88
Q

Systemic Burns: What physiologic changes occur in kidneys?

A

Vasoconstriction

89
Q

Systemic Burns: What physiologic changes occur throughout the body?

A

Altered thermoregulation, immunodepression, hypermetabolism

90
Q

Systemic Burns - Cardiovascular Alterations: Immediate decrease with what?

A

Cardiac output

91
Q

Systemic Burns - Cardiovascular Alterations: Decreased plasma volume in system will lead to what?

A

Hypovolemia, which will lead to hypotension

92
Q

Systemic Burns - Cardiovascular Alterations: Increased workload on heart why?

A

Heart is trying to get oxygenated blood out to the rest of the body because of increased O2 demand

93
Q

Systemic Burns - Cardiovascular Alterations: Inflammatory process kicks in, leading to what?

A

Capillary leaking

94
Q

Systemic Burns - Cardiovascular Alterations: This also acts like shock, which is why they call it burn-shock. What is this?

A

A type of hypovolemic shock. This is due to loss of fluid

95
Q

Systemic Burns - Cardiovascular Alterations: If adequate fluid resuscitation isn’t given, what can patients develop?

A

More of a distributive shock. This is because there will be massive pooling in periphery due to loss of sympathetic tone of these patients.

96
Q

Systemic Burns - Cardiovascular Alterations: A lot of changes has to do with what?

A

Systemic inflammation kicking in and basically causing vessels to be leaking causing fluid shifts.

97
Q

Systemic Burns - Fluid/Electrolyte Alterations: Superifical burn injury will cause what to form?

A

Edema formation to occur, which can usually occur within four hours.

98
Q

Systemic Burns - Fluid/Electrolyte Alterations: Deep burns can cause what to form?

A

Edema to form for up to 18 hours.

99
Q

Systemic Burns - Fluid/Electrolyte Alterations: What happens as these inflammatory mediators are getting released?

A

This is causing fludis and electrolytes to shift into the interstitium.

100
Q

Systemic Burns - Fluid/Electrolyte Alterations: Fluid shifting from burns often leads to what?

A

Compartment syndrome which leads to escharotomy or fasciotomy

101
Q

Systemic Burns - Fluid/Electrolyte Alterations: Big part of this is what is happening to cells, leading to what?

A

A lot of cells are going to be destroyed, which lead to increased potassium levels that happen immediately.

102
Q

Systemic Burns - Fluid/Electrolyte Alterations: What happens to potassium as time goes on?

A

Fluid will begin to shift and you will start to see lower potassium levels

103
Q

Systemic Burns - Pulmonary Alterations: This are either going to involve what?

A

The upper or lower airway

104
Q

Systemic Burns - Pulmonary Alterations: The upper airway typically involved when

A

when there is a direct thermal injury to the head or the neck

105
Q

Systemic Burns - Pulmonary Alterations: When is the lower airway typically involved?

A

There has usually been inhalation injury. Happens below the glottis and vocal cords

106
Q

Systemic Burns - Pulmonary Alterations: Upper airway assessments include?

A

Assess trachea if it becomes edematous, if stridor present , if patients are drooling, difficulty swallowing

107
Q

Systemic Burns - Pulmonary Alterations: What would be some indicators of a lower airway injury?

A

This deals with alveoli. May see impaired gas exchange because alveoli collapsing. May see inflammation causing mucus production causing crackles. Bronchi might constrict.

108
Q

Systemic Burns - Pulmonary Alterations: A big issue for this , especially in lower airway is what?

A

Patients might be taking in CO poisoning, which is a big factor in fatalities.

109
Q

Systemic Burns - Pulmonary Alterations: Why does carbon monoxide poisoning occur?

A

Happens because CO is wanting to combine with hemoglobin. Hemoblogin likes CO more than oxygen, having 200% greater affinity for it. Kicks off oxygen molecules.
