家庭无创正压通气在慢性阻塞性肺疾病稳定期患者中的疗效

目的 研究稳定期慢性阻塞性肺疾病并慢性呼吸衰竭患者家庭氧疗加用无创正压通气与单独应用家庭氧疗治疗的疗效.方法 慢性阻塞性肺疾病稳定期并慢性呼吸衰竭患者使用家庭氧疗加无创正压通气与单纯长期家庭氧疗患者比较在治疗1年中的病情恶化次数、住院次数、住院时间以及治疗前与治疗12个月后的血气指标和肺功能参数的变化和症状、体征.结果 随访12个月后,家庭氧疗加用无创正压通气治疗组病情恶化次数和住院次数均较单纯氧疗组明显减少.在治疗12个月随访时,家庭氧疗加用无创正压通气治疗组的动脉血氧分压(PaO2),动脉血二氧化碳分压(PaCO2),血液pH与单纯氧疗组比较均有显著改善,差异有统计学意义(P<0.05).结论 无创正压通气是慢性阻塞性肺疾病稳定期并慢性呼吸衰竭患者积极和有效的治疗措施.Abstract：Objective To study the clinical value of home non-invasive positive pressure ventilation(NIPPV) in patients with stable-phase chronic obstructive pulmonary disease(COPD)and chronic respiratory failure.Methods Stable COPD patients complicated with chronic respiratory failure received Bi-level positive airway pressure ventilation.The frequency of acute exacerbation,admissiontimes-admission expending,blood gas analysis were compared in these patients with those received long term oxygen therapy. Results After one year home non-invasive positive pressure ventilation,PaCO2,HCO-3 were decreased,while pH and PaO2 increased.Compared with patients received long term oxygen therapy,PaCO2 was greatly ameliorated and the frequency of acute exacerbation,admission times and admission expending declined.Conclusions Home non-invasive positive pressure ventilation will do good to COPD patients with hypercapnic respiratory failure during stable phase.
