Objective:To evaluate the preoperative and postoperative management in lung volume reduction surgery for patients with chronic obstructive pulmonary disease.Methods:All 7 patients were male.Age ranged from 65～76 years.Preoperative dyspnea index was grade 4 in 4 and grade 3 in 3.FEV1 were all less than 50%.We performed unilateral Lung volume reduction surgery on the lung that was estimated to have poorer lung function.The resected lung volume was 20%～30% of the operated.Results:2 tracheotomy were performed.Postoperative oxygen supply lasted 6～8d.The symptoms such as palpitaion,dyspnea were improved significantly.FEV1 and dyspnea index were respectively increased by 30%～45% and 1～2 grade.All patients recovered.Conclusions:Preoperative adjustment of the balance of water and electrolyte,proper respiratory exercises,resasonable postoperative oxygn supply and maintenance of unobstructed respiratory tract,all these are important.Moreover,tracheotomy shoulde be perfored promptly in acute cases.
