Objectives Upon completion of this lecture, participants will be able to: Identify the components of a primary and secondary burn survey Apply the Rule of Nines to make an initial estimate of burn content Distinguish between partial-thickness and full-thickness burns
Prevelance of Burns 1.25 million burn injuries require medical attention in the United States every year Burns can be mild or very severe, requiring hospitalization and possibly more than one surgery
The Skin The skin is the bodys outer covering. It protects us against heat, light injury, and infection It also regulates body temperature
Burns A burn is damaged tissue caused by heat, chemicals, electricity, sunlight or nucler radiation. Burns caused by scalds, building fires, flammable liquids and gases are most common
Burn Injuries First Degree Second Degree Third Degree Fourth Degree (ABA)
Partial Thickness Full Thickness
First Degree Burns Sunburns are the best example Involve only the superficial layer of the epidermis Tenderness, redness typical Will not make you very sick Heal on own Healing time: 4-5 days OTC pain management
First Degree Burn
Another First Degree Burn
Second Degree Burns Difficult to diagnose because they vary in nature May be superficial to very deep Very moist appearance Second degree burns blister immediately Most blisters should be removed Healing time: approximately 2 weeks OCT pain management
Picture of First and Second Degree Burns
Second Degree Burn
Second Degree Burn Variability Superficial second degree: Heal on own
Deep partial thickness: Treat like third degree burns Grafting required
Second Degree Burn Variability
Second Degree Pain Factor Epidermis has been lifted off by fluid Most painful because nerve endings are preserved Scarring is minimal if healing occurs within 2-3 weeks If the wound is open for a longer period of time, grafting is indicated
Deep Partial Thickness
Third Degree Burns Epidermis and dermis are destroyed Appear whitish, charred or translucent Dry, leathery Red, white, brown, grey Coagulated vessels are often seen Full thickness
Third Degree Burns continued Require grafting If third degree burns are not excised, they will not heal Exception: small third degree burns less than 5cm can heal from the outside edges in
Third Degree Burn
Third Degree Circumferential
Third Degree to Buttocks
Third Degree to Hand
Estimating Burn Injury Rule of Nines Divide the body up into sections which equal nine percent Each arm is nine Each leg is two nines (front/back) Chest is two nines (belly button & higher, front/back) Abdomen is two nines (belly button & lower, front/back) Head is nine And the perineum is.one Area of patients palm equals one
Rule of Nines
Whats a Lund and Browder? A tool that divides the body up into smaller areas Good for estimating burns in children Kids have relatively big heads and relatively small legs compared to adults this is why this tool was developed You cannot use the Rule of Nines for children! More accurate than Rule of Nines Total Body Surface Area (TBSA)

Two Points to Remember When Estimating Burn Injury Debride the blisters before you estimate the size First degree burns do not count!! For irregular burns, the palm of the hand is about 1% of TBSA
Burn Survival
Management of a Burn Victim at the Scene STOP STOP STOP STOP STOP STOP STOP STOP THE THE THE THE THE THE THE THE BURNING BURNING BURNING BURNING BURNING BURNING BURNING BURNING PROCESS PROCESS PROCESS PROCESS PROCESS PROCESS PROCESS PROCESS
How to Stop the Burning Process Flame burns: smother the fire with water or a blanket; make sure fire is out and remove burned clothing Scald injuries: cool the area (DO NOT APPLY ICE!), then keep dry and covered Chemical injuries: flush with water, and lots of it!
Tar, Asphalt and Plastic Injuries Cool the offending element Leave it in place! Transport patient to nearest emergency facility
Tar Injury
Electrical Injuries If you are at the scene, make sure the person is not in contact with the electrical current Most people killed by electrical injuries do not die from their burn injuries they die from cardiac dysrhythmias Ventricular fibrillation is usually the culprit
Electrical Injuries continued Current density is maximum at entry and exit points (most condensed) Current enters the body through a small opening, then travels deep through the body and exits through a small opening This is why electrical burns may be deceiving damage is hidden!!!
