Fluid

Restriction may be needed to prevent excessive fluid retention, depending on urine output. Impossible if salt intake high. Must count foods with a high fluid content (e.g. soup, ice cream, custard, gravy, jelly) in allowance. Difficult; aim to give practical tips: using smaller cups, sucking ice-cubes

Pre-dialysis

  • Ensure adequate fluid intake (2-2.5L per day)
  • May require restriction when nearing ESRF

Haemodialysis

  • Varies depending on residual renal function
  • Usually 500mls + PDUO
  • Intradialytic weight gains of >2kg indicate excessive fluid intakes

Peritoneal Dialysis

  • Varies depending on residual renal function and ultra filtration
  • Tends to be less restricted than in haemodialysis
