Shock - Answer: Lack of oxygen to the cells
Hypovolemic Shock - Answer: Lack of volume
ex: hemorrhage, burns
Distributive Shock - Answer: Maldistribution of blood (pooled in extremities)
Decreased preload
ex: neurogenic shock
Cardiogenic Shock - Answer: Inadequate cardiac output
ex: blunt cardiac trauma
Obstructive Shock - Answer: Inability of blood to enter or exit heart properly
ex: tamponade, tension pneumothorax
Systemic Inflammatory Response Syndrome (SIRS) - Answer: Severe tissue trauma
activates an inflammatory response leading to vasodilation, capillary permeability, and
coagulation
Early (Compensated) Shock - Answer: Normal BP
Weak, thready pulse
Deep and rapid RR
Normal lactic levels
Anxious

Trauma Triad of Death - Answer: Hypothermia
Acidosis
Coagulopathies
Effects of Acidosis - Answer: Increased ICP
Exacerbates coagulopathies
Depressed myocardial contractility
DIC - Answer: Excessive clotting > all clotting factors used > no more clotting > excessive
bleeding

3
, Universal Donor of RBC and Plasma - Answer: Universal donor of RBC: O negative
Universal donor of Plasma: AB negative
Cryoprecipitate - Answer: Concentrate of coagulation factors obtained from fresh frozen
plasma
Increases fibrinogen in the bloodstream
Blood Transfusion in Peds - Answer: One unit of blood is 10ml/kg
Complications of MTP - Answer: Hypothermia - warm all fluids and blood
Hypocalcemia - replace calcium
Acidosis - sodium bicarb
TRALI - stop transfusion, supplemental oxygen
Transfusion-Related Acute Lung Injury (TRALI) - Answer: Pulmonary edema due to rapid
blood administration
MTP Protocol - Answer: 1 : 1 : 1
RBC : Plasma : Platelet
Blood Loss Grades - Answer: I - Loss of 15% with normal BP
II - Loss of 15-30% with normal BP
III - Loss: of 31-40% with lowered BP
IV - Loss > 40% with hemodynamic instability
Permissive Hypotension - Answer: Maintaining BP as low as 70/40 so allow for clotting.
