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?
- Penta and PCV: Vastus lateralis in the thigh muscle
What muscle is targeted in the injection?
-Penta and PCV: Vastus lateralis
Write down its origin, insertion and action.
Origin: Great trochanter
Insertion: Tibial tuberosity
Action: It extends the knee
How do you locate this area?
Step 1: Find the child’s outer thigh which is below the hip joint in the
femur.
Step 2: After that, in the upper part of the hip joint, you can find the greater trochanter and near the knee will be the lateral femoral condyle.
Step 3: The injection site will be on the outer middle third of the thigh, formed by splitting the greater trochanter and lateral femoral condyle into three equal halves.
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?
Deltoid
Write down its origin, insertion and action.
Origin: Acromion Process, Scapula and Clavicle
Insertion: Humerus of the deltoid tuberosity
Action: Flexion, extension, and abduction
How do you locate this area?
Step 1: Find the acromion in the bone of the child’s shoulder
Step 2: Next, find the deltoid in the acromion. Deltoid is the triangular muscle that is near the upper arm.
Step 3:The injection site will be on the outer middle third of the deltoid muscle by splitting it into three equal parts.
