LACERATION
25
WHAT KIND OF WOUND?
This type of wounds are caused by contact with a rough surface, the skin has been ground away. The wound is shallow, but the area damaged can be extensive. These wounds have the highest risk of contamination by foreign material and objects. Thus requiring extensive cleaning before dressing.
ABRASION
26
WHAT KIND OF WOUND?
Also commonly referred to as bruising, although the outer layer of skin may appear undamaged, there may have been extensive damage to underlying structures. Blood accumulates under the skin causing localised swelling.
CONTUSION
27

31
What precautions must be implemented when packing a wound?
- moisten the packing material with a noncytotoxic solution such as normal saline
- never use cytotoxic solutions (eg. povidone-iodine) to pack a wound
- if using woven gauze, fluff it before packing it into the wound
- loosely pack wound
- do not let packing material drag or touch surrounding tissue before you put it in the wound
- fill all the wound dead space with packing material
- pack the wound until you reach the wound surface, never pack the wound higher
