DictionarySeesolutionEncyclopediaSeenormalnormal saline solution
normal [nor´mal] agreeing with the regular and established type. When said of a solution, it denotes one containing one chemical equivalent of solute per liter of solution; e.g., a 0.5 normal (0.5 N) solution has a concentration of 0.5 Eq/l. The use of standard units (Eq/l) is now preferred.normal saline solution (normal salt solution) physiologic salt solution.solutionS11-870480 (so-loo'shon) [L. solvere, to loosen, dissolve] 1. A liquid containing a dissolved substance.2. The process by which a solid is homogeneously mixed with a liquid, solid, or gas so that the dissolved substances cannot be distinguished from the resultant fluid.3. A mixture formed by dissolution of substances.The liquid in which the substances are dissolved is called the solvent and the substance dissolved, the solute. aqueous solutionA solution containing water as the solvent.balanced solution1. Isotonic solution.2. A solution whose concentrations are matched physiologically to the part of the body in which it will be infused or used for irrigation. See: isotonic solutionBenedict solution See: Benedict solutionbuffer solutionA solution of a weak acid and its salt, e.g., carbonic acid, sodium bicarbonate, important in maintaining a constant pH, esp. of the blood.Burow solution See: Burow solutioncitrate solutionA solution, usually combined with dextrose and other agents, to prevent blood clotting. It allows whole blood to be stored until it is needed for transfusion. cobra venom solutionA sterile physiological salt solution containing minute quantities of cobra venom.colloidal solutionA solution in which the solute is suspended, not dissolved, such as gelatin or albumin.Dakin solution See: Dakin solutionFehling solution See: Fehling solutionHartmann solution See: Hartmann solutionheparin lock flush solutionA solution of unfractionated heparins formerly used to keep intravenous infusion devices from clotting. Heparin flushes are now seldom used because they are more expensive than saline flushes and pose a risk of heparin-related thrombocytopenia, a potentially life-threatening allergy. histidine-tryptophan-ketoglutarate solution Abbreviation: HTK solution A preservative to protect a harvested organ before its transplantation into a donor. It is typically infused into the donor organ before the organ is removed from the body and then used to bathe the organ while it is kept in storage at 4° C before implantation into the recipient. hyperbaric solutionA solution with a specific gravity and an osmotic pressure greater than one, or greater than the solution to which it is being compared. It is important in injecting medicines or anesthetic agents into the spinal fluid in the spinal canal. See: hyperbaric chamberhypertonic solutionA solution having a greater osmotic pressure than that of cells or body fluids; a solution that draws water out of cells, thus inducing plasmolysis.hypotonic solutionA solution having an osmotic pressure less than that of cells or body fluids; a solution that will cause water to enter cells, thus inducing swelling and possibly lysis.iodine solutionA solution of iodine or potassium iodine used as a source of iodine.irrigating solutionAny fluid used to rinse an organ or body cavity. SEE: irrigation See: irrigation.isobaric solutionA solution with a specific gravity equal to one or equal to the solution with which it is being compared. See: hyperbaric solutionisohydric solutionA solution having the same hydrogen ion concentration or pH as another.isosmotic solutionA solution with the same osmotic pressure as the solution with which it is being compared.isotonic solutionA solution that has a concentration of electrolytes, nonelectrolytes, or both that will exert osmotic pressure equivalent to that of the solution with which it is being compared. Either 0.16 molar sodium chloride solution (approx. 0.95% salt in water) or 0.3 molar nonelectrolyte solution is approx. isotonic with human red blood cells. Synonym: balanced solutionJessner solution See: Jessner solutionlactated Ringer solution See: Ringer, Sydneyliquor solutionAn aqueous solution of nonvolatile substances formerly used to prepare medicines.Locke-Ringer solution See: Locke solutionLugol solution See: Lugol solutionmolar solution1 MA solution containing a gram molecular weight or mole of the reagent dissolved in 1 L of solution.normal solutionAn obsolete term for a solution in which 1 L contains 1 g equivalent of the solute. This term is discouraged in the SI system. normal saline solutionAn isotonic saline solution. Synonym: physiological saline solution See: isotonic solutionophthalmic solutionA sterile preparation suitable for instillation in the eye.oral rehydration solution Abbreviation: ORS A solution used to prevent or correct dehydration due to diarrheal illnesses. The World Health Organization recommends that the solution contain 3.5 g sodium chloride; 2.9 g potassium chloride; 2.9 g trisodium citrate; and 1.5 g glucose dissolved in each liter of drinking water. physiological saline solutionNormal saline solution.polyethylene glycol electrolyte for gastrointestinal lavage solutionA solution for cleansing the bowel before colonoscopy and barium enema examinations. It is an isosmotic solution for oral administration, containing 236 g of polyethylene glycol 3350; 23.74 g of sodium sulfate; 6.74 g of sodium bicarbonate; 5.86 g of sodium chloride; and 2.97 g of potassium chloride added to water to make up a 4-L solution. For adults 4 L of the solution are given at the rate of 8 oz (240 mL) every 10 min until exhausted. The bowel will be cleansed within 3 to 4 hr. potassium arsenite solutionAn arsenical solution containing 0.95 to 1.5 g of arsenic trioxide for each 100 ml of solution.repair solutionAny solution given intravenously to treat an electrolyte or metabolic disturbance.replacement solutionA liquid given to a patient to increase concentrations of specific electrolytes or minerals. It is usually given intravenously, orally, enterally, or interosseously. Ringer solution See: Ringer, Sydneysaline solutionA solution of a salt, usually sodium chloride, and distilled water. A 0.9% solution of sodium chloride is considered isotonic to the body. A normal saline solution consists of 0.85% salt solution, which is necessary to maintain osmotic pressure and the stimulation and regulation of muscular activity. saturated solutionA solution containing all the solute it can dissolve. See: saturation pointsclerosing solutionSclerosant.scrub solutionA colloquial term for a skin cleanser for the removal of debris, dirt, microorganisms, oils, and scales from the skin of a patient before incision or instrumentation.seminormal solution Abbreviation: 05N or N/2 A solution containing one-half of a gram equivalent weight of reagent in 1 L of solution.sodium iodide I 125 solutionA standardized solution of radioactive iodide, 125I.standard solutionIn comparison or analysis, a solution containing a definite amount of a substance.strong ammonia solutionA solution containing approx. 28% ammonia in water.supersaturated solutionA solution in which the saturation point is reached but when it is heated it is possible to dissolve more of the solute. See: saturation pointtest solutionA dissolved reagent used for a specific laboratory purpose.tricitrates oral solutionA solution of sodium citrate, potassium citrate, and citric acid in a suitable aqueous medium. The sodium and potassium ion contents of the solution are approx. 1 mEq/ml.
