Risk factors for pulmonary complications after thoracoscopic lung resection and the prediction value / 中华麻醉学杂志

ABSTRACT

Objective:To identify the risk factors for postoperative pulmonary complications (PPCs) after thoracoscopic lung resection and evaluate the predictive value for the development of PPCs.Methods:The perioperative data of patients, aged≥18 yr, of American Society of Anesthesiologists (ASA) physical statusⅠ-Ⅲ, were obtained through the electronic medical record system.The blood routine within 24 h after surgery was recorded, and systemic immune-inflammation index (SII) was calculated.According to the development of PPCs, the patients were divided into non-PPCs group and PPCs group.Multivariate logistic regression analysis was used to analyze the variables of which P values were less than 0.05 to identify the risk factors for PPCs, and the receiver operating characteristic curve was drawn to evaluate the predictive value of risk factors. Results:A total of 699 patients were enrolled in this study, including 620 patients in non-PPCs group and 79 patients in PPCs group.The results of logistic regression analysis found that body mass index ≥25 kg/m 2, ASA physical status Ⅲ, lung segmental resection, resection of lobes or above, multi-port thoracoscopic surgery and increased postoperative SII were the risk factors for PPCs ( P<0.05 or 0.01). The AUC (95% confidence interval) of postoperative SII in predicting PPCs was 0.636 (0.599-0.671) ( P<0.05), the cut-off value of SII in predicting PPCs was set at 1 052.3, and the sensitivity and specificity were 68.4% and 57.3%, respectively. Conclusions:Body mass index ≥25 kg/m 2, ASA physical status Ⅲ, lung segmental resection, resection of lobes or above, multi-port thoracoscopic surgery and increased postoperative SII are the risk factors for PPCs.Postoperative SII can predict the occurrence of PPCs to a certain extent in the patients undergoing thoracoscopic lung resection.
