Use the ice pack unless it bothers the child or there is a sensitivity to cold. The cold adds about 60% of the pain relief in older children and adults. The wings that come with personal Buzzy kits have a soft side that may feel slightly less cold. Always begin with clean, fresh wings from the freezer. Wings must be frozen solid to work optimally. Slide the wings through the elastic band or onto the hook. For patients under 6 months old, patients with cold sensitivity, Raynaud’s or sickle cell disease, use Buzzy without the wings. The child can hold the ice pack in the hand to provide a competing sensation.
