kathetersystemen

Kathetersystemen, or catheter systems, are assemblies of catheters and related components designed to access the body’s internal spaces for drainage, administration of fluids and medications, or monitoring of physiological parameters. They are used in a wide range of medical settings, including emergency care, surgical suites, and intensive care units.

Common categories include peripheral intravenous catheter systems for venous access, central venous catheter systems for large-bore access and monitoring, urinary catheter systems for urinary drainage, and arterial catheter systems for invasive blood pressure monitoring and sampling. Each type serves specific clinical goals and requires appropriate insertion techniques, maintenance, and removal procedures.

A catheter system typically comprises a flexible catheter tube, hubs or connectors, valves or stopcocks, infusion sets, drainage bags where applicable, and fixation devices or dressings to secure the catheter and protect the insertion site. Materials commonly used include polyurethane or silicone; latex is less common due to allergy considerations. Some specialty catheters or accessories incorporate coatings or features to reduce friction or infection risk.

Uses of catheter systems include administration of fluids, medications, and parenteral nutrition; collection of blood samples; drainage of urine or other fluids; and invasive monitoring of hemodynamic status. They enable continuous or intermittent therapy and rapid access in clinical care.

Safety and infection prevention are central concerns. Proper insertion technique, aseptic care, regular inspection for signs of complications, timely removal when no longer needed, and adherence to clinical guidelines help minimize risks such as catheter-associated infections, occlusion, dislodgement, and thrombosis. Guidelines from health authorities guide best practices in insertion, maintenance, and removal.
