When is the Z track method used?
Show When administering iron dextran via IM injection, use the Z-track method! What is the Z-Track Method?The z track method is the process of putting medications into muscle tissue without allowing for them to leak/track back into subcutaneous tissue that lays over the muscle. It is given the “z” name because when conducting this method, the skin and tissue is required to be pulled prior to inserting the syringe causing the needle track to take the shape of a z. Why Use the Z-Track MethodThe z method is not a common method but has proven to be useful when wanting to administer medication that needs to be absorbed by muscle in order to effectively work. And because this method helps prevent the leakage of medication it can help ensure that a full dosage is received. When to Use Z-Track Method?The z track method is only really recommended for specific medications, such as iron dextran, when performing intramuscular injections (I.M.) on adults. This is because it helps ensure that the medication is reaching the right muscle and not leaking into other tissue. What is the Purpose of the Z Track Method?The purpose of the z track method is to allow for a full dosage of medication to reach the desired tissue without leaking into other tissue and causing irritation. Z-track method of intramuscular injection is used to administer drug in a large muscle that prevents the leakage of the medication into the layers of subcutaneous tissues. It is named Z-track because after the techniques of this medication administration are implemented a zigzag path is responsible for sealing the drug in the muscles. Irritating medications and those that cause discoloration such as Iron Dextran and Inferon preparations are administered intramuscularly using this method. Tissue irritation is minimized by the lateral displacement of the skin during injection that seals the drug into the muscle tissue, thereby, inhibiting the escape of drug injected into the subcutaneous layer of the skin. The procedure requires a thorough concentration to the technique because leakage of the injected drug causes permanent staining of some tissues and patient uneasiness. A large and deep muscle must be used in this procedure. Preferably, the ventrogluteal muscle is usually selected as the site of IM injection. Preparation
