  • 1. Burn Training Assessment & Management Dr. D. N. Bid
  • 2. Contents
    • ▪ Anatomy of Integumentary System Review
    • ▪ Determining Severity of Burn
    • ▪ Assessment
    • ▪ Management
    • ▪ Transfer to Burn Center
  • 3. Anatomy of the Integumentary System (Skin)
    • Skin covers ~ 1.5-2.0 square meters in the average adult
    • ▪ Largest organ of the body
    • ▪ Two principal layers
    • -Epidermis
    • -Dermis
  • 4. Subcutaneous Tissue
    • Contains major vesicular networks, fat, nerves,
    • and lymphatics
    • Acts as a shock absorber and heat insulator for underlying structures of muscles, tendons, bones, and internal organs
  • 5. Anatomy of the Skin
  • 6. Anatomy of the Skin
  • 7. Function of the Skin
    • Protection
      • Against external forces
      • Against infection
    • Sensation
      • Nerves report touch & status in environment
    • Temperature control
      • Blood vessel dilation/constriction
      • Sweat evaporates
  • 8. Burn wounds occur when there is contact between tissue and an energy source such as - heat (thermal) - chemicals - electrical current - radiation
  • 9. Extent of burns are influenced by
    • intensity of the energy
    • duration of exposure
    • type of tissue injured
  • 10. Zones of Burn Injury
    • Zone of coagulation - This occurs at the point of maximum damage. In this zone there is irreversible tissue loss due to coagulation of the constituent proteins.
    • Zone of stasis - The surrounding zone is characterized by decreased tissue perfusion. The tissue in this zone is potentially salvageable. The main aim of burns resuscitation is to increase tissue perfusion here and prevent any damage becoming irreversible. Additional insults—such as prolonged hypotension, infection, or edema—can convert this zone into an area of complete tissue loss.
    • Zone of hyperemia - In this outermost zone tissue perfusion is increased. The tissue here will invariably recover unless there is severe sepsis or prolonged hypoperfusion.
  • 11. Zones of Burn Injury
  • 12. Zones of Burn Injury Clinical image of burn zones. There is central necrosis, surrounded by the zones of stasis and of hyperemia
  • 13.  
  • 14. Depth of Burns
    • Superficial (first-degree) burns
    • Involve only top skin layer
  • 15. Superficial - First degree burns
    • Epidermis only damaged
    • Painful to touch
    • Area initially erythematous due to vasodilatation
    • Epidermis sloughed off in 7 days with complete scarless healing
  • 16. Depth of Burns
    • Partial-thickness (second-degree) burns
    • Involve epidermis and some portion of dermis
    • Can be either
    • superficial or deep
  • 17. Partial thickness – Superficial Second degree burns
    • Epidermis & various degrees of dermis destroyed
    • Are pink to cherry red and wet
    • May or may not have intact blisters and are very painful when touched or exposed to air
    • Heal in 7-14 days with topical antimicrobials or wound dressings
  • 18. Partial thickness – Superficial Second degree burns
  • 19. Partial thickness – Deep Second degree burns
    • Epidermis & deeper degrees of dermis destroyed
    • Are pink to cherry red, wet, shiny with serous exudate
    • Very painful when touched or exposed to air
    • Heal in 14- 28 days with scarring
    • May need early excision and grafting
  • 20. Partial Thickness-Deep Second degree burns
  • 21. Depth of Burns
    • Full-thickness (third-degree) burns
    • Extend through all layers of skin
    Need better phtls
  • 22.
