General

  • Type: Vasopressors
  • Dosage Forms:
  • Concentration
    • Amount of solution in mL used to dilute 1,000mg of epinephrine
    • eg 1:10,000 = 1,000mg/10,000mL = 0.1mg/mL
  • Common Trade Names: Adrenaline

Adult Dosing

Anaphylaxis

0.3-0.5mg of 1:1,000 IM

  • Consider glucagon 1-5mg IV if pt on B-blockers and not responding to epi

Anaphylactic shock

0.1mg of 1:10,000 slow IV during 5 min, can start infusion of 1-4 mcg/min

Cardiac Arrest

1mg of 1:10,000 IVP

Pediatric Dosing

See critical care quick reference for drug doses by weight.

Special Populations

  • Pregnancy Rating:
  • Lactation:
  • Renal Dosing
    • Adult
    • Pediatric
  • Hepatic Dosing
    • Adult
    • Pediatric

Contraindications

Pressor

Dosing

  • Dose-dependent effects:
  • 1-10 mcg/min - increase HR and SV
  • 10-20 mcg/min - increase SVR

Rate of Titration

  • Q2-5 min

Adverse Effects

  • Tachyarrhythmias
  • Myocardial ischemia
  • ↑Serum lactate
  • Splanchnic ischemia

Notes

  • ↑lactate occurs primarily from ↑glycolysis/glycogenolysis within skeletal muscles not tissue hypoperfusion
  • Use with caution in pts with CAD
    • However clinical trials have not demonstrated worsened outcomes
