7. • Initial Examination
• Classification of Injury
• Special Regional Considerations
• Animal and Human Bites
• Tetanus
• Suture Materials
• Wound Healing/Repair
• Wound Closure
8. Establish airway and control hemorrhage
Rule out C-Spine Injury
Rule out facial bone fractures
Reduce fractures before soft tissue repair
Keep wounds moist during examination:
• Direct inspection of persistent bleeding
• Copious irrigation with saline
• Direct pressure to control bleeding
9. Wounds divided into two groups:
clean and contaminated
Contamination increases with time
“The solution to pollution is dilution”
• Anesthetize wound before irrigation
• Remove foreign bodies
• Tetanus prophylaxis as needed
11. Forehead and Brow
Hair Do not shave eyebrow
Muscles prevent depression
Rule out fractures
Eyelid
Protects globe and drying of cornea
Ophthalmology consult mandatory
Rule out muscle impairment
12. Nose
Soft tissue injuries usually simple
Align nasal structures accurately + casting
Rule out hematoma
Reduce fractures first
Use 6-0 non-absorbable sutures (Nylon or Polypropylene)
Soft tissue repair in then out
13. Ear
Direct blow causes hematoma “Cauliflower ear”
Use 6-0 non-absorbable sutures (Nylon or Polypropylene)
Complex lacerations ???
15. Lip
Vermilion border
Single suture to reorient
Close in layers
Muscle use chromic or Vicryl
Mucosa use chromic or Vicryl
Skin use 6-0 Polypropylene or silk sutures
16.
17. • Peak incidence ages 5-9
• 15-20% of dog bites become infected
• 20-50% of cat bites become infected
• Puncture wound highest rate of
infection
• ????????
• Contaminated with oral flora
as well as with Staph, from
the skin of the victim
18. • Irrigation and debridement are
mainstays of treatment
• Loose primary closure of bite wounds
• Antibiotics G+ve, G-ve, anaerobic
• Antitetanic serum
• S. aureus and Pasteurella canis,
multocida and septica are pathogens
• 2nd look and repair after 2 days
19. Clinical Feature Tetanus Prone Clean, minor wound

Signs of Infection Present Absent
Devitalized tissue Present Absent
Contaminants (dirt, feces,
soil, saliva)

20. 1. Hemostasis : direct simple pressure
: compressive dressing
: tourniquet
: no blind clamp
: no rubber band
2.Pain control : local anesthesia
: regional anesthesia
: general anesthesia
3.Wound cleansing : scrub
: irrigation
: antiseptic
4.Wound exploration
: control bleeding
: identify injured structures
: debridement
: irrigation
: repair injured structures
25. •Wound strength gradually increases during the
healing process:
•2 weeks less than 10%.
•3 weeks up to 20%.
•4 weeks up to 50%.
•3-6 months 70-80% of its original strength
(its maximum strength).
26. •The choice of a particular suture material
should be based on
•the patient,
•the wound,
•the tissue characteristics,
•the anatomic location.
27. “There exists the strange belief that a
plastic surgeon can make an incision
and leave no visible scar and that he
can in fact do away with previously
existing scars”
29. • Basic Principles
Less scarring by primary intention; open wound granulates
and scars
debride and close primarily
Clean wounds can be closed primarily 48 hours after injury
If delayed primary closure, give systemic antibiotics and
place sterile dressing
Stabilize first, then treat soft tissue wounds
We may access fracture through wound
Closure with minimal tension
Handle tissue gently
Use appropriate suture
30. Monofilament or multifilament strands
Absorbable or non-absorbable
Size: Refers to the diameter of the suture
The more “0’s” in the number, the smaller the suture
31. •The optimal suture is:
•easy to handle
•high tensile strength and knot security.
•good elasticity and plasticity
accommodate wound swelling.
•resist infection
•tissue reaction minimal,
•low cost.
NB: no one material is ideal
32. Plain Gut
submucosa of sheep
intestines
Not a true monofilament
Less than 10 day life span in
tissue
100 times the bacterial
adhesion than that of
Polypropylene
33. • Chromic Gut
Plain gut tanned with
chromium salts
Improved strength and
duration
Duration is 2-3 weeks
Knot security greater than
plain gut
Absorption by proteolytic
enzymes
34. • Vicryl
Copolymer of glycolic and lactic
acid
Absorbed by hydrolysis of ester
bond
• PDS
• The best but expensive
37. Polypropylene (Prolene)
Similar to synthetic
monofilament polymers
Knot security and ease of tying
?????
Non Absorbable
good for contaminated
wounds
45. • Simple interrupted
Advantages:
- common, apply rapidly
- can get good eversion of wound edges
Disadvantages:
- eversion of edges takes practice to master
- does not relieve tension from wound edges
- time consuming
50. • Vertical Mattress
Advantages:
- unsurpassed to provide
eversion of wound edges
- relieves tension from
the skin edges
Disadvantages:
- takes time to apply
- produces more cross-marks
- caution must be taken not to
place sutures too tight
52. • Horizontal mattress
Advantages:
- reinforces the subcutaneous
tissue
- relieves tension from the skin
edges better
- can be applied quickly
Disadvantages:
- apposition of wound edges
better with the vertical mattress
68. After wound closure:
Dressings is applied
Antibacterial ointment
may be applied
Remove skin sutures
after ?
Scar will mature in 8-12
months
69. the face, 5-7 days.
the neck, 7 days.
the scalp, 10 days.
the trunk 10-14 days.
The upper extremities, 10-14 days.
the lower extremities, 14-21 days.
83. Goals
: moisture but no maceration
: no infection
: no foreign body
: optimal temperature and pH
Dry Dressing
1. Non – adherent layer
2. Absorptive and protective layer
3. Immobilization
Wet Dressing
0..9% NSS solution is the best one
Antiseptic cream
Hydrocolloid
Calcium alginate
84. So, the ideal wound dressing:
1. Creates ideal microclimate for most rapid and effective
healing (prevents dehydration and is permeable to oxygen)
2. Is sterilisable
3. Provides good absorption of blood and exudates
4. Protects against secondary infection
5. Has sufficient mechanical protection to wound
6. Is non-adherent
7. Is non-toxic
8. Is non-allergenic or sensitizing
9. Does not shed loose material into wound
85. 10. Conforms to anatomical contours
11. Resists tearing
12. Resists soiling
13. Is non-flammable
14. Its properties remain constant in a range of
temperatures and humidities
15. Has a long shelf life
16. Has small bulk (hospital storage problem)
17. Accepts and releases medicaments
18. Is cost effective
97. 3- Cleansing and wash
Wound cleansing is a clean - not sterile - procedure
Before commencing, assess the wound
Not all wounds require cleaning
Wound exudate contains anti-microbial substances,
which are natural wound cleansers.
Reasons to clean a wound Presence of:
Foreign bodies
Debris e.g. slough, residue from hydrocolloid dressings
Purulent exudates i.e. infection
104. 10- Discuss with the patient the wound
progression and add any instruction to
accelerate healing like certain position or avoid
certain movements…etc.
