Physiological saline can be used to wash the wound.

1. What is physiological saline?

According to the scientific designation, physiological saline is an isotonic solution of sodium chloride, prepared at the rate of 0.9% and has an osmotic pressure equivalent to the fluid in our body.

0.9% NaCl solution is not a prescription drug and is quite safe, so it is widely used in life and medicine. We can completely use this product for many objects including children, pregnant women and babies.

Basically, physiological saline will be divided into 2 types:

Type 1: Used to clean skin wounds, eye drops, clean nasal cavity, ear cavity, gargle – throat, …
Type 2: Prepared in a solution for intravenous infusion in the body (also known as sea water). Unlike physiological saline for external use, physiological saline in seawater is distilled, prepared and preserved in a completely sterile environment. When used, sea water will be injected intravenously by drip with the volume prescribed by the doctor.

The most important effect of 0.9% NaCl solution is to clean the wound. Accordingly, its salt concentration is very low, so it is not as painful as specialized antiseptics. Normally, you can completely pour physiological saline directly on the bleeding area to wash away dirt, blood, … and then proceed with the next first aid treatment steps.

So in fact, washing the wound often with physiological saline has the effect of supporting first aid, cleaning rather than disinfecting.
