title: Home intravenous dobutamine therapy in patients awaiting heart transplantation.
abstract: Lack of donor availability has heightened our awareness of the need for suitable long-term management of heart failure in patients awaiting heart transplantation. Frequently patients become dependent on intravenous inotropic agents despite attempts to discontinue these agents. This can lead to prolonged hospitalizations, separation anxiety and depression in families, high hospitalization costs, and poor quality of life. Between June 1987 and April 1988 three patients awaiting heart transplantation at the University of Cincinnati Hospital were sent home while receiving constant intravenous infusion of dobutamine. All three patients had had prolonged hospitalizations and were unable to be weaned from dobutamine without clinical compromise. The patients were New York Heart Association functional class III to IV, had cardiac indices between 1.5 to 2.13 L/min/m2, cardiac output less than 4.0 L/min, pulmonary capillary wedge pressures 17 to 27 mm Hg, and left ventricular ejection fraction less than 20% in two of the patients (idiopathic cardiomyopathy), and 30% in the third patient who was awaiting retransplantation (refractory repeated acute rejections). Dobutamine was infused by means of a constant-rate portable cassette pump at 3.17 micrograms/kg/min in patient 1, 10 micrograms/kg/min in patient 2, and 5 micrograms/kg/min in patient 3. A critical care home health nursing agency was used for follow-up home care. All three patients had central lines placed before discharge from the hospital. Each patient was instructed in proper care of the central line and infusion pump and was able to demonstrate accurate technique before being discharged home. Complications were minimal and were related to central line placement. No patient required rehospitalization for complications. No wound infections were reported.(ABSTRACT TRUNCATED AT 250 WORDS)
