Medication Administration: Intramuscular Injection (Pediatric) - CE

ALERT

Use the intramuscular (IM) injection route in pediatric patients only when the benefits outweigh the pain of injection.

Take steps to eliminate interruptions and distractions during medication preparation.

OVERVIEW

The purpose of IM injections is to administer medication safely into the muscle below the subcutaneous layer. Many medications must be injected intramuscularly because of chemical properties, pharmacokinetics, desired onset, intensity and duration of the effect, and certain patient characteristics related to treatment compliance. An IM injection should be given only when less painful options are not feasible.

The injection site affects how much fluid can be given and how quickly the medication will be absorbed. The most appropriate sites for IM injections are the vastus lateralis (anterolateral thigh) for infants and toddlers and the deltoid muscle for pediatric patients 18 months old or older.undefined#ref1">1 Selection of the injection site is based on the patient’s age, muscle mass, medication volume, and medication viscosity.

Local anesthesia or tactile stimulation should be considered to decrease pain at the injection site.1 Breastfeeding or giving supplemental breast milk during the injection can reduce pain in infants. The combination of oral sucrose and radiant warmth is effective analgesia for healthy neonates and young infants receiving IM vaccination.1 Diversional activities and education may comfort a patient receiving an IM injection. A child life specialist should be enlisted to support the patient, if available.

Because the recommended sites for pediatric IM injections for vaccines have no large blood vessels, the practice for immunization is unnecessary.2 However, aspiration is routinely used and is recommended when medications other than vaccines are administered.

If the patient or family expresses concern regarding the accuracy of a medication, the medication should not be given. The concern should be explored, the practitioner notified, and the order verified.

EDUCATION

  • Provide developmentally and culturally appropriate education based on the desire for knowledge, readiness to learn, and overall neurologic and psychosocial state.
  • Provide the family and patient with appropriate verbal and written information about the medication, including its purpose and the reason for the IM route.
  • Instruct the family regarding the potential adverse effects of the medication.
  • Explain to the patient and family the step-by-step procedure for IM medication administration.
  • Explain that the patient may feel pain and anxiety during the procedure. Collaborate with the patient and family to develop a plan for pain management.
  • Explain which strategies (e.g., breastfeeding, local anesthetic use, distraction), may be used to minimize the patient’s pain and anxiety during the procedure.
  • Explain how the family can participate during the procedure.
  • Explain how the patient can assist by holding still.
  • Provide the family and patient with self-management techniques (e.g., acetaminophen for fever and cool compresses for pain). Tell them when and how to notify the practitioner about a problem.
  • Encourage questions and answer them as they arise.

ASSESSMENT AND PREPARATION

Assessment

  1. Perform hand hygiene before patient contact.
  2. Introduce yourself to the patient and family.
  3. Verify the correct patient using two identifiers.
  4. Review the patient’s history for reactions or allergies to medications, foods, or environmental allergens.
  5. Assess the patient for specific contraindications to receiving the medication and advise the practitioner accordingly.
  6. Assess the patient’s developmental level and ability to interact.
  7. Assess the patient’s and family’s experiences with IM medication administration.
  8. Assess the patient’s and family’s understanding of the reasons for and the risks and benefits of the procedure.
  9. Assess the patient’s muscle mass and skin condition.
  10. Assess the family for ways they can assist in the procedure.
  11. Determine the patient’s desire for the family to be present during the procedure.
  12. Determine the family’s desire to be present during the procedure.

Preparation

  1. Verify the patient’s daily weight in kilograms. Stated, estimated, or historical weight should not be used.3
  2. Obtain consent, when appropriate.
    Ensure that parental or legal guardian consent is obtained for immunizations per the organization’s practice.
  3. Select an appropriate injection site based on the patient’s age and muscle mass, the medication volume, and the viscosity of the medication (Figure 1)Figure 1 (Figure 2)Figure 2 (Table 1)Table 1.
    Tissue or nerve damage, scar tissue, poor muscle mass or tone, and lack of accessibility may be contraindications to using a particular site.
  4. Apply a topical anesthetic as ordered. Follow the manufacturer’s instructions for application and time to peak effect.
  5. Consider consulting a child life specialist if available.
  6. Obtain the medication and verify the expiration date.
  7. Inspect the medication for particulates, discoloration, or other loss of integrity.
    Do not use any medication that is cloudy or precipitated unless such is indicated by its manufacturer as being safe; otherwise, this may lead to harmful reactions.
  8. Review medication information pertinent to the medication’s action, purpose, onset of action and peak action, normal dose, common side effects, and nursing implications, if needed.

