Dopamine (Intropin) Notes

Classification

• Therapeutic: inotropics, vasopressors
  
• Pharmacologic: adrenergics 
  

Dosage 

• Dopaminergic (renal vasodilation) effects
• 1–5 mcg/kg/min stimulate dopaminergic receptors, producing renal vasodilation. 
• Beta-adrenergic (cardiac stimulation) effects
  
• 5–10 mcg/kg/min) stimulate dopaminergic and beta1-adrenergic receptors, producing cardiac stimulation and renal vasodilation.
• Alpha-adrenergic (increased peripheral vascular resistance) effects
  

• Doses greater than 10 mcg/kg/min stimulate alpha-adrenergic receptors and may cause renal vasoconstriction.

  
  

  Review

  In this song, I use basketball players as a metaphor for vasopressors and inotropes used in critical care medicine. Their jersey numbers reflect their maximum dose. Their position reflects how they should be administered, central vs. peripheral. The song is filled with many homonyms, so that each time you listen you may discover something new. On the right side of the screen, I reveal these meanings as the song progresses
