crystalloids

Last reviewed 01/2018

Crystalloids include:

  • isotonic solutions:
    • normal saline 0.9%
    • Hartmann's - the same as lactated Ringer's
    • dextrose 4% saline 0.18%
    • dextrose 5%

  • non-isotonic solutions:
    • dextrose 15%, 20%, 50%
    • sodium bicarbonate 4.2%, 8.4%
    • mannitol 10%, 20%

It is important to note that the word isotonic only refers to the fact that red cells do not explode; dextrose is rapidly absorbed and metabolised leaving a hypotonic solution - which behaves like water.
