This is the suture of a wound within six hours of the injury, but it is only safe if the wound is clean, and if it contains no dead tissue. All other wounds are best packed with gauze and left open to see what happens 3 days later (54.4).
When you suture any wound, aim to: (1) Close it at all points and in all planes. Suture it so as to obliterate dead spaces in which blood and exudate can collect as in B, and C, Fig. 54-5. If you allow them to collect, as in F, and G, in this figure, they may become infected, and when they finally organize they will cause a denser scar. (2) Cause as little trauma as you can by using sharp needles and fine sutures. Avoid heavy toothed forceps, blunt knives, and tissue forceps on the skin edges.
