Why is the dorsogluteal IM site generally avoided for routine injections?

Why is the dorsogluteal IM site generally avoided for routine injections?

• A. It is too painful
• B. Higher risk of sciatic nerve injury and variability in landmarks
• C. It requires imaging guidance
• D. It absorbs too slowly

Answer: (B)

The safety of intramuscular injections hinges on predictable anatomy and staying away from neural structures. In the dorsogluteal area, the landmarks used to locate the site can vary a lot between people, and the sciatic nerve runs through or very close to this region. If the needle is placed in the wrong spot or at the wrong depth, it can injure the nerve or deliver medication into subcutaneous tissue instead of deep muscle, leading to pain, numbness, weakness, or paresthesias. Because safer sites have more consistent anatomy and lower risk of nerve injury, the dorsogluteal site is generally avoided for routine injections.
