Maintain patency of indwelling intravenous catheter

The phrase "maintain patency of indwelling intravenous catheter" refers to a procedural and preventive indication rather than an intrinsic disease entity Without proactive maintenance, indwelling vascular devices are vulnerable to mechanical, chemical, and thrombotic occlusion caused by intraluminal blood reflux, platelet aggregation, fibrin sheath formation, or drug precipitation

It describes the ongoing clinical preservation of lumen openness and functional fluid flow in vascular access devices—including peripheral intravenous lines, peripherally inserted central catheters, and central venous lines—placed across pediatric and adult patient populations

It describes the ongoing clinical preservation of lumen openness and functional fluid flow in vascular access devices—including peripheral intravenous lines, peripherally inserted central catheters, and central venous lines—placed across pediatric and adult patient populations Preserving catheter patency prevents interrupted intravenous therapies, device failure, repetitive venipunctures, and secondary vascular complications such as catheter-related bloodstream infections or thromboembolism
