What is Burn
- A burn is an emergency and life-threatening condition that causes the destruction of the surface. A layer of the body due to exposure to thermal, chemical, electrical and radiation sources.
- Burn affects the major system of the body and causes systemic body function loss.
Cause of burn
Thermal burn –
- A thermal burn is the most common cause of burn.
- Thermal burns occur due to exposure or contact with Fire, hot liquids, flame, hot metal, flash, and stem.
Chemical burn –
- occurs due to organic and inorganic substances.
- Acidic products cause coagulative necrosis and alkaline chemicals cause colliquative necrosis.
Electrical burn –
- Electrical burn occurs due to exposure to electric current, or short circuits.
- The intensity of electrical burn depends on – the voltage mode of current and time of touch to electricity.
Other Burn –
- Inhalation burns occur due to hot smoke.
- Radiation burn occurs due to sunlight, X-Ray.
Risk factors of burne
- Hot summer
- During cooking
- Occupational hazards
- Electricity repairing.
A/C to body surface area –
Estimation of burn, on basis of body surface area. Total body surface area – 100%.
“Rule of nine ” is used to measure burn body surface area.
Rule of nine –
Rule of Nine
|Head and neck||9%|
|Upper extremities||18% (9*2)|
|Lower extremities||36% (18*2)|
|Back and chest||36% (18*2)|
According to the “Rule of nine,” an estimated burn surface area is less than 25% is indicated → mild to moderate burn.
If more than 25% burn indicates → severe burn.
Mild to Moderate Burn = 25% of body area is burned
Severe burn = more than 25% burn
Based on depth
- Superficial thickness burn
- Superficial partial thickness burn
- Deep partial thickness burn
- Full thickness burn
third degree burn
- Deep full thickness burn.
Superficial thickness burn
- Burns involve the epidermis.
- Cause – sunburn, flash, hot liquid
- Symptoms – pain, redness, tingling sensation, erythema, and swelling.
- Symptoms subside after 48 hours.
- Recovery within 3 – 7 days.
Superficial partial thickness burn
- Burns involve the epidermis and superficial areas of the dermis.
- Cause – hot liquid, cooking, steam, chemicals.
- Symptoms – blister formation, pain, redness, tenderness, pink and moist wound.
- Mild pigmentation formation and no scar formation.
- Edema present.
- Burn is sensitive to cool air.
- Burn recovery within 10 – 21 days.
Deep partial thickness burn
- Burns involve the complete epidermis and incomplete dermis skin layer.
- Cause – scalds, flash, flame
- Symptoms – No blister formation, alternative pain
- Red wound
- Dry wound with a deep white area
- Moderate edema
- Tissue necrosis
- Hypoxia and ischemia
- Scar formation.
- The recovery period is 3 – 6 weeks.
- Deep partial thickness burn requires skin grafting.
Full thickness burn
- Burn involved the complete epidermis and complete dermis layer.
- Cause – electrical current, chemical, long time exposure with hot liquid and heat, flame etc.
- Symptoms – deep red, white, yellow, Brown or black wounds.
- Dry hard eschar formation in the full-thickness burn.
- Edema will be present in full-thickness burns.
- No pain was present in the full-thickness burn.
- Loss of sensation due to nerve-ending destruction.
- Some disabilities and deformities.
- Recovery is possible by skin grafting and is dependent on months.
- An escharotomy procedure is done.
Deep full thickness burn
- Burn involves the epidermis, dermis, subcutaneous fat, muscles, organs etc.
- These types burn the bones.
- Symptoms – black open wound.
- Sensation completely absent
- Scar formation
- No pain
- Visible bone, organ, mass and vessels
- Blood leakage.
- Skin grafting (autograft) is required.
- Recovery depends months to years.
Pathophysiology of Burn
Increase capillary permeability
Excessive loss of body fluid
Decreased cardiac output

Sign and Symptom of Burn
Burn effect on Respiratory System –
- acute respiratory distress syndrome (ARDS)
- Respiratory failure
- Pulmonary edema
Burn effect on Cardiac System –
- cardiac failure
- Hypertension and shock
Burn effect on Renal System –
- oliguria and anuria
- Loss of kidney function
- Decrease GFR
- Acute kidney failure.
Burn effect on GIT-
- GI bleeding
- Peptic ulcer
- Decrease peristalsis movement
- Decrease GI perfusion.
Burn effect on Integumentary System-
- Skin loss
- Sensation loss.
- increase BMR
- Heat loss.

Burn Medical management
- Emergency / Resuscitation phase
- Resuscitative phase
- Acute phase
- Rehabilitation phase.
Emergency / Resuscitation phase of Burn
- Begins from burn to regain capillary permeability.
- Emergency / resuscitative phase 48 – 72 hours period phase.
- Include –
Burn Prehospital care
- Prehospital care from burn to when emergency care is obtained.
- Remove the source of the burn from the victim.
- Monitor ABC ( Airway, breathing and circulation )
- Physical examination and assess any trauma and injury.
- Patient cover with sterile or clear clothes.
- Remove any metal items, jewelry from the patient.
- Transfer the patient to the emergency department
Burn Emergency department care
- Monitor patient burn type, degree of burn, and site of the burn.
- ABC analysis.
- Airway clearance and administer 100% oxygen.
- Administer IV line to maintain hydration status.
- Monitor any respiratory distress and arrange intubation equipment.
- ABG analysis (arterial blood gas).
- Maintain NG tube and catheterization administration.
- Provide all prescribed medication such as – antibiotics, analgesics, TT injection, etc.
- Cover the patient with a bed cradle.
Burn Resuscitative phase
- The resuscitative phase starts from 48 hours to 72 hours.
- Start from fluid administered to capillary permeability regain.
- Administration according to the Parkland formula.
Parkland formula –
- 4ml RL * weight in kg * total burn surface area.
- Calculated half fluid administers within 8 hours and remaining half fluid administer within next 16 hours.
- The effectiveness of administration is assessed by urine output.
- Mental patient NPO and provide total parenteral nutrition.
- Administer analgesics to relieve pain.
- Escharotomy and fasciotomy procedure provide.

Acute phase starts after 48 – 72 hours.
Acute phase starts from a patient is hemodynamically stable to wound closure.

- Surgically wound cleaning and debridement
- Skin grafting ( autografting )

- Promote wound healing.
- Increase the strength of organ function.
- Minimise the complication and deformities.
Complications of burn
- Loss of body function
- Disturb body image
