无创正压通气治疗AECOPD合并Ⅱ型呼吸衰竭的临床疗效观察

摘要

Objective To observe the curative effect of Bi - level Positive Airway Pressure Non - invasive mechanical treatment to AECOPD patients with type II respiratory failure. Methods A total of 79 patients who suffered from AECOPD with type II respiratory failure were divided into two groups. The therapy group included 39 patients who were given routine treatment ( meditations and oxygen ) and Bi -PAP non - invasive ventilation; the contrast group included 40 patients who were only given routine treatment. Arterial blood gases before and after treatment, the clinical symptom were observed and compared. Results After 7 days treatment, the arterial Ph and PaO2 increased significantly in the therapy group ( P <0. 01 ), and PaCO2 decreased significantly ( P <0. 01 ). The heart rate and the respiratory rate were also improved significantly( P<0.05 ). The arterial blood gases and the clinical symptom of the therapy group were improved more significantly than the contrast group( P <0. 05 ). Conclusion The use of Bi - PAP non - invasive ventilation in AECOPD patients with type II respiratory failure is effective in improving arterial blood gases and the clinical symptom.%目的 观察双水平无创正压通气治疗慢性阻塞性肺疾病急性加重期(acute exacerbation of chronic obstructive pulmonary disease,AECOPD)合并Ⅱ型呼吸衰竭患者的疗效.方法 79例AECOPD合并Ⅱ型呼吸衰竭的患者,随机分为使用Bi-PAP无创呼吸机行双水平正压辅助通气治疗组(治疗组,39例)和常规治疗组(对照组,40例),观察和比较两组患者治疗前后临床症状及动脉血气的变化情况.结果 治疗组患者在治疗7天后pH、PO2、PCO2结果均较治疗前明显改善(P<0.01),心率及呼吸频率也明显改善(P<0.05),且治疗组与对照组比较各项指标改善更明显(P<0.05).结论 Bi-PAP无创呼吸机双水平正压辅助通气治疗AECOPD合并Ⅱ型呼吸衰竭患者有显著的疗效,值得临床推广及应用.
