Relevant Peripheral IV Cannula Should be Restarted

In medical settings, peripheral intravenous (IV) cannulation is a common procedure used to administer fluids, medications, or blood products directly into a patient’s veins. However, sometimes the IV cannula becomes dislodged or blocked, necessitating its reinsertion or restarting. This blog post will discuss the importance of restarting a relevant peripheral IV cannula and the steps involved in the process.

Why Restarting a Relevant Peripheral IV Cannula is Necessary

When an IV cannula becomes dislodged or blocked, it can lead to various complications. These complications may include infiltration, extravasation, phlebitis, or compromised medication administration. Restarting a relevant peripheral IV cannula helps mitigate these risks and ensures optimal patient care.

The Process of Restarting a Relevant Peripheral IV Cannula

1. Assess the need for restarting: Before initiating the restart procedure, healthcare professionals must evaluate the patient’s condition and the necessity of continuing IV therapy.

2. Gather necessary equipment: Ensure you have appropriate-sized IV cannulas, sterile gloves, antiseptic solution, dressings, and, if needed, local anesthesia.

3. Prepare the patient and the site: Explain the procedure to the patient, obtain consent, and select an appropriate site for cannulation. Cleanse the site with an antiseptic solution and allow it to dry.

4. Administer local anesthesia (if required): If the patient experiences discomfort during cannulation, local anesthesia may be administered to numb the area, thus improving patient comfort.

5. Insert the new IV cannula: Using aseptic technique, carefully insert the cannula into the vein, ensuring proper blood flashback. Secure the cannula in place, following institutional guidelines.

6. Flush and connect: Flush the cannula with saline to clear any blockages and verify proper functioning. Then, connect the administration set to begin delivering fluids or medications.

7. Monitor and document: Regularly assess the cannula site for signs of complications, such as swelling, redness, or pain. Document the procedure, including the size of the cannula, date, and time of insertion.

Best Practices for Restarting a Relevant Peripheral IV Cannula

– Follow aseptic technique throughout the procedure to minimize the risk of infection.

– Ensure proper hand hygiene before and after the procedure.

– Involve the patient in the decision-making process and provide education regarding care and maintenance of the IV cannula.

– Choose an appropriate-sized cannula based on the patient’s age, medical condition, and prescribed therapy.

– Regularly assess the cannula site for any signs of complications or infection.


In summary, restarting a relevant peripheral IV cannula is crucial to maintain patient safety and prevent complications associated with the dislodgement or blockage of the cannula. Through careful assessment, meticulous technique, and adherence to best practices, healthcare professionals can ensure successful IV therapy and improve patient outcomes.
