Abstract
After defining “short-time hemodialysis” as that given for 3 hours each time and 3 times in 1 week, we studied the effects of such short-time hemodialysis in all patients who desired it.
RENAK A-23 H (2.3m2) was used to dialyze male patients and RENAK A-15 H (1.5m2) for female patients. The short-time hemodialysis was administered at blood flow rates less than 200ml/min. Predialysis hemobiochemical data were compared in the patients who were treated for more than one year, and the causes of the deaths that occurred during the period were studied. Fifty-six of 58 hemodialysis patients desired the short-time hemodialysis, and 54 of them (96.4% of the applicants) received it. The predialytic hemobiochemical examinations after 1 year of short-time hemodialysis showed BUN 79.2±15.6mg/dl, Cr 13.0±3.20mg/dl, K 5.02±0.94mEq/l, Ht 20.6±3.70%, time-averaged BUN 58.9±11.3mg/dl. These were not significantly different (p<0.01) from the cases of customary hemodialysis (5 hours dialysis). The predialytic CTR after 1 year in the short-time hemodialysis group was 55.9±6.30%. This was significantly more (p<0.01) than it was in the cases of customary hemodialysis. Three of the 15 cases of death were directly related to dialysis, but they did not result from the short-time hemodialysis. The 2 cases which could not be shifted to short-time hemodialysis were 1 cases of taking excessive water and 1 cases of blood flow deficiency.
The hemobiochemical data indicated that the short-time hemodialysis may be feasible hemobiochemically, but further studies are needed regarding the significant increasing in CTR.
