78
3
Q

12
4
Q
____% is the volume of the CSF.
A
10
5
Q
Primary injuryoccurs at the
A
initial time of an injury (e.g., impact of car accident, blunt-force trauma) that results in displacement, bruising, or damage to any of the three components.
- injury on impact
6
Q
Secondary injuryis the resulting
A
hypoxia, ischemia, hypotension, edema, or increased ICP that follows the primary injury.
- after injury (swelling, hypoxia, HTN)
7
Q
Secondary injury, which could occur several
A
hours to days after the initial injury, is a primary concern when managing brain injury
8
Q
cerebral edema
A
increased accumulation of fluid in the extravascular spaces of brain tissue
9
Q
cerebral edema results in an
A
increase in tissue volume that can increase ICP
10
Q
Intracranial pressure (ICP)is the
A
hydrostatic force measured in the brain CSF compartment
11
Q
What maintains the ICP?
A
the balance among the three components (brain tissue, blood, CSF)
12
Q
Factors that influence ICP under normal circumstances are changes in
A
(1) arterial pressure; (2) venous pressure; (3) intraabdominal and intrathoracic pressure; (4) posture; (5) temperature; and(6) blood gases, particularly CO2levels.
13
Q
The Monro-Kellie doctrine states that the
A
three components must remain at a relatively constant volume within the closed skull structure
- displaced, the total intracranial volume will not change.
-This hypothesis is only applicable in situations in which the skull is closed. The hypothesis is not valid in persons with displaced skull fractures or hemicraniectomy.
14
Q

A
ventricles, subarachnoid space, subdural space, epidural space, or brain tissue using a pressure transducer
15
Q

A
5 to 15 mm Hg. *
16
Q

A
considered abnormal and must be treated.*
17
Q
What component is the first to go down when increased ICP?
A
CSF - swelling and edema
18
Q
What goes down next after CSF goes down?
A

20
Q
Herniation
A

21
Q
Cerebral blood flow(CBF) is the **
A
amount of blood in milliliters passing through 100 g of brain tissue in 1 minute**.
22
Q
The maintenance of blood flow to the brain is critical because the
A
brain requires a constant supply of O2and glucose
23
Q
brain uses ___% of the body’s O2and 25% of its glucose
A
20
24
Q
Autoregulationis the
A
automatic adjustment in the diameter of the cerebral blood vessels by the brain to maintain a constant blood flow during changes in arterial blood pressure (BP).
25
purpose of autoregulation is to ensure a
consistent CBF to provide for the metabolic needs of brain tissue and to maintain cerebral perfusion pressure within normal limits
- consistent blood to the brain
- will add or remove O2 when needed by vasodilation or vasoconstriction
26
CBF decreases, and symptoms of cerebral ischemia, such as
syncope and blurred vision
27
High CBF can be affected by
(>150 MAP)
cardiac or respiratory arrest, systemic hemorrhage, and other pathophysiologic states (e.g., diabetic coma, encephalopathies, infections, toxicities
28
Regional CBF can be affected by
trauma, tumors, cerebral hemorrhage, or stroke. – lose elasticity (tx with shunt to get fluid out)
29
CPP =
MAP - ICP
30
CPP
force driving blood into the brain, providing oxygen and nutrients
- ensure blood flow to the brain
31
ICP increased by
intracranial bleeding
cerebral edema
tumor
32
Increased ICP causes
collapsed veins
decrease effective CPP
reduces blood flow
33
primary determinant of cerebral blood flow
CPP
34
Normal CPP is
60 to 100 mm Hg
35
CPP decreases
autoregulation fails and CBF decreases
36
CPP of less than 50 mm Hg is associated with
ischemia and neuronal death.
37
A CPP of less than 30 mm Hg results in
ischemia and is incompatible with life.

