| 摘要 目的：分析胸外科患者术后医院感染的病原菌分布及危险因素，为防控医院感染提供数据支持。方法：选择2014年1月至2015年5月医院接受胸外科手术治疗的患者284例进行研究。回顾性分析284例患者的临床病历数据资料以及细菌培养与鉴定的结果，分析医院感染的主要部位及病原菌分布，以及产生医院感染的危险因素。结果：284例患者共有82例发生医院感染，感染率是28.87%， 感染部位以呼吸系统为主，占56.10%；检出病原菌88株，革兰阴性菌71株，占80.68%，以铜绿假单胞菌为主，占30.68%。革兰阳性菌17株，占19.32%，以金葡菌为主，占9.09%。单因素分析发现，胸外科术后医院感染与年龄、手术时间、住院时间及糖尿病史有关，差异有统计学意义（P<0.05）；Logistic回归分析显示，年龄≥60岁、手术时间＞2 h、住院时间＞15 d以及有糖尿病史是胸外科术后医院感染的危险因素。结论：胸外科患者术后医院感染的病原菌分布以铜绿假单胞菌与金葡菌为主，应重点防范影响感染的危险因素，以降低感染率。 |

| ABSTRACT Objective: To study pathogenic distribution and risk factors analysis of nosocomial infection in patients after thoracic surgery, to provide data support for the prevention and control of hospital infection. Methods: Selected 284 cases of thoracic surgery treatment of patients from January 2014 to May 2015 in hospital. Retrospective analysis of the clinical data of 284 cases of patients with bacterial culture and identification of the results, analysis of the main part of hospital infection and the distribution of pathogenic, as well as the risk factors of hospital infection. Results: A total of 284 patients with 82 cases of nosocomial infection,infection rate was 28.87%, the infection site to respiratory system, accounting for 56.10%; 88 strains of pathogenic, in which gram negative bacteria had 71 strains, accounting for 80.68%, mainly was pseudomonas aeruginosa,accounting for 30.68%. Gram positive bacteria had 17 strains, accounting for 19.32%, mainly was Staphylococcus aureus, accounting for 9.09%. Single factor analysis showed that the infection of hospital infec- tion was related to age, operation time, hospitalization time and history of diabetes,difference was statistically significant(P<0.05); Logis- tic regression analysis showed that age≥60 years, operation time>2 h, hospitalization time>15 days and a history of diabetes were the risk factors in patients with thoracic surgery after produce hospital infection. Conclusion: The distribution of pathogenic bacteria of noso- comial infection in patients after thoracic surgery was mainly caused by Pseudomonas aeruginosa and Staphylococcus aureus, we should focus on the prevention of infection risk factors to reduce the infection rate. |
