Spanish to English Medical Medical (general) Dialysis treatment

This abbreviation shows up in a report of a patient undergoing hemodialysis in a hospital; the patient also received a transfusion of red blood cells during the procedure. The description reads:

"Pte. grave en Ventilacion Mecanica sin sedacion c/ buena tolerancia, hemodinamicamente estable, c/ *DUA* (Dobutamina). Durante terapia con tendencia a la hipertension sistolica ... etc.

I don't find DUA in the KudoZ glossaries or in the Tremedica site, and I don't find this abbreviation in connection with Dobutamina, so I don't think it's an abbreviation for this drug.

What is this abbreviation in this context? That is, what is it in Spanish and how would we say it in English?
