摘　　要：目的分析胸部手术患者术后肺部感染状况,总结预防术后感染的对策,旨在降低肺部感染发生率。方法随机选取2011年1月-2013年4月医院胸心外科行胸部手术患者480例,对发生术后感染患者进行分析,其中包括:年龄、性别分布、是否有吸烟史、术前肺功能检查、手术出血量、手术时间、术后住院时间,数据采用SPSS18.0进行统计分析,计量资料采用t检验,计数资料采用χ2检验。结果 480例行胸部手术患者发生肺部感染83例,感染率17.29%;年龄≥60岁、有吸烟史、患有慢性疾病是发生肺部感染的相关因素(P<0.05);胸部手术患者的手术时间、术前肺功能检查气道阻塞肺量测定(FEV1/FVC)、手术出血量差异有统计学意义(P<0.05);平均住院时间(15.7±2.9)d,均治愈出院。结论年龄分布、是否有吸烟史、是否有慢性病、手术时间、术前肺功能检查、手术出血量是胸部手术患者发生肺部感染的相关因素,应采取有效的干预措施,以降低肺部感染发生率。OBJECTIVE To analyze the incidence of postoperative pulmonary infections in the patients undergoing chest surgery and put forward prevention countermeasures so as to reduce the incidence of pulmonary infections. METHODS A total of 480 cases of patients, who underwent chest surgery in cardiothoracic surgery department from Jan 2011 to Apr 2013, were enrolled in the study, then the related factors for the postoperative pulmonary infections including the age, gender, smoking history, preoperative pulmonary function examination, intraopera- tive bleeding volume, operation duration, and postoperative hospitalization duration were analyzed, the statistical analysis was performed with the use of SPSS18.0 software, the measurement data were analyzed by using the t-test, and the count data were analyzed with the use of chi-square test. RESULTS Of totally 480 cases of patients undergoing the chest surgery, the pulmonary infections occured in 83 cases with the infection rate of 17.29 %. The more than 60 years of age, smoking history, and chronic diseases were the related factors for the pulmonary infec- tions （P〈0.05）; the difference in the operation duration, preoperative pulmonary function examination airway obstruction spirometry （FEV1/FVC）, or the intraoperative bleeding volume was statistically significant （P〈0.05）. The mean hospitalization duration was （15. 7±2. 9）days, and all cases were cured and discharged. CONCLUSION The age, smoking history, chronic diseases, operation duration, preoperative pulmonary function examination, and intraoperative bledding volume are the related factors for the postoperative pulmonary infections, it is necessary to take effective intervention measures to reduce incidence of the pulmonary infections.
