Burns

  1. 1. BURNS MR. Prasanth.K MSc cardiothoracic nursing
  2. 2. ANATOMY OF SKIN
  3. 3. The Skin  Membrane that covers entire body  Largest, most dynamic organ  Epidermis  Dermis  Subcutaneous layer (superficial fascia)  Deep fascia
  4. 4. Definition  Injury to the tissues of the body caused by heat, chemicals, electric current, or radiation.
  5. 5. Incidence  Domestic cases – 93-95%  India – 0.4million / year  Women are more affected than men – 1.6:1  Overall mortality – 3.5/100000 popu
  6. 6. Burn wound healing  Inflammation  Proliferation  Remodeling
  7. 7. Inflammation  Platelet adhesion  Fibrin deposit  Thrombus + vasoconstriction  Hemostasis  Local vasodilatation and increase of capillary permeability  Neutrophil (24 hrs)  Monocyte  Macrophages  Consume pathogens and dead tissue  Secrete various growth factors  Proliferation of fibroblasts + deposited of a provisional wound matrix
  8. 8. Proliferation (2-3 days post burn)  Number of fibroblasts at peak  Granulation  Reepithelialization
  9. 9. Remodeling (lasts for years)  Collagen fibers are reorganized  Scars contract and fade in color
  10. 10. When burn extends to dermal tissue scars developed are - hypertrophic- overgrowth of dermal tissue remains in the boundaries - Colloid – extends beyond boundaries
  11. 11. ETIOLOGY
  12. 12. TYPES
  13. 13. Thermal Caused by – flash , flame , scaled, contact with hot objects Management – extinguish flame Flush with cool water
  14. 14. Chemical Agent Forms Management Acid House hold cleaners HCL, oxalic, Water irrigation Irrigate skin with soup solution Remove the person or agent away. Take self precaution and remove the cloth which contain chemical. Alkali Drain cleaners Fertilizers Adhere to tissue and protein hydrolysis Irrigate skin with slightly acidic solutions like lemon water
  15. 15.  Dry chemical – Brush away from skin Irrigate skin
  16. 16. Smoke and inhalation injury Agent Injury signs and symptoms Management Carbon monoxide poisoning - Incomplete combustion of burning material Cherry red skin color 10-20% - head ach , dizziness , nausea, abdominal pain 21-41%- irritability , confusion , stupor, hypotension , bradycardia, pale to dark red skin color 41-60%- convulsion , coma, hypotension, tachycardia >60%- death 100% o2
  17. 17. Injury above glottis – Usually thermally produced Inhalation f hot air , steam , or smoke Especially .- burn in enclosed space Mucosal burning of larynx and oropharynx Redness Blistering Edema Quick mechanical obstruction Singed nasal hair Hoarseness painful swallowing Darkened oral and nasal membrane Carbonaceous sputum Medical emergency
  18. 18. Injury below glottis – Chemically produced Pulmonary edema ARDS Close observation for ARDS
  19. 19. Electrical burns  Damage to the nerves and vessels  Factors related to severity voltage Tissue resistance Current pathways Surface area of contact Length of time
  20. 20. S/S Ice berg effect Chance of cervical spine injury (fall) Muscle contraction – fracture Dyarrhythmias- AF, VF Cardiac arrest Metabolic acidosis Myoglobinuria lead to – acute renal tubular necrosis

  23. 23. Radiation  Source – solar, X ray , radioactive agent  Management Shield Move client away
  24. 24. PATHOPHYSIOLOGY
  25. 25. AMERICAN BURN ASSOCIATION - burn unit referral criteria  Burn injuries that should be referred to a burn unit include the following 1. Partial thickness burns more than 10% TBSA 2. Burns that involve s the face hands feet genitalia perineum or major joints 3. Third degree burns in any age group 4. Electrical burns including lightning injury 5. Chemical burns 6. Inhalation injury 7. Burn injury in patients with preexisting medical disorders that could complicate management, prolong recovery, or affect mortality 8. Any patients with burns and concomitant trauma (fractures) in which the burn injury poses the greatest risk of morbidity or mortality. 9. Patients who will require special social, emotional, or long term rehabilitation intervention
  26. 26. CLASSIFICATION OF BURN INJURY  Severity determined by – Depth of burn Extent of burn – calculated by TBSA Location of burn Patient risk factors
  27. 27. Classification based on depth  Superficial  Partial thickness superficial partial thickness deep partial thickness  Full thickness
  28. 28. Superficial burns  Involves epidermis  ---- UV rays, sun burn, minor flash injury, mild radiation  s/s Skin color – pink – bright red Slight edema Chills, nausea, vomiting – in extensive burns Management – I/V fluid treatment
  29. 29. Partial thickness Superficial partial thickness Deep partial thickness Affected - Dermis and papillae of dermis Bright red color + moist + glistening appearance + blisters + blanching on pressure + pain response to temperature and air is severe Heal with in 21 days + minimal or no scaring Management – analgesics Skin substitutes for large disrupted blisters Dermis +more deeper Pale + waxy+ moist / dry large blisters + decreased capillary refill + less painful Heal – more than 21 days Complication Necrosis may lead to full thickness injury , contractures Management – excision and grafting
  30. 30. Full thickness burn  Epidermis + dermis + epidermal appendages + subcutaneous fat+ connective tissue + muscle + bone  Pale ,waxy ,brown ,mottled ,leathery ,firm to touch  No sensation of pain Management – Skin grafting
  31. 31. Classification by extent of burn  Lund- Browder chart  According to Rule of nine ( not accurate for estimating the percentage TBSA for adults who are short, obese or very thin. )  Sage burn diagram – computerized burn estimation tool. (www.sagediagram.com)

  65. 65.  Impaired skin integrity related to thermal injury as manifested by blisters and lesions.  Activity intolerance related to weakness, as manifested by verbalization.
  66. 66.  Anxiety related to prognosis of disease condition and disturbed body image.  Risk for infection related to impaired skin integrity and suppressed immune response  Risk for contractures related to the burn injury
  67. 67.  Ineffective individual coping related to fear and emotional impact of burn injury as evidenced by increased questioning  Imbalanced nutrition less than body requirement related to inability to intake as evidenced by weight loss.  Hyperthermia, related to infection, as manifested by rise in body temperature..
  68. 68. Research studies
  69. 69.  The treatment of pain produced during the management of burn injury has been an ongoing problem for physicians caring for these patients. The main therapeutic option for analgesia has been the repeated and prolonged use of opioids.
  70. 70.  The adverse effects of opioids are well known but the long term use of opioids which produces tolerance with accompanying dose escalation and dependence is most problematic. Another potentially important consequence of opioid exposure that sometimes masks as tolerance is that of opioid induced hyperalgesia.
  71. 71.  This syndrome is manifest as enhanced pain, sensitivity and loss of analgesic efficacy in patients treated with opioids who actually become sensitized to painful stimuli. This article focuses on the treatment of burn pain and how current analgesic therapies with opioids may cause hyperalgesia and affect the adequacy of treatment for burn pain. This article also provides possible modalities to help therapeutically manage these patients and considers future analgesic strategies which may help to improve pain management in this complicated patient population.