42
Cushing's Triad is a __________ emergency
neurological
-ominous development
-rapid fluctuations of VS
43
brain compression s/s
increases, respirations become rapid, the blood pressure may decrease, and the pulse slows further
44
Pressure-Volume Curve
stage 1
high compliance
The brain is in total compensation, with accommodation and autoregulation intact. An increase in volume (brain tissue, blood, or CSF) does not increase the ICP.
45
Pressure-Volume Curve
stage 2
compliance is beginning to decrease, and an increase in volume places the patient at risk of increased ICP and secondary injury.
46
Pressure-Volume Curve
stage 3
significant reduction in compliance. Any small addition of volume causes a great increase in ICP. Compensatory mechanisms fail, there is a loss of autoregulation, and the patient exhibits manifestations of increased ICP (e.g., headache, changes in level of consciousness or pupil responsiveness).
With a loss of autoregulation, the body attempts to maintain cerebral perfusion by increasing systolic BP.
- decompensation is imminent.
- systolic hypertension with a widening pulse pressure, bradycardia with a full and bounding pulse, and altered respirations.
47
Pressure-Volume Curve
stage 4
ICP rises to lethal levels with little increase in volume
-herniation
48
Herniation
occurs as the brain tissue is forcibly shifted from the compartment of greater pressure to a compartment of lesser pressure. In this situation, intense pressure is placed on the brainstem, and if herniation continues, brainstem death is imminent.
49
ICP should be monitored in patients admitted with a
Glasgow Coma Scale (GCS) score of 8 or less and an abnormal CT scan or MRI

Types of Burns
Thermal
Chemical
Electrical
Smoke and inhalation
Cold thermal injury or frostbite
124
Thermal burns, caused by
flame, flash, scald, or contact with hot objects, are the most common type of burn injury. The severity of the injury depends on the temperature of the burning agent and duration of contact time. Scald injuries can occur in the bathroom or while cooking. Flash, flame, or contact burns can occur while cooking, smoking, burning leaves in the backyard, or using gasoline or hot oil.
125
Chemical burns
contact with acids, alkalis, and organic compounds. In addition to tissue damage, eyes can be injured if they are splashed with the chemical. Acids are found in the home and at work and include hydrochloric, oxalic, and hydrofluoric acid. Alkali burns can be more difficult to manage than acid burns, since alkalis adhere to tissue, causing protein hydrolysis and liquefaction. Alkalis are found in cement, oven and drain cleaners, and heavy industrial cleansers.4 Organic compounds, including phenols (chemical disinfectants) and petroleum products (creosote and gasoline), produce contact burns and systemic toxicity.
126
Electrical burns
intense heat generated from an electric current. Direct damage to nerves and vessels, causing tissue anoxia and death, can also occur. The severity of the electrical injury depends on the amount of voltage, tissue resistance, current pathways, surface area in contact with the current, and length of time that the current flow was sustained Tissue densities offer various amounts of resistance to electric current. For example, fat and bone offer the most resistance, whereas nerves and blood vessels offer the least resistance. Current that passes through vital organs (e.g., brain, heart, kidneys) produces more life-threatening sequelae than that which passes through other tissues. In addition, electric sparks may ignite the patient's clothing, causing a flash injury.
- Take path of least resistance – skin and vessels to muscle and bone
127
Smoke and inhalation burns
noxious chemicals or hot air can cause damage to the respiratory tract. Three types of smoke and inhalation injuries can occur: metabolic asphyxiation, upper airway injury, and lower airway injury. Smoke inhalation injuries are a major predictor of mortality in burn patients. Rapid initial and ongoing assessment is critical. Airway compromise and pulmonary edema can develop over the first 12 to 48 hours.
128

White, dry, leather like texture
No nerve endings = no pain
137
Full-Thickness Burns skin destruction
Dry, waxy white, leathery, or hard skin. Visible thrombosed vessels. Insensitivity to pain because of nerve destruction. Possible involvement of muscles, tendons, and bones
138

