The Temporal pathological changes of venous catheter-related fibrin sheath and their implications for nursing practice

FS rapidly forms and dynamically evolves during the ultra-early period after catheterization, leading to time-dependent exacerbation of mechanical obstruction, thrombosis, and vascular inflammatory injury. The study identifies 48-72 hours as a critical intervention window, recommending enhanced clinical assessment and timely intervention (e.g., optimizing catheter replacement timing) to reduce the risk of catheter-related complications.
