目的:探讨补中益气方对慢性阻塞性肺疾病(COPD)急性加重期(AECOPD)合并呼吸衰竭患者临床效果及呼吸机使用时间的影响。方法:选取高密市人民医院2017年7月至2019年2月治疗的AECOPD合并呼吸衰竭患者64例，采用随机数字表法分为治疗组、对照组各32例。对照组采用常规疗法，治疗组在常规疗法基础上加用补中益气方治疗。比较两组患者治疗前后动脉血气分析指标及呼吸机使用时间。结果:治疗组呼吸机使用时间、重症医学科住院时间分别为(14.56±3.52)d、(17.58±4.95)d，均短于对照组的(16.59±2.89)d、(20.37±5.62)d，两组差异均有统计学意义(n t＝4.76、5.04，均n P0.05)。n 结论:补中益气方可有效改善AECOPD呼吸衰竭患者炎性反应，提高临床疗效，缩短呼吸机使用时间。“,”Objective:To study the effect of Buzhong Yiqi Recipe on the use time of ventilator in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods:From July 2017 to February 2019, 64 patients with AECOPD and respiratory failure treated in People's Hospital of Gaomi were divided into two groups according the random digital table method, with 32 cases in each group.The control group was treated with routine therapy, and the treatment group was treated with Buzhong Yiqi formula on the basis of routine therapy.The arterial blood gas index and ventilator time before and after treatment were compared between the two groups.Results:The mechanical ventilation time, intensive care unit hospitalization time of the treatment group was (14.56±3.52)d, (17.58±4.95)d, which were shorter than that those of the control group [(16.59±2.89)d, (20.37±5.62)d], and the differences were statistically significant(n t=4.76, 5.04, all n P0.05).n Conclusion:Buzhong Yiqi Recipe can shorten the use time of ventilator in AECOPD patients with respiratory failure.
