Selecting the proper needle length when vaccinating your patients is critical – vaccine must reach the desired tissue site for optimal immune response to occur. To determine the proper needle length to use in each situation, you must consider the following factors:
Below is a summary of the guidance for choosing the proper needle length for intramuscular and subcutaneous injections based on CDC�s General Best Practice Guidelines for Immunization (Vaccine Administration). Show FOR INFANTS, CHILDREN, AND TEENS Intramuscular (IM) injections: Injection site and needle size
Subcutaneous (Subcut) injections: Injection site and needle size
FOR ADULTS Intramuscular (IM) injections The deltoid muscle is most often used as the site for IM injections in adults. Needle length is usually 1"–1�", 22–25 gauge, but a longer or shorter needle may be needed depending on the patient's weight. Note: An alternate site for IM injection in adults is the anterolateral thigh muscle. The needle length and gauge are the same as when the deltoid muscle is used, i.e., 1"�1�" length, 22�25 gauge. You should choose needle length based on the weight of your adult patients, as follows:

Which is the maximum volume of an intramuscular injection recommended for preschool age child?Medication fluid amounts up to 0.5-1 mL can be injected in one site in infants and children, whereas adults can tolerate 2-5 mL. Intramuscular injections are administered at a 90-degree angle.
What is the maximum volume for intramuscular injection in a child?The anterolateral aspect of the thigh, or vastus lateralis muscle, is the preferred IM site for neonates and infants. Up to 1ml can be injected into this site in neonates, up to 3mls in children and up to 5mls in adults.
What is the maximum subcutaneous injection amount for a 6 year old child quizlet?What is the maximum subcutaneous injection amount for a 6-year-old child? 1 mL (For patients more than 12 months old, the maximum subcutaneous injection amount is 1 mL.)
Why are intramuscular injections avoided in children?The most common serious complications of intramuscular injections in children are muscle contractures and nerve injury. Muscle contracture occurs most commonly after injections in the anterior and lateral thigh, and sciatic nerve injury is the most frequently reported serious complication of the gluteal area.
