Introduction

Under normal circumstances, physiological saline generally refers to sodium chloride solution and should be used strictly as directed by a physician. Physiological saline specifically refers to 0.9% sodium chloride, which is a sterile aqueous solution of sodium chloride; solutions with other concentrations of sodium chloride are not considered physiological saline. Since the osmotic pressure of physiological saline is approximately equal to that of human plasma and tissue fluid, it can be used for fluid replacement to replenish bodily fluids.

Under normal circumstances, physiological saline is generally sodium chloride, and it should be used strictly as directed by a healthcare professional. The specific details are as follows:

Physiological saline primarily refers to a 0.9% sodium chloride solution—an isotonic, sterile aqueous solution of sodium chloride. Solutions with other concentrations of sodium chloride are not considered physiological saline. Since the osmotic pressure of physiological saline is approximately equal to that of human plasma and tissue fluid, it can be used for fluid replacement therapy to correct disturbances in water, electrolyte, and acid-base balance. Additionally, physiological saline can be used to clean skin wounds such as those from trauma or burns, and to irrigate surgical sites, eyes, urethras, and sterile tubing systems. It helps remove debris and foreign matter, prevent infection, and is also indicated for dehydration caused by various conditions, including hypotonic, isotonic, and hypertonic dehydration, as well as hyperosmolar non-ketotic diabetic coma.

Physiological saline should only be used under the guidance of a physician. Do not use it indiscriminately to avoid potential adverse effects. During use, proper skin cleansing and care should also be maintained to promote skin health.
