中文摘要：

目的：探讨术前氧气雾化吸入沐舒坦对胸外科术后患者咳嗽频率、痰液黏稠度、肺部并发症的影响。方法：将148例患者随机分为观察组73例和对照组75例,对照组执行常规护理,观察组在常规护理基础上术前给予氧气雾化吸入小剂量沐舒坦。比较两组患者咳嗽频率、痰液黏稠度、排痰效果、肺部并发症发生情况。结果：两组患者术后第4 d咳嗽频率、痰液黏稠度、排痰效果、肺部并发症发生情况比较有统计学意义（P〈0.05）。结论：术前氧气雾化吸入沐舒坦能减少胸外科术后患者的咳嗽频率,降低痰液黏稠度,改善排痰效果,降低肺部并发症发生,增加患者舒适感,促进患者顺利康复。

英文摘要：

Objective：To investigate the effect of preoperative oxygen atomizing inhalation of Mucosolvan on the postoperative patients in chest surgery with cough frequency,phlegmy fluid viscosity and pulmonary complications.Methods：The 148 cases were randomly divided into observation group and control group with 73 cases and 75 cases respectively.Control group performed routine nursing,observation group based on routine nursing,preoperative oxygen atomizing inhalation of small doses of Mucosolvan were given.The incidence of cough frequency,phlegmy fluid viscosity,the effects of discharging sputum and pulmonary complications were compared between the two groups.Results：Two groups had statistics significance in the cough frequency,phlegmy fluid viscosity,effects of sputum,pulmonary complications on the fourth days after postoperation（P0.05）.Conclusion：Oxygen atomizing inhalation of Mucosolvan before operation on the postoperative patients in chest surgery may decrease cough frequency and reduce phlegmy fluid viscosity,improve the effects of discharging sputum and decrease the pulmonary complications effectively,also can increase the patients comfort and prompt the rehabilitation.
