开胸术后患者发生胸腔感染的高危因素调查分析

The analysis of the high-risk factors for patients with pleural infection after thoracotomy

目的分析开胸术后患者发生胸腔感染的高危险因素,为制定合理的预防措施提供参考依据。方法对我院自2010年2月至2011年12月行开胸术的患者102例进行回顾性分析,对患者的年龄、术前肺功能、手术时间、手术类型、胸管留置时间、胸管类型等进行统计分析,同时对患者的胸腔引流管前端进行细菌培养。结果 102例开胸术后患者胸腔感染率为13.73%(14/102),其中手术时间、肺功能、术后污染、胸管留置时间与胸腔感染具有相关性(P<0.05);与年龄、性别、胸管类型及抗生素的应用种类等因素无关(P>0.05);其中感染病原菌主要以铜绿假单胞菌为主。结论开胸术后患者胸腔感染主要与手术时间、肺功能、术后环境、胸管留置时间具有相关性,因此应采取对应措施,有效地降低患者的胸腔感染率,可提高患者的生存质量。

Objective To analyze the high-risk factors for patients with pleural infection after thoracotomy and provide a reference for reasonable precautions. Methods From February 2010 to December 2011,102 patients with thoracotomy in our hospital were retrospectively analyzed. Age,pulmonary function before surgery, operative time, type of surgery, chest tube indwelling time and type were taken for statistical analysis. Bacterial cultures were taken at the front-end of the chest tubes. Results In 102 cases, pleural infection rate was 13.73% （14/102）. Operative time, lung function after surgery, chest tube indwelling time were related with pleural infection（P〈0. 05）. It had no relationship with age gender,chest tube type and the application of antibiotics kinds of factors（P〉0. 05）. The main infection pathogen was Pseudomonas aeruginosa. Conclusion Pleural infection after thoracotomy is mainly related with the time of the surgery,lung function,postoperative environment and chest tube time. Therefore we should take corresponding measures to reduce the infection rate effectively,and improve the patient＇s quality of life.
