PD SOLUTIONS

Question 1

What are the 3 components of a PD solution?

Answer 1

1. OSMOTIC AGENT (to induce ultrafiltration)
2. BUFFER (to correct uremic metabolic acidosis)
3. ELECTROLYTES (to optimize diffusive removal of solutes)

Question 2

What are the 4 components of the most widely used PD solution?

Answer 2

1. dextrose (as an osmotic agent)
   • 1.5%, 2.5%, or 4.25%
2. lactate (as the buffer)
   • 40 mEq/L
3. calcium
   • 2.5 mEq/L
4. pH of 5.4