    • Will appear as thick, dry, leathery, waxy white to dark brown regardless of race or skin color
    • May have a charred appearance with visible thrombosis of blood vessels
    • Will have little to no sensation because nerve endings have been destroyed except in surrounding tissues with partial thickness burns
    Full-thickness – Third degree burns
  • 23. Full Thickness-Third degree burns
  • 24. Depth of Burns
    • Fourth-degree burns
    • Extend through all layers of skin as well as extending to underlying fat, muscle, bone or internal organs
    Need better phtls Fig 13-7
  • 25. Burn Size Estimation
    • Critical to providing adequate resuscitation
    • 3 common guidelines used
      • Rule of Nines
      • Lund-Browder Chart
      • Palmer Method
  • 26. Rule of Nines
    • In the adult, most areas of the body can be divided roughly into portions of 9% or multiples of 9.
    • In the child, similar portions are assigned
    • This division is useful in estimating the percentage of body surface damage an individual has sustained in burn.
  • 27. Rule of Nines
  • 28. Lund-Browder Chart
  • 29. Palmer Method
    • The palmer surface of the patient’s hand –from crease at wrist to tip of extended fingers- equals ~ 1% of the patient’s total body surface area
  • 30. Severity of Burn Injury
    • Treatment of burns is directly related to the severity of injury
    • Severity is determined by
      • depth of burn
      • external of burn calculated in percent of total body surface (TBSA)
      • location of burn
      • patient risk factors
  • 31. Minor Burns
    • Full-thickness burns involving less than 2% of the total body surface area
    • Partial-thickness burns covering less than 15% of the total body surface area
    • Superficial burns covering less than 50% of the total body surface area
  • 32. Moderate Burns
    • Full-thickness burns involving 2% to 10% of total body surface area excluding hands, feet, face, upper airway, or genitalia
    • Partial-thickness burns covering 15% to 30% of total body surface area
    • Superficial burns covering more than 50% of total body surface area
  • 33. Critical Burns (1 of 2)
    • Full-thickness burns involving hands, feet, face, upper airway, genitalia, or circumferential burns of other areas
    • Full-thickness burns covering more than 10% of total body surface area
    • Partial-thickness burns covering more than 30% of total body surface area
    • Burns associated with respiratory injury
  • 34. Critical Burns (2 of 2)
    • Burns complicated by fractures
    • Burns on patients younger than 5 years old or older than 55 years old that would be classified as moderate on young adults
  • 35. Pediatric Needs
    • Burns to children are considered more serious than burns to adults.
    • Children have more surface area relative to body mass than adults.
  • 36. Minor Burns in Infants and Children
    • Partial-thickness burns covering less than 10% of total body surface area
  • 37. Moderate Burns in Infants and Children
    • Partial-thickness burns covering 10% to 20% of total body surface area
  • 38. Critical Burns in Infants and Children
    • Full-thickness burns covering more than 20% of total body surface area
    • Burns involving hands, feet, face, upper airway, genitalia
  • 39. Location of Burns
    • Has a direct relationship to the severity of the burn.
    • Face, neck & chest burns may inhibit respiratory illness RT mechanical obstruction secondary to edema or eschar formation
  • 40. Patient Risk Factors
    • Older adults heals slower & has more difficulty with rehab
    • common complications are:
      • infection & pneumonia
      • preexisting illnesses: cardiovascular, pulmonary, or renal disease
      • DM or PVD is at increased risk for gangrene & poor healing
  • 41. Types of Burn Injury
    • Thermal Burn -can be caused by flame, flash, scald, or contact with hot objects
    • Chemical Burn -are the result of tissue injury and destruction from necrotizing substances
    • Electrical Burn- results from coagulation necrosis that is caused by intense heat from an electrical current
    • Smoke & inhalation injury- inhaling hot air or noxious chemicals
    • Radiation Burn/Exposure- burns are usually localized & are indicative of high radiation doses to affected area
  • 42. Thermal Burns
    • most common type
    • result from residential fires, automobile accidents, playing with matches, improperly stored gasoline, space heaters, electrical malfunctions, arson, terrorism
    • inhaling smoke, steam, dry heat (fire), wet heat (steam), radiation, sun, etc...
