Hartmann's Solution

Jump to: navigation, search

Hartmann's solution or Compound Sodium Lactate is a solution that is isotonic with blood and intended for intravenous administration.

Hartmann's solution is abbreviated as "CSL". It is very similar--though not identical to--Lactated Ringer's solution, the ionic concentrations of which differ.


One litre of Hartmann's Solution contains:

Generally, the sodium, chloride, potassium and lactate come from NaCl (sodium chloride), NaC3H5O3 (sodium lactate), CaCl2 (calcium chloride), and KCl (potassium chloride).


Hartmann's solution is said to be contraindicated in patients with diabetes mellitus, as one of the isomers of lactate is gluconeogenic[1].
