文题释义:
血栓弹力图:反映血液凝固动态变化,通过测量期间发生的黏弹性变化,提供了凝血功能的综合评估,而不仅限于评估离散部分。通过测量在止血过程期间发生的黏弹性变化,从初始血小板-血纤维蛋白相互作用开始,通过血小板聚集,凝块强化和纤维蛋白交联到最终凝血溶解,血栓弹力图提供凝血级联的实时功能评价。主要指标包括:反应时间、凝固时间、凝固角、血栓最大幅度。
结构方程模型:通用的多变量分析技术,结构方程分析容许自变量和因变量均含测量误差,增加了整体分析的统计功效,能用于处理传统因子分析难以处理一个指标从属多个因子或者考虑高阶因子等有比较复杂的从属关系的模型。此外,在结构方程分析中,除了上述参数的估计外,还可以计算不同模型对同一个样本数据的整体拟合程度,从而判断哪一个模型更接近数据所呈现的关系。
 
摘要
背景:髋、膝关节置换术后抗凝已列入围手术期处理指南,但应用抗凝药物存在出血风险,常规凝血试验仅针对辨识凝血的第一阶段,所提供出凝血状况的信息相对有限。血栓弹力图可进行凝血功能的综合评估,但其实用性不同研究所得仍不一致,尤其是对关节置换术后出血相关性方面的研究仍鲜见报道。
目的:探讨髋、膝置换术后血栓弹力图凝血反应时间、凝固时间、凝固角、血栓最大幅度值分布情况,同时分析其与总出血量之间的相关性,进一步提高抗凝策略的安全性和有效性。
方法:随机选取2015年8月至2017年3月于中山大学孙逸仙纪念医院行人工关节置换同时接受血栓弹力图检测的患者共148例,其中全髋关节置换患者76例,全膝关节置换患者72例。收集术后第1天血栓弹力图并计算围手术期总出血量,分别构建髋、膝关节置换组结构方程模型,探讨血栓弹力图4个指标与总出血量之间的相关性。
结果与结论:①针对髋、膝置换病例所构建的结构方程模型中,拟合结果近似误差均方根均小于0.08,拟合优度指数、调整拟合优度指数值均高于0.9;比较拟合指数、规范拟合指数均高于0.9;简约适配度指数均小于2,理论模型与数据匹配;②凝血反应时间、凝固时间、凝固角、血栓最大幅度4个值与总出血量之间存在相关性;③综上,血栓弹力图检测可作为预测髋、膝关节置换术后出血的有效工具。未来在此研究基础上所进行的深入研究将进一步验证其相关性,并为临床应用提供更广泛的信息。

Abstract:

BACKGROUND: Postoperative anticoagulant therapy after hip and knee arthroplasties has been included in the perioperative management guidelines. However, the application of anticoagulant drugs accompanies with the risk of bleeding. Routine coagulation tests provide limited information about the quality of clots because they identify only the first stage of clotting, while thrombelastography provides a comprehensive assessment of coagulation function. But its practicality remains controversial and the research for bleeding after joint replacement is little reported.

OBJECTIVE: To explore the distribution of thrombelastography parameters (time to initial fibrin formation, clotting time, α angle, and maximum amplitude) and to analyze the correlation of the four parameters with postoperative blood loss, thereby providing guidance for improving the safety and effectiveness of anticoagulant therapy.
METHODS: Totally148 patients with detection of thrombelastogram after arthroplasty from August 2015 to March 2017 in Sun Yat-sen Memorial Hospital, Sun Yat-sen University were enrolled, including 76 cases of total hip arthroplasty and 72 cases of total knee arthroplasty. Thrombelastography data were collected on day 1 postoperatively, and the perioperative blood loss was calculated. Structural equation modeling of each group was constructed to investigate the relationship of four parameters and total blood loss.
RESULTS AND CONCLUSION: (1) In the structural equation modeling of hip and knee arthroplasties, the root mean square error of approximation was less than 0.08, goodness-of-fit index, adjusted goodness-of-fit index, normed fit index and comparative fit index was all higher than 0.9, and Parsi-mony goodness-of-fit index was less than 2, so the theoretical model was matched with the data. (2) There was a correlation of postoperative hemorrhage with time to initial fibrin formation, clotting time, α angle, and maximum amplitude. (3) That is to say, thrombelastogram can be used as an efficient tool in predicting bleeding after hip and knee arthroplasties. Future study based on this research will further verify the correlation and provide more information for its clinical practice.