  • 43. Thermal Burns
    • Thermal burns cause a number of effects described in the ‘Zones of injury”
  • 44. Chemical Burn
    • 2 types of chemical burns
    • acids- can be neutralized
    • alkaline - adheres to tissue, causing protein hydrolyses and liquefaction
      • examples: industrial or agricultural sites, highways and battlefields > cleaning agents, drain cleaners, lyes, and military grade agents, etc.
  • 45. Chemical Burn
    • With chemical burns, tissue destruction may continue for up to 72 hours afterwards.
    • It is important to remove the person from the burning agent or vice versa.
    • Chemicals, heat, and light rays can burn the eye.
  • 46. Electrical Burns
    • Injury from electrical burns results from coagulation necrosis that is caused by intense heat generated from an electric current.
    • Can cause tissue anoxia and death
    • The severity depends on amount of voltage, tissue resistance, current pathways, and surface area in contact with the current and length of time the current flow was sustained.
  • 47. External signs of an electrical burn may be deceiving. Entrance may be small, while deeper tissue damage may be massive.
  • 48. Electrical injury can cause:
    • Fractures of long bones and vertebra
    • Cardiac arrest or arrhythmias--can be delayed 24-48 hours after injury
    • Severe metabolic acidosis--can develop in minutes
    • Myoglobinuria--acute renal tubular necrosis- myoglobin released from muscle tissue whenever massive muscle damage occurs--goes to kidneys--and can mechanically block the renal tubules due to the large size!
  • 49. Electricity can instantaneously destroy tissue. This child has a burn that resulted from biting on an electrical cord. These burns often occur at the corners of the mouth, as seen here.
  • 50. Smoke and Inhalation Injury
    • Can damage the tissues of the respiratory tract
    • Although damage to the respiratory mucosa can occur, it seldom happens because the vocal cords and glottis closes as a protective mechanisms.
  • 51.  
  • 52. The glottis (1) is the opening in the epiglottis (2). It is the dark slit in the center of the epiglottis and is evident when the tongue is pulled down toward the chest cavity.
  • 53. Inhalation injury Airway edema & Carbon deposits
  • 54. 3 types of smoke and inhalation injuries
    • 1. Carbon monoxide poisoning (CO poisoning and asphyxiation count for majority of deaths)
      • Treatment- 100% humidified oxygen-draw carboxyhemoglobin level- can occur without any burn injury to the skin
  • 55.
    • 2. Inhalation injury above the glottis (caused by inhaling hot air, steam, or smoke.)
      • Mechanical obstruction can occur quickly-True ER! Watch for facial burns, signed nasal hair, hoarseness, painful swallowing, and darkened oral or nasal membranes
  • 56.
    • 3 . Inhalation injury below glottis
      • (above glottis-injury is thermally produced)
      • below glottis-it is usually chemically produced.
      • Amount of damage related to length of exposure to smoke or toxic fumes
      • Can appear 12-24 hours after burn
  • 57. Radiation Burn/Exposure
    • The typical exposure to radiation occurs in an industrial or occupational setting
    • With increasing threat of global terrorism, the detonation of a nuclear device is a possibility
  • 58. Radiation Burn/Exposure
    • Detonation of a nuclear weapon would injure/kill by three mechanisms
      • Thermal burns from initial firestorm
      • Supersonic destructive blast
      • Radiation
      • Mortality from a combination of thermal & radiation burns is greater than that from thermal or radiation burns of equal magnitude
  • 59. Radiation Burn/Exposure
    • Physiologic consequence signs/symptoms of whole-body radiation appear within hours of exposure
    • Cells of the body that are most sensitive to radiation are typically those the undergo rapid division
      • GI tract
      • Bone marrow
  • 60. 3 Phases of Burn Management
      • Emergent (resuscitation)
        • 0 – 48 hours, can be up to days later
      • Acute (definitive care)
        • ▪ day 3 until wounds heal
      • Rehabilitation
        • Begins during resuscitation and continues throughout lifespan
  • 61. Emergent Phase (Resuscitative Phase)
    • Lasts from onset to 5 or more days but usually lasts 24-48 hours
    • Begins with fluid loss and edema formation and continues until fluid motorization and diuresis begins
    • Greatest initial threat is hypovolemic shock to a major burn patient
  • 62. Emergent Phase – Initial Management/Care
    • Remove patient from area! Stop the burn!
