Where to Insert an IV Cannula?

The preferred sites for IV cannula insertion are the cephalic or basilic veins in the nondominant arm, followed by the dorsal hand venous network.

Here's a more detailed look:

Selecting an IV Cannula Insertion Site

Before inserting an IV cannula, consider the following:

• Patient's Nondominant Arm: A venous tourniquet should be placed over the patient's nondominant arm to help visualize and distend the veins.

• Vein Preference: According to reference material, the veins of choice for catheterization include:

  • Cephalic Vein
  • Basilic Vein
  • Dorsal Hand Venous Network

Vein Selection Considerations

Choosing the appropriate vein is crucial for successful IV cannulation and patient comfort. Here's a table summarizing key factors:

Vein	Advantages	Disadvantages
Cephalic Vein	Often large and easily accessible.	Can be superficial and prone to rolling.
Basilic Vein	Relatively large; less prone to rolling than cephalic.	Located deeper; may be more difficult to access.
Dorsal Hand Venous Network	Readily visible; easy to access.	Smaller; more prone to infiltration.
