CIRCULATION assesment in Rapid Primary Survey Flashcards
Definition of Shock
inadequate organ and tissue perfusion with oxygenated blood (brain, kidney, extremities)
Name the 4 main types of shock
Hypovolemic
Cardiogenic
Distributive (vasodilation)
Obstructive
Name the 4 causes of Hypovolemic shock
Hemorrhage (external and internal) Severe burns High output fistulas Dehydration (diarrhea, DKA)
Name the 5 causes of Cardiogenic shock
Myocardial ischemia Dysrhythmias CHF Cardiomyopathies Cardiac valve problems
Name the 3 causes of Distributive shock
Septic
Anaphylactic
Neurogenic (spinal cord
injury)
Name the 5 causes of Obstructive shock
Cardiac tamponade Tension pneumothorax PE Aortic stenosis Constrictive pericarditis
early signs of shock are:
tachypnea, tachycardia, narrow pulse pressure, reduced capillary refill, cool extremities, and
reduced central venous pressure
late signs of shock are:
hypotension and altered mental status, reduced urine output
Explain the 3:1 Rule on the hypovolemic shock
Since only 30% of infused isotonic
crystalloids remains in intravascular space,
you must give 3x estimated blood loss
for the Management of Hemorrhagic Shock you should start ___ LARGE BORE (___-___G) IVs in the ____/_____ vein of each arm
start TWO LARGE BORE (14-16G) IVs in the brachial/cephalic vein of each arm
Management of Hemorrhagic Shock .
run ___-___ L bolus of IV ____/_____ (warmed, if possible)
run 1-2 L bolus of IV Normal Saline/Ringer’s Lactate (warmed, if possible)
• if continual bleeding or no response to crystalloids, consider:
pRBC transfusion, ideally crossmatched.
If crossmatched blood is unavailable, consider O- for women of childbearing age and O+ for men.
Use
in early bleeding…
FFP, platelets or tranexamic acid
consider common sites of internal bleeding (____, ____, ____, ____) where surgical
intervention may be necessary
(abdomen, chest, pelvis, long bones)
explain the : 4:2:1 rule on fluid resuscitation
- Maintenance: 4:2:1 rule
- 0-10 kg: 4 cc/kg/h
- 10-20 kg: 2 cc/kg/h
- Remaining weight: 1 cc/kg/h
