伤寒病人常存在凝血试验异常和出血并发症,但目前对这种凝血异常的性质和它与出血并发症的关系尚不完全清楚。作者观察56例住院伤寒病人的凝血功能,年龄4～54岁,其中男性31例。病人的诊断依据,主要是骨髓或血细菌学检查阳性,少数为凝集试验阳性。其血浆纤维蛋白浓度如下:①凝血正常者,均值为4.10g/L,高于对照组(3.61g/L);②凝血 Typhoid patients often have clotting test abnormalities and bleeding complications, but the current nature of this coagulation abnormalities and its relationship with bleeding complications is not yet fully understood. The authors observed the coagulation function of 56 patients hospitalized with typhoid fever, aged 4 to 54 years, of whom 31 were males. The basis for the diagnosis of patients, mainly bone marrow or blood bacteriological positive test, a few agglutination test positive. The plasma fibrin concentration as follows: ① clotting normal, mean 4.10g / L, higher than the control group (3.61g / L); ② clotting
