无创面罩机械通气治疗重症急性左心衰竭45例临床观察

Clinical observation on treatment of 45 Cases of severe acute left heart failures with non-invasive mask ventilator

目的观察无创面罩机械通气治疗重症急性左心衰竭的临床疗效。方法回顾性分析45例经常规抗心衰治疗病情不能控制者，紧急采用无创面罩机械通气治疗患者的临床资料。结果缓解35别，抢救成功率达77．8％；上机前后动脉血pH、PaO2、PaCO2和SaO2值以及生命体征（HR、RR）变化差异均有统计学意义（t=1．730、3．267、2．504、2．441、2．701、2．632，均P〈0．05）。结论无创面罩机械通气是抢救重症急性左心衰竭的有效措施。

Objective To observe the clinical treatment of severe acute left heart failures with non-invasive mask ventilator. Methods All patients were conducted on common treatment of heart failure,including high concentration oxygen, tranquillizer, cardiac stimulant, diuretic ,vasodilators and antispasmodic and asthma, etc. , and mechanical ventilation with non-invasive mask ventilator is emergently applied to the patients whose state of illness could not be controlled. Results 35 cases were mitigated and the success rate up to 77.8% ; there were remarkable differences in pH values of arterial blood, PaO2 , PaCO2 , SaO2 and vital signs before and after ventilators were applied （ P 〈 0. 05 ）. Conclusion The non-invasive mask ventilator was an effective measure for treatment of severe acute left heart failure.
