Q

Disaster triage: expectant

A

Patients have lethal injuries and usually will die despite treatment.

Examples include devastating head injuries, major third-degree burns over most of the body, and destruction of vital organs. Retriage of this group may be done as resources become available

Q

Disaster triage: immediate

A

Patients have life-threatening injuries that probably are survivable with immediate treatment.

Examples are tension pneumothorax, respiratory distress, major external hemorrhage, and airway injuries.

Ideally, with limited resources, the only patients categorized as red will be those who would benefit from immediate short-duration treatment and then could be retriaged as yellow

27
What do you want to do with a sucking, open chest wound
You want to tape down 2 sides and leave one side, --- you want o occlude it to increase the intrathoracic pressure
28
How do we manage a hemorrhage
``` Assess for s/s shock Fluid resuscitation Stop bleed Apply pressure proximal to the wound Tourniquet as last result ```
29
What are the nursing goals for managing hemorrage
Control bleeding Maintain adequate circulation blood volume Prevent shock
30
You walk into a room, and you see blood on the bed. What else, besides the blood would tell you that the patient is in shock?
``` Pale, cool, diaphoretic Anxious HR up BP down Delayed cap refill RR up ```
31
What kinds of fluids are you going to give someone with a hemorrhage?
Isotonic - LR, NS Colloids - albumin Blood products

Tournequete
33
What are things to keep in mind with wounds?
Caution with clipping hair - can get into wound Never remove eyebrow hairs Cleanse site with NS No antibacterial until thorough cleansing Closure Delayed closer
34
delayed closure may be due to what
tissue loss | high potential or infection
35
Intra-abdominal injuries: Penetrating - Gunshot and stab
Typically go straight to surgery Assess small bowel and liver Extensive tissue damage Looking for enter and exit for gunshot
36
Intra-abdominal injuries: Blunt (MVA, explosions, falls)
Challenging Delayed care Blood loss into peritonial cavities check H&H
37
Intra-abdominal injuries: assessment
``` H/H ABG Abdominal assessment Vitals INR WBC Pain ```
38
Intra-abdominal injuries: internal bleeding
CT scan to see where its at | liver and spleen (because they impact clotting)
39
Intra-abdominal injuries: intraperitoneal injury
``` Tenderness Rebound tenderness Guarding Rigidity Spasms Increased distention Pain ```
40
Intra-abdominal injuries: Geritourinary injury
Rectal or vaginal inspection
41
Crush injuries
Assess for hypovolemic shock spinal cord injury check they dont go into rhabdomyelosis
42
Heat induced illness
Heat stroke - make sure we hydrate and keep them cool
43
Frostbite
want to check for this, especially in homeless population - remove restrictive clothing (compartment syndrome) - pain meds - elevate extremitity to decrease swelling - stick sterile gauze on it because skin might stick to frostbite (toes)
44
Hypothermia
When core temp is less than 95 degrees You want them to be really warmed
45
nonfatel drowning concern
hypoxia and acidosis
46
ingested poison
control airway - ventilation, oxygenation - then stabilize cardiovascular
47
nonfatal drowning
Someone was found in water, but they did not die in first 24 hours after drowning

