saltvattenslösning

Saltvattenslösning, also known as saline solution or normal saline, is a mixture of sodium chloride (NaCl) dissolved in water. The concentration of salt in a typical medical saline solution is 0.9%, meaning it contains 9 grams of sodium chloride per liter of water. This specific concentration is isotonic, meaning it has the same osmotic pressure as human blood and other body fluids.

Due to its isotonic nature, saltvattenslösning is widely used in medicine. It is commonly employed for intravenous fluid replacement, to rehydrate patients or to administer medications. Its inertness and compatibility with the body make it a safe choice for these purposes. It is also used as a general cleaning agent for wounds, contact lenses, and nasal passages, as it helps to remove debris and irritant substances without causing significant cell damage.

Beyond medical applications, saltvattenslösning has other uses. In scientific research, it serves as a standard solution for various experiments and procedures. In some home remedies, it can be used for gargling to soothe a sore throat or for rinsing nasal passages to alleviate congestion. The preparation of saltvattenslösning involves dissolving purified sodium chloride in sterile water, ensuring it is free from contaminants that could be harmful if introduced into the body.
