Dobutamine Infusion Rates by Patient Weight

For dobutamine infusions in pediatric and adult patients, use the FDA-approved dosing tables that provide weight-based infusion rates from 2.5 to 20 µg/kg/min across patient weights of 10-80 kg, with standard concentrations of 500,1,000, or 2,000 µg/mL 1.

Standard Dosing Range

The typical therapeutic range is 2-20 µg/kg/min, though rates up to 40 µg/kg/min have occasionally been required 1. Start infusions at 0.5-1.0 µg/kg/min and titrate every few minutes based on hemodynamic response 1.

Weight-Based Infusion Tables

For 1,000 µg/mL Concentration (Most Common)

Infusion rates in mL/hr:

Dose (µg/kg/min) 10 kg 20 kg 30 kg 40 kg 50 kg 60 kg 70 kg 80 kg
2.5 1.5 3 4.5 6 7.5 9 10.5 12
5 3 6 9 12 15 18 21 24
7.5 4.5 9 13.5 18 22.5 27 31.5 36
10 6 12 18 24 30 36 42 48
12.5 7.5 15 22.5 30 37.5 45 52.5 60

For 500 µg/mL Concentration

Infusion rates in mL/hr (double the 1,000 µg/mL rates):

Dose (µg/kg/min) 10 kg 20 kg 30 kg 40 kg 50 kg 60 kg 70 kg 80 kg

For 2,000 µg/mL Concentration

Infusion rates in mL/hr (half the 1,000 µg/mL rates):

Dose (µg/kg/min) 10 kg 20 kg 30 kg 40 kg 50 kg 60 kg 70 kg 80 kg
2.5 0.7 1.5 2 3 4 4.5 5 6

Clinical Guidance from Guidelines

Dobutamine is indicated for myocardial dysfunction with decreased contractility 2. The AHA Pediatric Advanced Life Support guidelines specify that dobutamine increases myocardial contractility and decreases peripheral vascular resistance through β1- and β2-adrenergic receptor effects 2.

Titration Strategy

  • Start low: 0.5-1.0 µg/kg/min
  • Titrate every few minutes based on:
    • Systemic blood pressure
    • Heart rate
    • Urine output
    • Cardiac output (when available)
    • Central venous pressure/pulmonary capillary wedge pressure
  • Optimal range: Usually 2-20 µg/kg/min, though individual response varies significantly 1

Critical Safety Points

Infuse through a secure IV line to prevent local ischemia and tissue ulceration 2. Potential adverse effects include tachycardia, arrhythmias (atrial and ventricular), hypertension, hyperglycemia, increased lactate, and hypokalemia 2.

Do not mix with sodium bicarbonate or other strongly alkaline solutions 1. Use prepared solutions within 24 hours 1.

Hemodynamic Effects by Dose

Research demonstrates dose-dependent effects:

  • 2.5 µg/kg/min: Decreases afterload and filling pressures 3
  • 5-7.5 µg/kg/min: Increases stroke index and cardiac index; optimal hemodynamic benefit in many patients 4, 3
  • 10-15 µg/kg/min: Further increases cardiac index primarily through tachycardia rather than stroke volume 3
  • >7.5 µg/kg/min: Risk of increased ventricular ectopy 4

In prolonged infusions (>2 hours), the initial tachycardia becomes transient, with sustained increases in stroke volume and improved mesenteric/renal blood flow 5.
