Flashcards in Pericarditis & Cardiac Tamponade Deck (17):
1

pericarditis is

inflammation of pericardium

2

pericardium is the

membrane around the heart

3

pericarditis is due to

infection or injury

4

_________ will accumulate between membrane & wall of heart

exudate

5

what type of exudate will accumulate

-fibrinous exudate
-Fluid (serous) exudate

6

Inflammation causes _________

increased capillary permeability which causes exudate in pericardial space

7

which exudate accumulation is more problematic?

-fibrinous because it is fixed, constrictive, restricts filling & restricts cardiac function
-serous exudate can be displaced

8

constrictive pericarditis =

fibrinous scar tissue

9

Mnfts of pericarditis

(triad - 3 Specific)
-Chest pain, exaggerated by respiration & movement
-pericardial rub (friction rub) (audible)
-serial ECG changes

10

Diagnosing pericarditis

-Mnfts
-ECG
-x-ray
-echo

11

treatment of pericarditis

-based on cause (infection vs injury) (bacterial vs viral)
-anti-inflammatory drugs
-Antibiotics (if due to bacterial infection)

12

pericarditis may lead to

cardiac tamponade

13

cardiac tamponade is

external compression of the heart

14

cardiac tamponade is due to

accumulation of fluid, pus, air in pericardial space

15

cardiac tamponade can restrict

filling & emptying of the heart (Can be life threatening)

16

Manifestations of cardiac tamponade

-heart not able to fill, not able to empty
-decrease in cardiac output
-decrease in arterial pressure
-temporary tachycardia (whenever CO decreases, SNS kicks in increase HR) (compensation then de-compensation thats why temporary)

17

Treatment of cardiac tamponade

STAT pericardiocentesis (removal of fluid)