    • Airway- check for patency, soot around nares, or signed nasal hair. 100% O2 via NRM @ 15L. Watch for early upper airway edema >intubate is in doubt.
    • Breathing - check for adequacy of ventilation, consider need for early intubation or early escharotomy if ventilation is impaired
  • 63. Emergent Phase –Initial Management/Care
    • Circulation- check for presence and regularity of pulses, consider early escharotomy if circulation to a limb is impaired
    • Disability- AVPU, altered mental status in burn patient is not normal >think carbon monoxide poisoning. Check pupils. Check for movement in all extremities.
    • Expose- Remove clothing and jewelry. Do not pull on clothing stuck to skin > Cut away clothing or soak it off. Cover with dry sterile sheet and tuck in sides.
  • 64. Emergent Phase –Initial Management/Care
    • Fluid Resuscitation- estimate TBSA burn percentage and weight then calculate fluids for first 24 hour period using Parkland formula
    • Foley catheter- to monitor urine output
    • Secondary survey starting with a good scene and patient history then head to toe exam
    • Pain Management- early and often based on patient’s hemodynamic status and pain scale
    • Psychosocial issues- consider need for religious intervention, legal consult for family affairs, etc for patients with life-threatening burns
  • 65. Secondary Survey History
    • Flame
    • How did the burn occur? Did the burn occur outside or inside? Did the clothes catch on fire? How long did it take to extinguish the flames? How were the flames extinguished? Was gasoline or another fuel involved? Was there an explosion? Was there a building/house fire? Was the patient found in a smoke-filled room? How did the patient escape? If the patient jumped out a window, from what floor? Were others killed at the scene? Was there a motor vehicle crash? How badly was the vehicle damaged? Was there a motor vehicle fire? Are there other injuries? Are the purported circumstances of the injury consistent with the burn characteristics?
  • 66. Secondary Survey History
    • Chemical
    • What was the agent? How did the exposure occur? What was the duration of contact? What decontamination occurred? Was there an explosion?
  • 67. Secondary Survey History
    • Electrical
    • What kind of electricity was involved? What was the duration of contact? Did the patient fall? What was the estimated voltage? Was there loss of consciousness? Was cardiopulmonary resuscitation administered at the scene?
  • 68. Specific burn –Treatment notes Care for Thermal Burn
      • For <10% TBSA burn-apply moist cool sterile dressings to small burn
      • For larger-cover area with dry sterile dressings or sheet
  • 69. Specific burn –Treatment notes Care for Chemical Burn (1 of 2)
    • Remove the chemical from the patient.
    • If it is a powder chemical, brush off first.
    • Remove all contaminated clothing.
  • 70. Care for Chemical Burn (2 of 2)
    • Flush burned area with large amounts of water for 30 minutes or more.
    • Transport quickly .
  • 71. Chemical Burn- Eyes
    • Occur whenever a toxic substance contacts the body
    • Eyes are particularly vulnerable.
    • Fumes can cause burns.
    • To prevent exposure, wear appropriate gloves and eye protection.
  • 72. Chemical Burn- Eyes
    • For chemicals, flush eye with saline solution or clean water.
    • You may have to force eye open to get enough irrigation to eye.
    • With an alkali or strong acid burn, irrigate eye for about 20 minutes.
    • Bandage eye with dry dressing.
