目的 :探讨肥达氏试验在诊断伤寒及副伤寒中的意义。方法 :对经血培养确诊为伤寒和甲型副伤寒 13 0例病例 ,分成人和儿童组 ,在病程的不同阶段作肥达氏试验 ,了解伤寒和副伤寒病人肥达氏试验的阳性率。结果 :伤寒组肥达氏试验阳性率为 80 %～ 86% ,甲型副伤寒组阳性率为 3 2 %～ 3 8% ;伤寒组阳性率与文献报道相符 ,而甲型副伤寒组肥达氏反应阳性率明显低于文献报道 ,成人组和儿童组成二者的肥达氏反应阳性率无明显差异。结论 :临床上在诊断伤寒和副伤寒时不能依赖肥达氏试验 ,对疑似病人在早期做血培养 ,有利于早期确诊。
Objective: To explore the significance of Widal test in the diagnosis of typhoid fever and paratyphoid fever. Methods: One hundred and thirty cases of typhoid fever and paratyphoid A were detected in menstrual blood culture. The patients were divided into adult and children groups, and were used to study the positive rate of fatal test in typhoid and paratyphoid patients at different stages of the course of disease. Results: The positive rate of Widal’s test was 80% -86% in typhoid group and that of paratyphoid A was 32% -38%. The positive rate of typhoid fever was in line with that reported in the literature, The positive reaction rate was significantly lower than that reported in the literature, there was no significant difference in the Widal reaction rate between the adult group and the children. Conclusion: Clinical diagnosis of typhoid and paratyphoid can not depend on the Wadda test, the suspicion of patients in early blood culture, is conducive to early diagnosis.
