血栓弹力图在主要外科手术围手术期中的应用

影响围手术期凝血功能的因素具有多样性,目前检测凝血功能的方法包括凝血酶原时间(PT)、活化部分凝血酶原时间(APTT)、血小板(PLT)计数、纤维蛋白原(FIB)浓度等传统凝血检测项目和血栓弹力图(TEG),而传统的凝血检测只能监测凝血过程中的一部分,不能反映凝血的动态变化,无法准确判断凝血异常的原因。TEG可以快速、准确、全面、动态地监测血液凝固的全过程,合理地评估围手术期的凝血功能,为临床治疗提供理论依据。

Application of thrombelastography in perioperative period of surgical operations

There are various factors influencing coagulation function during operation. Nowadays, prothrombin time (PT), activated partial thromboplastin time (APTT), platelet (PLT) count, fibrinogen (FIB), parameters from other conventional coagulation tests and from thrombelastography (TEG) are common indicators for coagulation function assessment. However, tests for those traditional indicators can only monitor some parts of clotting, and thus, the indicators can not reflect the dynamic changes of blood coagulation. So it is impossible to determine the causes of abnormal coagulation. Thrombelastography, a rapid, accurate, all-sided, and dynamic method to monitor the whole process of coagulation, can evaluate the coagulation function rationally in perioperative period and provide theoretical basis for clinical treatment.
