Intramuscular
• Given into the muscle layer beneath
the dermis and subcu tissue
• Intermediate absorption rate
• 3 mL syringe
• 19 – 25g needle
• 1 to 3 inch needle length
Land marking for IM

Deltoid
Ventrogluteal
Vastus lateralis or rectus femoris
Dorsogluteal
Deltoid
• Small muscle with little subcu fat
• Absorbed quickly
• Smaller volume of medication (no more
than 1 mL)
• Anatomical risk: radial nerve and brachial
artery
Vastus Lateralis
•
•
•
•
Absorption rapid
Site of choice for infants and children
1 inch needle for children
Lift muscle from bone and administer at
right angle to the muscle
Ventrogluteal
• Lateral hip; free of major blood vessels,
nerves and fat
• 90 degree angle
• Least painful
Dorsal Gluteal
• Site is close to sciatic nerve and superior
gluteal artery so accurate landmarking is
critical
• Not used on infants and toddlers
Z-Track Method
• IM injection where solution will irritate
subcu tissue
• Allows medication into muscle with no
tracking to subcu tissue
• 0.2 mL of air used as airlock to prevent
leak into subcu tissue
