研究目的:

主要目的是探索尿道外口酸性环境对预防导尿管相关尿路感染(CAUTI)的临床效果;其次将系统评估"酸性溶液冲洗+酸性凝胶涂抹"方案对局部微环境(pH值和微生物含量)的具体影响;最终目标是为临床制定基于循证医学的非消毒剂预防策略提供可靠依据,推动指南更新和护理实践优化。  

Objectives of Study:

The primary objective is to investigate the clinical efficacy of maintaining an acidic urethral meatus environment in preventing catheter-associated urinary tract infections (CAUTIs). Secondly, the study will systematically evaluate the specific effects of the "acidic solution irrigation + acidic gel application" protocol on the local microenvironment (including pH levels and microbial load). The ultimate goal is to provide robust evidence for establishing a non-disinfectant, evidence-based prevention strategy in clinical practice, thereby contributing to guideline updates and the optimization of nursing protocols.
