Occasionally patients present with parallel wounds in close proximity. The following techniques demonstrate rapid closure of multiple parallel wounds. Methods 1 and 2 are for two parallel wounds. Method 3 can be used for numerous parallel wounds.
Indications
Linear, parallel wounds of approximately the same size.
Method 1: Simple Interrupted

Throw the needle through the epidermis on the far side of the farther wound, entering the “tissue island” between the parallel wounds at the dermis
Exit through the dermis on the near side of the island and reload the needle.
Pass the needle through the near wound’s closest edge, exiting through the epidermis.

Method 2: Horizontal Mattress

Throw the needle through the epidermis on the far side of the farther wound, entering the “tissue island” between the parallel wounds at the dermis
Exit through the dermis on the near side of the island and reload the needle.
Pass the needle through the near wound’s closest edge, exiting through the epidermis.
Using a backhand technique, drive the needle through the near wound’s closest edge and passing through the dermis of the tissue island
Reload the needle and drive it through the far side of the farther wound, approximately the same distance from the wound edge and along the plane of the wound creating a square of entry/exit points

Method 3: Figure of Eight

Throw the needle through the epidermis on the far side of the farthest wound, exiting the far “tissue island” through the epidermis
Reload the needle and drive it through the epidermis of the next tissue island, continuing in the same fashion until you exit the near wound’s closest edge
Using a backhand technique, pass the needle from the near wound’s closest edge and exit through the tissue island
Continue passing the needle in a backhand fashion through each tissue island until you exit the far side of the farthest wound

Common Pitfalls
Beware of compression of the “tissue islands” in the middle of the parallel lacerations. The mattress suture method in method 2 can cause puckering in the wound.
