General injection considerations Standard methods regardless of area
âą For each injection, the injection volume will be 0.1 mL (equivalent to 5 Units)1 âą Consider injecting in the most superficial aspect of the muscle âą Evaluate the anatomy, including relevant function and the effects of treatment on these muscles (eg, weakening)
âą Recognise unique anatomy, as no two patients are alike; focus on the muscle, not measurements, to adjust for individual anatomical variations
âą Consider location, depth, and angle carefully, as the site of medication delivery may be different from the needle insertion point
â Injection sites depicted in diagrams represent delivery point of the medication
Before injection
âą Examine the patient to identify unique anatomy and any muscle weakness or pain/tenderness
â Visually inspect the muscle â Ask the patient to activate the muscle â Palpate the muscle
âą Verify the needle is securely fastened to the injection syringe âą Line up the bevel of the needle with the gradations on the syringe so the bevel is facing upward; this will help you more easily orient the bevel of the needle when injecting
