Flashcards do conjunto (19)
- 1What is circulatory shock?acute failure of circulation to vital organs
- 2What is anaphylactic shock?acute severe allergic response to certrain allergens
- 3What does the allergen activate in an anaphylactic shock?cells to release massive amounts of histamine and mediators (prostaglandins and bradykinins)
- 4What do histamines and mediators cause in anaphylactic shock?Increase capillary permeability and leakage, increased mucous membrane secretion, marked vasodilation and severe bronchoconstriction
- 5what does the increased capillary leakage mean for anaphylactic shock?less venous return of vascular fluid to heart so a reduction in pulse pressure and cardiac output to vital organs
- 6What does vasodilation due to anaphylactic shockreduces perfusion of vital organs and systolic and mean arterial pressures fall
- 7What is given first to anaphylactic pt to reverse circulatory and respiratory problemsHigh systematic dose of epinephrine
- 8What is cardiogenic shock caused bysignificant loss of left ventricular muscle contractile function after an event like AMI
- 9What happens to cardiac output and arterial resistancedecreases; increases
- 10What is used to help support circulation in cardiogenic shock?NE, DA and Dobutamine, to help stimulate functional beta receptors
- 11What is neurogenic shock?acute loss of neural support of the circulation due to spinal cardiac injury or brain damage to vasomotor center
- 12What decreases during neurogenic shock?Cardiac output and arterial pressure and vascular resistance
- 13What is given neurogenic shock patientsNE, DA, or phenylephrine to support of circulation
- 14What is septic shock called? What is it?Blood poisoning; widely disseminated bacterial infection borne by the blood
- 15What is a normal bacteremia in septic shock?Gm- bacteria, release of endotoxin
- 16What happens with early warm phase? How is it treated?Pressure falls due to vasodilation; NE or vasodilator (α1 stimulating) dose of DA to reverse vasodilation
- 17What happens with late cold phase? How is it treated?Vascular resistance return to high levels, arterial pressure is low/ cardiac output is low; only give DA cardiac β1 stimulating dose without α stimulation
- 18What is used to help mesenteric and renal circulationlow dose of DA can selectivity improve blood to regions
