  1. Outline the various vasopressors available
  2. Discuss the clinical situations when to use specific vasopressors


  • Dopamine – Pressor looking for an indication
  • Phenylephrine – Alpha agonist; Vasoconstriction; Can decrease CO
  • Epinephrine – Alpha/Beta agonist; Lower doses Beta > Alpha; Higher doses Alpha > Beta; Can cause arrhythmias and type B lactic acidosis; Consider 1st line in status asthmaticus and anaphylactic shock
  • Norepinephrine – Alpha/Beta agonist; Increases arterial/venous tone and can increase pulmonary vascular resistance; Consider 1st line in septic shock
  • Vasopressin – V1 receptor agonist; Less likely to increase pulmonary vascular resistance compared to other vasopressors
  • Angiotensin II – Very expensive; Not readily available; Studied in sepsis and distributive shock
