Position and anatomical landmarks
The anatomical site of infiltration depends on the location of the scar. The scar is palpated to find its most painful spot(s), recognised by the patient as a sharp pain.
The surrounding area is disinfected and covered with sterile drapes. A needle (22-G) is inserted (under ultrasound guidance) into the most painful spot(s). Bupivacaine 0.25% with 20 mg of methylprednisolone is injected (in 1 ml).
- The most serious complication of the injection is infection.
- Small subcutaneous bleedings may result in a temporary increase in pain after the injection.
