【摘要】：目的探討高危因素及病原菌分布,旨在為降低高危因素、選取敏感抗菌藥物以控制感染提供依據(jù)。方法選取2014年2月-2016年3月經(jīng)尿道膀胱腫瘤切除術者324例,引入多因素logistic回歸模型分析經(jīng)尿道膀胱腫瘤切除患者術后尿路感染的高危因素,并觀察尿路感染者的病原菌分布特點。結果 324例經(jīng)尿道膀胱腫瘤切除患者術后尿路感染48例,感染率14.81%;年齡≥65歲、糖尿病、高血壓、腫瘤位點(多發(fā))、術前導尿、手術時間≥90min、導尿管留置≥7d、膀胱沖洗時間≥2d患者尿路感染率高,差異有統(tǒng)計學意義(P0.05);引入二分類logistic回歸模型,篩查出年齡≥65歲、糖尿病、腫瘤位點(多發(fā))、術前導尿、手術時間≥90min、導尿管留置≥7d、膀胱沖洗時間≥2d是經(jīng)尿道膀胱腫瘤切除術后尿路感染的獨立危險因素;且尿路感染者檢出革蘭陰性菌39株占70.91%,革蘭陽性菌15株占27.27%,真菌1株占1.82%,革蘭陰性菌構成比高于其他類型,且大腸埃希菌、肺炎克雷伯菌構成比高于其他病原菌。結論年齡、糖尿病、腫瘤位點、術前導尿、手術時間、導尿管留置、膀胱沖洗時間是本地區(qū)經(jīng)尿道膀胱腫瘤切除術后尿路感染的高危因素,且以革蘭陰性菌為主,所以早期采用有效防控措施,正確選取敏感抗菌藥物,有助于控制術后尿路感染率、促進患者早日康復。
[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，
