1
Inflammatory Response: Fever
What is the onset triggered by?
the release of cytokines, especially PGs
2
What do PGs especially cytokines do to get a fever going?
PGs: tell hypothalamus to raise set point
-hypothalamus tells ANS to shiver, reduce sweating, reduce peripheral blood flow
-epinephrine increases metabolic rate
-body increases heat production and conservation to reach set point
-body is hot yet person feels chilled and seeks warmth to reach set point
-
3
What are the beneficial defense mechanisms that fever triggers?
-increased killing of microorganisms
-increased phagocytosis
-increased proliferation of T cells
-increased interferon activity
4
What are some ways to promote health during inflammation?
-prevention of injury (infection, trauma, surgery, and contact with potentially harmful age)
-adequate nutrition and hydration
-early recognition of inflammation (so you can rest or get medication)
-immediate treatment
5
Acute care management:
What are the classic manifestations of inflammation?
malaise or "just not feeling well" (immunosuppressed = corticosteriod use, chemotherapy)
6
Explain the 3 aspects of fever management in acute care.
-determine cause
-administer antipyretic or antibiotic
-monitor for seizures or delirium (>104)
7
What do antipyretics do for a patient?
-relieve stress to the patient and provide comfort
8
What type of response does someone taking corticosteroids or an older adult have to fever?
-blunted response to fever
-illness may be severe (but the older adult/ person on steroids will have a blunted response)
9
If a patient has had antipyretics what other treatment can be performed to lower body temperature?
sponge bath
cooling blankets
10
Why wont a sponge bath or cooling blankets work without antipyretics?
because shivering is the body's way of increasing body heat
11
Drug Therapy Inflammation:
Antipyretic
Acetaminophen
Salicylates (Aspirin)
NSAIDS
12
Drug Therapy Inflammation:
Antiinflammatory
Salicylates (Aspirin)
NSAIDS
Corticosteroids
13
Inhibit synthesis of PGs. Lower temperature by action on heat-regulating center in hypothalamus, resulting in peripheral vasodilation and heat loss
Salicylates (Aspirin)
NSAIDS
14
Interfere with tissue granulation, induce immunosuppressive effects (decreased lymphocyte synthesis), prevent liberation of lysosomes
corticosteriods