Electrical Injury
Electrical Injury after Debridement
Typical Exit Wound
Electrical Shock Summary May result in unconsciousness, convulsions, loss of memory Orthopedic injuries common Spine fractures may result from tetanic contractions of muscles induced by high voltage current
Airway Burns Inhalation of smoke, steam, superheated air or toxic fumes Swelling can cause decrease flow of air
Initial Management: Primary Survey Treat the patient, not the burn Every burn patient is a trauma patient Immediate priorities: Airway with cervical spine protection Breathing and Ventilation Circulation Disability, Neurologic Deficit Exposure/Environmental Control
Airway Airway must be assessed immediately Compromised airway may be controlled by simple measures, including: Chin lift Jaw thrust Insertion of an oral pharyngeal airway in the unconscious patient Endotracheal intubation
Three Types of Airway Injuries Carbon monoxide poisoning Inhalation injury above the glottis Inhalation injury below the glottis Any victim found burned in a closed area should be suspected of having an inhalation injury unless proven otherwise
Extensive Facial Burns
Pediatric Facial Burns
Carbon Monoxide Intoxication By-product of incomplete combustion Oxygen competes with carbon monoxide for hemoglobin The more oxygen, the less carboxyhemoglobin Carboxyhemoglobin non-smoker Blood 0-2.3% 0-0.023 Carboxyhemoglobin smoker Blood 2.1-4.2% Most common sign is CNS change (headache, confusion, somnolence, coma) Treatment is 100% oxygen
Breathing and Ventilation Listen to the chest and verify that you hear breath sounds in each lung Assess rate and depth of respiration High flow oxygen is started on each patient at 100% using a nonrebreather Circumferential full-thickness burns
CirculationBlood pressure (manual please!) Pulse rate Skin color (of unburned skin) Insert 2 large bore IVs (may insert through burn tissue if necessary) Doppler pulses in circumferentially burned extremities
Disability, Neurologic Deficit A alert V responds to verbal stimuli P responds to painful stimuli U - unresponsive
Exposure/Environmental ControlRemove all clothing and jewelry Maintain patient temperature Room should be warm Give patients warmed intravenous fluids Dry sheets, hypothermia blankets (bear huggers), radiant barriers are all good methods to keep patients warm
Secondary Survey Completed after primary survey Consists of history and complete head-to-toe examination of patient
History Circumstances of Injury: Flame? Scald? Chemical? Electric?
Medical History: AMPLE (allergies, medication, previous illness/surgery, last meal/fluid intake, events related to injury)
Complete Physical Examination Head-to-toe examination Determine severity of burn
Other Burn Management PrinciplesStop the burning process Universal precautions Fluid resuscitation Vital signs Insert nasogastric tube (if >20% TBSA, since patients are prone to gastric dilatation due to ileus) Insert duotube (for tube feedings keep the gut going)
More Management Principles Insert urinary catheter (urinary output is vital to survival) Assess extremity perfusion Continue respiratory assessment Pain management (morphine please) Psychological assessment
Initial Laboratory Studies Baseline laboratory studies are important: Hemoglobin, hematocrit Electrolytes (initial losses usually Na, Cl and K) BUN, creatinine Urinalysis Chest x-ray
More Laboratory Studies to Consider ABGs (if inhalation injury is suspected) Carboxyhemoglobin ECG with all electric injuries or preexisting cardiac problems Glucose (in children) and diabetics
Shock & Fluid Resuscitation Fluid replacement is part of initial burn treatment Burn tissue causes capillary leaking Endothelial cells separate and become porous Huge amounts of fluid pour out into tissue Blood volume goes down as patients become more edematous (third spacing) hypovolemic shock!
Who is resuscitated? Any burn greater than 10% Depends also on age and health of patient Any inhalation injury Any trauma patient Any electircal burn When in doubt OVER TREAT
The Parkland Formula Goal is to maintain volume during period of hypovolemia ****Resuscitation time is calculated from the TIME OF INJURY, not the time the patient arrived at the hospital!!!**** Use Lactated Ringers for fluid replacement only!!!
The Parkland Formula Continued Adults: 2-4 mL x kg body weight x % burn Children: 3-4 mL x kg body weight x % burn Infants and young children should receive fluid with 5% dextrose at a maintenance rate in addition to the resuscitation fluid noted above
Give fluid in the first 8 hours Give the remaining fluid over the next 16 hours You may need to increase fluid ABOVE the formula to maintain adequate urine output
Why use LR? Isotonic Well, so is normal saline! However, normal saline contains a large amount of chloride Too much chloride to a burn patient creates a potential for metabolic acidosis This is why LR is the fluid of choice!!!
The Color of Pee Patients with electrical injuries will have a lot of myoglobin in their urine So that the myoglobin does not gum up the kidneys, these patients may require more fluid
The Foley tells the Story! If there is only one thing that you could choose to see if your burn patient was doing well, that would be the Foley!
Hourly Urinary Output Adults: 0.5 mL per Kg per hour Children weighing less than 30 kg: 1 mL per Kg per hour Remember this is the minimum amount of urine to expect!