50
Snakebites - what causes the damage?
Proteins that broad range of physiologic effects - neuro, respiratory, cardiac
51
Snakebites s/s
edema, ecchmyosis, hemorrhagic bullae - leading to necrosis of site - lymphnode tenderness, n/v, numbness, metallic taste in mouth. Without treatment, these s/s can progress to fasciculations, hypotension, paresthesias, sz., coma
52
What is the initial first aid at the site of a snakebite
``` Have person lie down Removing constrictive items (rings) Provide warmth cleanse wound Cover wound with lite, sterile dressing Immobilize the injured body part BELOW heart ABC = priorities NO - ice, incision, suction, or tournequette Tetanous and analgesia should be given ```
53
snakebites: Initial evaluation in the ED is performed quickly and includes information about the following:
Whetdiscourage bringing the snake for identification—even a dead snake’s venom is poisonous. Sequence of events, signs, and symptoms (fang punctures, pain, edema, and erythema of the bite and nearby tissues). Severity of poisonous effects. Call the local poison control Vital signs. Circumference of the bitten extremity or area at several points. Laboratory data (complete blood count, urinalysis, and coagulation studies).
54
Disaster nursing
Man made or natural event that overwhelms community resources - disaster plans - natural disasters - biologic agents --> must do greatest good for greatest number of people
55
What are the zones of burns (aka, pathophysiology)
A. Zone of coagulation (tissue is completely destroyed) B. Zone of stasis (nonviable tissue and potentially viable tissue) C. Zone of hyperemia (increased blood flow secondary to the natural inflammatory response)
56
What variables impact the prognosis of burns
``` severity of the burn Presence of the inhalation injury association injuries age comorbid conditions ```
57
Gerontological considerations with burn injuries
Morbidity and mortality rates are greater Loss of SQ tissue increases risk for deep injury Decreased sensation Changes in vision
58
How can we help elderly prevent burns
``` Backburners on stove lower water heater smoke detector checks loud smoke detector carbon monoxide detectors fire extinguisher escape plan sprinkler systems no smoking on oxygen ```
59
how are burns classified?
classified according to the depth of the burn - how it occurred - causative agent - temp of burning agent - duration of contact with burning agent - thickness of the skin in the burned area
60
What are the types of burns
Superficial Superficial partial thickness Deep partial-thickness Full-thickness injury
61
there will be pix on the midterm you will need to know the type of burn it is
k
62
Superficial burn
``` Formally known as 1st degree Only epidermis injured Redness and edema No blisters Heals in about 3 days or less with no scarring ``` ex. sunburn, curling iron, stove
63
Superficial Partial-Thickness brun
Examples: sunburn, low intensity electrocurrent Epidermis injured, may extent to the dermis The exposed dermis is red, blanches with pressure, dry Tingling, hyperparesthesia, pain (soothed by cooling) Hair still intact Heals within 5-10 days Peeling possible No scarring
64
Deep partial thickness burn
Extends to the reticular layer of the dermis s/s: pain, hyperparesthesia, sensitive to cold air Wound appearance: - blistered, broken epidermis, weeping surface, edema, mottled red base Increased risk for infection Heals in 3-8 weeks, some scarring and depigmentation
65
Deep partial thickness burn example
scalding
66
What is a risk for a deep partial thickness burn?
Compartment syndrome d/t swelling - take of restrictive clothing
67
Full thickness burn: ex
flames, prolonged exposure to hot liquids, chemicals
68
Full thickness Burn
Total destruction of the dermis and extends into the subutaneous fat - can involve muscle and bone
69
Full thickness burn s/s
pain free shock hematuria with possible hemolysis possible entrance
70
Full thickness - wound color
mottled white to red, brown, or black
71
Full thickness burn - skin
dry, pale white, charred and leathary, edema, eschar, slough Hair follicles and sweat glands destroyed
72
Full thickness: healing
Does not happen spontaneously, requires surgery or grafting
73
How to estimate total body surface area (TBSA)
Rule of nines
74
What percentage of the body for Rule of Nines for the following: head, each arm, torso, genitals, each leg
``` Head: 9% (4.5% front, 4.5% back) Each arm: 9% (4.5% front, 4.5% back) x2 Torso: 36% (18% front, 18% back) Genitals: 1% Each leg: 18% (9% front, 9% back) x2 ``` neck is considered part of the head
75
Management of fluid loss and shock with burns
IV resuscitation formulas used as a guide Patient's response to fluid resuscitation determine fluid therapy Parkland Formula: 2mL of LR x Kg x % TBSA (normal) 4mL of LR x Kg x % TBSA (children and electrical burns)
76
When is fluid resusitation the most important for burn victims?
first 8 hours
77
go practice parkland formula
go
78
Classification of burn injury extent
minor burn injury Moderate uncomplicated burn injury Major burn injury
79
Minor burn injury
less than 15% TBSA
80
What are considered the major burn areas?
``` Eyes ears face genitalia hands feet ```
81
What do burns of 60% TBSA cause?
Depressed myocardial contractility - plus a loss of circulating plasma volume, hemoconcentration and massive edema formation - distributive and hypovolemic shock
82
When is fluid loss the greatest for a burn victim
First 4-8 hours - this is why we bolus them half the amount we calculate from the parkland formula
83
When does capillary integrity return after a burn
toward normally 36-48 hours after the burn
84
Burn shock
Think hypovolemia - "leaky, third spacing" of fluid, severe hypovolemia and CO
85
Burn shock: initial systemic event - hemodynamic instability
Shift of fluid, sodium and protein from the intravascular space into the interstitial spaces In major burns – this process exceeds the useful effect of the inflammatory response Progressive edema develops in unburned tissue and organs causing hypoperfusion and hypovolemic shock Cardiac Output and BP drop Increase in peripheral vascular resistance secondary to edema formation, decrease in blood volume and decrease in CO
86
Burn shock alterations:
``` Fluid electrolyte Pulmonary Renal Immunologic Thermoregulatory GI ```
87
Fluid and electrolyte alterations (burns)
Edema begins quickly after burn. - Potassium increase – massive cell destruction - Sodium depletion – plasma loss or as water shifts from the interstitial space and returns to the vascular space - RBC decrease – destroyed or damaged - Hct elevated – plasma loss - Thrombocytopenia, coagulation abnormalities, prolonged clotting time
88
Fluid and electrolyte alterations: treatment
Elevation of extremity Remove eschar Escharotomy Fasciotomy
89
Burns > 30% TBSA, inflammatory mediators stimulate local and systemic reactions resulting in what
extensive shift of intravascular fluid, electrolytes, and proteins into he surrounding interstitium.
90
Pulmonary alterations (BURNS)
Occurs even when lung tissues have not been damaged directly - upper airway injury - inhalation therapy - patient at risk for ARF and ARDS
91
inhalation injury usually related to what
carbon monoxide
92
ABC - what is most concerning with burns
Circulation - unless there is an inhalation injury
93
Cardiovascular changes - burns
Hypovolemic shock - monitor vitals and cardiac rhythm, especially in cases of electrical burn injuries
94
What are the nutritional needs of a burn patient
Patient may require > 5,000 calories/day in large burns High calorie/protein May require supplemental feedings to meet nutritional requirements
95
Vascular alterations for burn victims
Fluid shift | - fluid imbalance, electrolyte, acid-base (hyperkalemia, and hyponatremia, and hemoconcentration)
96
Renal impacts of burns
May be altered as a result of decreased blood volume
97
Immune system impact of burns
immune system diminishes resistance to infection (sepsis)
98
thermoregulation - burns
loss of skin also results in an inability to regulate body temp
99
GI complications of burns
paralytic ileus and Curling's ulcer
100
ABC - burns
Circulation, airway, breathing, disability
101
What kind of analgesia are we going to give burn patients
IV meds typical morphone
