IV Cannula Procedure Steps

Inserting an intravenous (IV) cannula is a common medical procedure performed to administer fluids, medications, or blood products directly into a patient’s bloodstream. This blog post will provide a detailed step-by-step guide on how to perform the IV cannula procedure.

Step 1: Prepare the Equipment

The first step in the IV cannula procedure is to gather all the necessary equipment. This includes an IV cannula, alcohol swabs, a tourniquet, adhesive tape, a transparent dressing, a syringe, and the prescribed IV solution or medication.

Step 2: Assess the Patient

Before starting the procedure, it is crucial to assess the patient’s veins to determine the most suitable insertion site. Look for visible, accessible veins in the patient’s arm or hand. Choose a site that is free from any inflammation, infection, or edema.

Step 3: Hand Hygiene

Prior to the procedure, perform hand hygiene following the recommended guidelines. This involves washing your hands with soap and water or using an alcohol-based hand sanitizer.

Step 4: Position the Patient

Position the patient’s arm in a comfortable and extended position, exposing the selected insertion site. Place a small pillow or rolled towel under the patient’s wrist for support.

Step 5: Apply Tourniquet

Apply a tourniquet a few inches above the intended insertion site. Ensure it is tight enough to obstruct venous blood flow but loose enough to allow arterial blood flow.

Step 6: Prepare the Cannula

Open the IV cannula package, ensuring sterile conditions are maintained. Attach the cannula to the syringe and draw back the plunger to check for blood return, ensuring the needle is properly placed within the cannula.

Step 7: Cleanse the Skin

Using an alcohol swab, cleanse the selected insertion site in a circular motion, starting from the center and moving outward. Allow the area to dry completely before proceeding.

Step 8: Insert the Cannula

Hold the cannula like a pencil, with the bevel up, and at a shallow angle of approximately 15 degrees to the skin. Insert the cannula into the vein with a smooth and confident motion, using a controlled puncture.

Step 9: Confirm Cannula Placement

Once the cannula is inserted, gently advance it further into the vein while stabilizing the catheter. Observe for a flash of blood in the flashback chamber of the cannula, indicating successful placement.

Step 10: Secure the Cannula

Once the cannula is in place, remove the tourniquet and gently advance the cannula further into the vein. Secure it in place using adhesive tape, ensuring it is stabilized and not causing discomfort to the patient.

Step 11: Dress the Site

Use a transparent dressing to cover the insertion site, ensuring the entire area is adequately covered. This helps maintain sterility and allows easy monitoring of the site for any signs of complications.

Step 12: Check for Proper Functioning

Connect the IV tubing or syringe to the cannula hub and ensure proper flow of fluids. Observe for any signs of infiltration, phlebitis, or other complications. Document the procedure and monitor the patient regularly.

By following these step-by-step instructions, healthcare professionals can confidently perform the IV cannula procedure, ensuring patient safety and comfort throughout the process.
