BURNS MANAGEMENT - ACUTE (1).pptx

1) Burns are classified based on depth and cause, with thermal burns being the most common. Depth ranges from superficial to full thickness burns. 2) Initial management focuses on airway, breathing, circulation, and fluid resuscitation to prevent shock. Wound care aims to prevent infection using antimicrobial dressings. 3) Later stages involve wound debridement and skin grafting to promote healing, along with managing pain and nutrition. Early excision within 5 days of injury reduces risk of sepsis.

MANAGEMENT OF PA TIENT WITH BURNS
Definition Burn injury is a syndrome of Local and Systemic manifestations of exposure to • High temperature, • Electrical energy, • Chemicals • Radiation
CLASSIFICATION • Thermal • Flame burns – 50% • Scalds from hot liquids, e.g. boiling water, cooking oil – 40% • Contact burn, e.g. stoves, heaters, irons, • Non thermal • Electrical burn • Chemical Burns • Friction burn • Radiation burn
Depth of burn • Superficial • Superficial partial thickness (dermal) • Deep partial thickness (dermal) • Full thickness • 1st degree • 2nd degree • A • B • 3rd degree • 4th degree
Superficial/ 1st degree • Sunburn • Low-intensity flash • Epidermis involvement • Redness • No blisters • Tingling, Pain that is soothed by cooling
Superficial partial thickness (dermal) • epidermis and papillary dermis • Painful, red, blistered, moist, soft, and blanching when touched. • When blistered are deroofed, the skin is moist, red, and hypersensitive.
Deep Partial-Thickness (Second Degree) • Epidermis, upper dermis, portion of deeper dermis • Blisters that are red, shiny. • Severe pain caused by nerve injury • edema
Full-Thickness (Third Degree) • Epidermis, entire dermis, and subcutaneous tissue • Dry; pale white, Leathery skin • visible thrombosed blood vessels • Pain free • surgical intervention required
4th Degree • Involves muscles tendons and bones
Extent of Body Surface Area Injured • Wallace’s Rule Of Nines, • Lund And Browder Method, • Palm Method.

MANAGEMENT
BURNS PAIN 1. Procedural pain and associated pain anxiety 2. Background pain 3. Breakthrough pain
ASSESSMENT • Surface area • Depth • Inhalational component • Severity • Additional • Oedema • Pain • Hand • Mobility
INHALATIONAL BURNS • Physical signs to observe: • Hoarse vocal quality • Stridor • Singed facial / nasal hair • Soot stained sputum • Erythema (Superficial reddening of the skin, usually in patches, as a result of injury or irritation causing dilatation of the blood capillaries) • Oedema of face • Inspiratory and end expiratory crackles on auscultation • Chest x-ray changes
SEVERITY OF BURNS • Factors to Consider • Type • Depth • Body Surface area burned • Age: Adult vs Paediatric • Pre-existing medical conditions • Associated Trauma • blast injury • fall injury • Airway compromise • Child abuse
• Mild • Paediatric <10% • 10 yrs < 20% BSA • 20 yrs < 20% BSA • 30 yrs< 15% BSA • Moderate • Pediatric 10-20% • 20 yrs 20-30% BSA • 30 yrs 15-20% BSA • Excluding hands, face, feet, or genitalia • Without complicating factors
• Severe burns • Pediatric >10% BSA • 20yrs > 30% BSA • 30yrs > 20% BSA • Burns with respiratory injury • Hands, face, feet, or genitalia • Burns complicated by other trauma • Electrical and deep chemical burns • Underlying health problems HOSPITALISATION IN ALL SEVERE AND MOST MODERATE BURNS
PRE HOSPITAL MANAGEMENT • Rescuer to avoid injuring himself • Remove patient from source of injury • Stop burn process • Burning clothing; jewelry, watches, belts to be removed • Pour ample water on burnt area (not ice/ ice packs – skin injury & hypothermia) • Chemical burns: • Remove saturated clothing • Brush skin if agent is powder • Irrigation with copious amount water to be started and continued in hospital • Electrical burns: • Turn off the current • Use non-conductor item to separate from source
• Small thermal burns (<10% TBSA ) may be covered with a clean, tap water-damped towel for patient comfort and protection until definite medical care instituted. • Cooling of injured area within 1 minute helps minimize the depth of injury. • If the burn injury is large (>10% TBSA) it is not advisable to immerse the body part in cool water since doing so might lead to extensive heat loss. • Do not break blisters. • Do not apply lotions, powders, grease, ghee, gentian violet, calamine lotion, toothpastes, butter and other sticky agents over the burn wound. • Prevent contamination: Wrap burn part in clean dry sheet /cloth. • Assess for life threatening injuries.
