What are two techniques for arterial placement?

Radial artery cannulation (catheter over needle). Catheter introduction through skin. Femoral artery cannulation (catheter over needle). Insertion of 20-gauge, 1.75-in.

Why cannula is not inserted in artery?

Using an IV cannula with an injection port as an arterial line can lead to inadvertent injection of medications through the injection port in the artery with serious sequelae.

Is an arterial line the same as an IV?

An arterial line is a small catheter, similar to an intravenous, that is inserted into an artery (Image 1). is the most common placement. Arteries carry oxygen rich blood to all of the organs and tissues of the body. Arteries also have the highest pressure of all of the blood vessels.

What is arterial cannulation?

What is cannulation used for?

Intravenous (IV) cannulation is a technique in which a cannula is placed inside a vein to provide venous access. Venous access allows sampling of blood, as well as administration of fluids, medications, parenteral nutrition, chemotherapy, and blood products.

What is intra-arterial line?

Intra-arterial catheters (also called arterial cannulas or A-lines) are often inserted for invasive blood pressure (BP) monitoring and intravascular access for blood sampling in high-risk surgical and critically ill patients.

Which veins can be used for cannulation?

Cannulation of the cephalic, basilic, or other unnamed veins of the forearm is preferrable. The three main veins of the antecubital fossa (the cephalic, basilic, and median cubital) are frequently used. These veins are usually large, easy to find, and accomodating of larger IV catheters.

What is radial artery cannulation?

An indwelling arterial catheter allows for continuous blood pressure monitoring, frequent blood sampling, and arterial blood gas measurement. The radial artery is chosen for cannulation primarily because of the superficial nature of the vessel and ease of maintenance of the site.
