IV Cannulation Insertion Images

IV cannulation is a medical procedure that involves the insertion of a thin tube called a catheter into a vein to administer fluids, medication, or obtain blood samples. It is a common procedure performed in hospitals and healthcare settings. In this blog post, we will explore the process of IV cannulation insertion, and provide a visual guide with relevant images.

Introduction to IV Cannulation

IV cannulation is a vital skill for healthcare professionals, especially nurses and doctors. It allows for the administration of fluids and medications directly into the bloodstream, which can be crucial in emergency situations or when patients are unable to take medications orally.

Step-by-step Guide: IV Cannulation Insertion

Before initiating the IV cannulation procedure, it is important to gather the necessary equipment, including sterile gloves, antiseptic solution, tourniquet, IV catheter, and securement device.

  1. Begin by properly identifying the patient and explaining the procedure to them.
  2. Ensure proper hand hygiene by washing your hands or using an alcohol-based sanitizer.
  3. Select an appropriate vein for cannulation, typically in the upper extremities.
  4. Apply a tourniquet above the chosen site to engorge the vein and make it easier to locate.
  5. Cleanse the site with an antiseptic solution and allow it to dry.
  6. Put on sterile gloves to maintain aseptic technique.
  7. Insert the IV catheter into the vein at a 15-30 degree angle, with the bevel facing up.
  8. Once flashbacks of blood are seen in the catheter, advance it slightly further and remove the needle.
  9. Secure the catheter in place with an appropriate securement device.
  10. Connect the IV tubing or extension set to the catheter hub.
  11. Flush the catheter to ensure proper placement and patency.

Common Challenges and Troubleshooting

During the IV cannulation procedure, healthcare professionals may encounter various challenges, such as difficult vein access, vein rolling, or infiltration. It is crucial to be aware of these issues and have appropriate strategies to overcome them. Here are some common troubleshooting techniques:

  • If the vein is difficult to access, try using a smaller gauge catheter or using a different site.
  • If the vein starts to roll, stabilize it by applying gentle pressure below the site with your non-dominant hand.
  • If infiltration occurs, stop the infusion immediately, remove the catheter, and apply a warm compress.


IV cannulation insertion is a fundamental medical procedure used for administering medications and fluids directly into the bloodstream. It is essential for healthcare professionals to master this skill to ensure safe and effective patient care. By following proper techniques and utilizing visual guides, professionals can perform IV cannulation with confidence and minimize complications.