Indicated, contractions
Indicated O2, 2 IVS, analgesics, possible intubation
Contra – cool room
142
Inhalation Injury s/s
Blisters, edema
Difficulty swallowing
Hoarseness
Stridor
Retractions
Total airway obstruction
**Damage mucosa**
soot
143
Metabolic Asphyxiation
primarily carbon monoxide (CO) or hydrogen cyanide. Oxygen delivery to or consumption by tissues is impaired. The result is hypoxia and, ultimately, death when carboxyhemoglobin (i.e., hemoglobin combined with CO) blood levels are greater than 20%. CO and hydrogen cyanide poisoning may occur in the absence of burn injury to the skin.
144
Upper airway injury
swelling can be massive and the onset rapid. Flame burns to the neck and chest may make breathing more difficult because of the burn eschar, which becomes tight and constricting from the underlying edema. Swelling from scald burns to the face and neck can also be lethal, as can external pressure from edema pressing on the airway. Mechanical obstruction can occur quickly, presenting a true airway emergency.
145
Lower airway injury pulmonary edema occurs after
12-48 hours after the burn - ARDS
146
Do you wait for intubation with inhalation injuries?
no
Do not wait for intubation due to swelling
Burnt skin and mucosa become tight and lead to mechanical obstruction
147
Electrical Injury
Masked marauder – under the skin is a tunneling mess going through everything from path of least resistance but only appears as a tiny hole
- EKG for dysrhythmias, SEVERE METABOLIC ACIDOSIS, AND MYOGLOBINURIA
148
How to tell the extent and depth of burn injuries?
Rule of Nines, Lund-Browder, or the Berkow charts calculate the total body surface area (TBSA) burned
The Rule of Palms can be used for scattered burns
149
Explain the Rule of 9s
Head front = 4.5%
Head Back = 4.5%
Upper chest and lower chest
and same with the back = 9% each
each leg as a whole is 18%
each arm is 9%
150
Palmar Method explaned
The pt palm is 1%
-scattered burns
151
Referral Criteria for burn victims
**1. Partial-thickness burns >10% of total body surface area (TBSA)**
2. Burns that involve the face, hands, feet, genitalia, perineum, or major joints**
3. Third-degree burns in any age group**
4. Electrical burns, including lightning injury**
5. Chemical burns**
6. Inhalation injury**
7. Burn injury in patients with preexisting medical disorders that could complicate management, prolong recovery, or affect mortality risk (e.g., heart or kidney disease, diabetes)
8. Any patients with burns and concomitant trauma (e.g., fractures) in which the burn injury poses the greatest risk of morbidity or mortality. In such cases, if the trauma poses the greater immediate risk, the patient may be initially stabilized in a trauma center before being transferred to a burn center. The HCP will need to use his or her judgment, in consultation with the regional medical control plan and triage protocols.
9. Burn injury in children in hospitals without qualified personnel or equipment needed to care for them
10. Burn injury in patients who will require special social, emotional, or long-term rehabilitative intervention
152
Associated Trauma for Burn victims
Remember the ABCs of trauma
Burns and inhalation injury frequently mask other injuries
Fractures
Spinal cord injury
Other trauma
- fluid and electrolytes shift
- inflammation and healing
- immunity
153
Fluid and Electrolyte Patho for burns
Fluid and Electrolyte shift
Inflammation and Healing
Immunologic Changes
Decrease vascular volume – cap becomes permeable (interstitial)
Decreased cardiac output
Increase blood viscosity
154
Inflammation and Healing patho for burns
Burn injury to tissues and vessels causes coagulation necrosis. Neutrophils and monocytes accumulate at the site of injury. Fibroblasts and newly formed collagen fibrils appear and begin wound repair within the first 6 to 12 hours after injury
155
immunity patho for burns
skin barrier to invading organisms is destroyed, bone marrow depression occurs, and circulating levels of immunoglobulins are decreased. Defects occur in the function of white blood cells (WBCs). The inflammatory cytokine cascade, triggered by tissue damage, impairs the function of lymphocytes, monocytes, and neutrophils. Thus the patient is at a greater risk for infection.

168
Mature healing is reached in about
12 months when suppleness has returned, and the pink or red color has faded to a slightly lighter hue than the surrounding unburned tissue.
169
A patient who is admitted to a burn unit is hypovolemic. A new nurse asks an experienced nurse about the patient’s condition. Which response if made by the experienced nurse is most appropriate?
“Blood loss from burned tissue is the most likely cause of hypovolemia.”
“Third spacing of fluid into fluid-filled vesicles is usually the cause of hypovolemia.”
“The usual cause of hypovolemia is evaporation of fluid from denuded body surfaces.”
“Increased capillary permeability causes fluid shifts out of blood vessels and results in hypovolemia.”
“Increased capillary permeability causes fluid shifts out of blood vessels and results in hypovolemia.”
