目的观察于急性左心衰行机械通气的治疗效果。方法选取18例急性左心衰的患者行机械通气治疗的临床资料,比较患者于机械通气治疗前后患者的心率、血压、呼吸频率、血气分析及血流机械通气治疗的动力学的变化。结果机械通气治疗2h后,患者前诉观察指标均较治疗前显著改善,2例死亡,病死率为11.1%。结论有创机械通气治疗是抢救急性左心衰的有效辅助治疗措施。 Objective To observe the effect of mechanical ventilation on acute left heart failure. Methods The clinical data of 18 patients with acute left heart failure who underwent mechanical ventilation were collected. The changes of heart rate, blood pressure, respiratory rate, blood gas analysis and mechanical ventilation were compared before and after mechanical ventilation therapy. Results After 2 hours of mechanical ventilation, the observed index of patients before treatment was significantly improved compared with that before treatment. Two patients died and the case fatality rate was 11.1%. Conclusion Invasive mechanical ventilation is an effective adjuvant therapy for acute left heart failure.
