1) It is immunization day at the health center. The first patient is a 2-month old well female infant who is scheduled for the following vaccinations: pneumococcal conjugate vaccine (PCV), pentavalent vaccine (Penta) and oral polio vaccine. PCV and Penta are given via intramuscular route. Where are the sites of injection? What muscle is targeted in the injection? Write down its origin, insertion and action. How do you locate this area?
The injection site for a 2 month old baby would be the anterolateral thigh and the targeted muscle would be the vastus lateralis. The origins of these muscles are the greater trochanter and linea aspera of the femur. To injection site can be found in the anterolateral part of the mid-thigh.
2) The baby’s 65-year-old grandfather also came to the center because influenza vaccine is being offered to senior citizens. The flu vaccine is given intramuscularly. Which muscle is the preferred site for IM injection in this case? Write down its origin, insertion and action. How do you locate this area?
The deltoid muscles is the ideal site for administering the flu vaccine for adults. The site of origin are the acromion of the spatula, the spine, and the lateral and posterior clavicular fibers. To find the location, by flexing the arm and being rotated laterally internally, feel the bone at the top of the arm and there you will find the location to administer the injection.
