Abstract
Abstract Background and Aims The advanced congestive heart failure (CHF), may provoke functional kidney disturbances with insufficient and resistant to conservative therapy water excretion. The treatment of the chronic renal failure (CRF) with active dialysis related to ultrafiltration (UF), may overcome the renal diuretics resistance with diuresis restoration and oedema elimination. The aim of the study was to define the indications for active, discontinued UF in setting of the CHF refractory to drugs, especially in the treatment of oedema. Method We investigated 12 patients, mean age 62,4+/-5,3 years, with incipient renal failure, but advanced congestive heart failure. Seven of them were males and 5 females. The indication for discontinued UF, was the severe expressed heart failure, reduced diuresis and initial renal insufficiency. In all investigated patients, before and after each UF procedure, the serum sodium and potassium, blood urea nitrogen (BUN), creatinin and osmolality were detected. The body weight, abdominal and crural parameters were noted before and after dialysis. Results The recovery was achieved in 10 patients with CHF, but 2 patients out of 12 have not demonstrated satisfactory response to UF. The biochemical features encountered to CHF patients suggest chronic hyponatriemia, hypokalemia and hypovolemia. Proteinuria range 1,2 to 3,6 g/l, was present in 6 patients. The clinical data were performed with oedema formation, reduced diuresis and dispnea. Mean UF rate achieved after several dialysis was 12,4+/- 7,6, lit. Conclusion Chronic heart failure in chronic renal patients, with severe oedemas is an indication for UF therapy, even if the values of BUN and creatinin are not increased. Reduction of the body weight and the extracellular volume, contribute for improved survival in these patients. However the risk of complications is high and not always with successful treatment.