  • 73. Irrigating the Eye
  • 74. Specific burn –Treatment notes Care for Electrical Burn
    • Cardiac Monitor
    • Fluids -Ringers Lactate or other fluids to flush kidneys if myoglobinuria is present
    • Assess for bone fractures and treat appropriately if found
  • 75. Complications during emergent phase of burn injury may occur in 3 major organ systems
      • Cardiovascular
      • Respiratory
      • Renal
  • 76. Cardiovascular System
    • Arrhythmias, hypovolemic shock which may lead to irreversible shock
    • Circulation to limbs can be impaired by circumferential burns and then the edema formation
    • Causes: occluded blood supply thus causing ischemia, necrosis, and eventually gangrene
    • Escharotomies (incisions through eschar) done to restore circulation to compromised extremities
  • 77. Respiratory System
    • Vulnerable to 2 types of injury
      • 1. Upper airway burns that cause edema formation & obstruction of the airway
      • 2. Inhalation injury can show up 24 hrs later-watch for respiratory distress such as increased agitation or change in rate or character of respirations
      • preexisting problem (ex. COPD) more prone to get respiratory infection
        • Pneumonia is common complication of major burns
        • Is possible to overload with fluids--leading to pulmonary edema
  • 78. Renal System
    • Most common renal complication of burns in the emergent phase is Acute Tubular Necrosis (ATN) (muscle destruction > myoglobulin release > protein leak clogs kidney cells >ischemia) Because of hypovolemic state, blood flow decreases, causing renal ischemia. If it continues, acute renal failure may develop.
  • 79. Patient management in the Emergent Phase
    • Airway management -early nasotracheal or endotracheal intubation before airway is actually compromised (usually 1-2 hours after burn)
    • Ventilator - ABGs - Escharotomies
    • Bronchoscopy to assess lower respiratory tract
    • 6-12 hours later
    • High Fowler’s position-cough & deep breathe every hour, turn q 1-2 hrs, chest physiotherapy, suction prn
  • 80. Fluid Shifts
    • Massive fluid shifts out of blood vessels as a result of increased capillary permeability. When capillary walls become more permeable, water, sodium, and later plasma protein (esp. albumin) moves into interstitial spaces & other tissues. The colloidal osmotic pressure decreases with loss of protein from the vascular space. This called second spacing.
  • 81. Third Spacing
    • Fluids goes into areas with no fluids and this is called third spacing. Examples of third spacing are exudate and blister formation
    • Net result is decreased volume, depletion due to fluid shifts = edema, decreased blood pressure, and increased pulse
  • 82. Hypovolemic Shock
    • Occurs when there is a loss of intravascular fluid volume. The volume is inadequate to fill vascular space and is unavailable for circulation
    • Burns have a direct loss of fluid due to evaporation
  • 83. Fluid Therapy
    • 1 or 2 large bore IV replacement lines (may need jugular or subclavian)
    • Cutdowns are rare due to increased risk of infection & sepsis
    • Fluid replacement based on: size/depth of burn, age of pt., & individualized considerations--ex. Dehydration in preburn state, chronic illness
    • Options- RL, D5NS, dextam, albumin, etc.
    • Parkland formula to determine adequate amount to give
  • 84. Parkland Formula
    • Lactated Ringers solution is recommended 3ml/kg/%TBSA burn = ml’s in first 24 hours
      • ½ of this total given in the first 8 hours post injury
      • remaining ½ given in the next 16 hours.
      • Titrate to maintain urinary output as well.