PROCEDURE

  1. Perform hand hygiene.
  2. Verify the correct patient using two identifiers.
  3. Explain the procedure to the patient and family and ensure that they agree to treatment.
  4. Check the accuracy and completeness of the medication administration record (MAR) with the practitioner’s original order.
  5. Ensure the six rights of medication safety: right medication, right dose, right time, right route, right patient, and right documentation. Use a bar code system or compare the MAR to the patient’s identification band.
  6. Mix and draw up the exact volume of medication. Use a filter needle if drawing the medication from a glass ampule.
    Rationale: A filter needle prevents glass and large particles from being drawn into the syringe.
  7. Attach an appropriate-size needle to the syringe (Table 1)Table 1.
  8. Label all medications and medication containers. The only exceptions are medications still in their original container or medications administered immediately by the person who prepared them.4
  9. Provide privacy, as needed.
  10. Position the patient and initiate developmentally appropriate distraction measures. Have the family of an infant begin breastfeeding or feeding breast milk. For an infant who is unable to breastfeed or for an infant who does not breastfeed, consider nonnutritive sucking, sucrose, and warmth.1
    Position the patient to relax the muscle. Placing the patient’s hand on the hip relaxes the deltoid muscle. For the vastus lateralis site, the patient can sit on an adult’s lap. Some distraction techniques involve books, cell phones, tablets, music, videos, pictures, bubbles, and toys.
  11. Don gloves.
  12. Cleanse the area with an antiseptic solution and allow the skin to dry.
  13. Administer the injection.
    1. Nonvaccine administration
      1. Stretch the skin or pull it laterally at the injection site to achieve flattening (Z-track) or use the bunching technique.
        Rationale: Stretching the skin increases the likelihood of administering the medication into the muscle. Pulling the skin to the side (Z-track) method should be used with medications that are irritating to the tissue. 1 Bunching is useful when there is little muscle tissue. Applying manual pressure before the injection may decrease pain.
      2. Insert the needle at a 90-degree angle to the skin, using a steady, smooth motion.1
      3. After the needle pierces the skin, use the thumb and forefinger of the nondominant hand to hold the syringe barrel while still pulling on the skin. Move the dominant hand to the end of the plunger. Avoid moving the syringe.
      4. Pull back on the plunger. If no blood appears inject the medication over several seconds.
        Rationale: Injecting the medication over several seconds allows the muscle to stretch and accommodate the volume with less leakage into the subcutaneous tissue.
    2. Vaccine administration
      1. Stretch the skin or pull it laterally (Z-track) at the injection site to achieve flattening or use the bunching technique.
        Rationale: Stretching the skin increases the likelihood of administering the medication into the muscle. The Z-track method should be used with medications that are irritating to the tissue. 1 Applying manual pressure before the injection may decrease pain.
      2. Insert the needle at a 90-degree angle to the skin, using a steady, smooth motion.1
      3. Inject the vaccine into the tissue.
        Because the recommended sites do not contain large vessels, aspiration is not necessary when vaccines are administered. 2
        Vaccines take less time to inject than medications, such as penicillin, because vaccines are thinner and have less volume.
  14. Remove the needle and syringe quickly and smoothly. Activate the needle safety device per the manufacturer’s instructions.
  15. Apply pressure at the injection site.
    Do not massage the site. Use gauze, not an alcohol wipe, to prevent skin irritation.
  16. Assess the injection site for complications and apply an adhesive bandage.
    If the patient is an infant or toddler, a bandage can become a choking hazard. If one is applied, explain to the family that it must be removed before the patient is left alone.
  17. Praise the patient for positive behavior and allow the patient to express any feelings after the procedure.
  18. Discard supplies, remove gloves, and perform hand hygiene.
    At the completion of the procedure, ensure that all choking hazards (e.g., syringe caps, medication caps, alcohol wrappers, bandages) are removed from the patient’s linens and placed in the appropriate receptacle.
  19. Document the procedure in the patient’s record.

MONITORING AND CARE

  1. Monitor the patient’s tolerance of the procedure.
  2. Assess for the intended response to medication.
  3. Monitor the patient for adverse and allergic reactions to the medication. Recognize and immediately treat dyspnea, wheezing, and circulatory collapse, which are signs of a severe anaphylactic reaction. Follow the organization’s practice for emergency response.
    Reportable conditions: Adverse medication, medication-to-medication interaction, or allergic or anaphylactic reaction
  4. Monitor the injection site for tissue injury.
    Reportable conditions: Profuse bleeding, hematoma, loss of function, signs and symptoms of infection
  5. Assess, treat, and reassess pain.
