Position and anatomical landmarks
The anatomical side of infiltration is dependent of the localisation of the scar. The scar is palpated to find the most painful spot(s) of the scar and recognised by the patient as a sharp pain.
The area around is disinfected covered with sterile drapes. A needle (22G) is inserted (under ultrasound guidance) in the most painful spot(s). Bupivacaine 0.25% with 20 mg of methylprednisolone is injected (in 1cc).
