Burns are a leading cause of accidental pediatric injuries and deaths worldwide. Scalding from hot liquids is the most common cause of burns in children, often related to cooking practices. Initial management involves fluid resuscitation, antibiotics, dressings, and nutrition to support wound healing. Complications can include disfigurement, contractures, and emotional trauma. Ultimately, decreasing the burden of pediatric burns requires prevention through education, legislation, and environmental modifications.

Burns In The Pediatric Population

3. Definition
A burn is a type of injury to the flesh or skin
caused by heat, electricity, chemical, friction or
radiation
4. Incidence
One of the leading causes of accidental injuries
at home.
5th most common cause of accidental death in
children
Hot tap water burns cause more deaths and
hospitalizations than burns from any other hot
liquids.
7. Contributing Factors
Socio-economics
- children from low income homes have 8x a risk of
sustaining burns than those from higher income
homes
- severity of burns inversely proportional to
decreasing SES
- burn mortality is higher among children from
lower SES
8. Living Conditions
- children are naturally curious, impulsive and
active,increases risk of burns
- flammable and caustic substances stored in the
home
- heating with indoor fires
- cooking practices;
NB. 2 billion people worldwide cook with open flames or unsafe traditional
stoves
9. - lack of adult supervision
- overcrowding
Medical conditions
-Epilepsy
* Increase risk of fall
* Traditional medicine practices; eg. The
deliberate burning of feet to rouse the child
from convulsive state.
10. Child Abuse
Burns account for 10% of all cases of child
abuse
Majority of victims are < 2 years of age
Scalding is the most common cause
11. Suspicion of child abuse
Burns to:
Perineum
Ankles
Wrists
Palms
Soles
Burns with clean line of demarcation
Presence of older injuries
Contradictory accounts of accident
Delays in seeking treatment
12. Pathophysiology
According to Jacksons Thermal wound theory, there are
three zones associated with burn injuries:
Zone of Coagulation
- area closest to the wound
- ruptured cell membranes, clotted blood & thrombosed
vessels
Zone of Stasis
- area around zone of coagulation
- inflammation & decreased blood flow
Zone of Hyperemia
- peripheral area of the wound
- limited inflammation & increased blood flow
15. Criteria for admission
Greater than 10% burns in a child
Any burn in the very young or the infirm
Any full thickness burn
Burns of special regions: face, hands, feet, perineum
Circumferential burns
Inhalation injury
Associated trauma or significant pre-burn illness: e.g. diabetes
18. Management
ABC
Intubate and mechanically ventilate if you suspect
inhalation injury
Quickly establish IV access (ideally 2 large bore IVs)
Evaluate for compartment syndrome, particularly with
circumferential burns
19. Assessing inhalation injury
Look for:
Singed facial hairs
Edema of nose, mouth, pharynx and larynx
Carbonaceous sputum
Hoarseness
Stridor
20. Fluid Resuscitation
Restoring adequate intravascular volume to
prevent hypotension and shock
Correcting electrolyte abnormalities
Minimize renal insufficiency
If burns >15%
Massive fluid shifts will likely occur due to
systemic inflammatory response syndrome (SIRS)
Fluid needs will be greater than anticipated
based on appearance of burn alone
21. Parkland formula:
3-4 ml x kg x % total burn surface area (TBSA)
12 in first 8 hours
Remaining in next 16 hours
Galveston Shriners formula
5000 mL/m2 TBSA burn + 2000 mL/m2 body
surface area (BSA)
22. Fluid: Lactate Ringer
plus 12.5 g 25% albumin per L
plus D5W as needed for hypoglycemia
Remember to monitor glucose levels
Glycogen stores of children <5 y/o run out
quickly
Inhalation injury increases fluid requirements
by 1.1 ml/kg/% TBSA
Goal of fluid resuscitation = Adequate urine
output (1-1.5ml/kg/hr)
23. Muir & Barclay Formula
TBSA % x weight (kg) = volume (mls) fluid need
per period.
The volume needs to be recalculated at each
change in time period:
Every four hours for the first 12 hours;
Every six hours between 12 and 24 hours;
After 36 hours.
24. Dressings
Topical antibiotic:
Silver nitrate
Cheap
Does not penetrate eschar
Depletes electrolytes
Silver sulfadiazine
Some penetration of eschar
Risk of neutropenia
Mafenide acetate
Penetrates eschar
Risk of developing acidosis
25. Nutrition
Burns lead to increased metabolic demands and
energy requirements
For burns >40%, resting metabolic rate increases
up to 200%
Primarily protein catabolism
* Protein requirement increased to 2.0 g/kg/day
Without adequate nutrition wound healing will
not occur
26. Goal: Loss of less than 10% of preinjury weight
Patients should be weighed daily
Enteral feeds are superior to parenteral
Feed child orally if possible
Otherwise place nasogastric feeding tube
28. Complications
Disfigurement
Contractures
Lead to severe disability in many cases
Emotional damage/sequelae
Delay in reaching developmental milestones and
educational development
Death
29. Summary
Burns account for a significant proportion of pediatric
morbidity and mortality worldwide, particularly in LSES.
Majority of burns are due to fire or scalding, often related
to cooking practices.
Initial evaluation should always include an assessment for
child abuse.
Ultimately, the key to decreasing morbidity and mortality
associated with burns is prevention via...
Educational campaigns
Legislative changes
Hazard reduction and environmental modification

Editor's Notes
#20: Can occur without skin burns
Carbonaceous sputum burned saliva
#24: this uses a colloid resuscitation with plasma and runs over 36 hours.
As the fluid lost from the circulation is plasma, it seems logical to replace it with plasma. With colloid resuscitation, less volume is required and the blood pressure is better supported.
However, both colloid and plasma are expensive. They may also leak out of the circulation and may result in oedema of the lungs.
The 36 hours are divided into six periods of varying length, and an equal volume of plasma is administered in each period. The volume to be transfused in each period is calculated via the formula. This volume is given in each successive period of four, four, four, six, six and 12 hours. At the end of a period, if the assessment shows that the patients clinical condition is stable, the transfusion is continued according to the formula. If there is any clinical evidence of under- or overtransfusion then the plasma rations for the next and following periods are altered accordingly.
#25: Silver sulph ( broad spec prophylaxis against pseudomonas and methicillin resistant stap aureus)
Silver nitrate ( not active against some gram ve aerobes and need to be reapplied ever 2-4hrs)
Mafenide cream ( painful to apply, associated with metabolic acidosis)
