TRISS动态描述曲线在创伤病人中的临床应用

Clinical application of dynamic curve of TRISS in 171 trauma Patients

目的:评估我院171例创伤急救病人的救治结果,对TRISS和TRISS动态描述曲线两种方法进行比较分析。方法:对171例创伤急救病人分别应用TRISS、TRISS动态描述曲线法预测其Ps,并比较其准确性、特异性和敏感性。结果:171例病人存活149例(87.1%),TRISS预测存活157例(91.8%),TRISS动态描述曲线预测存活153例(89.5%),两种方法预测Ps值的准确性、特异性和敏感性间差异均无显著性(均P>0.05),但死亡组Ps值间差异有显著性(P<0.01)。结论:本组创伤病人预后结局与北美创伤数据库预后结局基本相似;TRISS动态描述曲线预测的死亡组Ps值<0.5,与实际相符,可信度较高,且比较直观,优于TRISS法。

Objective ：To evaluate the therapeutic effect of the 171 patients with severe trauma in our hospital and compare the injury severity score （TRISS） with dynamic curve of TRISS. Methods：The survival probability of 171 trauma patients was calculated by TRISS and dynamic curve of TRISS and their accuracy,specificity and sensitivity were compared. Results：Among the 171 eases,the actual survival was 149 cases（87.1%） ,the survival expected by TRISS was 157 cases（91.8%） and 153 cases （89.5%） by dynamic curve of TRISS. There was no significant difference in accuracy, specificity and sensitivity between the two methods （P〉0.05）,but significant difference in the survival probability of dead group （P〈0.01）. Conclusion：The prognosis result in this group is about equal to that of north american trauma data base. The survival probability in dynamic curve of TRISS group is less than 0.5, which is more reliable,intuitional and better than that in TRISS group.
