真空采血管内壁处理剂对血清TT3和TT4及TSH检测的影响

目的：评价一种真空采血管内壁处理剂对甲功三项检测结果的影响。方法采用内壁处理剂处理的玻璃管与未经过内壁处理剂处理的玻璃管生产的无抗凝真空采血管,对20例健康人进行采血测试,考察两种无抗凝管的血清分离效果及在三个不同的检测平台上总三碘甲状原氨酸（TT3）、总甲状腺素（TT4）、促甲状腺激素（TSH）检测值的差异。结果经过内壁处理剂处理的玻璃无抗凝管与未经过内壁处理的玻璃无抗凝管采血后分离血清,经过内壁处理的玻璃无抗凝管没有纤维蛋白挂壁情况；TT3、TT4、TSH在贝克曼DXI800、西门子Centaur、雅培i2000检测平台上检测,经过内壁处理的玻璃无抗凝管的TT3均值分别为3.10、2.38、2.07 nmol/L,标准差分别为0.42、0.38、0.31；TT4均值分别为102.44、102.34、103.15 nmol/L,标准差分别为15.49、16.25、17.56；TSH均值分别为2.25、2.21、2.29 mIU/L,标准差分别为1.29、1.27、1.38；未经内壁处理的玻璃无抗凝管的TT3均值分别为2.06、1.99、2.08 nmol/L,标准差分别为0.28、0.48、0.30；TT4均值分别为102.82、103.46、101.80 nmol/L,标准差分别为16.48、16.66、16.17；TSH均值分别2.26、2.25、2.23 mIU/L,标准差分别为1.33、1.28、1.28。TT3在贝克曼DXI800检测平台差异具有统计学意义（P＜0.01）。结论在某些检测平台上,真空采血管内壁处理剂L-720会对血清TT3检测造成干扰。

Intervention analysis of a large number of component blood transfusion on blood coagulation mechanism

ObjectiveTo analyze intervention of a large number of component blood transfusion on blood coagulation mechanism.MethodsRetrospectively analyzed clinical data of 73 patients with a large number of component blood transfusion. The infusion of suspension red blood cell volume average of 11 U, infusion of average frozen plasma volume of 8 U. Blood clotting index 4 h before and after blood transfusion was detected.Results73 cases of patients before and after blood transfusion blood coagulation factor had significant changes, the difference was statistically significant（P〈0.01）, blood platelet reducted significantly, the difference was statistically significant（P〈0.01）.ConclusionA large number of component blood transfusion has important influence on blood coagulation function, blood platelet and clotting factors should be timely detected, and through blood heat and corresponding platelet and blood coagulation factor supplementary to reduce risk of bleeding.
