Romed venous catheters with valve and wings 22G, sterilized. They feature thin walls with high flow capacity, ensuring that there is no fluctuation in flow and that no mechanical irritation or thrombophlebitis occurs. The smooth surface and the special design of the tip and bevel ensure minimal injury during venipuncture, while the special "grasping" design allows for one-handed venipuncture. Additionally, they have flexible wings, a hydrophobic blood switch, a screw connection for luer-lock administration, and a removable cone for catheter protection. The color coding helps in recognizing sizes.

The insertion of a venous catheter is indicated for:

• Administration of intravenous therapy medications
• Administration of intravenous fluids-electrolytes
• Administration of parenteral nutrition
• Blood transfusion-products
• Administration of intravenous agents for diagnostic purposes

For the placement of the venous catheter, the following veins are selected:

• the dorsal surface of the hand
• the forearm
• the foot

The nurse is responsible for:

• the selection of an appropriate vein
• the adherence to standard aseptic-antiseptic principles during placement and care of the venous catheter
• maintaining the patency of the venous catheter
• proper care of the catheter to prevent complications
• managing complications

Basic principles in the placement of a venous catheter:

• Selecting the veins of the upper limb for the placement of the venous catheter.
• Selecting the size of the catheter based on the purpose, the duration of use, and the condition of the patient's venous network.
• Daily evaluation of the entry site of the venous catheter.
• Removal of the catheter if the patient shows signs of phlebitis or infection.
• Replacement of the catheter should not occur more frequently than every 72-96 hours.
• Smaller-sized venous catheters cause less irritation to the endothelium of the veins.
