A wound can be claused by any injurious agent & can involve any tissue or structure.

Rank & Wakefield classification: Wounds –         1. Tidy &

2. Untidy

Tidy: by sharp instruments & containing no devitalized tissue as in surgical intervention.

Untidy: Results from crushing, tearing, avulsion, vascular injuries or burns & contains devitalized tissue.

Types of wound:

1.    Bruise

2.    Contusion

3.    Hematoma

A close blunt injury.

4.   Punctured wound

5.   Bites

Open wounds usually contains foreign materials & organism are carried down.

6.   Abrasion

7.   Friction burn

8.   Laceration: like that of surgical incised wound involving skin, muscles, vessels, tendons.

9.   Traction

10.   Avulsion

Open injury associated with severe degree of tissue damage

11.Crush injury: variant of blunt injury with digloving/ compartment syndrome.

Injuries to the arteries & veins

Wound with much bleeding there is possibility that a vessel has been divided.

1^st aid: bleeding can be controlled by pressure & elevation. The torn vessel must be repaired under anesthesia.

War wound & gun shot

Injuries are of different severity of tissue damage depending on Low or High velocity missiles.

Low velocity: from hand gun, results into Entry – small wound & Exit – large wound associated with severe tissue contamination with clothing, dirt or F.B.

High velocity: (from modern rifles) cause explosive pressure & results into wide spread tissue damage.

Chronic wound

Several velocities are as follows:

Ulcer: is any breach in  results from failure to heal in due time.

Treatment – Consists of specific management of the underlying cause.

Pressure sore / Bed sore / Decubitus ulcer: occurs over bony prominence due to –

                                                                                                      i.            Ischemia

                                                                                                   ii.            Moist

                                                                                                iii.            Pressure

                                                                                                iv.            Anesthetic area

Treatment –  a. To avoid pressure    b. Treatment of the wound.
