我院自1979年元月至1982年12月,共收治流行性出血热(EHF)791例,病例的诊断经复查均符合1981年全国防治经验交流会所制订的标准。其中轻型233例,中型319例,重型161例,危重型78例。对791例患者入院时都做血小板检验(结果如表),血小板计数方法用许汝和氏法,正常值为15—25/μl,以少于10万/μl 为减低。检查结果表明,各型病例的血小板数均有明显的减低,尤以危重型最为突出,重型和中型次之,轻型稍少。经统计学处理,轻型与中型相比,X~2=19.62,P<0.005;中型与重型相比,X~2=5.88,P<0.025;重型与危重
Our hospital from January 1979 to December 1982, were treated 791 cases of epidemic hemorrhagic fever (EHF), the diagnosis of the case after review are in line with the 1981 national experience in prevention and control exchanges set by the standards. Among them, 233 were light, 319 were medium, 161 were heavy and 78 were critically ill. The platelet test was performed in 791 patients on admission (results are shown in the table). The platelet counting method was Xu Ruhe’s method, with a normal value of 15-25 / μl and a decrease of less than 100,000 / μl. The test results showed that the number of cases of various types of platelets were significantly reduced, especially in the most critical type, heavy and medium followed, light less. Compared with the medium-sized, X ~ 2 = 19.62, P <0.005, the difference between the medium-heavy and the heavy, X ~ 2 = 5.88, P <
