两种院前急救模式治疗急性左侧心力衰竭患者的疗效分析

目的比较两种院前急救模式治疗急性左侧心力衰竭患者的疗效，为提高急性左侧心力衰竭的抢救成功率提供参考。方法将2007年3月至2010年3月在四川省科学城医院急诊科出诊抢救的急性左侧心力衰竭患者随机分为观察组和对照组，观察组41例采用先就地治疗后转运的模武施救；对照组30例采用边转运边治疗的模式救治。比较两组的临床疗效。结果观察组的总有效率为75．0％，对照组的总有效率为51．6％，观察组的总有效率显著优于对照组（Hc=5．13，P〈0．05）；急救后到达急诊室时观察组的呼吸、心率和血氧饱和度均显著优于对照组（P〈0．05）。结论院前急救采用先治疗后转运的模式可提高急性左侧心力衰竭患者抢救的成功率。

The Clinical Analysis of Two Kinds of Prehospital Emergency Mode Treating Acute Left Heart Failure

Objective To compare the clinical effect of two kinds of prehospital emergency modes in the patients with acute left heart failure,and to provide a reference to improve the survival rate. Methods The patients with acute left ventricular failure rescued by Department of Emergency of the Science City Hospital of Sichuan Province during Mar. 2007 and Mar. 2010 were randomly divided into observation group and the control group,the observation group of 41 cases were given rescue on site then transit;the control group were given rescue while transition. The clinical efficacy of the two groups was compared. Results The total effec- tive rate of observation group （ 75.0% ） was higher than the control group （ 51.6 % ） （ Hc = 5.13, P 〈 O. 05 ）. The breathing, heart rate and oxygen saturation of observation group were significantly better than the control group in the emergency room,with statistically significant difference （ P 〈 0.05 ）. Conclusion First rescue then transit mode can improve the success rate in rescuing patients with acute left heart failure.
