Objective To investigate risk factors of postoperative nosocomial pneumonia in patients after lung cancer surgery, and propose corresponding preventive measures. Methods We retrospectively analyzed clinical records of 720 patients who underwent surgical resection for lung cancer in the First Affiliated Hospital of Xinjiang Medical University between June 2003 and June 2012. There were 460 males and 260 females with their average age of 60.37(17 to 83) years. Univariate analysis and multivariate non-conditional logistic regression analysis were performed to investigate independent risk factors of postoperative nosocomial pneumonia in patients after lung cancer surgery. Results Univariate analysis showed that postoperative nosocomial pneumonia was related to 9 risk factors:age eld than 60 years (χ2=26.67, P=0.000), diabetes mellitus (DM, χ2=34.46, P=0.000), chronic obstructive pulmonary disease (COPD, χ2=59.30, P=0.000), long-term history of heavy smoking (χ2=10.40, P=0.001), duration of antacid therapy (χ2=7.69, P=0.006), operation time (χ2=38.12, P=0.000), surgical strategy (χ2=4.22, P=0.040), duration of mechanical ventilation (χ2=21.86, P=0.000), and significant incision pain (χ2=19.69, P=0.000), while preoperative lung function, antibiotic prophylaxis and intraoperative blood loss were not related to postoperative nosocomial pneumonia.Multivariate analysis showed that 8 factors were independent risk factors of postoperative nosocomial pneumonia including age eld than 60 years (χ2=5.43, P=0.020), DM(χ2=8.61, P=0.003), COPD (χ2=9.15, P=0.002), long-term history of heavy smoking (χ2=5.48, P=0.019), long-term antacid therapy (χ2=13.21, P=0.000), operation time (χ2=5.36, P=0.021), duration of mechanical ventilation (χ2=5.72, P=0.017), and significant incision pain(χ2=3.87, P=0.049). Conclusion Patients after lung cancer surgery are susceptible to postoperative nosocomial pneumonia. Proper preventive measures targeting at the characteristics and risk factors of lung cancer patients may reduce the incidence of postoperative nosocomial pneumonia.
The high incidence of hydatid disease in seven northwestern provinces, is one of the reason of "Poverty due to illness, and return poverty due to illness" in China. The incidence of chest hydatid disease in China after hepatic hydatid disease ranks second. Department of thoracic surgery in the First Affiliated Hospital of Xinjiang Medical University is on the domestic leading position of the treatment of chest hydatid disease. Since 1956 the first case of pulmonary hydatid cyst were completed, we have successfully finished the surgical treatment of pediatric chest hydatid disease, chest hydatid disease complex, huge pulmonary hydatid cyst, mediastinal and pleural hydatid cyst, and rib hydatid in our department. To further standardize the treatment of chest hydatid disease, a special formulation of "technical specification for chest hydatid disease diagnosis expert consensus" by our department were produced, in order to help clinicians treat chest hydatid disease by more suitable strategies. This consensus was released in July 2015, for the original version. The definition, diagnosis, treatment principle, and prevention of chest hydatid disease were elaborated and clinical experiences of 60 years were combined with in this consensus, in order to help the clinicians for diagnosis, treatment, and prevention of hydatid disease.
