目的观察无创通气和有创机械通气治疗急性左心衰竭的疗效。方法对65例急性肺水肿患者随机分成无创通气组(32例)和有创通气组(33例),比较两组患者机械通气前后治疗效果。结果两组患者经机械通气后呼吸困难均明显改善,心率、呼吸频率、氧分压、二氧化碳分压、中心静脉压及氧合指数等监护指标差异无统计学意义(P>0.05)。无创组和有创组的有效率分别为81.2%和84.8%,差异无统计学意义(P>0.05)。结论无创与有创机械通气治疗急性左心衰竭的疗效相似。根据病情选择合适的机械通气方式,是救治重症急性左心衰竭有效的方法。
Objective To observe the curative effect of non-invasive ventilation and invasive mechanical ventilation on acute left heart failure. Methods Sixty-five patients with acute pulmonary edema were randomly divided into non-invasive ventilation group (32 cases) and invasive ventilation group (33 cases). The therapeutic effects of mechanical ventilation before and after treatment were compared between the two groups. Results The dyspnea of both groups were significantly improved after mechanical ventilation. There was no significant difference in heart rate, respiratory rate, partial pressure of oxygen, partial pressure of carbon dioxide, central venous pressure and oxygenation index between the two groups (P> 0.05). The effective rates of noninvasive group and invasive group were 81.2% and 84.8%, respectively, with no significant difference (P> 0.05). Conclusions The efficacy of non-invasive and invasive mechanical ventilation in the treatment of acute left heart failure is similar. According to the disease to choose the appropriate mechanical ventilation, is an effective treatment of severe acute left heart failure.
