为确定院外急救时间间隔是否与城市重大创伤患者的意外存活和死亡相关，回顾性分析了1年内由EMS系统录入的城市重大创伤患者，采用TRISS方法确定意外死亡或意外存活患者。使用非配对t检验（双尾分析）比较两组的EMS响应、现场时间、转运时间和总EMS院外时间间隔。在848例重大创伤病例中，有13例（1.5%）意外幸存者和20例（2.4%）意外死亡。在完成EMS时间的患者中，意外幸存者的平均院外响应时间间隔明显较短（3.5 +/- 1.2分钟vs 5.9 +/- 4.3分钟; P= 0.04）。平均EMS现场时间间隔（7.8 +/- 4.1分钟vs 11.6 +/- 6.5分钟; P= 0.06）和平均转运时间间隔（9.5 +/- 4.4分钟vs 11.7 +/- 4.0分钟; P= 0.17）也有利于意外幸存者组。总体而言，意外幸存者的总EMS时间间隔显著较短（20.8 +/- 5.2分钟vs 29.3 +/- 12.4分钟; P= 0.02）。得出的结论是，一个短的整体院外时间间隔可能会积极影响患者的生存在选定的城市重大创伤患者。版权所有（C）1995由W.B.桑德斯公司
To determine if out-of-hospital emergency medical services (EMS) time intervals are associated with unexpected survival and death in urban major trauma, a retrospective review was conducted of major trauma cases entered into an urban trauma system by an EMS system during a one-year period, Patients with unexpected death or unexpected survival were identified using TRISS methodology. The EMS response, on-scene time, transport time, and total EMS out-of-hospital time intervals were compared for the two groups using the unpaired t test (two-tailed analysis). Of 848 major trauma cases, there were 13 (1.5%) unexpected survivors and 20 (2.4%) unexpected deaths, Of those patients with complete EMS times, the mean out-of-hospital response time interval was significantly shorter for the unexpected survivors (3.5 +/- 1.2 minutes v 5.9 +/- 4.3 minutes; P=.04). The mean EMS on-scene time interval (7.8 +/- 4.1 minutes v 11.6 +/- 6.5 minutes; P=.06) and the mean transport time interval (9.5 +/- 4.4 minutes v 11.7 +/- 4.0 minutes; P=.17) also favored the unexpected survivor group. Overall, the total EMS time interval was significantly shorter for unexpected survivors (20.8 +/- 5.2 minutes v 29.3 +/- 12.4 minutes; P=.02). It was concluded that a short overall out-of-hospital time interval may positively affect patient survival in selected urban major trauma patients. Copyright (C) 1995 by W.B. Saunders Company
