Burns are injuries to the skin or other tissues caused by heat, flames, chemicals, electricity, or radiation. There are three degrees of burns - first degree involves only the outer layer of skin, second degree extends deeper into the layers of skin, and third degree burns are the most severe and destroy both the outer and deeper layers of skin. Proper burn management includes assessing the severity of the burn, giving intravenous fluids to prevent shock, cleaning and dressing the wound, providing pain medications, and carrying out surgical procedures such as excision and grafting for deep burns.

the skin or other body
parts caused by extreme
heat,flame,contact with
heated objects or
chemicals that is known
as Burn.”

6. ANATOMY & PHYSIOLOGY OF SKIN

7. According to level of severity :-
1) First degree burn :-
A first-degree burn is
the most common and least
serious burn which affects the
top layer of skin i.e. epidermis.
It causes local inflammation of
the skin & this inflammation is
characterized by pain,redness
and a mild amount of
swelling.The skin may be very
tender to touch.

9. 2) Second degree burn :-It
involve the epidermis and
the dermis.There are the
same symptoms of pain
and swelling but the skin
color is usually a bright red
and blisters are produced.
Usually second-degree
burns produce scarring.

3) THIRD DEGREE BURN

13. 4TH DEGREE
• :-The 4TH degree burn may appear patches
which appear white,brown or black.Both the
dermis and epidermis are destroyed and
other organs, tissues and bones may also be
involved.Third-degree burns are considered
the most serious

16. Etiology
1. Thermal burn injury
2. Chemical burn injury
3. Electrical burn injury
4. Radiation burn injury

17. Thermal burn
• A thermal burn is a type of burn resulting
from making contact with heated objects,
such as boiling water, steam, hot cooking oil,
fire, and hot objects.

18. Chemical burn
• A chemical burn occurs when your skin or
eyes come into contact with an irritant, such
as an acid or a base. Bases are described as
alkaline. Chemical burns are also known as
caustic burns. They may cause a reaction on
your skin or within your body.

19. Electrical burn
• An electrical burn is a burn that results from
electricity passing through the body causing
rapid injury.

20. Radiation
• A radiation burn is damage to the skin or
other biological tissue caused by exposure
to radiation. The radiation types of greatest
concern are thermal radiation, radio
frequency energy, ultraviolet light and
ionizing radiation. The most common type
of radiation burn is a sunburn caused by
UVradiation.

28. Management
- Immerse the burned area immediately in cold running
water,then dry the area gently with a clean towel .
- Cover burns with a sterile or clean,dry cloth.
- Do not prick blisters.
- Do not remove clothing adhering to the wound.
- Remove any watches,bracelets,rings,belts or constricting
clothing from the affected area before it begins to swell.
- Do not apply butter,oil or creams.
- Do not press
- Assess for associated trauma.
- Monitoring respiratory distress .
- To give oxygination .

30. Assessment & diagnostic
evaluation
1. Survey,including assessment of CIRCULATION. AIRWAY,
BREATHING as well as vital signs is done.
2. Effected of burns areas is determined by :
• Depth :-First,Second & Third degree burn injury
• Extent :- % of total body surface area (TBSA)
• Age :- The very young & very old have a poor prognosis.
• Area of the body burned :- face,hands,feet,perineum &
circumferential burns require special care.
• Medical history.
• Inhalation injury.
3. Obtain arterial blood gas & carboxyhemoglobin

31. CIRCULATION. AIRWAY, BREATHING
- The circulatory system must also be assessed
quickly.
- Apical pulse & Blood pressure are monitores.
- The neurologic status is assessed quickly in pt
with extensive burns.
- A head to toe survey of the pt is carried out to
identify other potentially life threatening injuries.
- Usually,rescue workers will cool the
wound,establish an airway,supply O2 & insert at
least one large-bore intravenous line.

32. - Immediate I.V. fluid resuscitation is indicated for :
- Adults with burns involving more than 18-20% of
TBSA % Children with more than 12-15% of TBSA.
- Generally a crystalloid solution (Ringer’s lactate)
is used initially.
- Colloid is used during the second day
- One of several formulas may be used to
determine the amount of fluid to be given in the
first 48 hrs.

