 Inflammatory Phase
 Proliferative Phase
 Remodeling or Maturation Phase
•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).
•The choice of a particular suture material
should be based on
•the patient,
•the wound,
•the tissue characteristics,
•the anatomic location.
“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”
 Types of wound closure
 Linear Wounds:
 primary closure
 delayed primary closure
 secondary closure
 Wide Area Wounds:
 Partial-thickness wound closure
 Full-thickness wound closure
 Compound wound closure
 Re-implantation
• 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
 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
•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
 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
• 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
• Vicryl
 Copolymer of glycolic and lactic
acid
 Absorbed by hydrolysis of ester
bond
• PDS
• The best but expensive
• Dexon
 Silk
 Polypropylene (Prolene)
 Similar to synthetic
 monofilament polymers
 Knot security and ease of tying
?????
 Non Absorbable
 good for contaminated
wounds
Tapered
Cutting
Reversed Cutting
1/4 circle
1/2 circle
3/8 circle
3/4 circle
Curve-ended
straight Straight
 Needle Holder
 Scalpel
1. SUTURE
2. STAPLES  Stainless steel
3. TAPES  Steri-strips
4. TISSUE ADHESIVES 
Octylcyanoacrylate (Dermabond)
• 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
• Simple interrupted
• Continuous over and over
• Running locked stitch
 Subcutaneous Sutures (inverted)
1
43
2
• 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
 Vertical mattress stitch
• 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
 Horizontal mattress stitch
• Mattress sutures
• Half – buried horizontal matress suture
• Subcuticular suture
• Skin staples
• Skin adhesive strips
Epidermis
Dermis
Muscle
Submucosa
Mucosal Epithelium
1- flat knots
- square knots
- surgeon's knots.
2- instrumental tie.
3- deep tie.
4- ligation around clamp
 Simple Surgeon Knot
 Surgeon Knot
 Instrumental Knot
 Deep structure Knot
 Ligation around a clamp
 Lumen structure Knot
 After wound closure:
 Dressings is applied
 Antibacterial ointment
may be applied
 Remove skin sutures
after ?
 Scar will mature in 8-12
months
 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.
• Scar formation
 Foreign material
 Necrosis
 Ischemia
 Wound tension
 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
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
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
 Types:
 Biological, synthetic.
 Time:
 Temporary, permanent.
 Technique:
 Dry, wet-to-dry, wet-to-wet

BiocCore (Collagen) Integra (tissue eng.)
Biobrane (Synth.derm) Cutured keratinocytes
 Debriding agents:
Saline gush Wound
cleansing
Iruxol (Collagenase) Surgical
Wound Type Type of Dressing
Dry, necrotic wounds Deriding agent > synthetic
Slough-covered wounds Deriding agent > synthetic
Clean, exuding wounds
(granulating)
Synthetic or biosynthetic
Wound Type Type of Dressing
Clean, dry, low exudate wounds
(epithelialising)
Biosynthetic or biological
Clean, medium-to-high exudate
wounds (epithelialising)
Synthetic, biosynthetic or
biological
Cavity e.g bed sore Deriding agent + Vaccum
1- Preparation
2- Remove old dressing
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
4- Sterilization
5- Dry the wound
6- Application of dressing agent
7- Application of dry gauze
8- Application of dry dressing
9- Bandage
10- Discuss with the patient the wound
progression and add any instruction to
accelerate healing like certain position or avoid
certain movements…etc.

  • 23.
  • 24.  Inflammatory Phase  Proliferative Phase  Remodeling or Maturation Phase
  • 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”
  • 28.  Types of wound closure  Linear Wounds:  primary closure  delayed primary closure  secondary closure  Wide Area Wounds:  Partial-thickness wound closure  Full-thickness wound closure  Compound wound closure  Re-implantation
  • 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
  • 38. Tapered Cutting Reversed Cutting 1/4 circle 1/2 circle 3/8 circle 3/4 circle Curve-ended straight Straight
  • 39.
  • 40.
  • 43.
  • 44. 1. SUTURE 2. STAPLES  Stainless steel 3. TAPES  Steri-strips 4. TISSUE ADHESIVES  Octylcyanoacrylate (Dermabond)
  • 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
  • 49.  Subcutaneous Sutures (inverted) 1 43 2
  • 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
  • 55. • Half – buried horizontal matress suture
  • 60. 1- flat knots - square knots - surgeon's knots. 2- instrumental tie. 3- deep tie. 4- ligation around clamp
  • 67.
  • 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
  • 86.  Types:  Biological, synthetic.  Time:  Temporary, permanent.  Technique:  Dry, wet-to-dry, wet-to-wet  Method:  Open, semi-open,  semi-occlusive, occlusive.  Chronological  Conventional  Membranous. Types of Wound dressing
  • 87.  Biological: - Xenografts - Allografts - Alloderm (Acellular human dermis)
  • 88.  Synthetic: Telfa (Absorbant) Xeroform (Low adherent) Opsite (semiperm.film) Tegagerm (semiperm.film)
  • 89.  Synthetic: Inadine (non-adherent) Intrasite Gel (hydrogel) Tielle (Hydroplymers) Duoderm (hydrcolloids)
  • 90.  Synthetic: AquacelAg (Hydrofiber) Kaltostat (Alginates) LyoFoam (Synth.foam) Actisorb (Charcoal)
  • 91.  Biosynthetic: BiocCore (Collagen) Integra (tissue eng.) Biobrane (Synth.derm) Cutured keratinocytes
  • 92.  Debriding agents: Saline gush Wound cleansing Iruxol (Collagenase) Surgical
  • 93. Wound Type Type of Dressing Dry, necrotic wounds Deriding agent > synthetic Slough-covered wounds Deriding agent > synthetic Clean, exuding wounds (granulating) Synthetic or biosynthetic
  • 94. Wound Type Type of Dressing Clean, dry, low exudate wounds (epithelialising) Biosynthetic or biological Clean, medium-to-high exudate wounds (epithelialising) Synthetic, biosynthetic or biological Cavity e.g bed sore Deriding agent + Vaccum
  • 96. 2- Remove old dressing
  • 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
  • 99. 5- Dry the wound
  • 100. 6- Application of dressing agent
  • 101. 7- Application of dry gauze
  • 102. 8- Application of dry dressing
  • 104. 10- Discuss with the patient the wound progression and add any instruction to accelerate healing like certain position or avoid certain movements…etc.
