Abstract: Objective To observe the role of preoperative lung function test in predicting the risk of postoperation pulmonary complications in patients with chronic obstructive pulmonary disease (COPD) accepting non chest operations. Methods 80 patients accepting non-invasive chest operations during Oct 2006 to May 2013 in the third affiliated hospital of SYSU were studied retrospectively. All the patients accepted lung function test 1 week before operation. Based on the lung function records, patients were divided into 2 groups. 40 of them in COPD group, 40 in control group. The incidence rate of postoperation pulmonary complications in different group and the relationship between the severity of lung function decreasing and the rate of postoperation pulmonary complications were investigated. The differences of the American Society of Anesthesiologists (ASA) Physical Status Classification, body mass index, smoking index, length of stay, hospitalization costs between the 2 groups were also studied. Results The incidence rate of postoperation pulmonary disease in COPD group was 30% (12/40) while the rate in control group was 12.5% (5/40), the statistic difference was significant (P = 0.046). There was remarkable relationship between the severity of lung function decreasing and the rate of postoperation pulmonary complications(P=0.005), patients with mild to moderate lung function decreasing would be safer in operation, but patients with severe lung function decreasing would be in high risk(r=-0.451). Patients in COPD group were older than the control group, but there were no significant difference on body mass index, smoking index, length of stay, hospitalization costs between the 2 groups (P > 0.05). There was no relationship between ASA physical status classification and postoperation pulmonary complications. Conclusion Incidence of postoperation pulmonary complications in patients with COPD is high, which mainly manifests as pneumonia. It was important to test the lung function before non-invasive chest operations, especially in patients with COPD(P>0.05).
