salty; of the nature of a salt.

saline cathartic
see saline cathartic.
saline drench
an orally administered preparation of electrolytes in water used in racehorses but more particularly in endurance and event horses in which heavy electrolyte losses in sweat are likely. A variety of formulations is used but all contain sodium, potassium, calcium and magnesium ions; some also contain glucose.
saline solution
a solution of salt (sodium chloride) in purified water. Physiological saline solution is a 0.9% solution of sodium chloride and water and is isotonic, i.e. of the same osmotic pressure as blood serum.
saline water poisoning
see sodium chloride poisoning.
saline waters
waters from surface running mineral springs, water obtained from natural underground storages in artesian and subartesian bores.


1. a liquid preparation of one or more soluble chemical substances usually dissolved in water.
2. the process of dissolving or disrupting.

aqueous solution
one in which water is used as the solvent.
buffer solution
one that resists appreciable change in its hydrogen ion concentration (pH) when acid or alkali is added to it.
colloid solution, colloidal solution
a preparation consisting of minute particles of matter suspended in a solvent.
hyperbaric solution
one having a greater specific gravity than a standard of reference.
hypertonic solution
one having an osmotic pressure greater than that of a standard of reference.
hypobaric solution
one having a specific gravity less than that of a standard of reference.
hypotonic solution
one having an osmotic pressure less than that of a standard of reference.
iodine solution
a transparent, reddish brown liquid, each 100 ml of which contains 1.8 to 2.2 g of iodine and 2.1 to 2.6 g of sodium iodide; a local anti-infective.
iodine solution (strong)
Lugol's solution.
isobaric solution
a solution having the same specific gravity as a standard of reference.
isotonic solution
one having an osmotic pressure the same as that of a standard of reference.
molar solution
a solution each liter of which contains 1 mole of the dissolved substance; designated 1 M. The concentration of other solutions may be expressed in relation to that of molar solutions as tenth-molar (0.1 M), etc.
normal solution
a solution each liter of which contains 1 chemical equivalent of the dissolved substance; designated 1 N.
ophthalmic solution
a sterile solution, free from foreign particles, for instillation into the eye.
physiological saline solution, physiological salt solution, physiological sodium chloride solution
an aqueous solution of sodium chloride and other components, having an osmotic pressure identical to that of blood serum.
priming solution
the fluid used to fill tubing and the reservoir of a cardiac bypass unit before use.
saline solution
a solution of sodium chloride, or common salt, in purified water.
saturated solution
a solution in which the solvent has taken up all of the dissolved substance that it can hold in solution.
sclerosing solution
one containing an irritant substance that will cause obliteration of a space, such as the lumen of a varicose vein or the cavity of a hernial sac.
standard solution
one containing a fixed amount of solute.
supersaturated solution
one containing a greater quantity of the solute than the solvent can hold in solution under ordinary conditions.
volumetric solution
one that contains a specific quantity of solvent per stated unit of volume.

Patient discussion about saline solution

Q. Do any of you with FM have silicone breast implants, or have you ever had them? How about saline? My silicone implants expired on the surgeon's shelf before they went in my body. Both implants ruptured and disintegrated within 5 years of implantation. I was diagnosed with FM shortly after 2 surgeries to remove silicone goo. Just wondering if anyone else has made the connection. Thank you!

A. As far as I know several studies failed to prove there is a connection between rupture of breast implants and fibromyalgia, as did the FDA conclude. Indeed I heard about one study that found this connection, but it seemed like a very problematic one.
