Normalsalzlösung

Normalsalzlösung, also known as saline solution or physiological saline, is a sterile solution of sodium chloride in water. It typically contains 0.9 grams of sodium chloride dissolved in 100 milliliters of water, making it isotonic with human blood and other bodily fluids. This isotonic property means it has the same osmotic pressure as these fluids, preventing damage to cells when introduced into the body.

The primary use of normalsalzlösung is in medicine as an intravenous fluid. It is administered to rehydrate patients, to restore electrolyte balance, and as a vehicle for delivering medications. It is also commonly used as a cleansing agent for wounds and contact lenses, and in laboratory settings for various experimental procedures. Its inertness and compatibility with biological tissues make it a versatile and essential medical and laboratory tool. The sterility of the solution is crucial to prevent infection when used in medical applications. Normalsalzlösung is readily available in various sizes of sterile containers.
