摘　　要：目的研究早期机械通气对急性重症心力衰竭患者预后的影响。方法急性重症心力衰竭患者68例,随机分为早期机械通气组(n=34)和常规机械通气组(n=34),比较症状缓解时间、机械通气时间、7 d病死率的差别。结果两组患者在症状缓解时间方面(4.7±1.7 h vs 5.0±1.8 h,P>0.05);在机械通气时间方面,早期机械通气组显著低于常规机械通气组(15.6±4.5 h vs 33.1±13.4 h,P<0.01);早期机械通气组7 d病死率也显著低于常规机械通气组(8.9%vs 26.7%,P<0.05)。结论早期机械通气可降低急性重症心力衰竭患者病死率。Objective To investigate the effect of early mechanical ventilation on mortality of patients with severe acute ventricular failure.Methods Ninety patients with acute left ventricular failure were divided into early mechanical ventilation group（n=34） and conventional mechanical ventilation group（n=34）.Time of symptomatic relief,duration of mechanical ventilation and the morality on 7 days were observed.Results There was no difference in time of symptomatic relief between the two groups（4.7±1.7 h v.s 5.0±1.8 h,P0.05）;but the duration of mechanical ventilation was significantly shorter in the early mechanical ventilation group than that in conventional mechanical ventilation group（15.6±4.5 h vs 33.1±13.4 h,P0.01）;and the mortality on 7 days was significantly lower than that in conventional mechanical ventilation group（8.9% vs 26.7%,P0.05）.Conclusion Early mechanical ventilation can decrease the mortality of patients with severe acute ventricular failure.
