Tissue Integrity/Burns lecture Flashcards
Burn prevention tips
- Working smoke and carbon monoxide detectors
- Create emergency escape plans
- Never leave cooking food or open flames unattended
- Install childproof devices
- Never leave young children unattended in kitchen/bathroom
- Check electrical cords for damage
- Keep fire extingushers and practice Stop, drop, and roll
- Set home water heater to 120 degrees
- Wear protective clothing, use suncreen, avoid tanning beds
- Do not smoke or have flame in room with oxygen in use
Name the types of burns
Thermal
Electrical
Chemical
Radiation
- Burn caused by fire, steam, scald, hot objects or liquids
- Erythema, edema, blisters, and pain
Thermal
- Burns caused by contact with lightning or electrical energy source
- Can affect multiple organs, cause neuro problems, or cause sudden cardiac arrest
Electrical
- Burns caused by contact with industrial/household chemicals
- i.e Acids, alkalis, organic
- PPE is needed to avoid exposure to chemicals
- Chemical needs to be removed with continuous irrigation with water
Chemical
- Burns caused by sunning, tanning, x-rays, radiotherapy, nuclear accidents
- Erythema, edema, blisters, and pain
- Prolonged exposure can cause N/V/D, HA, fever, fatigue
Radiation
What burn depth is this?
- Pink/red
- Pain
Superficial
What burn depth is this?
- Blisters
- pink/red
- pain
- blanches
Superficial partial-thickness
What burn depth is this?
- Blisters
- waxy
- pink/cherry red
- edema
- no blanching
- pain around edges
- decreased sensation
Deep partial thickness
What burn depth is this?
- Leathery
- dry
- white,tan,brown, black eschar
- No blanching
- No pain
Full Thickness
How long do superfical burns take to heal? Do they leave scars?
3-7 days no scars
Most common superficial burn
Sunburn
Healing time for Superficial burns
1-2 wks
Superfical and superfical partial thickness burns are considered what type of burns?
Minor
How to treat minor burns
- Cool compress or cool water
- Provide analgesics
- Use lotion on intact skin
- Cleans with mild soap and tepid water
- Apply antimicrobial agent to non–intact skin
- Apply dressing if clothing is irritating
- Drink plenty of fluid
- Teach to observe for infection
How long do partial thickness burns take to heal and do they leave a scar? How is it treated? What is a challange associated with this type of burn?
- Healing can take 3-6 wks and can leave scaring
- Surgical debreidment or skin grafting can be required
- It is challenging to determine the true extent of the injury if it will heal or require surgical intervention
Full thickness burns require what? or what won’t happen?
Surgical excision and grafting, healing
Name the three phases of burn wound healing
Inflammation
Proliferation
Remodeling
Name this stage of burn wound healing
Begins immediately after injury, vasodialation, increase in capillary permeability
Inflammation phase
Name this stage of burn wound healing
2-3 days after burn, granulation tissue tissue forms, epithelial cells cover wound
Proliferation phase
Name this stage of burn wound healing
May last for years, collagen fibers reorganize, scars contract, fade
Remodeling phase
Amount of body burned that guides fluid resuscitation ____ for adults
less than or equal to 20%
Rule of Palm
Burns
1% to quickly estimate for scattered burns
Rule of nines
burns
Most common method with body broken into areas of 9% or multiples of 9
Underestimating TBSA burned can lead to what
pt going into shock and organ failure, burn shock
Overestimating TBSA burned can lead to what?
pt unable to tolerate and may develop pulmonary edema
Small burns can be ____ in older adults
Fatal
Factors that determine severity of burns
- Presence of inhalation injury
- Pt age
- PMHx
- Presence of contamination injury
- Anatomical location of burn
Important considerations for infants and children with burns
Be alert to s/s of child abuse when hx does not match injury
Important considerations for adolescents with burns
Foreward about edema or changes in body from injury response
When treating a pregnant woman with burns the nurse should be aware of what?
- Tx of mother threatens fetus
- relationship between percentage of TBSA involved and fetal maternal survival
Considerations for older adults with burns
- Greater risk for death
- may not tolerate fluid resuscitation and surgery
- Skin is less elastic and harder to heal
Rule of palm
1% to quickly estimate for scattered burns
Rule of nines
Most common method with body broken into areas of 9% or multiples
Lund and Browder classification
TBSA
Method of measuring TBSA burned used in a majority of burn centers. Takes into account surface area r/t age, are assigned to each body part.
Name percentages
Name percentages of body for TBSA
Head to toe
Head: 9%
Anterior: 18%
Posterior: 18%
each arm: 9%
Each hand: 1%
Perinium: 1%
Each thigh: 18%
Functional changes burn injuries are:
- Long-term morbidity
- Impaired function: burns to hands, feet, genitalia, perineum, and major joints
- Altered appearance: burns to face
- May require multiple lifelong plastic and reconstructive surgeries to maintain function
Burn injuries effect on respiratory system
- Inhalation injury
- Upperairway injury
- Lower airway injury
- Carbon monixide poisoning
- Airway management
What increases mortality risk in burn patients?
Inhalation injury
Most important factors in burn patients
- depth/extent of burn
- Patient age
- Inhalation injury
How long after burn injury can inhalation injury occur?
24-48hrs
Airway management for burn patients
- 100% humidified o2
- Cough/deep breathing
- Elevate HOB
- ET intubation
What should you always suspect in a burn patient?
That they were injured/trapped in an enclosed space or if they have face, neck, or chest burns.
