Intradermal Injection Procedure Introduction

The injection is parenteral therapy. It means giving a therapeutic agent outside the alimentary tract. An intradermal injection is a medical procedure in which a small amount of medication is injected into the dermis layer of the skin, which is located just below the epidermis (the outermost layer of the skin). This type of injection is used for various purposes, such as administering vaccines or allergy tests. During an intradermal injection, a healthcare provider will use a very fine needle to inject the medication into the skin. The injection site is typically on the inner forearm, although other sites such as the upper arm or upper back may also be used because the needle used for an intradermal injection is very small, the injection itself is usually not painful, although there may be a slight stinging or burning sensation. Some people may experience mild swelling, redness, or itching at the injection site, but these side effects are generally mild and short-lived. Intradermal injections are commonly used for certain types of vaccines, such as the tuberculosis vaccine, as well as for allergy tests to determine if a person is allergic to a particular substance. They are generally considered safe and effective when administered by a qualified healthcare provider.

 Intra-dermal injection definition

An intradermal injection is a type of injection that is given into the dermis, the layer of skin just below the outer layer (epidermis). This type of injection is used to administer small amounts of medication, such as vaccines or allergy tests.

Intra-dermal injection Purpose

Intradermal injection is a type of injection that delivers a small amount of medication or vaccine into the dermis, the layer of skin just below the epidermis. The purpose of an intra-dermal injection is to provide a more targeted and precise delivery of medication or vaccine.

Intradermal injections are commonly used for a few specific purposes, including:

Tuberculosis (TB) skin tests: Intradermal injections are the preferred method for performing TB skin tests, which are used to determine if a person has been exposed to TB bacteria.

Allergy testing: Intradermal injections are used to test for allergic reactions to specific substances, such as pollen, pet dander, or medications.

Vaccinations: Some vaccines can be given intradermally, including the Bacillus Calmette-Guérin (BCG) vaccine for TB and the hepatitis B vaccine.

Cosmetic procedures: Intradermal injections can also be used for cosmetic purposes, such as administering dermal fillers to reduce the appearance of wrinkles or to plump up areas of the face.

Intradermal injections are typically administered using a small needle, and the medication or vaccine is injected just below the surface of the skin. Because the injection is delivered directly into the dermis, it can be more effective than other types of injections that are delivered into muscle or tissue. However, it is important to note that intradermal injections may be more difficult to administer and require specific training and expertise.

Intra-dermal injection Indications

Intradermal injections are indicated for various purposes, including:

Tuberculin testing: Intradermal injections are commonly used to test for tuberculosis (TB) by injecting a small amount of purified protein derivative (PPD) into the skin.

Allergy testing: Intradermal injections are used to determine an individual’s sensitivity or allergy to certain substances by injecting small amounts of allergens.

Local anesthesia: Some procedures require local anesthesia, which can be achieved by injecting an anesthetic agent intradermally.

Intra-dermal injection Contraindications

Intradermal injections may not be suitable in the following situations:

• Active infection or inflammation at the injection site.
• Bleeding disorders or use of anticoagulant medications.
• Allergy to the medication being administered.

Intra-dermal injection Advantages and Disadvantages

Intra-dermal injection Advantages

Intradermal injections offer several advantages, including:

• Accurate testing: Intradermal injections allow for precise administration of small amounts of medication or solution, ensuring accurate diagnostic testing.
• Localized effect: The medication remains within the dermis layer, providing a localized effect without affecting the entire body.
• Reduced pain: The dermis layer has fewer pain receptors compared to other areas of the body, making intradermal injections less painful.

Intra-dermal injection Disadvantages

Despite their advantages, intradermal injections have a few limitations, such as:

• Skill requirement: Proper technique and skill are necessary to ensure accurate placement of the medication within the dermis layer.
• Needle visibility: The needle used for intradermal injections is very small and may be difficult to
  visualize, increasing the risk of incorrect needle placement.

Preparation of patient and environment

• Identify the patient correctly
• Explanation of the procedure to the patient
• Provide privacy with curtains and drapes if needed
• As far as possible avoid meal timing
• Clear the patient’s doubts
• Place the patient in a comfortable position
• For intradermal injection- select an area where the skin is healthy, free from any irritation swelling, edema, or discoloration, and where the clothing will not irritate the skin,
• Usually, the intradermal injection is given at the inner aspect of the lower arm, the upper aspect of the anterior chest, and the upper aspect of the posterior chest.

