Are you teaching intravenous (IV) insertion, maintenance, and treatment to medical, nursing, or paramedic students? IV therapy is a common medical procedure that involves administering medications, fluids, and nutrients directly into a patient’s vein through the bloodstream. By injecting these substances into the bloodstream, they can spread quickly throughout the body to achieve the necessary treatment objective.

Practicing IV Therapy for Students

All students studying nursing or other forms of medicine will need to develop and practice IV skills. Inserting an IV line into a patient requires precision, patience, a deep understanding of human anatomy, and excellent hand-eye coordination. Even a minor mistake during the IV insertion process can have severe negative effects on the patient.

For this reason, students practicing their IV skills will practice on a mannequin arm rather than a real human patient’s arm. A mannequin arm is a lifelike arm resembling a human arm, but it is made of synthetic material. There are different types of simulated low-fidelity and high-fidelity mannequin arms available. The best ones will feature realistic anatomy, including veins and a backflow of artificial blood.

The Benefits of Practicing IV Therapy with a Mannequin Arm

Why is it better for students to use a mannequin arm than a human arm to practice IV skills? Will it provide them with the proper learning experience they need to work with IV lines in a real clinical setting?

Here are the top benefits of practicing IV skills with a mannequin arm:

1) Risk-Free IV Education

Mannequin arms create a 100% risk-free learning experience for students. There is no risk of injuring anyone because the mannequin arm is fake and does not belong to anyone. This will give students the confidence they need to focus on developing their IV skills without worrying about harming their patients.

2) Realistic Simulation

A high-quality mannequin arm will act just like a human arm. For instance, students can palpate the vein beneath the skin’s surface to identify the best location to insert the IV line. Then, when the needle enters the vein in the mannequin arm, it will send a backflow of artificial blood, indicating a successful insertion. This is similar to what happens in a real-life situation, where actual blood flows out after inserting the needle into a vein.

3) Easy for Repetition IV Training

Practicing IV skills on human patients is not only risky but also often comes with limited practice opportunities. Students must rely on repetition to continuously practice their IV skills, as it enables them to improve their skills further. A mannequin arm is perfect for repetition IV training because students can practice their IV skills as often as they want without inconveniencing anyone.

4) Builds Confidence

Students build confidence as they strengthen their IV skills by practicing on a mannequin arm. They will eventually feel confident enough to practice on a real person without feeling nervous or stressed. That is the point when you’ll know your students’ skills are fully developed.

The Steps of Practicing IV Therapy with a Mannequin Arm

Now that you understand the benefits of practicing IV therapy with a mannequin arm, you can proceed. The next thing you must learn is the steps involved in practicing IV skills.

Here are the general steps involved in the IV insertion and treatment process using a mannequin arm:

1) Gather the Necessary IV Supplies

The first step is to gather all the necessary medical supplies to administer IV therapy to a patient. These supplies may include some or all of the following:

• A mannequin arm

• IV catheter (adult patients usually need a 20 to 22-gauge)

• IV fluid bag

• IV tubing

• Tourniquet

• Saline solution

• Syringe

• Medical tape

• Sterile gloves

• Sharps container

The mannequin arm may come prefilled with artificial blood, depending on the model you purchase. If it does not come with artificial blood but supports its use, you can buy the artificial blood separately. Then, fill the arm with blood to produce the realistic backflow effect.

2) Wash and Sterilize Your Hands

Good hand hygiene is essential for any student to learn when training to become a doctor, nurse, or other medical professional. That is why a practitioner will always begin by washing and sanitizing their hands to ensure they are completely germ-free. It is essential to practice this even during a simulated exercise like this one, as it helps students develop the habit of practicing good hand hygiene.

3) Apply the Tourniquet

Wrap the strap of the tourniquet about 2 to 3 inches above the area on the arm where the IV line will be inserted. The tourniquet will palpate the vein to make it more visible while temporarily restricting blood flow through it. Use gloved fingertips to gently touch the vein to test whether it is soft and bouncy rather than hard. If it is smooth, the tourniquet was applied correctly.

The mannequin arm should mimic the feel and palpation of real veins. If your mannequin does not offer this feature, just have your students go through this process as practice without feeling the vein.

4) Clean the Insertion Site

Clean the insertion site by using an antiseptic wipe or a swab containing chlorhexidine or alcohol. Gently move the swab or wipe in a circular motion on the insertion site to clean and disinfect it thoroughly.

5) Stabilize the Vein

Stabilize the vein in the mannequin arm with your other hand by pulling the skin under the insertion site.

6) Insert the Catheter

Use your main dominant hand to hold the IV catheter with the bevel facing upward. Insert the catheter into the vein on the insertion site at a 10 to 30° angle. Watch for the blood flowing back into the flashback chamber of the catheter.

7) Fully Advance the Catheter

Advance the catheter about 1 to 2 millimeters to ensure the catheter tip has entered the vein. Slightly lower the angle and continue advancing the catheter until it is completely inside the vein. Ensure the needle remains steady throughout.

8) Remove the Needle

Hold the catheter in place while carefully and steadily removing the needle. Apply gentle pressure near the catheter tip to minimize the risk of blood spillage.

9) Connect the Extension Tube and Secure the Site

Attach the extension tube (prefilled with saline flush) to the catheter. Remove the tourniquet and secure the catheter in place with medical tape. Make sure everything on the insertion is clean.

10) Flush the Catheter

Slowly flush the catheter with the saline flush. Check the area around the insertion site for any signs of leakage or swelling. If there is no leakage or swelling, everything was done correctly.
