Definition & Types
Definition
A burn is a thermal injury caused by biological, chemical,
electrical and physical agents with local and systemic
effects
Etiology
Thermal injury
Chemical burns
Cold injury
Ionising radiation
Sun burns
5. 08/08/2024 DR KAPAMBWE CHRISPINE D 5
Classification
Superficial (first degree)
Partial thickness (second degree)
1) Superficial partial
2) Deep partial
Full thickness (third degree)
6. 08/08/2024 DR KAPAMBWE CHRISPINE D 6
Pathophysiology
Burns induce local and systemic damage that seriously
alter homeostasis.
Local
1. Zone of coagulation
2. Zone stasis
3. Zone of hyperemia
Systemic
Systemic changes depend on the affected body surface
(usually greater than 10%).
Present according to the affected system.

MANAGEMENT 1
Burn management is conducted by members of a multidisciplinary burn
team which include medical, surgical, intensive care, nursing,
physiotherapy, occupational therapy, diatetics, social work, psychiatry, ,
speech therapy, .
Serious burn requiring hospitalization
Greater than 15% burns in an adult
Greater than 10% burns in a child
Any burn in the very young, the elderly 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

Management 2
1) First aid
Stop the burning process
Cool the area with tap water

2)Definitive
Admit the patient.
Do ABCDE
Determine percentage, degree and type of burn
IV access and early fluid replacement.
Investigations
Medication
Other care

Management cont...
Fluid replacements
a) Barclay & Muir formula or Leads formula:
Body wt. x TBSA%/2 = Xmls
b) Parkland formula:
Body wt x TBSA% x (1-4mls) = X mls
14. 08/08/2024 DR KAPAMBWE CHRISPINE D 14
Parkland formula:
Body wt x TBSA% x (1-4mls) = X mls
-1st give half of Xmls in the 1st 8hrs from time of
burns event
-2nd give next half of Xmls in the next 16hrs
The fluids used are Crystalloids, N-saline, Ringers
lactate or Hartmanns
solution
TBSA>15%: blood transfusion after 24 hours (pediatrics)
TBSA>20%: blood transfusion (adults)

Medications
Tetanus toxoid 0.5mls IM-single dose
Topical Antibacterial agents - Silver
Sulphadiazine,Povidone cream or Chloherxidine
cream for those allergic to sulfur containing
medication.
Antibiotics if burns are infected depending on the
sensivity tests of the centre.
Haematinics to boost blood levels.
Analgesia
Others care
