Empty Tank
Hallmark is inadequate preload
What is hypovolemic shock?
EBL 1500-2000mL, Tachycardia, Hypotension, Confusion or Irritability
What is Class 3 Hemorrhagic Shock?
Hypersensitivity reaction, inflammatory mediated, laryngeal edema, bronchospasm, hypotension
What is anaphylactic shock?
Mechanism of action of first line therapy for cardiogenic shock
What is beta agonist - dobutamine?
Adjunctive medication for refractory septic shock
What is hydrocortisone (~200-300mg/day)?
Mainstay of treatment of hypovolemia not due to hemorrhage
What is IV crystalloid resuscitation?
First physiological sign in hemorrhagic shock due to increased release of endogenous catecholamines
What is narrowed pulse pressure?
Temporary suppression of reflexes below the level of spinal cord injury
Common causes are tension pneumothorax and cardiac tamponade
What is obstructive/extrinsic cardiogenic shock?
Adjunctive vasopressor for septic shock, not titrated.
What is vasopressin?
20ml/kg crystalloid
What is appropriate initial weight-based bolus?
EBL < 750ml, no vital sign abnormalities, normal mental status
What is class 1 hemorrhagic shock?
Cervical spinal cord injury is most common cause, loss of vascular tone, bradycardia
What is neurogenic shock?
When refractory to inotropic therapy, cardiogenic shock may be treated by these?
What is mechanical circulatory support? (ECMO, balloon pump, Impella)
As the first line agent for septic shock, norepinephrine works on these receptors.
What are alpha-1/2 and beta-1?
This resuscitative fluid has pH 5-5.5
What is normal saline?
EBL > 2000ml, tachycardia, hypotension, obtundation
What is class 4 hemorrhagic shock?
SVR=
(MAP-CVP)/CO x 80
Beta agonist at low doses, predominantly alpha agonist at higher doses.
What is epinephrine?
This lab may be low in septic shock shock prior to volume resuscitation, or high related to mitochondrial dysfunction
What is SVO2?
Resuscitation end points
What are UOP, lactic acid, base deficit?
These medications have virtually no role in the treatment of hemorrhagic shock and have been shown to increase mortality.
What are vasopressors?
Rare cause of neurogenic shock, treatment is placement of an NG tube
What is acute gastric dilation?
Phosphodiesterase inhibitor that decreases afterload, increases inotropy, improves lusitropy
What is milrinone?
Scoring system utilized to identify patients with sepsis
What is SOFA score?
