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

15

Inhibit synthesis of PGs

NSAIDs
