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 (4000 micrograms) 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
- In more severe cases, administration may be initiated at a rate of 5 micrograms/kg/minute, and increased gradually in 5 to 10 micrograms/kg/minute increments up to 20 to 50 micrograms/kg/minute as needed
- Increases should be made according to the patient's blood pressure, cardiac output, and urinary output
- A reduction in urinary flow without hypotension may indicate a need to reduce the dose
- Dopamine should be withdrawn gradually to avoid unnecessary hypotension

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
