English to Portuguese Medical Medical: Pharmaceuticals solução tópica

Instructions:

1. Clean and dry skin at least 2 1/2 inches around the wound, making sure to remove skin oil or exudate. For best results, use a sponge moistened with alcohol or saline followed by a firm wipe with a dry sponge.
2. Place the individual vial packed in blister-pak on a hard surface (label facing down).
3. Gently apply pressure on the vial through the blister-pak to crush inner ampule, thereby releasing Mastisol liquid adhesive. (As a safety precaution do not crush the ampule more than once.)
4. Remove individual vial using aseptic technique, peel back lid and deliver vial.
5. Carefully apply a 1/2 inch strip of MASTISOL around the outsideof the wound by gently squeezing the vial - taking care not to come in contact with the wound tissue. Allow Mastisol to dry for 20-30 seconds.
