katetrar

Katetrar is a family of flexible tubular devices introduced into the body to drain fluids, administer substances, or provide access for diagnostic or therapeutic procedures. Catheters are used across medical specialties and vary by site of access, purpose, size, and material.

The word katetrar derives from the Greek katheteros, via Latin catheter, meaning to bring or let down into a vessel. Early catheters date to ancient civilizations, with wooden, metal, or reed tubes; modern catheters are primarily made from latex, silicone, or polyurethane and designed for single-use or extended access.

Common categories include urinary catheters (such as Foley and intermittent-type), intravascular catheters (peripheral IV, midline, central venous catheters, and peripherally inserted central catheters), arterial catheters, feeding catheters, and diagnostic catheters used in imaging procedures. Catheters differ in size (French scale), coatings, and flexibility.

They enable urinary drainage, vascular access for fluids and medications, hemodynamic monitoring, contrast administration for imaging, and targeted therapy within cavities or body spaces.

Insertion and maintenance require sterile technique and trained personnel. Complications include infection, thrombosis, occlusion, dislodgement, and tissue injury. Regular assessment, securement, and timely removal are important for minimizing risks.
