Click on the blue circled arrows just down to the right; then on the Go button below that to show the effects of each fluid. Click on the blue arrows to work through all the options.
UPDATE 2013 - Fluids with high chloride content such as 0.9% NaCl (150mmol/l) have been associated with poor outcomes when given in large volumes. Alternatives such as Hartmann's Solution contain Lactate or Acetate, which are converted in the liver to bicarbonate, and lower chloride. These are probably better for resuscitation. Their effects on fluid compartments are identical to 0.9% NaCl.
When you've finished this section, we recommend you look at our Fluid Therapy Prescribing Guide for clinicians (or bit.ly/fluidtherapy; some background to this guidance), before tackling the first case ... unless you want to go back and check something on the tabs above. That's not such a bad idea either.
