Introduction
Normal saline is a solution. Normal saline contains substances such as sodium chloride, and its composition is similar to that of extracellular fluid in the human body, hence the name "normal saline." The main components of normal saline are sodium chloride and water, with a concentration of 0.9%. In addition, normal saline also contains small amounts of ions such as potassium, calcium, and magnesium, as well as buffering agents such as bicarbonate and phosphate ions.

Normal saline is a sterile, non-toxic, colorless, transparent liquid with a pH of approximately 7.4, closely resembling the physiological environment within the human body. Due to its similarity to human extracellular fluid, normal saline can be rapidly absorbed and utilized by the body, and is commonly used for fluid replacement, intravenous infusion, gastric lavage, and other treatments. Moreover, it can also be used in medical procedures such as wound cleaning and enemas.
Although normal saline is a safe and effective medical preparation, attention must still be paid to dosage and administration methods during use to avoid adverse reactions. When using normal saline, it is important to follow a doctor's advice and instructions to ensure safe and effective treatment outcomes.
