A solution of any salt, but usually referring to sodium chloride.
A solution made of distilled water and sodium chloride, which is introduced into the body intravenously through a drip.
An isotonic liquid preparation of salt and distilled water used for infusion or irrigation.
A 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 (one having an osmolality similar to that of blood serum) consists of 0.85% salt solution, which is necessary to maintain osmotic pressure and the stimulation and regulation of muscular activity.
A solution of salt dissolved in water forms what is known as normal saline. This particular saline solution possesses a salt concentration that is equivalent to that of the human body, measuring at 0.9%. By closely matching the salt concentration found within our bodies, normal saline serves a variety of purposes. It finds extensive use in medical settings, such as intravenous therapy and wound irrigation, where maintaining the delicate balance of fluids and electrolytes is of utmost importance. With its salt concentration mirroring that of the body, normal saline proves to be a safe and effective solution for numerous healthcare interventions, aiding in the restoration and regulation of vital physiological processes.
A typical, or more accurately, physiological saline solution comprises 0.9 percent sodium chloride and matches the salt content of bodily tissues, preventing any osmotic pressure in either direction when used as a mild irrigation solution. In cases of first aid, you can create a similar “normal” saline solution by dissolving a level teaspoon of regular salt in a pint of boiled water.
