Day 2 - Wound healing to tetanus Flashcards
Classifications of wounds (4)
- Mechanical caused trauma (biggest group)
o Open injuries, wounds
o Closed injuries (commotion, rupture, etc.)
o Bone fracture - Chemicals caused injuries
o Acids – cause coagulation necrosis
o bases – cause colliquative necrosis - Thermal origin injuries
- Radioactive injuries
Burn – combustion
1 degree
C. Erythematosa
Dry fur, swollen skin, edema, warm, loss of epithels
Burn – combustion
2 degree
C. Bullosa
Vasodilation, leak of serum, vesicles
The base of this type of burn is the corium
* Origin of the pain
Burn – combustion
3 degree
C. Escharctica
Cell injuries, protein aggregation, thrombosis, necrosis
Burn – combustion
4 degree
Carbonisation
Frostbite – congelation
1 degree
Ischemia, hyperaemic, leak of serum, not sensitive
Frostbite – congelation
2 degree
Stasis, thrombus, vesicles, infection
Frostbite – congelation
3 degree
Cell degeneration, stop of circulation, necrosis, loss of larger body parts
Classification of wounds
- Localisation
- Shape and size
- Types
- Origin
- Age
- Healing stadium
- In what way
INCISED WOUNDS (VULNUS SCISSUM ET CAESUM)
- Produced by sharp objects
- Tissue damage minimal (in most cases)
- Edges of wound linear and smooth
- Pain minimal
- Underlying tissue damaged only in the line of the wounds
- Prognosis good
LACERATED WOUNDS (VULNUS LACERUM S. RUPTUM)
- Produced by irregular objects
- Tissue damage extensive
- Edges of wound smooth
- Lacerated, loss of material
- Pain painful
- Underlying tissue extensive damage
- Prognosis depends on the injury
- Secondary healing
- In summer: be careful with myiasis
CONCENTRATION DEPENDENT
- Aminoglycosides and fluoroquinolines
Time dependent
b-lactams and macrolides
have to be above MIC to have an effect
What AB do we normally use?
Bacteriostatics
* Penicillin
* Cephalosporin
* Trimethoprim/sulphonamide
What do we use for regional limb perfusion?
Amikacin
INTERRUPTED VERTICAL MATTRESS SUTURE
Better tension holding than interupted horizontal
Skin, subcutis, fascia
ALLGOWE STITCH (MODIFIED DONATI)
Skin, subcutis
INTERRUPTED CRUCIATE (CROSS MATTRESS)
Stronger than simple inverted
Skin, subcutis
CONTINUOUS LOCK AND FORD INTERLOCKING
More secure when broken
Skin, horse uterus
CONTINUOUS INTRADERMAL/INTRACUTAN
minimal impact on blood vessels of skin
CONTINUOUS LAMBERT S.
Penetrates the submucosa, but not the lumen.
Closure of hollow viscera
CONTINUOUS CUSHING S (CONNELL SUTURE PATTERN)
Cushing: Inverting. Penetrates the submucosa, but not the lumen of bowel.
Connell: Penetrates submucosa into the lumen.
Both: Closure of hollow viscera.
Hoof bandage
- Dry or wet
- Covering the hoof after surgical procedures, softening hoof capsule
- Extends under fetlock joint
- Usually applied for 3 days
Distal limb bandage
- Covering surgical sites, or covering after intraarticular injections
- Extends from coronary band to the carpus or tarsus
- Fixed to the hoof capsule by impermeable tape