  • 85. Example - 50 kg patient with 50% TBSA burn
    • 3 ml/kg/%TBSA burn
    • 3 (ml) x 50 (kg) x 50 (%TBSA) = 7500 ml in first 24 hrs
    • give 3750 ml in first 8 hrs @ 469 ml/hr
    • give 3750 ml in next 16 hrs @ 234 ml/hr
  • 86. Pediatric Consideration
    • In children <30kg also administer D5 ½ LR solution @ maintenance rate of:
    • For the first 1 to 10 kg - 100ml/kg/24 hours = 4ml/kg/hour
    • For the second 11 to 20 kg - 50ml/kg/24hours = 2ml/kg/hour
    • For any weight 21 to 30 kg - 20ml/kg/24hours = 1ml/kg/hour
  • 87. Pediatric Consideration
    • Example for a 12 kg child:
      • 100 ml/kg for first 10 kg 10 kg x 100 ml = 1000ml
      • 50 ml/kg for each kg between 11 and 20kg 2 kg x 50 ml = 100ml
      • 20 ml/kg for each kg between 21 and 30 kg --- none needed ----
            • =1100ml/24hours
            • Do not give dextrose solutions (except for maintenance fluids in children)- they may cause an osmotic diuresis and confuse adequacy of resuscitation assessment.
  • 88. Assessment of adequacy of fluid replacement
    • Urinary output is most commonly used parameter
      • Adequate urine output is 30 ml/hr in adults and
      • 1 ml/kg/hr in a child less than 30 kg
      • Cardiopulmonary factors- BP (systolic 90-100 mmHg), pulse less than 100, resp 16-20 breaths per min. (BP more accurate with arterial line)
    • Sensoruim-alert, oriented to time, place, & person
  • 89. Inflammation & Healing
    • Burn injuries cause coagulation necrosis whereby tissues and vessels are damaged or destroyed
    • Wound repair begins within the first 6-12 hours after injury.
  • 90. Immunologic Changes
    • Are caused by burns
    • Skin barrier destroyed and all changes make the burn patient more susceptible to infection
    • Patient may be in shock from pain and hypovolemia
  • 91. Considerations (1 of 2)
    • Full-thickness burns and deep partial thickness burns are initially anesthetic because nerve endings are destroyed
    • Superficial to moderate partial thickness burns are very painful
  • 92. Considerations (2 of 2)
    • Severe dehydration is possible even though the patient may be edematous
    • May have an dynamic ileus due to body’s response to massive trauma and potassium shifts
    • Shivering due to chilling caused by heat loss, anxiety, and pain
    • Patient unable to recall events due to hypoxia associated with smoke inhalation, or head trauma or overdose of sedatives or pain meds
  • 93. Wound Care for Burns
    • Can wait until patent airway, adequate circulation, fluid replacement is assured
  • 94. Cleansing and Debridement
    • Can be done in tank, shower, or bed
    • Debridement may be done in surgery (Loose necrotic skin is removed)
    • Bath given with with surgical detergent, disinfectant, or cleansing agent to reduce pathogenic organisms
  • 95. Infection is the most serious threat to further tissue injury and possible sepsis
    • SURVIVAL is related to prevention of wound contamination
      • Source of infection is pt’s own flora, predominantly from the skin, resp. tract, and GI tract
      • Prevention of cross contamination from other patients is the priority for patient care staff
  • 96. Wound Management Methods
    • Open method - pt’s burn is covered with a topical antibiotic and has no dressing
    • Closed method- uses sterile gauze impregnated with or laid over a topical antibiotic. Dressings changed 2-3 times q 24 hrs.
  • 97. Wound Care
    • Staff should wear disposable hats, gowns, gloves, masks when wounds are exposed
    • Appropriate use of aseptic- sterile vs. nonsterile techniques
    • Keep room warm
    • Careful handwashing
    • Disinfect patient bathing areas before and after bathing
  • 98.
    • Coverage is the primary goal for burn wounds. There is usually not enough unburned skin for immediate skin grafting, other temporary wound closure methods are used
      • Allograph or homograft (same species which is usually from cadavers) is used for wound closure-- temporary--3 days to 2 wks
      • Porcine skin-heterograft or xenograft (different species)--temporary--3 days to 2 wks
      • autograft or cultured epithelial autograft- (pt’s own skin and cell culture)- permanent
  • 99. Surgeons use a dermatome (left) to remove donor skin and a mesher (right) to put holes in it.
