Study Notes

Pathophysiology and Management of Burn Injuries

  • Burn injuries are categorized into three degrees, with temperatures above 44°C causing protein breakdown and resulting in cell and tissue damage.
  • Effects of burns include disruption of skin sensation, water loss prevention, and body temperature control.
  • Burns over 30% of the body surface area trigger an inflammatory response, leading to fluid leakage, tissue edema, blood volume loss, and increased levels of catecholamines and cortisol.
  • Different degrees of burns have varying appearances, sensations, healing times, and prognoses, with fourth-degree burns extending into underlying fat, muscle, and bone.
  • Burns are diagnosed based on depth, mechanism, extent, and associated injuries, and the size is assessed using methods such as the Wallace rule of nines and Lund and Browder chart.
  • Burn severity is classified based on total body surface area (TBSA) affected, involvement of specific anatomical zones, age, and associated injuries.
  • Prevention programs have decreased serious burn rates through education, regulations, and code of practice, including measures like setting water heaters below 48.8°C and limiting firework sales to children.
  • First aid management includes DRABC + 3B + 3C, stopping burning, maintaining breathing, examining the body, cooling and covering the burn, and general management such as O2 therapy, care of the burn wound, and nutrition for major burns patients.
  • Hyperbaric oxygenation and IV fluids are used for extensive burns prone to infection, with specific fluid resuscitation and monitoring requirements for children and adults based on TBSA.
  • The Parkland formula determines the volume of IV fluids required over the first 24 hours, with additional maintenance fluid for children.
  • Burn injuries are prone to developing contractures and causing loss of function, affecting an individual’s activities of daily living (ADL).
  • The American Burn Association classifies burn severity as minor, moderate, or major based on TBSA affected, age, high voltage injury, inhalation injury, circumferential burn, and significant burn to specific body parts.

Pressure Therapy Effectiveness and Scar Management in Burn Patients

  • 70 burn cases with over 1 year since injury were surveyed to measure the subjective rating of pressure therapy effectiveness and its impact on daily life
  • The survey used an ordinal scale from 1 to 6 with 11 items addressing treatment effectiveness, life changes, and satisfaction
  • Non-parametric tests, Wilcoxon Sign Rank Test, and Cluster analysis were used for data analysis, identifying major determinants and correlating with demographic data
  • The study suggests turning pressure garments into 'pleasure garments', expanding services for individual needs, developing work rehabilitation, and providing support for patients with low educational levels
  • Eschar is dead tissue that sloughs off from the skin, often seen in burn injuries, and may require surgical removal to prevent infection
  • Active scars may be red, firm, thick, or raised, and their appearance depends on multiple factors including wound care and location
  • Types of scars include cicatrix, hypertrophic, keloid, and contracture, each with distinct characteristics and potential complications
  • Keloid scars result from overgrowth of granulation tissue and can cause severe itchiness, pain, and changes in texture, more common in people of sub-Saharan African descent
  • Scar formation involves collagen remodeling, capillary regression, and increasing tensile strength, lasting from 21 days to two years in full-thickness wounds
  • Wound care directly impacts scar formation, with adequate care minimizing scarring
  • Eschar may require surgical removal to prevent infection, especially in immunocompromised patients, and circulation to affected limbs should be assessed
  • Scar management is part of the last phase of wound healing, involving collagen cross-linking and replacement of disorganized collagen by organized collagen, resulting in restoration of normal dermal composition and tensile strength