37. 4.PARKLAND/BAXTER
FORMULA

38. (i) First 24 hrs. :- 4 ml of ringer’s lactate × kg body wt × % TBSA
burned.
(ii) One half amount of fluid is given in the first 8 hrs.calculated from
the time of injury. If the starting of fluid is delayed, then the same
amount of fluid is given over the remaining time.
(iii) The remaining half of the fluid is given over the next 16 hrs.
Example :- Patient’s weight :- 70 kg, %TBSA burn :- 80%
4 ml × 70 kg ×80% TBSA
= 22,400 ml of Ringer’s lactate
First 8 hrs. :- 11,200 ml or 1,400 ml/hr. (11200 /8 = 1400ml/hr )
Second 16 hrs. :- 11,200 ml or 700 ml/hr (11200/16 = 700 ml/hr )

39. CON……..
(2) Second 24 hrs. :-
0.5 ml colloid × kg body wt × % TBSA
GLUCOSE (5%D) 2000 ml dextrose 5% for water
insensible over the 24 hrs period.
Example :- 0.5 ml × 70 kg × 80%+ D 5 2000 ML
= 2,800 ml colloid + D 5 2000 ML
First 8 hrs. :- 1400 /8 = 175 ML colloid /HR
Second 16 hrs. :- 1400 /16 =87.5 ML Colloid /HR
continue 2000 ml D5 all insensible water loss

40. 4) Emergency medical management :-
- A large bore intravenous catheter should be inserted.
- Most pts have a central venous catheter inserted so that
large amounts of I V fluids can be given quickly.
- Pt. to protect the area from contamination.
- Burns are contaminated wounds,tetanus prophylaxis is
administered.
- Only intravenous pain medication usually morphine is
given.
- Topical antimicrobial agents includes silver
sulfadiazine,silver nitrate(0.5% solution),mafenide
acetate (10% cream or 5% solution) etc.
- Dressing may take may form of commercial
multilayered pads,standard 4×4 gauze pads.

41. - Daily or twice daily wound cleansing with
debridement or hydrotherapy & dressing
changes.
- Early excision of deep second & third degree
burns is the goal.
- Burn wounds must be cleansed initially & usually
daily with a mild antibacterial cleansing agent &
saline solution or water.

52. BIOBRANE
• (a type of artificial skin) is a
man made skin substitute composed
of nylon mesh, silicone and collagen
(derived from pig skin). It is a stretchable
dressing that is used as a temporary cover
for clean partial thickness burns and
donor sites or as a protective covering
over meshed skin grafts.

54. • INTEGRA
• is a product that is used to help re-grow
skin on body parts where skin has been
removed or badly damaged. It was
initially used to safely cover large areas
of burned tissue where skin needed to be
regrown. However, Integra is now used
far more widely as part of skin grafts in
reconstructive surgery.

56. CALCIUM ALGINATE DRESSING
uses is to provide homeostasis, calcium
alginate is more commonly thought of as
the dressing that can absorb 20 times its
weight in exudate, soak up loose debris
from the wound bed, provide an optimal
environment for healing, and provide a
painless dressing change.

58. •Vaseline Gauze – Fine
mesh gauze which is non-
adherent to wound sites
and helps maintain a moist
wound environment.

59. Surgical managemenT
- The basic goal is the early excision & grafting.
1. Tangential Excision :-A special blade is used to
slice off thin layers ( 0.5 mm thick ) of damaged
skin until live tissue is evidenced by capillary
bleeding.Commonly used with deep partial
thickness burns & followed with immediate
dressing. Appling to deep dermal burns 3rd
degree burns .
2. Fascial (Primary) Excision :- The skin,lymphatics
& subcutaneous tissue are removed down to
fascia with either immediate autografting or
temporary coverage with biologic dressings.

60. ESCHAROTOMY
• is a surgical procedure used to treat full
thickness burn circumferential burn . In full
thickness burn ,both the dermis and
epidermis layer are destroyed along with
sensory nerve in the dermis .
