【摘要】：目的探讨高危因素及病原菌分布,旨在为降低高危因素、选取敏感抗菌药物以控制感染提供依据。方法选取2014年2月-2016年3月经尿道膀胱肿瘤切除术者324例,引入多因素logistic回归模型分析经尿道膀胱肿瘤切除患者术后尿路感染的高危因素,并观察尿路感染者的病原菌分布特点。结果 324例经尿道膀胱肿瘤切除患者术后尿路感染48例,感染率14.81%;年龄≥65岁、糖尿病、高血压、肿瘤位点(多发)、术前导尿、手术时间≥90min、导尿管留置≥7d、膀胱冲洗时间≥2d患者尿路感染率高,差异有统计学意义(P0.05);引入二分类logistic回归模型,筛查出年龄≥65岁、糖尿病、肿瘤位点(多发)、术前导尿、手术时间≥90min、导尿管留置≥7d、膀胱冲洗时间≥2d是经尿道膀胱肿瘤切除术后尿路感染的独立危险因素;且尿路感染者检出革兰阴性菌39株占70.91%,革兰阳性菌15株占27.27%,真菌1株占1.82%,革兰阴性菌构成比高于其他类型,且大肠埃希菌、肺炎克雷伯菌构成比高于其他病原菌。结论年龄、糖尿病、肿瘤位点、术前导尿、手术时间、导尿管留置、膀胱冲洗时间是本地区经尿道膀胱肿瘤切除术后尿路感染的高危因素,且以革兰阴性菌为主,所以早期采用有效防控措施,正确选取敏感抗菌药物,有助于控制术后尿路感染率、促进患者早日康复。
[Abstract]:Objective to study the high risk factors and the distribution of pathogenic bacteria in order to reduce the high risk factors and select sensitive antibiotics to control infection. Methods from February 2014 to March 2016, 324 cases of urethral bladder tumor resection were selected, and multivariate logistic regression model was used to analyze the risk factors of urinary tract infection after transurethral resection of bladder tumor. The distribution of pathogenic bacteria in patients with urinary tract infection was observed. Results the infection rate was 14.81% in 324 patients with urinary tract infection after transurethral resection of bladder tumor. Age 鈮，
