When either systolic or diastolic dysfunction of the pumping action of the heart results in compromised CO?
|
Cardiogenic Shock
|
|
Precipitating causes of systolic dysfunction?
|
MI
Cardiomyopathies Blunt cardiac injury Severe HTN |
|
Precipitating causes of diastolic dysfunction?
|
Cardiac tamponade
Cardiomyopathy |
|
Early clinical presentation of cardiogenic shock?
|
Tachycardia
Hypotension Tachypnea Crackles Pale, clammy, cool skin Decreased cap refill Anxiety and agitation may develop as cerebral perfusion is impaired |
|
Collaborative care for cardiogenic shock?
|
Thrombolytic therapy
Angioplasty with stenting Emergency revascularization Valve replacement ****Cardiac cath should be performed as soon as possible after the initial insult **** |
|
Medication to treat cardiogenic shock?
|
Morphine
O2 Dopamine Dobutamine Epinephrine Nitroglycerin |
|
Effects of morphine (cardiogenic shock)?
|
decrease pain
decrease O2 workload and demand |
|
Effects of dopamine (cardiogenic shock)?
|
Increase HR and contractility
Increase blood flow to brain and kidneys |
|
Effects of dobutamine (cardiogenic shock)?
|
Increased contractility of the heart (stronger than dopamine)
|
|
Effects of epinephrine (cardiogenic shock)?
|
Stimulates cardiac system
Dilates bronchioles Peripheral vasodialator (given during cardiac arrest) |
|
Nitroglycerin?
|
Decreases cardiac preload
Vasodialates (take every 5 min, if pain not gone after 3rd dose go to the ER; 2 or 3 doses call MD) |
