2. Contents:- Definition of burn. Definition of scalds. Types of burn. Classification of burn. Rule of Nines. Difference between 1 st , 2 nd and 3 rd degree burn. Causes of burn and scalds. Clinical feature of burn. Management of burn. Complications of burn. Criteria of hospitalized burn patient. Agents used for burn.

3. Concepts of burn and scalds:- Burn and scalds are damage to the skin caused by heat.Both are treated in the same way. A burn is caused by dry heat-by an iron or fire. A scald is caused by something wet,such as hot water or steam.

4. Definition of burn:- According to WHO – “A burn is an injury to the skin or other organic tissue primarily caused by heat or radiation, radioactivity, electricity or chemicals as well as respiratory damage resulting from smoke inhalation are also considered to be burn”. “OR’’ A burn is the destruction of tissue by dry heat. E.g:- Fire, Acid, Electricity and so on.

5. Definition of scalds :- Scalds is a form of thermal burn injury resulted from heated fluids such as boiling water or steam.

6. Types of burns:- Thermal injury-it is due to dry heat. Electrical injury. Scald injury-it is moist heat,e.g:- hot water or steam. Chemical burns-Acid, Alkali. Cold injury-by frost. Ionizing radiation.

7. A . Depending on the percentage of burn. B. Depending on the thickness of skin involved . Classification of burns:-

8. A.Depending on the percentage of burn :- 1 . Mild burn:- Partial thickness burn <15 % in adults Or < 10% in children. 2. Moderate burn :- Second degree of 15-25 % burns in adult and 10-20% in children. *Burns which are not involving eyes, ears, feet, perineum. 3. Severe or Major burn:- Second degree burns more then 25% in adults and in children more then 20%.

9. B. Depending on the thickness of skin involved:- First-degree burns (Superficial burns): These burns affect only the outer layer of the skin, the epidermis. Symptoms include redness, minor swelling, and pain. They often heal within a week without scarring. Second-degree burns (Partial-thickness burns): These burns affect both the outer layer (epidermis) and the underlying layer of skin (dermis). Symptoms include redness, swelling, blistering, and severe pain. They may take several weeks to heal and can result in scarring.

10. Third-degree burns (Full-thickness burns): These burns extend through all layers of the skin and may also damage underlying tissues, such as muscle and bone. Symptoms may include white or blackened, charred skin, numbness due to nerve damage, and severe pain. Healing typically requires medical intervention such as skin grafts, and scarring is often significant. Fourth-degree burns: These are the most severe burns, extending beyond the skin into muscles, tendons, and even bone. Symptoms include charring, deep tissue destruction, and potentially life-threatening complications. Extensive medical treatment, including surgery and rehabilitation, is necessary for recovery.

11. Rule of nines:- Front and back of the head and neck:9% each Front and back of each arm and hand: 9% each Chest: 9% Abdomen: 9% Upper and lower back: 9% each Front and back of each leg and foot: 18% each Genital area: 1% Total=100%

12. Difference between 1 st ,2 nd and 3 rd degree burn Traits First degree Second degree Third degree 1.Depth Epithelium Epithelium and top aspects of the dermis. Epithelium and dermis 2.How the wound looks No blister,dry pink Moist,oozing bliters,moist white,pink to red. Leathery,dry,no elasticity, charred appearance. 3.Causes Sunburn,scald,flash flame. Scalds, flash burns, chemical. Contact with flame, hot surface, hot liquids,chemical,electric. 4.Pain level Painful,tender and sore. Very painful. Very little pain or no pain 5.Healing time Two to five days Superficial-5 to 21 days. Deep-21-35 days. Small areas may take months to heal;large areas need grafting. 6.Scarring No scarring, may have discoloration. Minimal to no scarring,may have discoloration. Scarring present.

13. Causes of burn :- Dry heat like fire. Contact with hot metals. Chemicals, acids, ammonia, caustic soda.. Electricity. Radiation. Flames. Lighting. Friction.

14. Causes of scalds :- Boiling water. Steam from boiling water. Any other hot liquid such as tea,coffee,hot oil e .t.c.

15. Clinical features:- Blister. Pain. Redness. Peeling skin. Swelling. Numbness or Reduced Sensation. Skin Texture Changes. White or charred skin. Wheezing. Change in voice. Difficulty in breathing. (in Inhalation Injuries) Shock.

16. Management of burn: First aid management Nursing management Medical managemen t

17. First Aid Management:- 1. Stop the burning process, patient should be removed from the source of burn and clothing should be removed. 2.Cool the area with tap water by continuous irrigation for 15-20 minutes(not too cold water which may cause hypothermia). 3.Immediately wrapped the affected area with a clean moist towel or sheet. 4.Keep the patient in a clean environment. 5.Monitoring the patients pulse, BP, respiration and urine output. 6.Do not puncture the blisters. 7.Never apply topical home remedies or creams to a newly burned area. 8.Transfer the patient to the nearest hospital.

18. Nursing Management:

19. Initial assessment:- 1. History taking: Age of the patient, time of burn, type of burn, site of burn, possibility of smoke inhalation. 2.Physical Examination: Assessment of vital signs: Pulse, blood pressure, temperature, respiratory rate. Assessment of extent of burn by rule of nines. Assessment of depth, degree of burn, partial thickness or full 1 st degree,2 nd degree,3 rd degree.

20. 3.Initial Management:- The principle of managing an acute burn injury - A=Airway control. B=Breathing and ventilation. C=Circulation. D=Disability. E=Exposure with environmental control. F=Fluid resuscitation.

21. Medical Management

22. Fluid replacement Therapy:- In 1 st 24 hours: -Crystalloid solution:-Hartman solution. Dose:-The amount of fluid volume in ml 1 st 24 hours = 3-4(ml of IV fluid)×body wt (kg)× % total burned surface area. Adult : 4ml/kg/percent of burned surface area. Child: 3ml/kg/percent of burned surface area.

23. Amount:- ½ fluid is given in 1 st 8 hours. ¼ fluid is given in 2 nd 8 hours. ¼ fluid is given in 3 rd 8 hours. In 2 nd 24 hours:- Colloid solution added with crystalloid solution. e.g : Plasma, albumin, Dextran. Dose: 0.35-1 ml/kg/percent of burned surface area.

24. Example:- If weight is 70 kg and burn is 30% Total fluid needed=4*70*30 ml=8400ml 1 st 8 hours= 4200 ml,2 nd 8 hours=2100 ml,3 rd 8 hours = 2100 ml. Antibiotic. e.g :-Flucloxacillin, Penicillin, erythromycin etc. Analgesics. e.g :-Morphine, Ibuprofen etc. Provide nutritional support. Maintain electrolyte imbalance. Administer tetanus prophylaxis if necessary. Monitor vital signs, fluid balance and urine output. Blood transfusion.

25. Local treatment:- Strict asepsis-local antiseptic cream. (1% silver sulphadiazine) Clean room with temperature 75-80F and low humidity. Dressing should be done. Skin grafting-in full thickness burn.

26. Complications of burn:- A. Immediate complications :- Shock Fluid overload Renal dysfunction Pulmonary dysfunction Hypothermia Multiple organ dysfunction Electrolyte imbalance

27. B. Delayed complications: Wound infection Delayed wound healing Hypertrophic scarring Contractures Chronic pain Septicemia Cerebral damage Failed skin graft Loss of function

28. Agents used for burn: Silver sulfadiazine 1% Mafenide acetate 5%-10% Silver nitrate 0.5% Silver- impregnated. Bismuth-impregnated petroleum gauze. Chlorhexidine. Povidone-iodine Dakin's solution.(sodium hypochlorite solution)
