     摘要：目的探讨297例创伤性死亡患者的临床流行病学特点及高危因素对其预后的影响。方法采用ISS、RTS、TRISS及%LD50等创伤评分指标，对297例创伤性死亡患者的相关临床资料进行定量评价和统计学处理，并对影响预后的高危因素进行比较研究和量化分析。结果颅脑损伤和失血所致死亡者分别为98例(33%)和113例(38.38%)，器官功能衰竭死亡者34例(11.45%)；平均救治时间为(44.12±16.47)分钟，伤后的救治时间与平均最大救治允许时间的差值与死亡率具有明显相关性(r＝0.416，P<0.01)；全组生存概率(Ps)为0.39±0.28，并发症发生率为24.92%；可防止的死亡率(PDR)为51.78%；非预期死亡35例。结论颅脑损伤和失血是伤后主要死因，后期多死于并发症或器官衰竭；颅脑和躯干创伤严重影响伤员存活率。提高救治水平有助于提高伤员生存率。

    Abstract： Objective To investigate the feature of epidemiology and influence of lethal factors in trauma patients.Methods The clinical data of 297 patients were reviewed in measured evaluation and statistic process with the trauma index of RTS,AIS,ISS TRISS and %LD50.Risk factors affecting prognosis were conducted by compared study and quantitative analysis for death in trauma patients.Results Nintyeight death(33%) was caused by brain injury and 113 deaths(38.38%) was caused by exsanguination.Thirtyfour deaths(11.45%) were due to organ failure.Average time used in treatment was(44.12±16.47)min ......
