Because of the relatively poor mass transport of small solute compared to hemodialysis, peritoneal dialysis takes longer to achieve a given degree of control of the concentration of low molecular weight solutes like urea. Peritoneal clearance#y may be increased by 30 percent during acute peritoneal dialysis with the addition of vasoactive substances, particulary in patients with systemic vasc lar disease, thereby could reduce the time comm tment necessary for aeute perltoneal dialysis. Here is no need to augment peritoneal clearances with the addition of vasoactive substances in most of end stage renal failure patients on CAPD.
With the CAPD, augmented peritoneal clearances can be required for limited period under such circumstances as decreased effective peritoneal surface caused by frequent episodes of peritonitis or increased catabolic rate.
