目的:评价不同连接方式的机械通气在重度COPD合并II型呼衰患者中的治疗效果。方法:41例重度COPD合并II型呼衰患者在常规药物治疗的基础上按不同的气道连接方式分为三组:A组13例,为面罩机械通气,B组14例,为经口气管插管机械通气;C组14例,为气管切开机械通气。结果:机械通气24h后,A组各项指标改善不明显(P>0.05)。B、C组PCO2、PO2、PH值均较前有明显改善,相比有显著差异性(P<0.01),并且优于A组。在改善心率呼吸方面C组优于A、B组。结论:重度COPD合并II型呼衰患者有创机械通气疗效较无创面罩机械通气肯定,气管切开患者的依从性明显优于经口气管插管。
PURPOSE: To evaluate the therapeutic effect of different types of mechanical ventilation on patients with severe COPD and type II respiratory failure. Methods: Thirty-one patients with severe COPD and type II respiratory failure were divided into three groups according to the different methods of airway connection: group A (13 cases), mask ventilation (group B), group B (14 cases) Intubation mechanical ventilation; C group of 14 cases, tracheotomy mechanical ventilation. Results: After 24h of mechanical ventilation, the indexes of group A did not improve obviously (P> 0.05). B, C group PCO2, PO2, PH values were significantly improved compared with the previous, compared with significant differences (P <0.01), and better than the A group. C group was better than A and B group in improving heart rate respiration. Conclusions: The mechanical ventilation of patients with severe COPD and type II respiratory failure is better than the mechanical ventilation without invasive mask, and the compliance of patients with tracheostomy is better than that of orotracheal intubation.
