经尿道保留导尿患者采用密闭引流系统是最有效控制医院内泌尿道感染的方法,在美国广为使用。但是,一方面由于导尿患者大部分具有危险因素,另方面引流系统常发生故障,因此,导尿并发泌尿道感染仍占医院内所有感染的30％以上。作者近来研究发现导管与尿道间的粘膜鞘是密闭引流时细菌进入膀胱的主要途径,尿道潜在致病菌的移植是引起菌尿的主要危险。为减少尿道细菌和阻断细菌进入途径,作者采用目前广为推荐的尿道护理两
Transurethral catheterization of patients with closed drainage system is the most effective control of urinary tract infections in hospitals, widely used in the United States. However, on the one hand, most of the catheterization patients have risk factors, and on the other hand, the drainage system often fails. Therefore, catheterization and urinary tract infections still account for more than 30% of all hospital infections. The authors recently found that the mucosal sheath between the catheter and the urethra is the main way for bacteria to enter the bladder during closed drainage. The potential risk of bacteriuria is the transplantation of potential pathogens in the urethra. To reduce the urethral bacteria and block the bacteria into the pathway, the author uses the currently widely recommended urethral care two
