Methods of intravenous administration

Continuous intravenous infusion (administer using an electronically controlled infusion device)

Central line (ref 1)

  • Add 5ml (200mg) to 45ml infusion fluid (200mg in 50ml) (unlicensed)
  • This contains 4mg (4000micrograms) per ml
  • Rate is adjusted according to response - see under 'dose' 

Peripheral line (ref 1)

  • Add 10ml (400mg) to 240ml infusion fluid (400mg in 250ml)
  • This contains 1.6mg (1600micrograms) per ml
  • To avoid tissue necrosis dopamine is best given via a large vein
  • Rate is adjusted according to response - see under 'Dose'

Dose in adults

Usual dose

  • Initial rate is 2.5 micrograms/kg/minute adjusted according to response - gradually increased in 5 to 10 micrograms/kg/minute increments
  • ACLS guidelines (to treat hypotension especially if associated with symptomatic bradycardia in the immediate post-cardiac arrest care setting): an initial rate of 5 to 10micrograms/kg/min may be used - titrated to effect (ref 2)
  • Increases should be made according to the patient's blood pressure, cardiac output, and urinary output
  • Up to 20 to 50 micrograms/kg/minute may be required in seriously ill patients (ref 3)
  • A reduction in urinary flow without hypotension may indicate a need to reduce the dose (ref 3)
  • When gradually stopping dopamine, it is advised that care be taken to avoid undue hypotension associated with very low dosage levels, where vasodilation could predominate (ref 3)

Monitoring

  • Monitor blood pressure, ECG and cardiac and urinary output 
  • When used in patients with a history of occlusive vascular disease, closely monitor for any changes in colour or temperature of the skin of the extremities

Further information

  • Low-dose dopamine has no role in reducing renal dysfunction
  • If extravasation occurs, dopamine may cause necrosis and sloughing of surrounding tissue. To prevent sloughing and necrosis, the area should be infiltrated as soon as possible with 10 to 15ml of a Sodium chloride 0.9% solution containing 5 to 10mg phentolamine

Storage

  • Store below 250C
