目的：探讨按照2013版急性缺血性卒中的早期治疗指南要求的院外急救流程对脑卒中的救治影响。方法分析武汉市急救中心利济北路站经洛杉矶院外中风筛检表（LAPSS）筛查可疑中风的57例患者为标准组，严格按照指南完成相关评估和管理，见表1。但汉西分站仅完成普通的院外急救措施。同期武汉市急救中心汉西分站的52例患者为对照组，比较两组患者的自救时间、院外救治时间、院内急救时间、住院天数和脑梗塞患者的溶栓率。结果标准组的院外急救时间、院内急救时间明显少于对照组，差异有统计学意义（P <0.05）。标准组脑梗塞患者的溶栓率高于对照组，中风患者的住院天数少于对照组，差异有统计学意义（P 0.05）。结论标准化的急救流程能减少患者的抢救时间，减少致残率和病死率，降低患者的经济负担。“,”Objective To explore the effect of treatment guidance for stroke on its early stage in pre-hospital emergency medical services (EMS). Methods 57 suspected acute stroke patients were screened and analyzed with Los Angles pre-hospital stroke screen (LAPSS) in Wuhan Emergency Medical Center Lijibeilu Station which served as standardization group while 52 patients were treated with conventional pre-hospital emergency procedures in at Hanxi Station which served as control group. A comparison analysis was made on time length of self-help, pre-hospital, in-hospital emergency treatment, the hospital stay, as well as thrombolysis rates between the two groups. Results Comparing with the control group, the time length of pre-hospital and in-hospital emergency treatment of standardization group was much shorter (P <0.05); its thrombolysis rate of acute cerebral infarction of standardization was higher (P <0.05); its hospital stay was shorter (P <0.05). No significant difference was found in self-help time between two groups (P <0.05). Conclusion The specification process of EMS is considered being effective in shortening rescue time, reducing the mortality and disability as well as the patient’s financial burden.
