  • ObjectivesSafe and Effective are Environment Apply principles of asepsis to protect burn patients and open wounds.Manage the patients environment to prevent infection from auto contamination and cross contamination in patients with burn injuries.

  • Objectives ContinuedHealth Promotion and MaintenanceTeach everyone fire prevention strategiesInstruct everyone on the correct use of placement of smoke detectors and carbon monoxide detectors.

  • Objectives ContinuedPsychosocial IntegritySupport the patient and family in coping with permanent changes in appearance and functionEncourage the burn patient with wound and scars to participate in burn care.Assess the patients and familys use of coping strategies related to burn injury, treatment, possible changes and outcomes.Allow patients who have lost family members, homes or jobs time to grieve for their losses.

  • Objectives ContinuedPsychosocial IntegrityIdentify burn patients at risk for inhalation injury.Compare the manifestations of superficial, partial-thickness, and full-thickness burn injuries.Explain the expected manifestations of neural and hormonal compensation during the resuscitation/emergent phase of burn injury.Prioritize nursing care for the patient during the resuscitation/emergent phase of burn injury.

  • Objectives ContinuedUse laboratory data and clinical manifestations to determine the effectiveness of fluid resuscitation/emergent phase of burn injury.Prioritize nursing care for the patient during the acute phase of burn injury.Coordinate with the nutritionist to meet the nutritional needs for the patient during the acute phase of the burn injury. Evaluate the patients wound healing during the acute phase of the burn injury.

  • Objectives ContinuedCompare pain management for patients in the resuscitation/emergent and acute phases of burn injury.Describe the characteristics of infected burn wounds.Use appropriate positioning and range-of-motion interventions for prevention of mobility problems in the patient with burnsCoordinate nursing care for the patient during the rehabilitation phase of burn injury.

  • ClassificationsSuperficial Partial ThicknessDeep Partial ThicknessFull Thickness

  • Visualizing Burn Depth

  • Superficial Partial ThicknessOf all burn types; this type has the least damage because the epidermis is the only part of the skin that is injured.Symptoms: redness with mild edema, pain and increased sensitivity to heat. Blisters. Desquamation (peeling of dead skin) occurs for 2 to 3 days after the burn. The area heals rapidly in 3-5days without a scar or other complication.

  • Deep Partial ThicknessWounds extend deeper into the skin dermis, and fewer healthy cells remain. In these patients, blisters usually do not form because the dead tissue layer is so thick and sticks to the underlying dermis that it does not readily lift off the surface. Heals in 3-6wks, but scar formation results.Symptoms: the wound surface is red and dry with white areas in deeper parts. It may blanch slowly or not at all, edema is moderate and pain is less than superficial burns.

  • Full ThicknessWounds occur with destruction of the entire epidermis and dermis, leaving no true skin to heal on its own. Will require grafting. Take weeks to months to heal.Symptoms: has a hard, dry leathery eschar that forms from coagulated particles of destroyed dermis. Eschar must slough off or be removed before healing can occur.

  • Deep Full Thickness BurnExtend beyond the skin into underlying fascia and tissues. These injuries damage muscle, bone, tendons and leave them exposed. Symptoms: the wound is blackened and depressed, and sensation is completely absent. These wounds need excision and grafting. Amputation may be needed when an extremity is involved.

  • Changes From Burn InjuryChanges include:CardiacPulmonary GI (Curlings ulcer)Metabolic Immunologic

  • Vascular Changes Resulting From Burn InjuryFluid shiftthird spacing or capillary leak syndrome, usually occurs in the first 12 hr and can continue 24 to 36 hrProfound imbalance of fluid, electrolyte, and acid-base, hyperkalemia and hyponatremia levels, and hemoconcentrationFluid remobilization after 24 hr, diuretic stage begins 48 to 72 hr after injury, hyponatremia and hypokalemia

  • Cardiac ChangesHeart rate increasesCardiac output decreases

  • Pulmonary ChangesRespiratory failureInhalation injurySloughingPulmonary insufficiency and infection

  • Gastrointestinal ChangesDecreased blood flowMucosa is impairedPeristalsis is affectedCurlings ulcer

  • Metabolic ChangesIncreases metabolismCaloric needs double or triple depending on the extend of injury.Increased core body temperature

  • Immunologic ChangesProtective barrier destroyedInflammatory response activatedSuppressed immune function

  • Compensatory Responses to Burn InjuryInflammatory compensation can trigger healing.Sympathetic nervous system compensation occurs when any physical or psychological stressors are present.

