• blood vessels
• Oedema
Coagulation - promotes migration of macrophages.
57
What are the 4 features of the proliferation phase?
* Macrophages release chemotactic agents which attracts fibroblasts
* Fibroblasts produce collagen
* Fibroblasts differentiate into myofibroblasts
* Myofibroblasts first appear day 3-5, peak in number at 4-5/12 post burn.
* Myofibroblasts are contractile and pull edges of wound together - scar contracture especially around joints.
* Wound closed with scar.
* Dermis of disorganised collagen. Thick red hypertrophic scars.
* Epidermis lacks connection with dermis.
* Prone to abrasion and micro trauma.
58
What are the 3 features of the remodelling phase?
• Collagen forms crosslinks to strengthen the scar.
| Collagen organised, more parallel. Exercise helps to line up collagen
59
What are 12 features of a hypertrophic scar?
• Excessive collagen deposition by fibroblasts into whorl-like haphazard collagen bundles
• Reduced amount of highly cross linked collagen (reduced skin strength)
• Develops within 1-3 months post-injury, progresses for 3-6 months, gradual regression over time
• Increased blood supply in scar (highly vascular/red)
• Build-up of granulation tissue (thick and raised)
• 2-3x rate of normal skin fibroblasts
• No significant difference in collagen degradation
• Minimal regeneration of elastin fibres
• Changes in ground substance (“bony like”)
• Significantly reduced skin stretch
• Constant contraction through myofibroblast activity
Adhesion to underlying structures
60
What are 11 risk factors for scarring? Explain why?
• Race: Dark skinned = more scarring. Asian and African skin types = less scarring.
• Genetic predisposition: Keloid > hypertrophic scar.
• Site of scar: Head, hands, neck and axilla, across joints
• Depth of wound: Deeper the wound takes longer to heal
• Prolonged inflammation and increased granulation
• Skin grafting: Reduced scar vs wounds > 21 days to heal
• Type of grafting: SSG > full thickness grafts
• TBSA, no. of surgical procedures and anatomical location – increase contracture risk
• Age: Children and adolescents > adults.
○ Children already collagen because growing + additional scar collagen. Scar has to stretch with growth, but it doesn't stretch well - high risk of contracture.
• Female gender
Compliance or access to early treatment: Non-compliance = high risk of scar.
61
What are 8 contributing factors to contractures?
• Depth of Wound
• Time to wound healing
• Large % burn wound
○ Muscle catabolism due to hypermetabolic state
○ Multiple areas to address at once
• Duration of joint immobilisation
• Deconditioning and loss of muscle strength to oppose skin contracture
• Muscle weakness e.g. associated neuropathy
• Other soft tissue or bony pathology: e.g. Heterotopic ossification, underlying fractures and need for longer immobilisation
• Decreased access to or compliance with therapy
62
What are 3 first aid steps (most important) after a burn?
• Stop the burning
○ Stop drop roll / Wrap in blanket / water irrigation
○ Remove heat source
• Copious water irrigation
○ 20 mins cold running water, then cling wrap the wound
○ Avoid dirt/dirty water if possible
Avoid hypothermia: Wrap blanket around patient because skin burn = lose temperature
63
What are 9 medical management steps after a burn?
• Assessment of size and depth of burn
• Fluid resuscitation if TBSA >15%
• Management of airway +/- inhalation injury: Burns around face & neck.
• Escharatomy prevents compartment syndrome.
• Prevention and management of infection: Tetanus injection
• Nutritional support
○ Early enteral feeding reduced morbidity (<24 hours) - shorter ICU stay and reduced wound infections.
○ >15% TBSA burn should have supplemental feeding via oral route
○ High protein diet helps healing.
• Wound management: Conservative vs skin grafting
○ Early debridement and grafting blunts SIRS response and reduces risk of infection (< 48 hours)
○ Priority areas – line sites, trachea site
• Pain management
○ Long acting (MS contin), short acting for procedures (morphine), ketamine
○ Gabapentin – burning pain. Use from the start.
○ Others – entonox (happy gas), anti-anxiety medications

• Flaps are classified as either
○ Skin flaps (skin and subcutaneous tissue with or without underlying fascia)
○ Muscle flaps (flap created from muscle with or without attached overlying skin).
• Difference between a flap and a graft
