Is sodium oxide injection the same as physiological saline?

Sodium chloride injection is not entirely the same as physiological saline; only sodium chloride injection with a concentration of 0.9% is referred to as physiological saline. There is a conceptual inclusion relationship between the two, and they must be clearly distinguished based on specific needs when used. The detailed analysis is as follows:

A 0.9% sodium chloride injection has an osmotic pressure closely matching that of human plasma and tissue fluid. Its composition resembles that of human body fluids, helping prevent cellular damage caused by osmotic imbalance. This solution is widely used in medical practice for fluid replacement, drug dilution, wound irrigation, and other purposes, making it a fundamental and commonly used clinical medical product. Besides the 0.9% concentration, sodium chloride injections are also available in other concentrations such as 10%, none of which are classified as physiological saline. High-concentration sodium chloride injections are primarily used to correct specific conditions like hyponatremia and require strict control of dosage and infusion rate. They should not be used indiscriminately as physiological saline, as this could lead to problems such as electrolyte imbalances.

The use of medical products requires precise differentiation of specifications. The selection of sodium chloride injection should be based on actual medical needs. Whether for fluid replacement or other medical procedures, the appropriate concentration of solution should be chosen under professional guidance to ensure safety and effectiveness.
