| Abstract: | Six cases of edema, three due to the nephrotic syndrome, one to congestive heart failure and two to chronic renal failure, are reported in which furosemide was administered in oral doses higher than those usually prescribed (up to 720 mg. a day), in order to obtain a satisfactory diuresis. In one case of severe prerenal failure secondary to cardiogenic shock and in one case of acute tubular necrosis secondary to hypotension at the time of operation, intravenous doses up to 990 and 1400 mg. per day respectively were able to reverse the oliguria. In eight additional patients who were on chronic hemodialysis, furosemide was administered to the amount of 1000 mg. per day orally in divided doses for two weeks, and produced a moderate diuretic response. The use of high doses of furosemide in edema and renal failure resistant to the usual therapeutic measures appears to be safe and effective. |
