Hypertonic
A Hypertonic solution contains a higher concentration of electrolytes than that found in body cells. If such a solution is allowed to enter the blood stream, the osmotic pressure difference between the blood and the cells will cause water to flow out of the cells, which will then shrink. This may cause serious harm, or even be fatal. Consequently, it is essential when blood transfusions are given, or blood replacement products are used, that the electrolyte concentration in the material to be given to a patient matches that of the body.
See also hypotonic.
