A Study on the Related Factors of Preoperative Airway Colonization Bacteria and Postoperative Pulmonary Complications in Elderly Lung Cancer Patients
Objective To explore the risk factors for preoperative colonization of bacteria and postoperative pulmonary complications in elderly lung cancer patients.Methods A retrospective analysis was conducted on the clinical data of 80 elderly lung cancer patients.All patients underwent preoperative screening for airway colonization bacteria,and the risk factors for preop-erative airway colonization bacteria in elderly lung cancer patients were analyzed based on the presence of positive and negative airway colonization bacteria;After surgery,patients were divided into 2 groups based on the occurrence of pulmonary complica-tions:the occurrence group and the non occurrence group.The risk factors affecting postoperative pulmonary complications in eld-erly lung cancer patients were analyzed.Results The positive rate of airway colonization bacteria in 80 elderly lung cancer pa-tients was 37.50%(30/80),and the incidence of postoperative pulmonary complications was 36.25%(29/80);Univariate analy-sis showed that SP-D and smoking history were associated with preoperative airway colonization bacteria in elderly lung cancer pa-tients(P<0.05);Multivariate analysis showed that SP-D<30ng/ml and smoking were high-risk factors affecting preoperative air-way colonization bacteria in elderly patients with lung cancer(P<0.05 and OR>1);Univariate analysis showed that age,SP-D,smoking history,airway colonization bacteria,and surgery time were associated with the occurrence of postoperative pulmonary complications in elderly patients with lung cancer(P<0.05);Multivariate analysis showed that age≥70 years,SP-D<30ng/ml,smoking,positive airway colonization bacteria,and surgery time≥2 hours were high-risk factors for postoperative pulmonary com-plications in elderly patients with lung cancer(P<0.05 and OR>1).Conclusion Elderly lung cancer patients are affected by factors such as SP-D<30ng/ml and smoking,and preoperative positive airway colonization bacteria are higher.However,age≥70 years,SP-D<30ng/ml,smoking,positive airway colonization bacteria,and surgery time≥2 hours are high-risk factors for postop-erative pulmonary complications in elderly lung cancer patients.Based on this,targeted interventions should be taken during the perioperative period to reduce the risk of postoperative pulmonary complications.
