Saline and normal saline is not the same, saline only sodium chloride, normal saline in the composition is not a single.

1, concentration:

The concentration of saline for human use is generally about 0.9%, is a medical supply, purity, concentration requirements are strict, no other additions. Can dilute injectable injections or instead of plasma, ordinary saline is ordinary table salt or industrial salt diluted with water, the concentration of the liquid, there is no preoccupation,

2, the use of:

Saline in the medical aspects of the role of the more complex, in addition to dilute injectable injections and instead of plasma, but also to avoid cellular rupture, for the body fluids do not replenish fluids, replenishment of electrolytes and detoxification, etc., has a very important medical It has a very important medical value. Saline is usually made from refined salt and is much less pure, and deliberately added with things like iodized salt.

Extended information:

The effects of saline:

1. Avoiding Cellular rupture

Saline water has the same osmotic pressure as extracellular, and will not allow cells to rupture due to dehydration or excessive water absorption.

2, cleaning wounds

Saline is actually a low concentration of salt water, often used as a wound cleaning, as well as replenishing blood volume.

3, correct acidosis

The method of alternating saline and 5% or 10% GS solution with sedation can replenish electrolytes, correct acidosis, overcome ketoacidosis, and can also replenish water and calories.

4, maintain the tension of body fluids

Saline can supply dielectrics and maintain the tension of body fluids, which can be used for rehydration and other medical purposes, and is also commonly used for in vitro cultivation of living tissues and cells.
