Intramuscular (IM) injections in neonates may be required to administer medications or vaccines.
The anterolateral thigh is the preferred site for IM injection in infants under 12 months of age. Medications are injected into the bulkiest part of the vastus lateralis thigh muscle, which is the junction of the upper and middle thirds of this muscle.
Nursing and medical staff must be familiar with the principles of the administration of medications to an infant. These principles include:
Equipment: required for IM injection includes:
Recommended needle size, length and angle for administering vaccines
* If using a narrow 25 gauge needle for an IM vaccination, ensure vaccine is injected slowly over a count of five seconds to avoid injection pain and muscle trauma.
The use of short needles for administering IM vaccines may lead to inadvertent SC injection and increase the risk of significant local adverse events, particularly with aluminium-adjuvanted vaccines (for example, hepatitis B, DTPa, DTPa-combination or dT vaccines).
