In recent years, with the improvement of CT resolution, the reduction of radiation dose, the popularization of lung cancer screening and the enhancement of people's health awareness, the detection rate of lung nodules is higher and higher. Due to the close relationship between lung nodules and lung cancer, more and more attention has been paid to them. Although patients with early and middle stage lung cancer receive complete resection, all postoperative patients are at risk of recurrence and metastasis. Adjuvant or neoadjuvant therapy can improve the survival and reduce the recurrence and metastasis. Therefore, the multidisciplinary team, as the best model, provides a standardized and individualized plan for the diagnosis and treatment of lung nodules and lung cancer patients. However, in the clinical practice, the work efficiency of the multidisciplinary team is not high, and the participation rate of patients is low; therefore the multidisciplinary doctor model with thoracic surgeons as the mainstay is a reasonable alternative.

Objective To study the distribution and drugresistance of pathogens isolated from patients who suffered from lower respiratory infections after thoracotomy and provide basis for rational use of antibiotics in clinical practice. Methods A total of 118 patients suffered from lower respiratory infections after thoracotomy in Beijing Lung Cancer Center and the Thoracic Surgery Department of Xuanwu Hospital between January 1,2006 and December 31, 2009. We performed a retrospective study on pathogens from their lower respiratory tract. Of these patients, 89 are male and 29 are female with a mean age of 64.6 years. Sputum specimens were obtained by sterile sputum collectors or bronchofibroscopes, and then were sent to microorganism laboratory immediately. Cytological screening was carried out before specimen inoculation. Bacterial culture, identification and drug sensitivity test were performed with routine methods. Results A total of 201 strains of pathogens from the lower respiratory tract were identified. There were 126(62.7%) strains of gramnegative bacilli, 66(32.8%) strains of grampositive cocci, and 9(4.5%) strains fungi. The four prevalent gramnegative bacilli strains with the highest isolating rate between 2006 and 2009 included 34(27.0%) strains of acinetobacters, 28(22.2%) strains of verdigris Pseudomonas, 19(15.1%) strains of Klebsiellas and 19(15.1%) strains of Escherichia coli. Verdigris Pseudomonas ranked first in isolating rate among prevalent gramnegative bacilli strains from 2006 to 2008, but it was replaced by cinetobacters (9 strains, 40.9%) in 2009. The most prevalent strains of grampositive cocci were staphylococcus aureus (35 strains, 53%) from 2006 to 2009. Gramnegative bacilli were most sensitive to imipenem and no grampositive cocci were resistant to vancomycin. Conclusion Gramnegative bacilli are the most common pathogens in lower respiratory infections after thoracotomy and show extremely high drugresistance rate. Drugresistance monitoring of pathogens should be promoted. It may contribute to rational antimicrobial therapy and effective control of infections.
ObjectiveThe clinical trial evidence and expert consensus in the airway management were systematically summarized in this guideline to provide clinical guidance for healthcare professionals.MethodsA total of 40 clinical questions were proposed by 32 experts, and 12 clinical questions were finally identified through the Delphi method and the PICO (patient, intervention, control, outcome) principle from 2019 to 2020. PubMed, Web of Science, Wanfang database and CNKI were searched from establishment of each database up to November, 2020. The evidence of 160 articles was graded according to GRADE method, including 18 in class A, 36 in class B, 69 in class C, and 37 in class D. Four symposiums were organized for discussion of the recommendations. Finally, 23 recommendations were made for these 12 clinical questions, among which 10 were strongly recommended and 13 were weakly recommended.ResultsSmoking cessation for at least 4 weeks, pulmonary function assessment and pulmonary rehabilitation exercise were recommended in the perioperative period, especially at least 1 week of pulmonary rehabilitation exercise for the patients with high risk factors. Anesthesia was maintained by inhalation or intravenous anesthesia. It was recommended to choose short acting drugs, monitor the depth of anesthesia and muscle relaxation during operation, and use protective ventilation strategy. Postoperative use of drugs and mechanical measures to prevent venous thromboembolism, the appropriate application of drainage tube, preemptive analgesia and multimodal analgesia for pain management were recommended. Inhaled corticosteroids with bronchodilators could be used in perioperative period to reduce airway hyperresponsiveness and postoperative cough.ConclusionFor perioperative airway management, smoking cessation, pulmonary function assessment and pulmonary rehabilitation exercise are recommended in the perioperative period. The rational use of anesthetic drugs and protective ventilation strategy are emphasized during the operations. Postoperative pain management and cough treatment should be strengthened, and drainage tube should be used properly.
ObjectiveTo explore and analyze the related influencing factors for common intraoperative complications during CT-guided percutaneous radiofrequency ablation of pulmonary tumor. MethodsWe retrospectively analyzed the clinical data of the patients who underwent CT-guided percutaneous radiofrequency ablation of pulmonary tumor in our hospital from December 2018 to December 2019, and analyzed the influencing factors for complications. ResultsA total of 106 patients were enrolled. There were 58 (54.7%) males and 48 (45.3%) females aged 46-81 (68.05±8.05) years. All patients successfully completed the operation. The operation time was 47.67±16.47 min, and the hospital stay time was 2.45±1.35 d. The main intraoperative complications were pneumothorax (16.0%, 17/106) and intrapulmonary hemorrhage (22.6%, 24/106). Univariate analysis showed that the number of pleural punctures had an impact on the occurrence of pneumothorax (P=0.00). The length of the puncture path (P=0.00), ablation range (P=0.03) and ablation time (P=0.00) had an impact on the occurrence of intrapulmonary hemorrhage. Multivariate logistic regression analysis showed that the size of the lesion (OR=17.85, 95%CI 3.41-93.28, P=0.00) and the number of pleural punctures (OR=0.02, 95%CI 0.00-0.11, P=0.00) were independent influencing factors for the occurrence of pneumothorax. The length of the puncture path (OR=15.76, 95%CI 5.34-46.57, P=0.00) was the independent influencing factor for the occurrence of intrapulmonary hemorrhage. ConclusionPercutaneous radiofrequency ablation of pulmonary tumor is safe and with a high success rate, but intraoperative complications are affected by many factors, so the surgeons should be proficient in operating skills to avoid complications.