  • Etiology of a burn InjuryDry heatMoist heatContact burnsChemical injuryElectrical injuryRadiation injury

  • Resuscitation/Emergent PhaseIs the first phase of a burn injury. The primary goals for this period are to:secure the airwaysupport circulation by fluid replacementkeep the patient comfortable with analgesicsprevent infection through careful wound caremaintain body temperatureprovide emotional support

  • Respiratory ManifestationsDirect airway injuryCarbon monoxide poisoningThermal injurySmoke poisoningPulmonary fluid overloadExternal factors

  • Cardiovascular AssessmentHypovolemic shock is a common cause of death in the emergent phase in patients with serious injuries.Monitor vital signs.Monitor cardiac status, especially in cases of electrical burn injuries.

  • Renal/Urinary AssessmentChanges are related to cellular debris and decreased renal blood flow.Myoglobin is released from damaged muscle and circulates to the kidney.Assess renal function, blood urea nitrogen, serum creatinine, and serum sodium levels.Examine urine for color, odor, and presence of particles or foam.

  • Skin AssessmentDetermine size and depth of injury.Determine percentage of total body surface area affected. Use "rule of nines," using multiples of 9% of total body surface area.

  • Surgical ManagementEscharotomyFasciotomy

  • Acute Phase of Burn InjuryBegins about 36 to 48 hr after injury and lasts until wound closure is completedCare directed toward continued assessment and maintenance of the cardiovascular and respiratory systems, as well as toward GI and nutritional status, burn wound care, pain control, and psychosocial interventions Begins about 36 to 48 hr after injury and lasts until wound closure is completedCare directed toward continued assessment and maintenance of the cardiovascular and respiratory systems, as well as toward GI and nutritional status, burn wound care, pain control, and psychosocial interventions

  • Dressing the Burn WoundStandard wound dressings Biologic dressings:Homografthuman skinHeterograftskin from other speciesAmniotic membraneCultured skinArtificial skinBiosynthetic dressingsSynthetic dressings

  • Surgical ManagementSurgical excision Wound covering:Skin graft

  • Nonsurgical ManagementDrug therapyIsolation therapyEnvironmental management

  • Rehabilitative PhaseRehabilitation begins with wound closure and ends when the patient returns to the highest possible level of functioning.Emphasis during this phase is on psychosocial adjustment, prevention of scars and contractures, and resumption of preburn activity.This phase may last years or even a lifetime if patient needs to adjust to permanent limitations.

    *Heart rate increases and cardiac output decreases because of the initial fluid shifts and hypovolemia that occur after a burn injury

    Cardiac output may remain low until 18-36hrs after the burn injury.

    Proper fluid resuscitation and support oxygen prevent further complications.*Direct injury to the lung from contact with flames rarely occurs. Rather, respiratory problems are caused by super heated air, steam, toxic fumes, or smoke.

    Such problems are a major cause of death in patients with burns and most likely occur when the burn takes place indoors. The upper airway is affected when inhaled smoke or irritants cause edema and obstruct the trachea. This often causes a reflex closure of the vocal cords.

    The ciliated membranes lining the trachea normally trap bacteria and foreign materials. Smoke and combustion products slow this activity, allowing these foreign particles to enter the bronchi.

    The lining of the trachea and bronchi may slough 48-72hrs after injury, enter the airway, narrow the trachea lumen, and obstruct lower airways.

    Leaking capillaries cause alveolar edema that can occur immediately or as late as one week after injury.********Safe environment (p541):Isolation therapy: Is used in some burn centers with the belief that it prevents cross contamination. All isolation methods use proper and consistent hand washing as the most effective technique for preventing infection transmission.Use of Asepsis: requires all health care personnel to wear gloves during all contact with open wounds. The use of sterile vs. clean gloves for routine wound care varies by agency. Change gloves when handling wounds on different areas of the body and between old and new dressings.