  • 100.
    • Surgeons agree that no single product or technique is right for every burn situation.
    • There is no true replacement for healthy, intact skin, which is the body's largest organ, and one of the most complex
  • 101. Example of healing burn
  • 102. Other care measures
    • Face is vascular and subject to increased edema- use open method if possible to decrease confusion and disorientation
    • Eye care-use saline rinses, artificial tears
    • Hands &arms-extended and elevated on pillows or in slings to minimize edema, may need splints to keep them in functional positions
  • 103.
    • Ears- keep free of pressure –use no pillows Neck burns should not use pillows in order to decrease wound contraction
    • Perineum- must be kept clean & dry Indwelling Foley will help in this & provide hourly outputs
    • Lab tests
      • Baseline studies: hematocrit, electrolytes, blood urea nitrogen, urinalysis, chest x-ray
      • Special studies as needed: arterial blood gas, carboxyhemoglobin, ECG, glucose
    • Physical therapy started immediately
  • 104. Drug Therapy
    • Analgesics and Sedatives
    • given for patient comfort
    • IV pain medications initially due to
      • GI function is slowed or impaired because of shock or paralytic ileus
      • IM injections will not be absorbed well
  • 105. Drug Therapy
    • Tetanus immunization- given routinely to all burn patients because of the likelihood of anaerobic burn-wound contamination
    • Antimicrobial agents- usually topical due to little or no blood supply to the burn eschar so little delivery of the antibiotic to wound
    • Drug of choice is: Silver sulfadiazine
  • 106. Nutritional Therapy
    • Fluid replacement takes priority over nutritional needs in the initial emergent phase
    • NG tube is inserted and connected to low intermittent suction for decompression
    • When bowel sounds return (48-72 hrs) after injury, start with clear liquids and progress up to a diet high in proteins and calories
  • 107.
    • Burn patients need more calories & failure to provide will lead to delayed wound healing and malnutrition
    • Give calorie containing liquids instead of water due to need for calories and potential for water intoxication
    • Enteral feedings into the duodenum (recommended) can: reduce nausea /vomiting, provide more continuous feedings, and increase wound healing
    Nutritional Therapy
  • 108. Calorie Intake Formula
    • (25 x wgt in kg) + (40 x TBSA burn)
    • Example for 50 kg patient with 50% TBSA burn:
    • (25 x 50) + (40 x 50) = 1250 + 2000 = 3250 Kcals
  • 109. Acute Phase
    • Begins with mobilization of extracellular fluid and subsequent diuresis
    • Is concluded when the burned area is completely covered or when wounds are healed. May take weeks or months
    • Patient is no longer grossly edematous due to fluid mobilization, full & partial thickness burns more evident, bowel sounds return, pt more aware of pain and condition
  • 110.
    • Healing begins when WBCs have surrounded the burn and phagocytosis begins, necrotic tissue begins to slough, fibroblasts lay down matrices of collagen precursors to form granulation tissue
    • Partial-thickness burns (if kept free from infections) will heal from edges and from below. (10-14 days)
    • Full-thickness burns must be covered by skin grafts
  • 111. Laboratory Values
    • Sodium- Hyponatremia can occur due to: silver nitrate topical oints as a result of sodium loss through eshcar, hydrotherapy, excessive GI drainage, diarrhea, excessive water intake
      • S/S of hyponatremia: weakness, dizziness, muscle cramps, fatigue, HA, tachycardia, & confusion
    • Hypernatremia can occur: too much hypertonic fluids, improper tube feedings, inappropriate fluid administration
      • S/S of hypernatremia: thirst; dried furry tongue; lethargy; confusion; and possible seizures
  • 112.
    • Potassium- hyperkalemia is note if pt is in renal failure, adrenocortical insufficiency, or massive deep muscle injury with lg. amts. of potassium released from damaged cells. Cardiac arrhythmias and ventricular failure can occur if K+ level greater >7mEq/L. muscle weakness & EKG changes are noted.
