SIRS Flashcards

1
Q

Inflammation:

A

Protective response (Repair process) intended to eliminate the initial cause of cell injury, removed the damaged tissue, and generate new tissue.

Q

Vascular Phase:

(The vase is opposite)

A

Characterized by changes in small blood vessels
(Arterioles and Venules) at the site of Injury.

It Begins with momentary Vasoconstriction.
Followed Rapidly by Vasodilation. This leads to increased capillary blood flow and heat and redness. Also vascular permability, edema, and swelling, pain and impaired function.

Q

when the body can’t keep up with the response to inflammation…

A

Uncontrolled inflammatory Response with production and release of large quantities of inflammatory mediators. This is SIRS. this can lead to MODS.

Q

MODS: definition

(2 mods failing)

A

Continuation of SIRS.
Usually is a progressive failure of two or more separate organ systems as the organ is not able to maintain hemeostasis.

Q

SIRS - Pathophysiology (inflammation, mediators, systemic/destruction, SIRS/endothelial)

A

Following the Trigger or insult, local Inflammatory Process (Vascular, Cellular, Coagulation Process) and Inflammatory mediators are released into the local area.
Small quantities of local mediators are released into circulation to improve the local response. This is controlled by release of Endogenous antagonist (IL -1 ra). The goal is homeostasis.

If homeostasis is not restored, a significant systemic reaction occurs. The mediator release leads to destruction rather than protection. A consequence of this is the activation of numerous uncontrolled cascades and subsequent loss of circulatory integrity (SIRS).

SIRS cause organ’s endothelial Damage and microvascular Thrombosis due to Coagulation Cascade. This leads to Multiorgan Dysfunction and Failure. (MODS).

Q

Management of SIRS/MODS - first step

A

Initial Medical Care:
History
Physical Examination
Laboratory testing
Imaging Studies

20
Q

Management of SIRS/MODS - second step - just treatment

A

Treatment should be focused and based on possible inciting causes of SIRS ( MI vs. Pneumonia)

21
Q

Management of SIRS/MODS - third step

(Sir, 3rd is your lungs)

A

Supplemental Oxygen
Pt may need Ventilator Support to maximize oxygen delivery. Patients who do not respond to increased oxygen supply have a poor prognosis.

22
Q

Management of SIRS/MODS - 4th step

(Sir, this your 4th drink)

A

Hypotensive should receive intravenous fluids, and, if still hypotensive after adequate resuscitation, Inotropes agents should be administered.

23
Q

Management of SIRS/MODS - 4th step meds

A

Medications:
TNF-and IL-1 receptor antagonists
Antibradykinin
Platelet-activating factor receptor antagonists
Anticoagulants
Low-Dose Steroids.

Studied showed no statistically significant benefits in treatment of SIRS.

24
Q

Management of SIRS/MODS – 4th step meds

A

Medications:
Antibiotics
Studied showed no statistically significant benefits in treatment of SIRS.
Indicated in sepsis or septic shock.

Q

Management of SIRS/MODS - step 5

A

Consultation
Vary on cause of SIRS (Cardiology for MI)
Surgical (Abscess drainage, prosthetic devices)
Intensivists (MODS).
Infectious Disease Expert (HIV, Organ Transplantation, no response to antibiotics).
