Study Notes
IV Cannulation Recommendations
- Using a smaller gauge of catheter for IV cannulation is recommended when possible to minimize tissue damage and promote patient comfort.
Purpose of IV Cannulation
- The primary purpose of intravenous (IV) cannulation is to administer medications, fluids, and other therapies directly into the bloodstream.
Choosing the Right Catheter Size
- A larger-gauge catheter is recommended in massive trauma situations where high-volume fluid resuscitation is required.
- The choice of cannula size depends on the patient's vein size, with smaller veins requiring smaller needles.
Considerations for IV Therapy
- For prolonged IV therapy, it is recommended to use the patient's non-dominant arm to minimize disruption to daily activities.
Vein Visualization Techniques
- Holding the patient's arm down can help highlight the vein and make it more visible for cannulation.
- Applying a tourniquet around the patient's arm can also help to make the vein more prominent, but it should be done just before attempting cannulation.
Cannula Insertion and Flashback
- After achieving flashback during cannula insertion, the needle should be advanced further into the vein to ensure proper placement.
Troubleshooting Vein Access
- If difficulty is encountered in finding a good vein on one arm, the other arm should be attempted to ensure successful IV cannulation.

Description
Test your knowledge on the technique of intravenous (IV) cannulation, which involves placing a catheter or cannula inside a vein to provide venous access for sampling blood and administering fluids, medications, and blood products.
