Dobutamine Dosing Chart for 10-80 kg Patients

The standard dobutamine infusion dosing range is 2-20 µg/kg/min, with a starting dose of 0.5-1.0 µg/kg/min titrated upward based on clinical response 1.

Standard Dosing Protocol

Initial dose: Start at 0.5-1.0 µg/kg/min
Titration: Increase at intervals of a few minutes based on patient response
Typical therapeutic range: 2-20 µg/kg/min
Maximum dose: Up to 40 µg/kg/min in rare circumstances 1

Weight-Based Infusion Rate Chart

The following table provides infusion rates (mL/h) for a 1,000 µg/mL concentration across different patient weights and dosing targets 1:

Dose (µg/kg/min) 10 kg 20 kg 30 kg 40 kg 50 kg 60 kg 70 kg 80 kg
0.5 0.3 0.6 0.9 1.2 1.5 1.8 2.1 2.4
1 0.6 1.2 1.8 2.4 3.0 3.6 4.2 4.8
2.5 1.5 3.0 4.5 6.0 7.5 9.0 10.5 12.0
5 3.0 6.0 9.0 12.0 15.0 18.0 21.0 24.0
7.5 4.5 9.0 13.5 18.0 22.5 27.0 31.5 36.0
10 6.0 12.0 18.0 24.0 30.0 36.0 42.0 48.0
12.5 7.5 15.0 22.5 30.0 37.5 45.0 52.5 60.0
15 9.0 18.0 27.0 36.0 45.0 54.0 63.0 72.0
20 12.0 24.0 36.0 48.0 60.0 72.0 84.0 96.0

Clinical Application Guidelines

Monitoring Requirements

  • Continuous hemodynamic monitoring is essential when using dobutamine 2
  • Monitor: systemic blood pressure, heart rate, urine flow, frequency of ectopic activity, and cardiac output when possible 1
  • Assess for dose-limiting side effects: excessive tachycardia, arrhythmias, or ischemia 3

Titration Strategy

  • Begin at 0.5-1.0 µg/kg/min
  • Increase dose every few minutes based on clinical response
  • Most patients respond optimally between 2-20 µg/kg/min 1
  • Doses >20 µg/kg/min rarely needed and increase risk of complications 4

Context-Specific Dosing

For cardiogenic shock/heart failure:

  • Start at 2-20 µg/kg/min and titrate to effect 2, 4
  • May be combined with vasodilators if afterload reduction needed 5

For stress echocardiography (diagnostic):

  • Start at 5-10 µg/kg/min 6, 7
  • Increase in 3-5 minute stages up to 40-50 µg/kg/min to achieve target heart rate 6, 7
  • For viability assessment: use lower doses (2.5 µg/kg/min starting, 20 µg/kg/min maximum) with longer 5-minute steps 7

Pediatric considerations:

  • Same weight-based dosing applies 8
  • For stress testing in children: 10-50 µg/kg/min in 3-5 minute stages 6

Critical Safety Points

  • Do not mix with sodium bicarbonate or strongly alkaline solutions 1
  • Dilute to at least 50 mL in compatible IV solution 1
  • Use within 24 hours of preparation 1
  • Have esmolol (0.5 mg/kg) available to reverse adverse effects during stress testing 6
  • Extravascular administration causes severe skin injury; phentolamine may be used for extravasation 4
  • May cause tachyarrhythmias, hypertension, and increased myocardial oxygen consumption 8, 4
