摘要加速康复外科已在多个领域广泛应用，通过实施一系列围手术期优化措施，有效降低了医用导管的安置数量与留置时间。但在临床中，导管仍不可避免被大量使用，相关感染的风险持续存在。防止导管表面细菌黏附与生物膜形成至关重要。通过表面引入防污抗黏附、抑制或杀灭细菌的物质，形成抗菌功能表面，为解决导管相关感染提供了新的策略。本文总结了医用抗菌涂层导管的研究现状，介绍抗菌涂层的抗菌策略与原理，阐述其在临床应用中的实际效果，并分析未来研究方向。这些研究为减少导管相关感染，推动临床护理技术创新和提高护理质效提供了重要参考。

abstractsEnhanced recovery after surgery has reduced the number and duration of medical catheter placements through perioperative optimization measures. However, in clinical practice, catheters are still inevitably heavily used, and the risk of catheter-related infections persists. Preventing bacterial adhesion and biofilm formation on catheter surfaces is crucial. Medical antibacterial-coated catheters introduce substances that prevent fouling and adhesion, inhibit or kill bacteria on the surface, forming an antibacterial functional surface, providing a new strategy to address catheter-related infections. This article summarizes the current research status of medical antibacterial-coated catheters, introduces the antibacterial strategies and principles of the coatings, describes their actual effects in clinical applications, and analyzes future research directions. These studies help reduce catheter-related infections, promote innovation in clinical nursing technology, and improve the quality and efficiency of nursing care.
