IV Cannula Insertion Procedure

Are you preparing for a career in healthcare or expanding your medical knowledge? Understanding the procedure for inserting an intravenous (IV) cannula is crucial. In this blog post, we will guide you through the step-by-step process of safely and efficiently inserting an IV cannula.

Step 1: Prepare Yourself and the Patient

Prior to starting the procedure, gather all the necessary supplies. Ensure you have clean gloves, an IV cannula of the appropriate size, sterile dressing, antiseptic solution, transparent tape, and intravenous solution. Verify the patient’s identity and explain the procedure to them, addressing any concerns or questions they may have.

Step 2: Perform Hand Hygiene

Wash your hands thoroughly with soap and water for at least 20 seconds. Dry your hands with a clean towel or use a hand sanitizer with at least 60% alcohol content.

Step 3: Choose the Appropriate Vein

Assess the patient’s veins to determine the best site for cannulation. Look for easily accessible, visible, and palpable veins. Common sites for IV cannulation include the forearm, dorsum of the hand, and antecubital fossa.

Step 4: Apply a Tourniquet

Place a tourniquet about 10-15 cm above the intended cannulation site. This will help engorge the veins, making them more prominent and easier to access.

Step 5: Cleanse the Site

Using an antiseptic solution such as chlorhexidine or iodine, clean the selected site in a circular motion, starting from the center and moving outward. Allow the site to air dry or use sterile gauze to pat it dry.

Step 6: Prepare the Cannula

Open the packaging of the IV cannula and attach it to the extension set or IV tubing. Ensure the cannula is intact and the needle guard is securely in place.

Step 7: Stabilize the Vein

Apply gentle traction on the skin distal to the intended insertion site to stabilize the vein and minimize its movement during cannulation.

Step 8: Insert the Cannula

Hold the cannula at a 20-30 degree angle with the bevel facing upward. Stabilize the vein with your nondominant hand and gently advance the cannula into the vein using a smooth, swift motion.

Step 9: Secure the Cannula

Once the cannula is successfully inserted into the vein, advance it a little further and withdraw the stylet. Apply gentle pressure with a sterile gauze pad to the insertion site while removing the needle entirely. Then, attach the hub of the cannula to the extension set.

Step 10: Secure and Dress the Site

Using transparent tape, secure the cannula and extension set to the patient’s skin. Apply a sterile dressing over the site to protect it from contamination and potential infection.

Step 11: Connect IV Tubing

Connect the IV tubing or extension set to the hub of the cannula and ensure all connections are secure.

Step 12: Document the Procedure

Record the date, time, site of cannulation, size of the cannula, patient’s tolerance, and any observed complications or abnormalities in the patient’s medical record.

Remember, practice and experience are key to becoming proficient at IV cannula insertion. Regularly update your knowledge and skills by referring to reputable sources and seeking guidance from experienced healthcare professionals.
