36
What is the most common type of burn?
Thermal burns
37
How do we measure "extent of burn?"
% TBSA (total body surface area) rule of 9's (%)
38
What burn extent is considered a major burn?
partial or full thickness burn >20% TBSA
39
How many stages (classification) are there of burn and what are they called?
1st degree - superficial partial thickness 2nd degree- deep partial thickness 3rd & 4th degree- full thickness
40
What stages can a person regenerate their skin when burned and what is the condition required for this?
Superficial partial thickness and deep partial thickness IF there is some dermis left to regenerate
41
What stage burn is skin glossy, red, blisters/swelling?
Deep partial- thickness burn
42
what does Full thickness burn look like?
dry, dark skin looks charred no blisters dermal layer is gone
43
Which type of burn does not have pain and why?
Full thickness burn b/c nerve endings are destroyed
44
What is escharotomy and why is it performed?
A cut through eschar tissue b/c of inflammation that causes compartment syndrome under the eschar - circumferential burn (all the way a round a limb/torso)
45
When we talk about burns, what is the difference between "extent","kind" , and "classification" ?
kind = thermal, chemical etc. (cause) Extent = TBSA % burned classification - degree
46
How long is the emergent (resuscitation) phase of a burn?
24-48 hours
47
What is the goal during the emergent burn phase?
Save their life
48
What is the major problem in the emergent stage we are concered with?
capillary leak = fluid shifts Leaks OUT of the vascular system so BP plummets = changes in vitals
49
How long is the acute stage of burn?
48-72 hours
50
What is the major problem in the acute stage we are concerned with?
Capillary leak stops = diuresis - vital changes - fluid overload (HF careful) - lytes imbalance
51
How long is the rehabilitative phase of burn?
2 weeks up to 7-8 months
52
What is the major issue in rehabilitative burn?
Adjusting to living
53
What is important to observe around the face of someone in the emergent phase and why?
-Soot/smoke around their face. -singed facial hair Respiratory can still be compromised
54
What are 5 warning signs during emergent phase that there's a change in resp.?
1.SOB 2. wheezing and/or stridor 3. voice change-hoarsness 4. drooling 5. swallowing difficulty
55
Do we assess circulatory system first or Airway first and why in emergent stage?
Airway. b/c you can have blood circulating well but if there's no gas exchange, we have useless blood
56
what HR do we want to stay under in burns in emergent phase?
<120 bmp
57
what systolic BP do we want to stay under in burns during emergent stage?
>90
58
during the emergent stage, will K+ be high or low and why?
High b/c of tissue damage Put on heart monitor
59
during emergent stage, will Na be high or low?
Na will be low because water leaves the vascular system and Na follows
60
What are the priorities during the emergent stage?
1. Airway 2. fluid therapy 3 &4. Wound care & analgesia & immunization tetanus 5. infection
61
What type of AKI can happen in burns and why?
intrarenal AKI d/t rabdo because of the intense tissue damage in the body
62
What are the 2 goals of the acute stage of burn?
1. fighting infection 2. support wound healing (nutrition)
63
Why is nutrition important for someone in the acute phase of burn ?
because they are hypermetabolic
64
Which phase of burn can require multiple trips to the OR for debridement/grafting?
Acute phase
65
In what phase do we get the burn patient moving to avoid contracture?
Acute phase
66
What phase of burn is psychological care especially important?
Acute phase
67
What phase is pain management very important?
acute phase
68
What does acticoat have in it and how many days does it stay on?
Acticoat has silver Sterile water activates the silver and that kills broad spectrum of bacteria 3-7 days then change
68
What do nurses focus on in the acute stage of burn?
Wound care: prevent infection promote healing Clean/debride take care of donor site
69
What is Flamazine?
An anti-microbial cream that is sometimes used
69
What is the gold standard for burn dressing?
Acticoat
70
What two dressings are most used for burns?
1. Acticoat 2. Adaptic
71
What is debridement?
removing necrotic tissue
72
What are the 5 types of skin grafts?
1. *autograft 2. CEA (cultured epithelian grafts - slow, 8-12 weeks) 3. artificial skin 4. Allograft (human cadaver skin) 5. Xenograft (animal)
73
What is used in the rehabilitation phase to help prevent lifting and scaring?
compression garment
73
What dressing are donor sites covered with?
Hydrophillic foam dressing after harvesting
74
What type of nutrition is required in the rehabilitation phase of burn?
normal diet as tolerated
75
How long should people keep their grafts out of the sun for?
at least the first year
76
What are the primary goals of rehabilitation phase?
1. wound care as required 2. functional support
77
What disease affects wound healing for those with burns?
Diabetes melitis
78
What disease affects fluid status for those with burns?
heart issues - fluid overload
79
What are the 5 things we do for frostbite?
1. soak in lukewarm bath slowly 2. Analgesics 3. Elevate affected limb - b/c inflammation 4. monitor for compartment syndrome 5. Antibiotics - if infection/tetanus shot
80
What 2 things do we not do for frost bite?
1. do not rub the skin 2. no heavy blankets or hot water
80
What is demarcate?
the end of healthy tissue and the beginning of dead tissue
81
What is sepsis?
An extreme response to infection that can cause tissue damage, organ failure and death if not treated quickly
82
What can sepsis lead to if not treated quickly?
septic shock
83
What are the possible signs of sepsis?
low O2 Fast RR dysuria/anuria cognition and affect changes Fever signs of infection BP drops b/c fluid shifts out of cells = lack of tissue perfusion = shut down
84
Who are 5 patients at high risk for septic shock?
1. Immunocompromised 2. Large open wound- burns 3. Invasive procedures- burns 4. Age over 80 5. Chronic illness
85
what is the MAIN problem in septic shock?
Low perfusion = organ ischemia = organ shut down
86
What are early signs of septic shock?
Elevated HR, decreased BP Skin warm and flushed – body is trying to compensate by increasing CO Restless, confused
87
What are the late signs of septic shock?
Cold, clammy Mottled- purple dusky colour Bradycardia and decreased BP Lactate increase (anaerobic metabolism that kidneys can’t deal with) = acidosis Anuria = no urine output
88
What are the 5 things we do for someone in septic shock in the first hour?
1.Measure Lactate level 2.Obtain blood cultures 3.Administer broad-spectrum antibiotics 4. Rapid administration of IV crystalloid fluid for hypotension 5. Vasopressor if blood pressure low after fluid resuscitation
