目的:比较无创与有创通气治疗Ⅱ型呼吸衰竭昏迷的疗效。方法:40例Ⅱ型呼吸衰竭昏迷患者分为无创组和有创组,比较治疗前后血气分析、机械通气时间、住院时间、呼吸机相关性肺炎发生率及病死率。结果:治疗后两组血气分析均改善(P<0.05),机械通气时间、住院时间和病死率接近,无创组呼吸机相关性肺炎发生率低(P<0.05)。结论:Ⅱ型呼吸衰竭昏迷患者可以首先尝试实施无创通气治疗。
Objective: To compare the curative effect of noninvasive and invasive ventilation on type Ⅱ respiratory failure coma. Methods: Forty patients with type Ⅱ respiratory failure coma were divided into noninvasive group and invasive group. The blood gas analysis, mechanical ventilation time, length of hospital stay, ventilator-associated pneumonia and mortality were compared before and after treatment. Results: After treatment, blood gas analysis was improved in both groups (P <0.05). The duration of mechanical ventilation, hospital stay and mortality were similar. The incidence of ventilator - associated pneumonia was lower in the noninvasive group (P <0.05). CONCLUSIONS: Patients with type 2 respiratory failure and coma can first attempt noninvasive ventilation.
