严重肢体损伤截肢与保肢三种评分方法比较

摘要

Objective To compare the values of the mangled extremity syndrome index (MESI), the mangled extremity severity score (MESS) and the limb salvage index (LSI) in deciding amputation or salvage in the management of the mangled extremity syndrome (MES). Methods Clinical data of 353 MES patients including 95 with amputation and 258 with salvage admitted in recent eight years were retrospectively evaluated by using MESI, MESS and LSI, the value of which in deciding amputation or salvage was assessed with receiver operating characteristic ( ROC ). Results There was statistical difference in aspect of mean scores of three grading systems between patients with amputation or salvage (P＜0. 01). For MESI, MESS and LSI, the sensitivities was 89.47%, 85.26% and 83.15% respectively, the specificities was 100%, 96.89% and 96.12% respectively, the coincidence was 97.16%,93.76% and 92.63% respectively, the areas under ROC curves was 0. 924, 0905 and 0. 861 respectively and the cut-off points were equal or over 20, 7 and 6 respectively. Conclusions Three scoring systems are all highly capable of predicting early amputation or not in MES management. The MESI is recommended as a quantitative criterion for determining amputation or salvage.%目的 比较肢体损伤综合征指数(mangled extremity syndrome index,MESI)、肢体严重损伤严重度评分(mangled extremity severity score,MESS)、截肢指数(limb salvage index,LSI)三种评分方法在判断严重肢体损伤截肢与保肢中的价值.方法 对两所医院近8年来收治的353例严重肢体损伤住院患者进行回顾性分析.患者包括95例截肢,258例保肢.应用三种评分方法评分,通过接收者工作特征曲线(ROC曲线)分析,找到截断点检验其判别能力.结果 三种评分均值在截肢和保肢者之间差异均有统计学意义(P＜0.01).MESI、MESS、LSI三种评分方法的截断点分别为≥20分、≥7分、≥6分,灵敏度为89.47%、85.26%、83.15%,特异度为100%、96.89%、96.12%,符合率为97.16%、93.76%、92.63%,ROC曲线下面积为0.924,0.905,0.861.结论 三种评分方法对严重肢体损伤早期截肢与否均有较好预测能力,但MESI的预测能力最好.
