Types of Hemodialysis

PERITONEAL DIALYSIS

 Continuous ambulatory peritoneal dialysis (CAPD)
  • Manual PD is termed continuous ambulatory peritoneal dialysis (CAPD)
  • standard CAPD regimen consisting of 4-5, 2-L exchanges/day (Figure 1). The procedure involves the infusion of the solution (approximately 10 min), a dwell period (3-6 hours) and drainage of the dialysate (10 - 20 min)
  • Due to variation in patient size and body composition, they might not be able to achieve enough solute clearance per day with the standard CAPD prescription. They may thus require more, frequent exchanges or larger infusion volumes
  • The simplicity of CAPD, its low cost, and the associated freedom from machines made CAPD a very popular form of chronic PD. In addition, CAPD can maintain a steady physiological state, control fluid volume and blood pressure in most patients 
Intermittent peritoneal dialysis (IPD)
  • IPD is an automated peritoneal dialysis
  • generally consists of frequent, short cycles performed over 8 - 10 hours per session, three times weekly
  • If IPD is practiced on a nightly basis only, it is referred to as nocturnal IPD (NIPD)
  • NIPD is mostly reserved for patients with high solute transport and limited ultrafiltration, since the short cycles of NIPD can achieve better ultrafiltration than the longer cycles of CAPD or CCPD. The total volume of dialysis fluid exchanged per treatment ranges between 8 L and 12 L
