摘要

目的:探讨留置导尿患者尿路感染的病原微生物及其对常用抗生素的药敏模式。对象与方法:对2011年4月至2012年1月108例留置导尿患者进行研究。采用常规培养方法分离微生物,采用常规生化方法鉴定。采用Kirby-Bauer圆盘扩散法在Muller-Hinton琼脂上测定其药敏谱。结果:93例(86.1%)患者尿液微生物病原菌培养阳性。大肠杆菌(50.5%)是最常见的分离菌,其次是克雷伯菌(14%)和铜绿假单胞菌(10.8%)。常见革兰氏阴性菌的体外药敏模式对氨苄西林、阿莫西林+克拉维酸、氟喹诺酮类等常用抗生素均有较高耐药性。碳青霉烯类和阿米卡星是常见革兰氏阴性菌最有效的抗生素。结论:应重视良好的导尿管管理,而不是预防性使用抗生素治疗,以减少导尿管相关性尿路感染的发生。

A Study of Urinary Tract Infections in Patients with Catheter in Tertiary Care Hospital in Western Uttar Pradesh
Aim: The aim of this study was to determine microorganisms responsible for urinary tract infections (UTI) in patients with indwelling urinary catheter and their antibiotic susceptibility patterns to commonly used antibiotics. Subjects and Method: The study was carried out from April 2011 to January 2012 on 108 patients with indwelling urinary catheters. The organisms were isolated by conventional culture methods and identified by conventional biochemical methods. The antibiotic susceptibility pattern was determined by Kirby-Bauer disc diffusion method on Muller-Hinton agar. Results: In this study, 93 (86.1%) patients were found to be culture positive for microbial pathogens in their urine samples. Escherichia coli (50.5%) was the most frequently isolated bacteria followed by Klebsiella species (14%) and Pseudomonas aeruginosa (10.8%). The in-vitro susceptibility pattern of frequently isolated gram negative bacteria shows high resistance to commonly used antibiotics such as ampicillin, amoxicillin+clavulanic acid and fluoroquinolones. Carbapenems and amikacin were found to be the most effective antibiotics for frequently isolated gram negative bacteria. Conclusion: Emphasis should be placed on good catheter management rather than using prophylactic antibiotic therapy to reduce the incidence of catheter associated urinary tract infection.
