Objective To investigate the risk factors and intervention measures of pulmonary infection after thoracoscopic mediastinal tumor resection. Methods The clinical data of 128 patients who underwent thoracoscopic mediastinal tumor resection in this hospital from June 2016 to June 2017 were retrospectively analyzed, and the incidence of postoperative respiratory tract infection and related risk factors were analyzed, and intervention measures were formulated. Results The incidence of postoperative pulmonary infection was 20.31% in 128 patients with mediastinal tumor resection under thoracoscopy (26/128). Logistic multivariate analysis showed that age over 60, lymph node dissection, preoperative diabetes mellitus, thoracic drainage indwelling time over 3 days, and postoperative wound contamination were all independent risk factors for postoperative pulmonary infection in patients undergoing thoracoscopic mediastinal tumor resection(P<0.05). Preoperative antibiotic prophylaxis and expectoration training were protective factors(P<0.05). Conclusions There are many risk factors for postoperative pulmonary infection in patients undergoing thoracoscopic mediastinal tumor resection, and the preoperative preventive application of antibiotics and the preoperative sputum expectoration and discharge training will help to prevent and reduce the incidence of postoperative pulmonary infection.
