OBJECTIVES: To assess the value of treatment with continuous intravenous infusion of furosemide (F) in patients with refractory congestive heart failure. DESIGN: Open uncontrolled dose-response study. SUBJECTS: Patients with congestive heart failure (those with New York Heart Association (NYHA) classes III and IV with an assessed amount of oedema of more than 5 kg and diuretic resistance were included [n = 10]). Diuretic resistance was defined as: failure to lose weight and/or inappropriate urinary sodium excretion (50 mmol 24 h-1) despite bed rest for a period of 2-3 days, salt and water restriction, orally and intravenously administered furosemide in a dose of 250 mg day-1, digoxin, and when possible an ACE inhibitor. Included patients were treated with continuous F infusion at a delivery rate of 20 mg-1 over 24 h. The infusion rate was gradually heightened up to a maximum dose of 160 mg h-1. MAIN OUTCOME MEASURES: Daily physical examination, history of side-effects, determination of serum electrolytes and 24-h electrolyte excretion during treatment with furosemide. RESULTS: Weight loss (mean +/- SD; 12.5 +/- 5 kg) and relief of symptoms was achieved in all patients. Mean (+/- SD) 24-h sodium output rose from 19 +/- 16 mmol 24 h-1 (n = 10) on oral therapy with 250 mg F to 137 +/- 85 mmol 24 h-1 (n = 8) during 80 mg h-1 and to 268 +/- 124 mmol 24 h-1 (n = 3) on the maximal dose of 160 mg h-1. CONCLUSION: Continuous infusion of F under careful monitoring of the patient is a safe, controllable and efficient treatment in patients with severe congestive heart failure and diuretic resistance.
