choice of dialysate

Last reviewed 01/2018

The main variables in dialysate composition are:

• sodium concentration - 130 to 140 mM
• glucose concentration - 1.5 to 6%; 1.5% is approximately isotonic with plasma
• potassium - if required

Guidelines:

• both blood pressure and volume are normal or low:
• 140 mM sodium and 1.5% glucose
• blood pressure or volume are raised:
• 135 mM sodium and 3% glucose
• both blood pressure and volume are raised:
• 130 mM sodium and 6% glucose

If the metabolic consequences of glucose overload become problematic, substitute another osmotically active solute and/or amend diet.
