Abstract:Objective To explore the preoperative prehabilitation model based on enhanced recovery after surgery（ERAS） in lung cancer patients with poor lung function treated with operation and its clinical application effect. Methods A total of 91 lung cancer patients with low lung function,who underwent single-hole thoracoscopic lobectomy in Nanjing Brain Hospital from June 2020 to May 2021 were recruited and randomly divided into control group（n=44） and study group（n=47）. The routine preoperative intervention mode was performed in control group, and the prehabilitation mode was conducted in study group before operation. The perioperative self-management ability, the incidence of postoperative pulmonary complications, chest tube retention time, postoperative hospital stay and total length of hospital stay were analyzed and compared between two groups. Results The preoperative completion rate for smoking cessation in study group was significantly higher than that in control group（P＜0.05）. The compliance rates of preoperative anxiety assessment, postoperative early ambulation and voluntary cough in study group were significantly higher than those in control group（P＜0.01）. The incidences of postoperative sputum retention, pleural effusion and lung infection in study group were significantly lower than those in control group（P＜0.01）.The chest tube retention time, postoperative hospital stay and total length of hospital stay in study group were significantly shortened compared with those in control group （P＜0.01）. Conclusion For the lung cancer patients with poor pulmonary function undergoing surgery,the preoperative prehabilitation model can improve perioperative self-management abilities, reduce the incidences of postoperative pulmonary complications and shorten the hospital stay.
