目的 探究支气管镜下肺泡灌洗并局部使用阿米卡星治疗老年支气管扩张合并感染患者的疗效及对血清炎性因子水平的影响。方法 选取我院2018年3月—2019年5月确诊支气管扩张症、合并感染的符合纳入标准的患者共64例,按照1:1比例抽签分为2组,32例纳入观察组,应用支气管镜下肺泡灌洗阿米卡星治疗;32例纳入对照组,以单纯的支气管镜下肺泡灌洗治疗。观察并比较2组患者的治疗效果、血清炎性因子水平、肺功能情况等。结果 疗效比较显示观察组的96.9%总有效率高于对照组的75.0%(P＜0.05);血清炎性因子水平在患者用药前检测无差异(P＞0.05),经过治疗后,观察组水平均优于对照组P＜0.05;经治疗后,观察组静态肺活量、补呼气量、补吸气量、用力肺活量均优于对照组,差异具有统计学意义(P＜0.05)。结论 对老年支气管扩张合并感染患者应用支气管镜下肺泡灌洗阿米卡星治疗,促进临床效果改善,患者的症状、炎症及肺功能等指标均得到明显改善,值得推广。

Objective To investigate the efficacy of bronchoscopic alveolar lavage and local application of amikacin in the treatment of elderly patients with bronchiectasis complicated with infection and its effect on the level of serum inflammatory factors.Methods A total of 64 patients with bronchiectasis complicated with infection diagnosed in our hospital from March 2018 to May 2019 were selected.They were divided into two groups evenly by proportional drawing. Thirty-two cases were included in the observation group that were treated with bronchoscopic alveolar lavage with amikacin.The other 32 cases were included in the control group that were treated with the bronchoscopic alveolar lavage only.The therapeutic effect,serum inflammatory factor level and pulmonary function of the two groups were observed and compared.Results The total effective rate of 96.9% in observation group was higher than 75.0% in control group (P<0.05).There was no difference in the levels of serum inflammatory factors before treatment (P>0.05).After treatment,the levels of the observation group were better than those of the control group (P<0.05).After treatment,the slow vital capacity,expiratory reserve volume,inspiratory reserve volume and forced vital capacity of the patients in the observation group were better than those in the control group (P<0.05).Conclusions Bronchoscopic alveolar lavage of amikacin in elderly patients with bronchiectasis complicated with infection could improve the clinical effect.The symptoms of the patients,the serum inflammatory factors and lung function of the patients were significantly improved.The treatment is worthy of promotion.
