Removal of Peripheral IV Cannula

Peripheral Intravenous (IV) cannulation is a common medical procedure performed to administer fluids, medication, or blood products directly into a patient’s vein. However, there comes a time when the IV cannula needs to be removed. In this blog post, we will discuss the importance of proper removal techniques for peripheral IV cannulas and the associated considerations.

When to Remove an IV Cannula

Knowing when to remove an IV cannula is crucial to prevent complications and ensure patient well-being. The following situations may warrant the removal of an IV cannula:

  • The prescribed infusion is completed
  • The patient experiences pain or discomfort at the insertion site
  • The IV catheter becomes dislodged or damaged
  • The site shows signs of infection or phlebitis
  • The healthcare professional suspects a bloodstream infection

Removal Technique

To remove an IV cannula correctly, healthcare professionals should follow these steps:

  1. Gather the necessary supplies, such as gloves, sterile gauze, adhesive tape, and a transparent dressing.
  2. Explain the procedure to the patient and ensure their comfort.
  3. Perform hand hygiene and don gloves to maintain aseptic technique.
  4. Inspect the insertion site for any signs of complications, such as redness, swelling, or discharge.
  5. Gently stabilize the patient’s limb and ask them to remain still during the cannula removal.
  6. Apply a firm, steady pressure just below the insertion site while simultaneously withdrawing the cannula. This prevents blood from leaking out and decreases the risk of hematoma formation.
  7. Once the cannula is fully removed, hold sterile gauze over the site and apply gentle pressure to promote hemostasis.
  8. Assess the patient for any immediate complications and provide appropriate wound care instructions.

Considerations and Potential Complications

While removing an IV cannula is generally a straightforward process, there are a few important considerations and potential complications to keep in mind:

  • Some patients may experience mild discomfort or bleeding during removal, so closely monitor their response and address any issues immediately.
  • If resistance is encountered during cannula withdrawal, do not force removal. Consult a healthcare professional for assistance, as there may be an underlying issue.
  • Proper disposal of the used cannula and sharps is crucial to prevent injuries and potential transmission of bloodborne pathogens.
  • Thoroughly document the removal procedure, including the date, time, reason for removal, and any complications encountered. This information is vital for continuity of care.
  • Educate the patient on signs of complications post-removal, such as persistent bleeding, worsening pain, or unusual swelling, and advise them to seek medical attention if needed.


In conclusion, the removal of peripheral IV cannulas is an essential skill for healthcare professionals, ensuring patient safety and minimizing potential complications. By following proper removal techniques, being aware of associated considerations, and providing appropriate patient education, healthcare providers can ensure a smooth and effective IV cannula removal process.
