  1. Timby/Smith: Introductory Medical-Surgical Nursing, 10/e 01/25 PG 1054 Chapter 66: Caring for Clients with Burns By: P.K. Williams, RN

  2. 05 Objectives: 02/25 Pg 1053 On completion of this chapter, you will be able to: 1. Explain how the depth and percentage of burns are determined. 2. Name three life-threatening complications of serious burns. 3. Differentiate between open and closed methods of wound care for burns. 4. Name three sources of skin grafts. 5. Describe nursing management for the client with a burn injury.

  3. 15 Words to Know 03/25 Pg 1053 • Allograft Autograft Closed method • Debridement Epithelialization Eschar • Escharotomy Heterograft Open method • Full-thickness-graft Hyperbaric oxygen treatment • Slit graft Split-thickness-graft • Stridor Tachypnea

  4. Burn Injuries***04/25 Pg 1053 • Pathophysiology, Etiology: Heat; Chemicals; Electricity • Heat:Cell damage; Protein coagulation • Severity: Temperature of heat source; Durationof contact; Thickness of tissue exposed; Burn location • Chemicals:Liquefy tissue; Loosen cell attachment*** • Electrical: Cardiac dysrhythmias; Central nervous system complications***

  5. Question 05/25 Pg 1053 Is the following statement true or false? A burn’s severity is affected by the temperature of the heat source.

  6. Answer 06/25 Pg 1053 True. A burn’s severity is affected by the temperature of the heat source. Additional factors, which affect a burn’s severity include duration of contact, thickness of tissue exposed to the heat, and the location of the burn.

  7. Burn Injuries*** 07/25 Pg 1053 • Pathophysiology • Effect of inflammatory process • Neuroendocrine changes; Edema • Fluid, electrolyte status alteration • Anemia; Hemoconcentration • Factors affecting mortality

  8. Depth of Burn Injury***08/25 Pg 1053 • Color • Skin Characteristics • Sensation in Burn Area • Classification Superficial 1stDrg Partial thickness 2ndDrg Full thickness 3rd Dr Through adipose tissue 4rth Drg

  9. Depth of Burn Injury 04/25 Pg 1053 Figure 66-2 Left: Deep partial-thickness burn Right: Superficial partial-thickness burn

  10. Question 10/25 Pg 1053 Is the following statement true or false? Burns can affect fluid balance.

  11. Answer 11/25 Pg 1053 True. As a response to the trauma of a burn, fluid shifts, which results in edema. Not only does it result in edema, the fluid is trapped and unavailable to the rest of the body. Decreased blood pressure (due to decreased fluid volume) can result in irreversible shock.

  12. Zones of Burn Injury 12/25 Pg 1054 • Zone of Coagulation • Zone of Stasis • Zone of Hyperemia

  13. Burn Injury Extent • Rule of Nines*** • Percentage of TBSA Burned • Client’s Palm: 1% of TBSA 13/25 Pg 1056

  14. Burn Injuries 14/25 Pg 1053 • Assessment Findings: Signs and Symptoms • Light pink to black skin color; Edema; Blistering; Pain; Compromised breathing; Symptoms of hypovolemic shock; Entrance, exit wounds • Diagnostic Findings: Physical inspection; Radiographs • Medical Management: Potential life-threatening complications: Inhalation injury; Hypovolemic shock; Infection • Major burns: Transport to regional burn center

  15. Question 15/25 Pg 1056 Is the following statement true or false? An infection within a burn wound can be life-threatening.

  16. Answer 16/25 Pg 1056 True. An infection within a burn wound can be life-threatening. Outcome of a burn injury depends on the initial first aid and subsequent acute treatment. Three complications of burns can be life-threatening: inhalation injury, hypovolemic shock, and infection.

  17. Burn Injury Medical Management17/25 Pg 1056 • Initial First Aid: First priority: Prevent further injury; Observe for respiratory difficulty • Acute Care: Assess extent of burn injury, additional trauma • Interventions: Ventilation; Fluid resuscitation • Endotracheal tube; Bronchoscopy • Mechanical ventilation; Tracheostomy; Hyperbaric oxygen treatment • IV analgesics; Tetanus immunization

  18. Burn Injury Wound Management 18/25 Pg 1058 • Infection prevention measures; Debris Removal • Open Method: Exposes burned areas to air;*** Used only for areas where it is difficult to apply dressings (face, perineum) • Isolation; Sterile environment; Escharotomy • Closed Method: Current, preferred method*** • Use of dressings: Nonadherent; Absorbent; Occlusive, semiocclusive; Dressing changes • Antimicrobial Therapy: Silver sulfadiazine; Mafenide; Silver nitrate; Acticoat

  19. Burn Injury Surgical Management19/25 Pg 1059 • Surgical Management: Debridement • Removal of necrotic tissue • Four ways: Naturally; Mechanically; Enzymes; Surgery • Disadvantage: Bleeding • Covering of healthy tissue: Skin graft; Temporary skin substitute; Cultured skin

  20. Surgical Management: Skin Grafting20/25 Pg 1053 • Purpose: Lessen infection; Minimize fluid loss; Hasten recovery; Reduce scarring; Prevent loss of function • Keratinocytes regenerate epidermis • Used for deep partial-thickness and full-thickness burns • Unassisted Healing: Granulation tissue; Contractures; Chronic open wounds

  21. Surgical Management: Skin Grafting 21/25 Pg 1059 • Sources for Skin Grafts • Autograft: Client’s own skin • Allograft: Human skin from cadaver • Heterograft: Animal skin • Types of Autografts • Split-thickness; Full-thickness; Slit • Disadvantages; Pressure garments; Sunscreen

  22. Surgical Management: Skin Grafting 22/25 Pg 1053 • Skin Substitutes • Cover wound; Promote healing • Direct interaction with body tissues • Applied soon after skin is healed and débrided • Cultured Skin • Culture client’s skin; Collagen • Disadvantage: Pigmentation mismatch

  23. Burn Injury Wound Management23/25 Pg 1062 Figure 66-9 Biobrane dressing applied to lower extremity partial-thickness burn

  24. Burn Injury Nursing Management24/25 Pg 1053 • Assessment • Wound; Client’s status • Calculation and infusion—fluid replacement requirements • Treatment of shock; Pain relief • Wound care: Antimicrobials; Dressings; Monitoring for infection; Emotional support • Client teaching: Exercise; Pressure garments; Skin care measures
