中文摘要：

目的探讨盐酸氨溴索氧气面罩雾化吸入疗法在老年患者心脏手术中的应用,为预防心脏手术后呼吸道感染提供参考依据。方法选取医院2013年1月-2014年12月老年患者心脏手术90例患者为研究对象,将其按照随机数字表法分为观察组与对照组,各45例;对照组给予常规α-糜蛋白酶雾化吸入,观察组给予盐酸氨溴索氧气面罩雾化吸入,对比两组患者应用效果,数据采用SPSS 17.0软件进行统计分析。结果观察组雾化吸入治疗时间、痰量减少时间、住院时间分别为（5.2±1.3）（3.2±0.8）（10.5±2.2）d,均明显低于对照组,差异有统计学意义（P〈0.05）;观察组肺不张、肺部感染的发生率分别为2.2%、2.2%,均低于对照组的11.1%与13.3%,差异有统计学意义（P〈0.05）。结论临床中对于心脏手术前应用盐酸氨溴索氧气面罩雾化吸入,可较好的预防术后呼吸道感染,并且改善患者的呼吸道状况,缩短患者的住院治疗时间,值得临床中应用与推广。

英文摘要：

OBJECTIVE To investigate the effect of oxygen atomizing mask inhalation of Mucosolvan in elderly patients undergoing cardiac surgery,and to provide a reference for prevention of respiratory infections after cardiac surgery.METHODS A total of 90 cases of elderly patients underwent cardiac surgery were included in the study from Jan.2013-Dec.2014.With random number table,they were divided into observation group and control group,with 45 cases in each group.The control group received conventionalα-chymotrypsin inhalation,while observation group were given oxygen atomizing mask inhalation of Mucosolvan.Applicative effects of the two groups were compared.RESULTS The inhalation treatment time,sputum volume reducing time,hospital stay of observation group were（5.2±1.3）,（3.2±0.8）,（10.5±2.2）d respectively,which were significantly lower than the control group（P〈0.05）.Atelectasis and lung infection rates of observation group were 2.2%,2.2%,which were significantly lower than 11.1% and 13.3%in control group（P〈0.05）.CONCLUSIONThe clinical application of oxygen atomizing mask inhalation of Mucosolvan before cardiac surgery can prevent postoperative respiratory infection,and improve patient′s respiratory status,shorten hospitalization time,therefore it is worthy of clinical application and promotion.
