Peritoneal dialysis was performed in 16 renal-failure patients to study the
necessity of complete drainage during the outflow period. Comparison between
complete drainage (CD) and the accelerated inflow and limited outflow (AILO)
showed no difference of drainage volume despite the accelerated outflow during
the AILO period. It is postulated that the higher level of dialysate in the
fluid line during the AILO period resulted in a relative increase availability
of the outflow through the catheter perforations. In the CD period the
peritoneal clearances of urea, creatinine and inulin were lower because of
inefficient transport of these solutes during the outflow phase. The authors
concluded that complete drainage is not necessary in intermittent peritoneal
dialysis.
KEY WORDS: Intermittent peritoneal dialysis; Inflow rate; Outflow rate.
