What are the functions and effects of normal saline

The main function of normal saline is to dissolve medicines. It can also be used for oral rehydration. In addition, it can rinse wounds, reduce inflammation and kill bacteria.

1. Dissolving drugs: Normal saline can often be used as a solute to dissolve some drugs. Commonly used drugs include antibiotics. Especially during the injection of antibiotics, some normal saline is needed. For example, in infusion therapy, most of them are dissolved with raw saline.

2. Oral rehydration: In daily life, if a lot of vomiting and diarrhea occur, resulting in water and electrolyte imbalance in the body, rehydration through oral saline can alleviate the symptoms of electrolyte imbalance. This is mainly because saline contains a certain amount of calcium ions and chloride ions, which are used to replenish the body's fluids and maintain electrolyte balance.

3. Rinse the wound, reduce inflammation and kill bacteria: After the skin is injured or bruised, it needs to be improved by washing with saline solution, which can have a certain anti-inflammatory and bactericidal effect and avoid symptoms of local infection on the skin.

When using salt water in daily life, you need to choose the appropriate method and concentration according to your own situation to avoid inappropriate concentration, failure to achieve the desired effect, and affecting your health.
