- Wound
- Classification of wounds
- Closed
- a.k.a contusion
- A wound produced by blunt objects, resulting
in damage to the subcut tissue without the
break in the continuity of the skin
- Degree of severity of contusion
- 1st degree
- a.k.a bruise
- characterised by rupture of
capillaries of skin and subcut area
- 2nd degree
- characterised by rupture of
larger bv with accumulation of
blood in subcut area
- hematoma
- 3rd degree
- characterised by tissue damage to a
greater extent and gangrene may
occur. Internal organs may be injured
and symptoms of shock are visible
- Open
- Examples
- Incised wound
- punctured wound
- perforating wound
- poisoned wound
- virulent wound
- caused by bacterial/ fungal/ viral
infection
- ulcerative wound
- abrasion
- maggot wound
- lacerated wound
- penetrating wound
- gunshot wound
- envenomed/bite wound
- granulating wound
- Erosive wound
- avulsion
- Clinical classification of an open wound
- Aseptic
- A wound created under aseptic condition
- Contaminated
- A wound infected with microbes but doesn't start multiplying yet
- Infected
- A wound infected with microbes that have start multiplying, and characterised by pus production
- occur after 8-12 hrs after wound is contaminated
- Approach to wound cases
- History
- Where did he got it?
- When the animal got the wound?
- What causes the wound?
- How the animal got the wound?
- General observation
- What type of wound?
- Location of wound?
- Possible cause of wound?
- Degree of damage?
- Physical exam of wound
- Using a forcep - look for the viability of the injured tissue
- look for oedema or extent of inflammation, necrotic tissue, foreign bodies, specific smell (pus)
- look for the wound edges - may indicate debridement, and identify source of wound
- Probing: finger/ probe/catheter/forcep: identify the depth of wound, look for any foreign bodies
- Treatment
- Aseptic wound
- Suture
- if unable to suture:
- Septic wound
- Following 4 D's principles
- Disinfection
- Check for hge, clip and shave area, apply antiseptic (tr. iodine)
- Debridement
- manual removal of foreign bodies, necrotic tissue
- Chemical debridement using combination of copper sulfate and
magnesium sulfate ( 1:1 ratio) in glycerine, applied to wound
and kept for 48 hrs
- irrigation under pressure
- better removal of FB and necrotic debris and also
causes hyperemia which enhance healing process
- Drainage
- Keep an opening in the ventral most part of
the wound after properly bandged wound
applied with antiseptic (iodine)
- Provide seton on the dorsal part for complete drainage
- Dressing
- Done daily - to promote vascular bed for better healing
- Antiseptic dressing is only helpful once the wound becomes fresh after complete
- Antiseptic/ antibiotic ointments can be used for dressing
- supportive treatment
- systemic antibiotics 3-5 days
- fly repellent
- skin graft if necessary
- Definition
- Wound: is the break of continuity of skin or the subcut
tissue or both, which may or may not accompanied by a
loss of tissue
- Wound healing: is the inherent property of the damaged tissue back into its original shape
- Wound repair: is the restoration of the damaged tissue into its normal shape which is done manually
- Etiology of wound
- Mechanical stress
- Chemical agents
- External violance
- Thermal agents
- Radiation
- Infective agents
