目的:探讨急性左心衰意识障碍患者的通气方法及疗效。方法:在常规治疗的基础上,将68例急性左心衰并意识障碍患者随机分成动态无创通气组(n=35)和有创通气组(n=33),比较两组患者机械通气前后的治疗效果。结果:两组患者经机械通气后呼吸困难均明显改善,在血气指标方面无统计学差异(P>0.05)。结论:意识障碍不是无创通气的绝对禁忌,动态无创通气策略与有创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急性左心衰意识障碍患者的有效方法 。
Objective: To investigate the ventilation and efficacy of patients with acute left heart failure and disturbance of consciousness. Methods: On the basis of conventional treatment, 68 patients with acute left heart failure and disturbance of consciousness were randomly divided into dynamic noninvasive ventilation group (n = 35) and invasive ventilation group (n = 33). Before and after mechanical ventilation treatment effect. Results: Both groups had significant improvement in dyspnea after mechanical ventilation, with no significant difference in blood gas indexes (P> 0.05). Conclusion: The disturbance of consciousness is not the absolute contraindication of noninvasive ventilation. The dynamic noninvasive ventilation strategy is similar to invasive ventilation in the treatment of acute left heart failure. Choosing the appropriate mechanical ventilation according to the condition is an effective way to treat patients with acute left heart failure.
