目的 评价院前急救中应用无创正压机械通气辅助治疗急性左心衰的临床疗效。方法回顾性分析2006年2月至2009年12月我中心院前救治并转运的急性左心衰患者85例,根据有无应用无创正压机械通气将病例分成治疗组与对照组,对两组治疗前后的临床症状、血压、心率、呼吸频率、血氧饱和度进行比较及分析。结果治疗组疗效与对照组比较有统计学差异(P<0.5)。结论院前抢救急性左心衰患者时,在常规治疗的同时辅以无创正压机械通气疗效优于单纯药物治疗组。
Objective To evaluate the clinical efficacy of noninvasive positive pressure mechanical ventilation in the treatment of acute left heart failure in pre-hospital emergency department. Methods A retrospective analysis of 85 patients with acute left heart failure who were treated and transfused in our center from February 2006 to December 2009 was divided into treatment group and control group according to the presence or absence of noninvasive positive pressure mechanical ventilation. Before and after treatment of clinical symptoms, blood pressure, heart rate, respiratory rate, oxygen saturation were compared and analyzed. Results The curative effect in the treatment group was statistically different from that in the control group (P <0.5). Conclusion Prehospital rescue of patients with acute left heart failure, conventional treatment combined with noninvasive positive pressure mechanical ventilation is superior to the simple drug treatment group.
