Remember, Remember... Burns and Scalds

Remember, Remember... Burns and Scalds

“Remember remember the fifth of November
Gunpowder, treason and plot.
I see no reason why gunpowder, treason
Should ever be forgot...”

In the UK the 5th of November is marked by fireworks displays and so it is a good time of year to revise burns and scalds. There are several resources available on the internet, however the following will give you a good start. 

Remember: It is also worth Considering NAI as a possibilty when assessing children with burns.

Definitions/Depth of Burns

(click to enlarge)

  • Epidermal burn – skin erythema, intact skin, e.g. sunburn. Should not be calculated in the extent of the burned surface area.

  • Superficial partial thickness burn – involve epidermis and part of the papillary dermis. Is part of the % burned area. Should be left to heal by itself.

  • Deep partial thickness burn – involve epidermis, the entire papillary dermis down to reticular dermis. Is part of the % burned area. Should not be left to heal by itself, but instead be submitted to surgery.

  • Full thickness burn – involve the entire thickness of the skin and possibly subcutaneous tissue. Is part of the % burned area. No healing capacity and as such should always be submitted to surgery.

  • Full thickness burn+ – involve the entire skin and sub lying structures such as muscle or bone.

Burn Surface Area (BSA%)

Example of a Lund and Browder Chart

This should be calculated as a percentage and only include superficial partial thickness burns or deeper. Accurate assessment will have a role in fluid management, referral criteria and prognosis. Ideally a Lund-Browder chart should be used, the alternative is the rule of 9's or using the patients palm size.

A Best Bet looking at several different methods concluded "The Lund and Browder chart allows more consistent estimates of percentage surface area from drawings of burns than the Rule of Nines. No evidence was found of a benefit of one form of estimation over another in clinical practice."

Your department should have printed versions of the chart available as they also make an excellent way to document the extent of the injury in your notes.

4ml x BSA% X Weight (Kg)
— give half in the first 8 hrs and half over 16 hrs


The Parkland formula provides the current fluid management for the first 24 hours post injury and should be considered in:

  1. Adults with BSA% >15%

  2. Children with BSA% >10%

  3. Elderly (>65 yrs) with BSA% > 10%

However for some further thoughts on fluids in burns this Podcast from SMACC 2014 is worth listening to.

Remember: Consider catheterisation in the ED to allow for measurement of urine output.

Referral to a Burns Centre


Significant burns will require specialist management and the following should be referred to your Burns Centre: All burns ≥2% TBSA in children or ≥3% in adults:

  • All full thickness burns

  • All circumferential burns 

  • Any burn not healed in 2 weeks 

  • Any burn with suspicion of non-accidental injury should be referred to a Burn Unit/Centre for expert assessment within 24 hours.

In addition, the following factors should prompt a discussion with a Consultant in a specialised burn care service and consideration given to referral: 

  • All burns to hands, feet, face, perineum or genitalia 

  • Any chemical, electrical or friction burn

  • Any cold injury

  • Any unwell/febrile child with a burn 

  • Any concerns regarding burn injuries and co-morbidities that may affect treatment or healing of the burn.


Special Considerations

Airway Burns or inhalation injuries: as oedema develops there can be significant swelling and airway management can be extremely challenging - anaesthetics/ ENT should be involved and early intubation considered.

Circumferential burns: particularly around the chest as they can restrict movement and therefore ventilation, or around limbs as they can affect perfusion. Escharotomy may be required and limbs should be elevated.

Exam Material?

As a topic, burns lend themselves quite well to SAQ style exams and therefore are fair game for Part B.

Try the following:

  1. Describe the characteristics of a deep dermal burn (2 marks)
  2. Give the percentage areas associated with any two anatomical areas as part of the rule of nines (2 marks)
  3. A 100kg male has sustained 155 burns, details his fluid requirement for the first 24 hours (3 marks)
  4. Give any 6 criteria for referal to a burns centre (3 marks)
