Anatomy

Types
• Thermal• Cold exposure• Chemical• Electrical current• Inhalation• Radiation
![Page 5: Evaluation and Management of Burns](https://reader036.vdocuments.us/reader036/viewer/2022062315/5681600d550346895dcf0cc7/html5/thumbnails/5.jpg)
Severity
• Size• Depth• Site
![Page 6: Evaluation and Management of Burns](https://reader036.vdocuments.us/reader036/viewer/2022062315/5681600d550346895dcf0cc7/html5/thumbnails/6.jpg)
Size
• Percentage of body surface area estimates– Palm method = 1%– Rules of Nines• Each leg represents 9 x 2 = 18%• Each arm 9%• Anterior and posterior trunk each 9 x 2 = 18%• Head 9%

Depth
• Colour• Moist vs dry• Blanching• Blisters• Pain
![Page 9: Evaluation and Management of Burns](https://reader036.vdocuments.us/reader036/viewer/2022062315/5681600d550346895dcf0cc7/html5/thumbnails/9.jpg)
Superficial
• Only epidermal layer• Painful• Dry• Red• Blanch with pressure• Do not blister• Heal 5-7 days• No scarring
![Page 10: Evaluation and Management of Burns](https://reader036.vdocuments.us/reader036/viewer/2022062315/5681600d550346895dcf0cc7/html5/thumbnails/10.jpg)
Superficial Partial Thickness
• Epidermis and superficial part of dermis
• Painful• Red• Weeping• Blanches with pressure• Heal in 7-21 days• Unlikely scarring, pigment
changes may occur
![Page 11: Evaluation and Management of Burns](https://reader036.vdocuments.us/reader036/viewer/2022062315/5681600d550346895dcf0cc7/html5/thumbnails/11.jpg)
Deep Partial Thickness• Epidermis and deeper
dermis• Painful to pressure only• Blister• Wet or waxy dry• Mottled colorisation• Do not blanch with
pressure• Heal in 3-9 weeks• Hypertrophic scarring
likely
![Page 12: Evaluation and Management of Burns](https://reader036.vdocuments.us/reader036/viewer/2022062315/5681600d550346895dcf0cc7/html5/thumbnails/12.jpg)
Full Thickness• Extend through all layers
of dermis• Anaesthetic or reduced
sensation• Appearance varies• Dry• Do not blanch with
pressure• No vesicles• Severe scarring with
contractures• Usually require grafting

Forth Degree
• Deep and extend through skin into underlying tissues such as fascia, muscle and/or bone
![Page 14: Evaluation and Management of Burns](https://reader036.vdocuments.us/reader036/viewer/2022062315/5681600d550346895dcf0cc7/html5/thumbnails/14.jpg)
Dangerous Sites
• Face• Ears• Eyes• Hands• Feet• Genitalia• Perineum• Major joints
![Page 15: Evaluation and Management of Burns](https://reader036.vdocuments.us/reader036/viewer/2022062315/5681600d550346895dcf0cc7/html5/thumbnails/15.jpg)
Management• Major vs
moderate/minor• Major burns should be
transferred to specialized burns centres
• Victoria:– Victorian Adult Burns
Service (VABS) at the Alfred
– Burns Unit at RCH

Victorian State Burns Service Referral Criteria
• Burns with associated inhalation injury• Burns greater than 10% total body surface area• Burns to special areas – face, hands, major joints, feet and genitals• Full thickness burns greater than 5% total body surface area• Electrical burns• Chemical burns• Circumferential burns of limbs or chest• Burns with associated trauma• Burns in the very young or elderly people• Burn injury in patients with pre-existing illness or disability that could adversely
affect patient care and outcomes• Suspected non-accidental injury in children or the elderly• Burns in children under the age of 12 months• Small area burns - in patients with social problems, including children at risk• Burns occurring in pregnant women

Major burns
• Primary survey• Assess extent of burns• Beware of circumferential full thickness burns• Analgesia• NGT insertion• Tetanus• Prevent hypothermia• Fluid resus
![Page 18: Evaluation and Management of Burns](https://reader036.vdocuments.us/reader036/viewer/2022062315/5681600d550346895dcf0cc7/html5/thumbnails/18.jpg)
Fluid Resus
• Parkland formula• Amount required in 24hrs = 4 x wt(kg) x
BSA(%)• Half in first 8hrs• Half in next 16hrs• Maintenance fluids in addition for children
weighing less than 30kg• Guided clinically and by urine output
![Page 19: Evaluation and Management of Burns](https://reader036.vdocuments.us/reader036/viewer/2022062315/5681600d550346895dcf0cc7/html5/thumbnails/19.jpg)
Minor Burns
• First aid• Cleaning burns• Blister management• Dressings• Analgesia• Tetanus• Follow up• Post burn skin care
![Page 20: Evaluation and Management of Burns](https://reader036.vdocuments.us/reader036/viewer/2022062315/5681600d550346895dcf0cc7/html5/thumbnails/20.jpg)
Electrical Burns
• Low voltage (<1000V)• High voltage (>1000V)• First aid– Turn power off– Ensure own safety
• Dysrhythmias• Compartment syndrome• Fluid resus
Full thickness exit wound to armpit post high voltage electrical burn injury

Chemical Burns• History– Type of agent– Strength and concentration– Site of contact, swallowed or inhaled– Manner and duration of contact– Mechanism of action of chemical
• First aid– Prolonged irrigation of water– Remove contaminated clothing– Brush off metals and powders– Do not attempt neutralising without specialist advice
Full thickness burns to the legs caused by kneeling in cement
