Abstract: 【Abstract】 Objective To observe the effect of respiratory function training on postoperative respiratory function and sputum excretion in lung cancer patients with pulmonary lobectomy. Methods Eighty lung cancer patients received pulmonary lobectomy in our hospital from May 2015 to November 2016 were selected as research object，in which 40 cases received routine nursing from May 2015 to February 2016（control group），and received health education，oxygen uptake，aerosol inhalation before and after surgery. Another 40 cases were assigned to observation group and accepted preoperative inspiratory muscle training on the basis of routine nursing from March 2016 to November 2016. The respiratory function pre?and post?operation for 7 d （maximal voluntary ventilation（MVV），forced vital capacity（FVC），forced expiratory volume in one second（FEV1），PaO2，PaCO2），sputum excretion amount，postoperative hospital stays，incidence of complications of two groups were recorded and compared between two groups. Results After surgery，the MVV%，FVC%，FEV1%，PaO2 levels of two groups were lower than before surgery，and PaCO2 level was higher than before surgery（P < 0.05）；After surgery，the MVV%、FVC%、FEV1%、PaO2 levels of control group were lower than those of research group（P < 0.05）. After surgery，there was no statistical difference in the PaO2 level compared between two groups （P > 0.05）. After surgery, the sputum excretion amount of control group was lower than that of research group, and postoperative hospital stays were higher than that of control group（P < 0.05）；After surgery，the total incidence of complications of control group was higher than that of research group（P < 0.05）. Conclusion Preoperative inspiratory muscle training can decrease the postoperative complications for lung cancer patients, which can improve respiratory function, promotion sputum excretion, shorten postoperative hospital stays，reduce risks of complications，and promote patients′ recovery.
