目的 探讨呼吸机在慢性阻塞性肺疾病急性加重期合并Ⅱ型呼吸衰竭患者的价值.方法 收集2014年2月至2016年6月在驻马店市第一人民医院治疗的72例慢性阻塞性肺疾病急性加重期合并Ⅱ型呼吸衰竭患者,随机分为实验组和对照组各36例,实验组患者在基础治疗上加用呼吸机治疗,对照组患者给予常规基础治疗,比较两组患者血气分析结果、气管插管率和死亡率差异.结果 实验组患者PaO2(76.73±1.26)mmHg、PaCO2(54.24±2.09) mmHg、pH为(7.35±0.07),各项指标较对照组均明显改善,差异具有统计学意义(P＜0.05).实验组患者气管插管率为36.11％、死亡率为5.56％,明显低于对照组,具有统计学意义(P＜0.05).结论 对于慢性阻塞性肺疾病急性加重期合并Ⅱ型呼吸衰竭患者采用呼吸机治疗可显著提高治疗效果,改善临床指标,临床值得推广应用.“,”Objective To explore the value of ventilator in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) complicated with type Ⅱ respiratory failure.Methods Seventy-two patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) with type Ⅱ respiratory failure wcre randomly divided into experimental group and control group (n =36) from February 2014 to June 2016.The patients in experimental group Baseline treatment plus ventilator treatment,the control group of patients given conventional basic therapy,compared the two groups of blood gas analysis results,tracheal intubation rate and mortality differences.Results PaO2 (76.73 ±1.26) mmHg,PaCO2 (54.24 ± 2.09) mmHg and pH value (7.35 ± 0.07) in the experimental group were significantly improved compared with the control group (P/u003c0.05).The intubation rate was 36.11％ and the mortality rate was 5.56％ in the experimental group,which was significantly lower than that in the control group (P/u003c0.05).Conclusion Ventilator treatment in patients with acute exacerbation of chronic obstructive pulmonary disease complicated with type Ⅱ respiratory failure can significantly improve the therapeutic effect and improve the clinical indicators,clinical application is worthy of promotion.
