works by increasing the strength of myocardial contraction which increases cardiac output. Can also suppress the electrical conductivity of the heart

titers, blood dyscrasias (stabilizes membranes
Anaphylactic
severe allergic reaction (usual allergens include PCN, nuts, shellfish).
cardiogenic shock
failure of the heart to pump blood to vital organs. Usually caused by left heart failure, MI, PE, dysrhythmia, myocardial infection
hypovolemic shock
severe loss of blood volume. Usually due to massive hemorrhage, burns, severe dehydration (excessive diuresis, N&V, diarrhea)
neurogenic shock
vasodilation due to overstimulation of the parasympathetic nervous system or under stimulation of the sympathetic nervous system. This occurs with trauma to the spinal cord/brain stem, severe emotional distress/pain, CNS depressants
septic shock
multiorgan dysfunction due to infection (within the bloodstream). Leads to ARDS/DIC. Caused by an “inflammatory storm” response to infection
Symptoms of shock include
CNS
cardiovascular
skin
respiratory
metabolic
CNS shock symptoms
restlessness, anxiety, confusion (early) followed by lethargy and LOC (late
cardiovascular shock symptoms
low BP and cardiac output, increased HR, thready pulse
skin shock symptoms
pale, clammy, cool
respiratory shock symptoms
rapid breathing followed by shallow breathing
metabolic shock symptoms
decreased body temperature, thirst, low urine output-acidosis
treatments for shock
fluid replacement
treating hyportension
anaphylaxis
fluid replacement treatment for shock
blood products, colloids (albumin-plasma expanders), and crystalloids (IVF)
treating hypotension regarding shock
vasoconstrictors (vasopressors) and adrenergic agonists/inotropic
vasoconstrictors
these drugs activate the sympathetic nervous system (dopamine, epinephrine, norepinephrine, digoxin, dobutamine)
anyphylactic treatment of shock
in addition to the above, antihistamines, albuterol, and systemic corticosteroids may also be used.
Macrocytic-normochromic size of RBCs
