目的

探究血栓弹力图(TEG)在早期烧伤后凝血功能障碍诊断的应用研究。

方法

收集2020年01月1日至2021年12月31日在内蒙古医科大学第三附属医院烧伤外科收治的烧伤患者,将患者分为烧伤后凝血功能障碍组与烧伤后非凝血功能障碍组,两组患者行TEG检测和常规凝血和血小板计数检测,统计相关结果并进行分析。

结果

烧伤后凝血功能障碍组和烧伤后非凝血功能障碍组在烧伤总面积(%)[(37.95±15.34)比(11.62±4.17),t=-11.40]比较差异有统计学意义(P<0.05)。凝血功能障碍组(轻度7例、中度8例、重度22例、特重度9例,吸入性损伤26例)与非凝血功能障碍组(轻度31例、中度9例、重度6例、特重度1例,吸入性损伤5例)在烧伤严重程度(χ2=30.75)及吸入性损伤(χ2=20.47)比较差异有统计学意义(P<0.05)。在诊断烧伤后凝血功能障碍时,TEG和常规凝血及血小板检测具有一致性(k=0.664,P<0.05)。烧伤后凝血障碍组TEG参数和常规凝血及血小板结果相关性分析:凝血反应时间(R)值与活化部分凝血活酶时间(APTT)呈正相关(r=0.418,P<0.05);凝血形成时间(K)值与纤维蛋白原浓度(FIB)、血小板(PLT)呈负相关(r=-0.15、-0.413,P<0.05);凝固角(α-Angle)与FIB、PLT 、D-二聚体呈正相关(r=0.618、0.372、0.421,P<0.05);凝固角与凝血酶原时间(PT)呈负相关(r=-0.212,P<0.05);最大血栓振幅(MA)值与FIB、D-二聚体、PLT呈正相关(r=0.29、0.249、0.743,P<0.05);综合凝血指数(CI)值与APTT呈负相关(r=-0.55,P<0.05)。ROC曲线分析:α-Angle、MA值曲线下面积(AUC)分别为0.616、0.754,敏感度为0.617、0.742,特异度为0.705、0.681;常规凝血及血小板检测参数中PT、PLT曲线下面积分别为0.656、0.676,敏感度为0.438、0.469,特异度为0.857、0.632,差异有统计学意义(P<0.05)。

结论

TEG检测对早期烧伤后凝血功能障碍的诊断价值大于常规凝血及血小板计数检测,值得临床应用。

Objective

To explore the application of thromboelastography (TEG) in the diagnosis of coagulation dysfunction after early burns.

Methods

Burn patients admitted to the Department of Burn Surgery of the Third Affiliated Hospital of Inner Mongolia Medical University in the past two years were collected and the patients were divided into post-burn coagulation dysfunction group and post-burn non-coagulation dysfunction group. TEG test and routine coagulation and platelet count test were performed in the two groups, and the relevant results were counted and analyzed.

Results

The post-burn coagulopathy group and the non-coagulopathy group had statistically significant difference in mean burn total area (TBSA%) [(37.95±15.34) vs. (11.62±4.17), t=-11.40] (P<0.05). There were statistically significant differences in burn severity (χ2=30.75) and inhaled injury (χ2=20.47) between the coagulopathy group (7 cases of mild, 8 cases of moderate, 22 cases of severe, 9 cases of extremely severe, and 26 cases of inhaled injury) and the non-coagulopathy group (31 cases of mild, 9 cases of moderate, 6 cases of severe, 1 case of extremely severe, and 5 cases of inhaled injury) (P<0.05). In the diagnosis of post-burn coagulation dysfunction, TEG was consistent with conventional coagulation and platelet tests (k=0.664, P<0.05). Correlation analysis of TEG parameters and routine coagulation and platelet results in post-burn coagulation disorder group showed that R value was positively correlated with APPT (r= 0.418, P<0.05); K value was negatively correlated with FIB and PLT (r=-0.15, -0.413, P<0.05); α-Angle was positively correlated with FIB, PLT, D-dimer (r=0.618, 0.372, P<0.421, P<0.05), and negatively correlated with PT (r=-0.212, P<0.05); MA value was positively correlated with FIB, D-dimer and PLT (r=0.29, 0.249, 0.743, P<0.05); CI value was negatively correlated with APTT (r=-0.55, P<0.05). ROC curve analysis showed that the area under the curve (AUC)of α angle and MA value were 0.616, 0.754, and the sensitivity was 0.617, 0.742, and the specificity was 0.705, 0.681, respectively. The area under the curve of PT and PLT was 0.656, 0.676, the sensitivity was 0.438, 0.469, and the specificity was 0.857, 0.632, repectively; the difference was statistically significant (P<0.05).

Conclusion

TEG detection is more valuable in the diagnosis of coagulation dysfunction after early burn than the conventional detection of coagulation and platelet count, which is worthy of clinical application.
