When a urinary catheter is not inserted using proper technique, becomes unclean, or remains in place for too long, microorganisms can travel through the catheter lumen or along the outside of the catheter and infect the bladder or kidneys, resulting in a catheter-associated urinary tract infection (CAUTI). Urinary tract infections resulting from catheter use are one of the most common health care-associated infections. The insertion of a urinary catheter is considered to be routine care. Improving practices of placement and removal of urinary catheters requires education aimed at changing the habits of nurses and physicians. Clinicians should follow evidence-based guidelines, including using aseptic technique for site preparation and supplies and limiting use and duration of the placement of urinary catheters. Perioperative personnel need to be aware of the risks of catheterization and take steps to prevent CAUTIs. This article discusses CAUTIs, including causes and strategies for prevention.
当导尿管未采用正确技术插入、变脏或留置时间过长时，微生物可通过导尿管管腔或沿导尿管外部移动并感染膀胱或肾脏，导致导尿管相关尿路感染（CAUTI）。因使用导尿管而引起的尿路感染是最常见的医疗保健相关感染之一。导尿管插入被视为常规护理。改善导尿管置入和拔除操作需要开展教育，以改变护士和医生的习惯。临床医生应遵循循证指南，包括对置管部位进行无菌技术准备和使用无菌用品，并限制导尿管的使用和留置时间。围手术期工作人员需要意识到导尿的风险并采取措施预防CAUTI。本文讨论了CAUTI，包括其病因和预防策略。
