目的:评价无创正压通气对慢性阻塞性肺疾病引起的呼吸衰竭的治疗价值。方法:回顾性分析35例伴严重Ⅱ型呼吸衰竭的慢性阻塞性肺疾病急性发作期患者的临床资料。结果:无创正压通气3h可迅速改善患者的血气(P<0.05),24～72h可获进一步改善(P<0.01)。治疗成功率88.6%。结论:无创正压通气对以高二氧化碳血症为主要表现的慢性阻塞性肺部疾病并重度呼吸衰竭的患者有良好的治疗效果,对于二氧化碳的排出效果明显。
Objective: To evaluate the therapeutic value of non-invasive positive pressure ventilation on respiratory failure caused by chronic obstructive pulmonary disease. Methods: The clinical data of 35 patients with acute exacerbation of chronic obstructive pulmonary disease with severe type Ⅱ respiratory failure were retrospectively analyzed. Results: Non-invasive positive pressure ventilation for 3h improved the blood gas of patients rapidly (P <0.05), and further improved from 24 to 72h (P <0.01). Treatment success rate of 88.6%. Conclusion: Noninvasive positive pressure ventilation has a good therapeutic effect on patients with chronic obstructive pulmonary disease and severe respiratory failure with high level of carbon dioxide as the main manifestation, and has a significant effect on the discharge of carbon dioxide.
