Factors Associated with Burns Age (sunburn exposure, < sensation, dementia, elderly and children are more prone) Smoking carelessly Alcohol and drug intoxication Physical or mental disabilities Certain occupations Look for abuse (Cigarette burns)
4 Kinds of Burns Thermal Chemical injury Electrical injury Radiation injury
Burn Priority Neutralize Flush CPR Corticosteroids Increase fluids Cool water
Depth of Burn Injury Superficial-Thickness (pink-red, blanchable/chills/headache, N/V, skin peals) Partial thickness (red/blister, pale/waxy, large blisters) Full Thickness (no cells to repopulate, pale/waxy/yellow/brown/mottled/charred/non-blachable/hard/dry/leathery/edema
Measure % of Body with Rule of 9's: Anterior and Posterior Head/Neck = 9 Upper Limbs = 18 Trunk = 36 Perineum = 1 Lower Limbs = 36
Complications of Major Burns Integumentary Cardiovascular Respiratory GI Urinary Immune Metabolism
Emergent Phase of Burns First 48 hr: Fluid loss,Maintain body temperature Goals of management include: o Secure airway o Support circulation—fluid replacement o Prevent infection o Maintain body temperature o Provide emotional support
Injuries to Respiratory from Burns Direct airway injury (Fire burn) Carbon monoxide poisoning (more binding than O2, Takes over cells, Visual impairment, coma, death, odorless, colorless) Thermal injury (Smoke poisoning, Toxic gas) Cyanide poisoning (Headache, seizure)
Cardiovascular Issues from Burns Hypovolemic shock Monitor vital signs, cardiac status, heart monitor Restore fluid
Renal/Urinary Trauma from Burns Changes are related to cellular debris and decreased renal blood flow Myoglobin is released from damaged muscle and circulates to the kidney Assess (BUN, Creatinine, Serum sodium levels) Examine urine color, odor, and presence of particles or foam
Gastrointestinal Issues from Burns Changes in GI function are expected Assess for GI bleeding, Paralytic ileus
Emergent/Resuscitative Phase of Burn Onset of injury to Fluid restoration Estimate extent of injury First Aid Respiratory Management Fluids Monitor urine output Hemodynamic monitoring
Acute Phase of Burn Injury Diuresis to wound closure Wound management Nutritional therapies (Enteral or TPN) Control infection Pain management
Escharotomy Longitudinal incision to release taut skin and allow for expansion from edema
Surgical Debridement for Burn Fasciectomy (Full-thickness burns only, fat and lymphatic tissue loss) Mechanical Enzymatic
Auto-grafting I give to me
Biologic and biosynthetic dressings Homograft (Another human) Heterograft (Pig skin) DuoDerm dressing
Dressing the Burn Wound Open or closed Positioning, Splints and Exercise (Prevent contractures, Ambulate ASAP) Support Garments (reduce scaring, Jobst garment 6 mo – 1 yr)
Topical Antibiotics Sulfamylon (it burns) Silver Nitrate (blackens everything it comes in contact with, use only in first 72 hrs) Silvadene (silver sulfadiazine)(marked leukopenia, but corrects itself)
Other Meds Systemic antibiotics Tetanus H2 blockers or PPI
Rehabilitative Stage Wound closure till return of highest level of health Biopsychosocial Prevention of contractures Vocational, occupational, physical rehabilitation
