1 SOFT TISSUE INJURY It is a type of physical trauma where the skin is torn, cut or punctured (an open wound), or where blunt force trauma causes a contusion (a closed wound). In pathology , it specifically refers to a sharp injury which damages the dermis of the skin.
2 Types of Wounds 1. Abrasions - also called scrapes , they occur when the skin is rubbed away by friction against another rough surface (e.g. rope burns and skinned knees).
Avulsions - occur when an entire structure or part of it is forcibly pulled away , such as the loss of a permanent tooth or an ear lobe. Explosions, gunshots, and animal bites may cause avulsions. 3
Contusions - also called bruises , these are the result of a forceful trauma that injures an internal structure without breaking the skin. Blows to the chest, abdomen, or head with a blunt instrument (e.g. a football or a fist) can cause contusions. 4
4. Crush wounds - occur when a heavy object falls onto a person, splitting the skin and shattering or tearing underlying structures. 5
6 5. Cuts - Slicing wounds made with a sharp instrument, leaving even edges. They may be as minimal as a paper cut or as significant as a surgical incision.
Lacerations - also called tears , these are separating wounds that produce ragged edges. They are produced by a tremendous force against the body, either from an internal source as in childbirth, or from an external source like a punch. 7
8 7. Missile wounds - also called velocity wounds, they are caused by an object entering the body at a high speed, typically a bullet . 8. Puncture wounds - these are deep, narrow wounds produced by sharp objects such as nails, knives, and broken glass.

10 First Aid FOR MINOR CUTS 1. Wash your hands with soap to avoid infection. 2. Wash the cut thoroughly with mild soap and water. 3. Use direct pressure to stop the bleeding. 4. Apply an antibacterial ointment. 5. If the cut is likely to get dirty or be re-opened by friction, cover it (once the bleeding has stopped) with a bandage that will not stick to the injury.
FOR MINOR PUNCTURES 1. Wash your hands. 2. Use a stream of water for at least five minutes to rinse the puncture wound. Wash with soap. 3. Look (but DO NOT probe) for objects inside the wound. If found, DO NOT remove -- go to the emergency room. If you cannot see anything inside the wound, but a piece of the object that caused the injury is missing, also seek medical attention
12 To avoid infection and aid healing: • Apply pressure with a clean cloth to stop bleeding •Clean the wound with water •Use an antibiotic ointment to prevent infection •Bandage the wound if it's in an area that might get dirty •Watch for swelling and redness •Get a tetanus booster if you are due for one
13 DON’TS • DO NOT assume that a minor wound is clean because you can't see dirt or debris inside. Wash it. • DO NOT breathe on an open wound. • DO NOT try to clean a major wound, especially after the bleeding is under control.
14 DO NOT remove a long or deeply embedded object. Seek medical attention. • DO NOT probe or pick debris from a wound. Seek medical attention. • DO NOT push exposed body parts back in. Cover them with clean material until medical help arrives. DON’TS
15 immediately if: • The wound is large or deep, even if the bleeding is not severe. • You think the wound might benefit from stitches (the cut is more than a quarter inch deep, on the face, or reaches bone). • The person has been bitten by a human or animal. • A cut or puncture is caused by a rusty object.
16 •You step on a nail or other similar object •An object or debris is embedded -- DO NOT remove yourself. •The wound shows signs of infection (warmth and redness in the area, a painful or throbbing sensation, fever, swelling, or pus-like drainage). •You have not had a tetanus shot within the last 10 years Immediately if:
