目的探讨双水平式呼吸道正压无创通气配合抗心力衰竭药治疗急性重度左心力衰竭的临床意义。方法急性重度左心衰竭61例,随机分成对照组(G0)、治疗组(G1)两组,G0组为常规药物治疗,G1组在常规药物治疗的基础上应用双水平式呼吸道正压无创呼吸机。比较两组治疗前后临床症状、心率、动脉血气分析和转归。结果 G1组患者较G0组患者能较早改善心力衰竭症状,死亡率低,差异有统计学意义(p<0.05)。结论及早使用双水平正压通气结合抗心力衰竭药治疗急性重度左心衰竭能明显改善心功、患者症状及低氧血症,缩短急性左心衰竭病程,提高抢救成功率。
Objective To investigate the clinical significance of bi-level positive airway pressure non-invasive ventilation combined with anti-heart failure drug in the treatment of acute severe left heart failure. Methods Sixty-one patients with acute severe left heart failure were randomly divided into control group (G0), treatment group (G1) and G0 group. Conventional drug therapy was used in G1 group, and bi-level positive airway pressure machine. The clinical symptoms, heart rate, arterial blood gas analysis and outcome before and after treatment were compared between the two groups. Results Compared with G0 group, patients in G1 group improved symptoms of heart failure earlier, with a lower mortality rate (p <0.05). Conclusions Early treatment of acute severe left heart failure with double-level positive pressure ventilation and anti-heart failure drugs can significantly improve the symptoms of heart function, hypoxemia and shorten the course of acute left heart failure, and improve the success rate of rescue.
