The 3M incision field contains a film that provides a sterile operative surface to the edge of the wound to help reduce the risk of contamination of the surgical site. This field adheres firmly to the edges of the wound, decreasing bacterial migration. The flexible, air-permeable film offers further adaptation to facilitate application, even around difficult anatomical contours. The 82 cm x 45 cm sterile adhesive incision field (adhesive area 60 cm x 45 cm) has 10 units in each pack.
