目的了解妇产科留置导尿病人医院感染情况,以便采取有效预防措施。方法采用临床观察和尿样细菌培养,对住院患者留置尿管与尿路感染情况进行了调查。结果在1 648例留置尿管患者中发生尿路感染158例,感染率为9.5%。尿管留置时间1～5 d,尿路感染率由5.68%增加到43.18%,其中22例患者重复导尿留置尿管,尿路感染率达到100%。158例尿路感染中有128例细菌培养为阳性,80%为革兰阴性杆菌,以大肠杆菌为主。结论留置导尿是引起泌尿道感染的主要因素,随导尿管留置时间延长感染率增加。
Objective To understand the hospital infection of obstetrics and gynecology catheterization in order to take effective preventive measures. Methods Clinical observation and urine culture were used to investigate the catheterization and urinary tract infection in hospitalized patients. Results Of the 1 648 indwelling catheter patients, 158 cases of urinary tract infection occurred, with an infection rate of 9.5%. The urinary tract infection rate increased from 5.68% to 43.18% 1 to 5 days after catheter placement, of which 22 cases had catheterization catheterization repeatedly, and the urinary tract infection rate reached 100%. Of the 158 urinary tract infections, 128 were positive for bacterial culture and 80% were Gram-negative bacilli, predominantly E. coli. Conclusion Indwelling catheterization is the main factor causing urinary tract infection, and the infection rate increases with the prolongation of urinary catheter retention time.
