普外科患者切口感染病原菌分布与相关因素分析

Related factors and bacteria distribution of incision infections of patients in general surgery department

目的研究普外科患者切口感染的相关因素及常见菌群分布,为预防治疗切口感染合理应用抗菌药物提供参考依据。方法选择2011年3月-2015年3月于普外科治疗的510例患者临床资料,搜集患者切口感染的相关因素,切口分泌物培养观察感染的菌群分布,数据采用SPSS 13.0软件进行统计分析。结果 510例患者中发生术后切口感染34例,感染率为6.67%;患者高龄、急性手术、合并糖尿病、结直肠部位手术、手术时间较长、Ⅱ类以上手术切口、术中出血量大是手术切口感染的相关因素(P<0.05);共检出25株病原菌,以革兰阴性菌为为主,共14株占56.00%。结论普外科切口感染的主要病原菌为革兰阴性菌,且发生感染的高危因素多,临床应予以重视。

OBJECTIVE To analyze the related factors and bacteria distribution of incision infections of patients in general surgical department. METHODS Totally 510 cases of patients in general surgery department were selected from Mar. 2011 to Mar. 2015, and the relevant factors of wound infections were collected and bacteria distribution of incision secretion was observed. All data were statistically analyzed by SPSS 13.0 software. RESULTS The re- sult showed that 34 cases appeared infections in 510 cases of patients, and the infection rate was 6.67%. And old age, acute surgery, basic diabetes, coloreetal surgery, long operative time, type Ⅱ or more severe surgical inci- sions, patients with large amount of bleeding were found to be risk factors for incision infections and the differ- ences were significant （P〈0.05）, Totally 25 strains of pathogens were detected, in which 14 strains of gram-neg- ative bacteria （56.00% ） accounted for the majority. CONCLUSION The main pathogenic bacteria of incision infec- tions in general surgery department were gram-negative bacteria, and risks factor for the infections are various. We should attach great importance on it in clinical practices.
