5. Chemical burns.
6. Inhalation injury.
7, Burn injury in pts with preexisting medical disorders that could complicate management/prolong recovery (heart or kidney disease)
8. Any pt with burns and trauma (fractures). Stabilize in trauma center then transfer to burn center.
9. Burn injury to pts who will require special social, emotional, or long-term rehabilitative intervention.
What is a first degree burn?
Partial-thickness.

Erythema, blanching on pressure.

Sunburn, quick heat flash

Partial-thickness

Has blisters and severe pain

Flame flash, scald, contact burns, chemical, tar, electric current.
What is a 3rd and 4th degree burn?

dry, waxy white, leathery, or hard skin; visible thrombosed vessels; insensitivity to pain b/c of nerve desctruction

flame, scald, chemical, tar, electric current

Surgival intervention required.
When calculating TBSA burned, what do you not include?
First degree burns like a sunburn.
What complication do burns to the face and neck have?
Affects respiratory function
What complication does a burn to the hands, feet, joints, or eyes have?
Makes self-care difficult
What complication do burns to the ears and nose have?
Infection due to poor blood supply to the cartilage.
How do you treat small thermal burns <10% TBSA?

>10% TBSA?
Cover with a clean, cool, tap water-dampened towel

ABC's, gently remove burned clothing, leave adhered clothing
How long do you cool a large burn?
No longer than 10 min to prevent hypothermia

Never cover a burn with ice as this causes vasoconstriction and reduces blood flow to the burn.
What is the first aid for chemical burns?
Flush with copious amounts of water and remove clothing containing the chemical.

Brush dry chemical from skin before irrigation.

Flush from inner to outer corner of eye with water unless lactated Ringer's is available.
What do you do for pts that you suspect CO intoxication?
100% humidified O2
What is the emergency management for thermal burns?
ABC's
Stabilize cervical spine.
Assess inhalation injury.
O2
Remove clothes
Cover burned areas with dry dressings or clean sheet.
Establish IV access with 2 large-bore cathters if burn >15% TBSA
Insert cathetar
Elevate burned limbs
Administer IV analgesia
What is the emergent phase of burn injury?
Time of burn - 72 hours post burn

Worry: hypovolemic shock/edema

3rd spacing - blisters, edema in nonburned areas

Water, Na, and protein move in to interstitial spaces

Complications: hypovolemic shock, dysrhythmias, airway injury
What are the 3 biggest worries with burn injuries?
Pneumonia from inhalation injury as it is the leading cause of death.

Thromboembolism

Acute tubular necrosis (adequate fluid replacement can counteract this)
What antitoxin do we give burn pts?
Tetanus
What is the Parkland Formula?
Lactated Ringers:

4ml x body weight in kg x %TBSA burned

Give 1/2 in first 8 hour, 1/4 in next 8, 1/4 in last 8 hour
How do we assess the adequacy of fluid resuscitation?
Urine output!!

1ml/kg/hr or 75-100ml/hr for pt with hemoglobinuria/myoclobinuria

MAP >65mmHg

Peripheral measurement is invalid due to vasoconstriction and edema.
How do you do wound care for a burn pt?
Shower once daily with a dressing change in the am, dressing change in pt room in the pm.
What sort of PPE do you need when burns are exposed?
Disposable hats, masks, gowns, gloves

Sterile gloves when applying ointments and dressings
Temp of a burn pts room should be...
>85 degrees b/c of loss of heat regulation
How do you position a pt with burns to their ears?
No pillows!! Use a rolled towel under the shoulders to hyperextend the neck.
How often do burn pts get perineal care?
1-2 times/day
When is PT started on a burn pt?
Immediately, sometimes during showering/dressing changes. Early ROM to facilitate mobilization of fluid and prevent contractures.
What kind of pain meds do burn pts get early?
IV b/c GI function is slowed
What immunization do burn pts get and why?
Tetanus b/c of the likelihood of anaerobic burn wound contamination
What kind of meds do burn pts get?
Analgesia (morpine, fentanyl, NSAIDS, methadone, neurontin)

Sedation/hypnosis (Haldol, Ativan, Versed, Ambien)

Antidepressants (Zoloft, Celexa)

Anticoagulants to prevent DVT

Nutritional support (vit A, C, E, Zn, Fe and oxandrolone (Oxandrin) to promote weight gain and preservation of lean body mass)

GI support like ranitidine (Zantac) and esomeprazole (Nexium) to prevent Curling's ulcer and nystatin to prevent thrush
What allergy do we ALWAYS check for in burn pts??
Sulfas b/c many burn creams contain sulfas.
What sort of nutritional therapy do burn pts get?
Early enteral feeding to preserve GI function
What is the acute phase of burn injury?
The 2nd phase where there is mobilization of extracellular fluid and diuresis. May take weeks-months.

Worry about Na and K balance!!!
Worry about delirium at night especially with the elderly!!
Worry about hyperglycemia due to stress response!!
What interventions do you do during the 2nd phase of burn injury (acute phase)?
Encourage stretching and movement of burned body parts.

Feed pt as soon as possible to prevent Curling's ulcer.
What is Curling's ulcer?
gastroduodenal ulcer caused by stress response resulting in decreased mucus production and increased gastric acid secretion.

Feed pt ASAP!!!!
What are the function of blebs in burn care nursing?
With facial grafts, the unmeshed sheet graft is left open so bleb form between the graft and the recipient be so that the graft does not permanently attach to the wound bed. Evacuate blebs by aspirating with a TB syringe.
What do you have to do with full-thickness burns before they heal?
Excision and grafting
What is a CEA?
Cultured epithelial autograft - graft grown from biopsy specimens obtained from the pts own unburned skin

Be careful to prevent shearing injury and infection
What is Integra?

AlloDerm?

skin harvested from cadavers that is decellularized to render it immunogenic
When is the best time for exercise?
During and after wound cleansing when the skin is softer and bulky dressings are removed.
How do you prevent contractures when there are neck burns?
Have pt sleep without pillows or with the head hanging slightly over the top of the mattress to encourage hyperextension.
What do you do before you start feeding a pt after extubation?
Swallowing assessment!!
What is the rehabilitative phase of burn injury?
The 3rd and last phase when the burn wounds have healed and the pt is able pt is able to resume ADL's.

Interventions include:

Pressure garments to minimize scarring (don't wear over unhealed wounds, take off only during short periods while bathing)

Use H2O based moisturizers and Benedryl for itching.

Keep burns away from sunlight for 3 months to prevent hyperpigmentation.
What is the most common complication during the rehabilitative (3rd phase) of recovery?
Contracture

Avoid flexed position during healing. Use positioning, splinting, and exercise.
What is a common emotional response in the rehabilitative phase?
Regression which can be healthy.
