目的:探讨双水平气道正压通气治疗急性左心力衰竭的疗效。方法:36例急性左心力衰竭患者应用双水平气道正压通气治疗,比较治疗前、后血气分析结果及心率、呼吸频率等指标的变化。结果:36例中28例(77.8%)临床症状在治疗后1~48 h改善,低氧血症逐渐纠正,呼吸困难减轻,原发疾病临床症状及体征减轻,血气分析结果及各项观察指标较治疗前改善(P<0.05)。8例(22.2%)症状无改善者改行气管插管有创机械通气治疗。结论:急性左心力衰竭患者应及早进行双水平气道正压通气治疗。
Objective: To investigate the efficacy of bi-level positive airway pressure ventilation in the treatment of acute left heart failure. Methods: Thirty-six patients with acute left heart failure were treated with bi-level positive airway pressure ventilation. The changes of blood gas analysis results, heart rate and respiratory rate before and after treatment were compared. Results: The clinical symptoms of 28 cases (77.8%) improved in 1 ~ 48 h after treatment, the hypoxemia was gradually corrected, the dyspnea was relieved, the clinical symptoms and signs of the primary disease were alleviated, the results of blood gas analysis and various observation indexes Than before treatment to improve (P <0.05). Eight patients (22.2%) had no improvement in symptoms and had tracheal intubation with invasive mechanical ventilation. Conclusion: Patients with acute left heart failure should be treated with bi-level positive airway pressure as soon as possible.