EMERGENT/RESUSCITATIVE PHASE • This phase may last 24-48 hours after injury • This phase characterized by • Life-threatening airway problems • Cardiopulmonary instability • Hypovolemia • Goal Maintain vital organ function and perfusion • Physical examination • Assess A B C • AIRWAY • BREATHING • CIRCULATION • INVESTIGATIONS • Labs: CBC, electrolytes, BUN • Pulmonary assessment: ABG, CXR, carboxyhemoglobin
• AIRWAY & BREATHING • Overt signs and symptoms of airway obstruction- Progressive hoarseness • Suspected inhalational injury (smoke/ carbon monoxide intoxication) • Unconscious patient/ rapidly deteriorating patient • Acute respiratory distress • Burns of face & neck • Extensive Burns (> 40% TBSA) ET intubation + assisted ventilation with 100% O2
FLUID RESUCITATION • Parkland Formula • Evan’s formula • Brooke formula
Parkland Formula • Fluid of Choice • Lactated Ringer’s (RL) • NS can produce hyperchloremic acidosis 4 ml x % of burn x weight (Kg) in 24 hours • FIRST 24 HOURS • First ½ of total volume given in the first 8 hours • Remaining ½ of total volume given over following 16 hours • NEXT 24 HRS • Total volume ½ of first day • Colloids ( 0.5 ml / kg / % ) • 5 % glucose to make up the rest
Assessment of Adequacy Monitor • Urinary Output • Adult: > 1 ml/ kg/ hr • Children > 0.5ml/kg/hr • Daily Weight • Vital Signs • Heart rate and blood pressure • CVP • Level of Consciousness • Laboratory values
GOALS • Prevention of infection and Wound care • Excision and grafting • Pain management • Nutritional therapy • Physical, psychosocial and occupational therapy
Wound care • Wound care should be delayed until a patent airway, adequate circulation and adequate fluid replacement have been established.
Microbiology • Frequent monitoring for bacterial infection • Wound swabs • biopsies • Early cultures positive/ high counts • Increasing colony counts • Virulent / resistant organisms in culture • Impending invasive wound infection. • Wound colony counts • High risk of graft failure.
Hydrotherapy •Shower, bed baths or clear water spray •Maintain appropriate water and room temperature Limit duration to 20-30 minutes •Don’t burst blisters, aspirate them !!! Trim hair around wound •Dry with towel; don’t rub! •Clean unburned skin and hair
Wound care • Full thickness and deep dermal burns require antibacterial dressings to prevent infections prior to surgery. • Superficial burns require simple dressings as they heal completely within 3 weeks • Optimal dressings environment can make significant difference in healing. • 2 types of wound treatment used to control infection • open method • Closed multiple dressing change method
Antimicrobial Agent • Silver sulfadiazine 1% cream: • Most bactericidal agent • Minimal penetration of eschar • Mafenide acetate 5% to 10% (Sulfamylon) hydrophilic-based cream • Effective against gram-negative and gram-positive organisms • Diffuses rapidly through eschar • In 10% strength, it is the agent of choice for electrical burns because of its ability to penetrate thick eschar • Silver nitrate 0.5% aqueous solution- • Bacteriostatic and fungicidal • Does not penetrate eschar
• Bacitracin/ Neomycin/ Polymyxin B • Not broad spectrum, painless, easy to apply • Nystatin • Antifungal • Mupirocin • Anti staphylococcal • Betadine • Drying effect makes debridement of the eschar easier • Acticoat ( Antimicrobial occlusive dressing ) • A silver impregnated gauze - left in place for 5 days Apply sterile water every 3-4 hours
Soak silver dressings and gauze in WATER ( Not in saline ). Apply the silver dressing. Wrap with moist gauze.