Intradermal Injection Procedure

• Review the prescriber’s medication order for the client’s name, medication name, routes, dose, the indication
• Check the date of expiration
• Perform hand washing
• Explain the steps of the procedure to the clients
• wear gloves
• Selection of appropriate site
• Give a comfortable position to the patient
• Loading the drug in the syringes
• Clean the site with an antiseptic swab
• With non-dominant hands, stretch the skin over the site with forefinger or thumb because needle pierces tight skin more easily
• With the needle almost against client’s skin insert it slowly with bevel up at a 5 – 15 degree angle until resistance is felt
• Then advance needle through epidermis to approximately 3 mm below skin surface. Needle tip can be seen through skin
• Inject medication slowly ( 0.01- 0.1 ml)
• While injecting medication, notice that small bleb approximately 6 mm in diameter appears on skin’s surface
• Do not try the clean or massage the area.
• Withdraw syringe by applying swab
• Assist client to comfortable position
• Discard the syringe and remove gloves.
• Inspect the site and observe the clients response.
• Use skin pencil and draw circle around the parameter of injection site, and read site within 48-72 hr. of injection.

Aftercare of patients and articles-

• Assist the patient dress up and give them a comfortable position.
• Ask the patient to take rest and observe the patient for any reaction
• Ask the patient to move the limb to check for any nerve injury
• Discard the disposable syringe
• Clean all the articles and replace them in their usual places.
• Wash hand thoroughly
• Record the procedure.

Intra-dermal Injection Site

The most common injection sites for intradermal injections are the inner aspect of the forearm and the upper back. The selection of the site may depend on the type of test or medication being administered.

Intra-dermal Injection procedure Nursing Responsibilities

Nurses have several responsibilities when performing intradermal injections, including:

• Ensuring proper identification of the patient and verifying the medication order.
• Educating the patient about the procedure, potential side effects, and expected outcomes.
• Assessing the injection site for any signs of infection, inflammation, or bleeding before and after the injection.
• Using an aseptic technique during the procedure to prevent infection.
• Accurately documenting the procedure, including the site, medication administered, and any patient reactions or adverse effects.
• Providing post-injection care and instructions to the patient, including wound care and potential side effects to watch for.
• Monitoring and evaluating the patient’s response to the medication or test performed.

Conclusion

Intradermal injections are an important nursing procedure used for administering medication and performing diagnostic tests. They offer accurate testing and localized effects but require skill and proper technique.

Key Points to remember

The angle of intradermal injection

• The needle used for an intradermal injection is very fine and short, usually between 3/8 and 5/8 of an inch in length.
• The medication is injected at a shallow angle, typically between 5 and 15 degrees, into the top layer of the dermis. Because the injection is given into the skin, rather than into muscle or a vein, it may produce a small wheal or bump at the injection site, which is a normal reaction.

Conclusion

Intradermal injection medication procedures play a crucial role in healthcare, particularly for diagnostic testing, immunizations, and allergy testing. While relatively simple in technique, intradermal injections require precision and careful attention to detail to ensure accurate administration and minimize the risk of complications. Healthcare professionals must adhere to established protocols and guidelines, including proper site selection, needle insertion angle, and injection volume, to optimize patient safety and therapeutic effectiveness. Patient education and communication are also essential to alleviate anxiety, ensure compliance with treatment regimens, and promote positive health outcomes. By following standardized procedures and prioritizing patient-centered care, healthcare providers can enhance the quality and safety of intradermal injection medication administration.

Frequently Asked Questions (FAQs)

What is the purpose of intradermal injections?

Intradermal injections are commonly used for diagnostic purposes, such as tuberculin skin testing (TST) for tuberculosis screening, as well as for administering certain vaccines and allergen testing. They allow for the delivery of small amounts of medication or substances directly into the dermis layer of the skin.

Where are intradermal injections typically administered?

Intradermal injections are typically administered on the inner forearm or upper back, where the skin is relatively thin and has minimal underlying blood vessels or nerves. The injection site should be clean, dry, and free from any lesions or abrasions.

How is the injection site prepared before administering an intradermal injection?

Before administering an intradermal injection, the injection site should be cleansed with an antiseptic solution and allowed to dry completely. The healthcare provider may use a skin marker to mark the injection site and ensure accurate placement of the needle.

What are the potential complications of intradermal injections?

Potential complications of intradermal injections include pain, bleeding, hematoma formation, infection, and tissue damage. Improper technique or failure to adhere to sterile practices may increase the risk of adverse events.

How should patients care for the injection site after receiving an intradermal injection?

Patients should be instructed to avoid rubbing or scratching the injection site and to observe for any signs of infection, such as redness, swelling, or discharge. It is important to follow any additional post-injection care instructions provided by the healthcare provider.

Can intradermal injections be self-administered at home?

In some cases, intradermal injections may be self-administered at home, particularly for medications such as insulin or allergy immunotherapy. However, proper training and supervision by a healthcare professional are essential to ensure safe and effective self-administration.

Why is BCG Injection administered intradermally?

Intradermal injections are typically used for administering vaccines such as tuberculosis or for allergy testing this is because the skin contains many immune cells that can help generate an immune response to the vaccine or allergen.