Summary We have reviewed first, second and third degree burns We have applied the Rule of Nines We know the resuscitation formula
Care of the Burn Patient Part IIAlenka Vale, RN, MSN Edited by Jo Teichman, RN, MSN, CWOCN
Objectives Upon completion of this lecture, participants will be able to: Describe the difference between an escharotomy and a fasciotomy Recognize different methods of topical wound management
Escharotomies/Fasciotomies Both are surgical techniques used to restore circulation to an extremity Escharotomy cuts through eschar; typically does not go through the fatty layer Fasciotomy cuts through to the fascia (muscle); you will see exposed muscle
Escharotomy
Escharotomy and Fasciotomy
Escharotomy
Another Patient with Escharotomies
Why use them? Any major burn injury circumferential to an extremity or body part will swell tightly Expect compartment syndrome, especially with circumferential third degree burns As you pour fluid (from the Parkland formula) into the patient, the burns become extremely tight Circulation becomes compromised This can happen several hours after fluid resuscitation
Complications of Edema Complications of edema may effect the ability of the chest to expand This may occur even in an intubated and ventilated patient Chest needs to be able to expand in order for good oxygen exchange to occur Escharotomies in the shape of a square are part of the solution
How is an escharotomy or fasciotomy performed? Physicians may use a scalpel Most use a device called a Bovie A Bovie is a cauterizing machine that simultaenously cuts and cauterizes Potential for bleeding is great during and post-procedure
How do you take care of escharotomies and fasciotomies? Escharotomies typically use the same burn creams prescribed for the area where they are performed Fasciotomies expose muscle; the key is to keep the muscle moist Fasciotomies usually use a non adherent dressing coated with Bacitracin ointment
Topical Wound Management There are many products out on the market for burn care The products and procedures used for a specific burn patient largely reflect physician preference
Silvadene White, antimicrobial cream Sulfa derivative (watch for patients with sulfa allergies!) Has silver Will turn grey on exposure to air May cause the patient to become neutropenic Applied after debridement
Silvadene application
Sulfamylon cream White, antimicrobial cream Diffuses through devascularized areas Typically applied to cartilage (on ears) Does not turn grey like silvadene
Acticoat Is a blue sheet with several layers Contains bactericidal concentrations of silver with patented nanocrystalline technology Smells like fish
Acticoat in Action
Algae Products Many on the market Kaltostat is one popular brand Typically algae is impregnated into dressing form Algae is sterilized and does not look green Used to absorb oozy secretions Donor sites
Debriding Creams Enzymatic debridement creams help debride necrotic tissue or eschar Will also debride good tissue Practitioner needs to be careful in applying These creams are painful! Good pain management is required Santyl is a common marketed brand
The Skin Were In! Deep partial thickness and full thickness burns often require grafting to heal There are different types of grafts: Autograft Homograft Heterograft
Autografts Patients own skin is used Skin is taken from a non-burned donor site Depending on the area to be covered, the autograft may be run through a meshing machine that stretches the autograft Healed area looks like mesh An autograft not run through a mesh is a sheet graft
Donor site for graphs Taken usually from the thigh
Autograft in Action
Sheet Graft Surgery
Donor site for sheet graft
Sheet graft in place
Cultured Epithelial Autografts CEAs Biopsy is taken from the non-burned skin of the patient Cells are grown over a period of 6 weeks to form skin Meshers help expand the CEAs to cover more area on the patient Really, really, really, really, really expensive!!!!!
Homografts/Allografts Terms for skin derived from deceased humans Used as temporary coverings of burn wounds Eventually rejected because of the bodys immune reaction Some homografts are not rejected
Heterografts/Xenografts Skin taken from animals used as a temporary covering for burns Usually pigskin is used Available from commercial suppliers Often, it is impregnated with a topical antibacterial ointment Normally it is rejected, but there have been cases where pigskin has remained on the patient
General Guidelines When autografts or CEAs are to be applied, you must make sure that the patients WBC count is considered to optimize graft take Autografts are left undisturbed for a few days to optimize take Sulfamylon liquid is spritzed over the grafted site Algae-based product is applied over donor site
What happens when you dont have skin to work with? Consider Integra an artificial skin composed of 2 layers: a silicone outer layer that acts as a person's epidermis and a porous matrix that replaces the dermis The porous matrix is biodegraded and reabsorbed The epidermal layer is removed and replaced with grafted skin
Summary We now know the difference between escharotomies and fasciotomies We have discussed different wound treatment options