Dressing in superficial burns • Non irritative anti microbial cleanser • Non adhesive barrier • Dry and absorbant dressing material • Collagen sheets
Apply Antibiotic Scrubbing
Dress the burn with petroleum gauze and dry gauze
Collagen sheet dressing • Acellular sterile collagen sheet • Applied 1st & 2nd degree burns • Needs to be applied early • No need for repeated dressings • Reduces pain, secretions
• Special Considerations: • Wrap Joint area lightly to allow mobility Facial wounds may be left open Circumferential burns: wrap distal to proximal • All fingers and toes should be wrapped separately Splints over dressings
Debridement • May be completed at the bedside or as a surgical procedure. • Types of Debridement: • Natural • Body & bacterial enzymes dissolve eschar; takes a long time • Mechanical • Sharp (scissors), Wet-to-Dry Dressings or Enzymatic Agents • Surgical • Tangential Excision • Full thickness excision • Escharotomy • Escharectomy
EarlyExcision • Within the first 3-5days • After 5 days chances of Sepsis higher and bleeding more • 15% of BSA is excised at a time • Spaced apart (every 2 or 3 days) • By one estimate excision of 1% burn area can result in 100 ccs blood loss • The goal of early excision is to remove all de- vitalized tissue and prepare the wound for skin grafting
Order of Excision • Areas easy and quick to excise: trunk and legs • Joints and neck • Hands and face • Special Care • Neck • Eyelids • Lips • Ears • Hand & fingers • Perineum & Gentials
Tangential Excision • deep dermal burns & 3rd degree burns • Repeated removing of very thin slices (0.5 mm thick) of burned tissue from the zones of stasis and coagulation. • to achieve surface with viable bleeding, which are suitable for grafting
Fascial Excision • Removes all layers of eschar and underlying tissue to the level of fascia. • minimizes bleeding • provides a reliable, clean, vascular bed. • Recommended • -deeper burns • Hight TBSA • High risk pt
Eschartomy • An escharotomy is a surgical procedure used to treat full thickness (third-degree) circumferential burns. • Full-thickness circumferential burn of an extremity or Trunk can result in vascular/ respiratory compromise.
Indications • Indicated when the circulation is compromised due to increased pressure in the burned limb and can not be relieved by simple elevation. • Circumferential chest, abdomen & limbs • Pain on passive extension • Pallor • Paresthesia • Poikilothermia • Paresis • Pulselessness
Fasciotomy • the fascia is cut to relieve tension or pressure • loss of circulation to an area of tissue or muscle. • Esp limbs • Patients with Electrical Burns
Wound Closure • After excision the wound, there is wound closure. • Goals: • Reestablish barrier (epidermis) to prevent bacterial invasion and evaporative water loss • Reconstitute the dermis to provide durability, pliability and acceptable cosmetics. • If wounds are deep (full-thickness) or extensive, spontaneous re- epithelialization is not possible. Therefore, coverage of the burn wound is necessary by using patients own skin or other methods. • This is called as grafting
• few days to several months. • undergoing regular dressings. • Regular pain relief is essential • Inadequate pain relief in the early stages can result in a complete reluctance of the patient to participate in their rehabilitation in both the short and long term. • Early commencement of reconstruction and rehabilitation is the key • Staged introduction of multi modal rehab • REMEMBER TOMORROW MIGHT BE TOO LATE!
Classification of skin grafting • Full thickness skin graft (FTSG) • Partial thickness skin graft also called split thickness skin graft (SSG/ STSG) • Composite graft –skin along with underlying tissue is grafted
SSG • Skin graft including the epidermis and part of the dermis. • Thickness depends on the donor site and needs of the patient • Can expand upto 9 times • Frequently used as they can cover large areas and the rate of autorejection is low.
Indications • Immediate coverage of clean soft tissue defects • A larger availability • Minimal donor area issues • Donor areas can be reused • Prevention of scar contracture. Contraindications • Cannot be used in areas where good cosmesis or durability is essential • Significant wound contraction • Donor complications scarring
Full Thickness • epidermis and the entire thickness of the dermis • Indications • Full thickness loss • contraindications • Recipient bed cannot sustain the graft. • On avascular tissues • Uncontrolled bleeding in the recipient bed

Splinting & Positioning • Done to Prevent Contracture • After skin grafting to secure and stabilize graft • The positioning of the burn patient is vital in bringing about the best functional outcomes in rehabilitation • Begin immediately after the injury occurs • Positioning should be designed for the specific individual’s needs • Should not compromise mobility and function
Primary Splints • acute phase and pre grafting period • used to position the involved joints during sleep, inactivity, or periods of unresponsiveness. Postural Splints • Immediate post graft phase • Worn continuously for 5 to 14 days until the graft is secure. Types Of Splinting
Follow up Splints • Chronic phase of burn care begins with wound closure. • Dynamic splints (movable parts) are used to increase function. • Provide slow steady force to stretch a skin contracture, or provide resistive force for exercise.
Splinting • Reduces edema • Maintains joint alignment • Maintains tissues elongated • Prevents contracture formation • Promotes wound healing • Relieves pressure • Protects joints, exposed tendons and new grafts/flaps
