病至就诊时间早,呕吐次数多,发热和里急后重发生率高,白细胞、中性粒细胞值和C反应蛋白水平明显升高(P＜0.05).结论 临床诊断急性细菌性痢疾、感染性腹泻和腹泻待查患者在流行病学史、发病年龄、临床表现和实验室检查方面存在一定的差异.“,”Objective To investigate the relationship between clinical parameters related to acute bacterial dysentery and other infectious diarrhea in adults.Methods From April to October 2018,70 patients with clinical diagnosis of acute bacterial dysentery,180 patients with clinical diagnosis of infectious diarrhea and 399 patients with diarrhea to be examined were investigated retrospectively.The collected data included gender,age,time from onset to treatment,maximum body temperature,main symptoms,epidemiological history,blood routine,C-reactive protein and stool routine.Analysis of these clinical factors related to acute bacterial dysentery and other infectious diarrhea.Results A total of 70 patients with acute bacterial dysentery,180 patients with other infectious diarrhea and 399 patients with diarrhea of unknown origin were investigated.The positive rate of epidemiology in the three groups was statistically significant (P ＜0.05);the age of onset of bacterial dysentery was younger than that in patients with diarrhea of unknown orion (P＜O.05).Compared with the other two groups of patients,the onset to visit time was earlier,the number of vomiting was higher,the incidence of fever and tenesmus was higher,and the levels of white blood cells,neutrophils and C-reactive protein were significantly increased (P ＜ 0.05).Conclusions Patients with acute bacterial dysentery,other infectious diarrhea,and diarrhea of unknown origin have some differences in epidemiological history,age at onset,clinical manifestations,and laboratory tests.