      • Hypokalemia is noted with silver nitrate therapy and long hydrotherapy. Other causes: vomiting, diarrhea, prolonged GI suction, prolonged IV therapy without K+ supplementation. Constant K+ losses occur through the burn wound.
  • 113. Complications of Acute Phase
    • Infection- due to destruction of body’s 1st line of defense. Partial thickness wds can convert to full-thickness wds with infection present. Pt may get sepsis from wound infections. Signs of sepsis are: high temp., increased pulse & resp., decreased BP, and decreased urinary output, mild confusion, chills, malaise, and loss of appetite. WBC bet. 10,000 and 20,000. Infections usually gram neg. bacteria (pseudomonas, proteus)
    • Obtain cultures from all possible sources:
    • IV, Foley, wound, oropharynx, and sputum
  • 114.
    • Cardiovascular- same as in emergent phase
    • Neurologic- possible from electrical injuries
    • Musculoskeletal- has the most potential for complications during acute phase due to healing and scar formation making skin less supple and pliant. ROM limited, contractures can occur
    • Gastrointestinal- adynamic ileus results from sepsis, diarrhea or constipation (due to narcotics & decreased mobility), gastric ulcers due to stress, occult blood in stools possible
    • Endocrine -stress diabetes mellitis might occur-assess glucose prn
  • 115. Nursing management-Acute Phase
    • Predominant therapeutic interventions are:
    • Fluid replacement continues from emergent phase to acute phases-- given for: fluid losses, administer medications, & for transfusions
    • Physical therapy- to maintain optimal joint function
    • Pain management- most critical functions as a nurse.
    • Nutritional therapy- provide adequate proteins & calories
  • 116.
    • Wound Care- the goals are cleanse and debride the area of necrotic tissue &debris, minimize further damage to viable skin, promote patient comfort, & reepithelialization or success with skin grafting.
    • Care for donor site and other grafts necessary
    • Excision and grafting- eschar removed to subcutaneous tissue or fascia, graft applied to tissue
      • Cultured epithelial autograft (CEA)uses patient’s own cells to grow skin-permanent
      • Artificial skin -examples: Alloderm, Life-Skin, etc.
  • 117. Rehabilitation Phase
    • Defined as beginning when the patient’s burn wound is covered with skin or healed and patient is capable of assuming some self-care activity.
    • Can occur as early as 2 weeks to as long as 2-3 months after the burn injury throughout the patient’s lifespan
    • Goals for this time is to assist patient in resuming functional role in society & accomplish functional and cosmetic reconstruction
  • 118. Clinical Manifestations
    • Burn wound either heals by primary intention or by grafting
    • Scars & Contractures may form
    • Mature healing is reached in 6 months to 2 years
    • Avoid direct sunlight for 1 year on burn
    • New skin sensitive to trauma
  • 119. Complications
    • Most common complications of burn injury are skin and joint contractures and hypertrophic scarring
    • Because of pain, patients will assume flexed position. It predisposes wounds to contracture formation
    • Use of physical therapy, pressure garments, splints, etc. are used to prevent/treat these
  • 120. Example of Contracture
  • 121. Example of a pressure garment
  • 122. Nursing management during Rehabilitation Phase
    • Must be directed to returning patient to society, address emotional concerns, spiritual and cultural needs, self-esteem, teaching of wound care management, nutrition, role of exercises and physical therapy explained. A common emotional response seen is regression.
  • 123. Special Needs of the Patient Care Staff
    • Critical Stress Defusing/Debriefing sessions should be offered early and often
    • Staff of burn units are prone to higher rates of burn-out. The care of a burn patient can be a long period that stresses the patient, care giver, and significant others. The road to recovery is full of potential threats to the patient. Support services are necessary for the medical team of any long-term burn patients.
