Monitor BP, heart rate, ECG, pulmonary capillary wedge pressure (PCWP), cardiac output, CVP, and urinary output continuously during the administration. Report significant changes in vital signs or arrhythmias. Consult physician for parameters for pulse, BP, or ECG changes for adjusting dose or discontinuing medication.
Palpate peripheral pulses and assess appearance of extremities routinely throughout dobutamine administration. Notify physician if quality of pulse deteriorates or if extremities become cold or mottled.
Lab Test Considerations: Monitor potassium concentrations during therapy; may cause hypokalemia.
Monitor electrolytes, BUN, creatinine, and prothrombin time weekly during prolonged therapy.
If overdose occurs, reduction or discontinuation of therapy is the only treatment necessary because of the short duration of dobutamine.
High Alert: IV vasoactive medications are potentially dangerous. Have second practitioner independently check original order, dosage calculations, and infusion pump settings. Do not confuse dobutamine with dopamine. If available as floor stock, store in separate areas.
Correct hypovolemia with volume expanders before initiating dobutamine therapy.
Administer into a large vein and assess administration site frequently. Extravasation may cause pain and inflammation.
Continuous Infusion: Diluent: Vials must be diluted before use. Dilute 250–1000 mg in 250–500 mL of D5W, 0.9% NaCl, 0.45% NaCl, D5/0.45% NaCl, D5/0.9% NaCl, or LR. Admixed infusions stable for 48 hr at room temperature and 7 days if refrigerated. Premixed infusions are already diluted and ready to use.Concentration: 0.25–5 mg/mL.
Rate: Based on patient's weight (see Route/Dosage section). Administer via infusion pump to ensure precise amount delivered. Titrate to patient response (heart rate, presence of ectopic activity, BP, urine output, CVP, PCWP, cardiac index). Dose should be titrated so heart rate does not increase by >10% of baseline.
