Is glucose sodium chloride a normal saline?
Disease description:
During previous IV infusions, some bags were labeled as "Glucose and Sodium Chloride" while others were labeled as "Normal Saline." I would like to ask, is Glucose and Sodium Chloride equivalent to Normal Saline?

Glucose sodium chloride is not the same as normal saline; they are two different intravenous fluid medications.
Normal saline, also known as sodium chloride injection or sterile normal saline, is a 0.9% sodium chloride solution. Its osmotic pressure is similar to that of human extracellular fluid and it is primarily used for fluid replacement, correcting dehydration, or maintaining circulation. Clinically, normal saline is mainly used to treat dehydration, hyponatremia, and can also be used for diluting medications.
Glucose sodium chloride injection, on the other hand, is a solution formed by adding glucose to normal saline. It can provide both water and electrolytes, as well as supply energy, making it suitable for patients requiring simultaneous replacement of glucose and sodium chloride, such as those with hypoglycemia or dehydration. In certain specific situations, such as when a patient is unable to eat or requires energy supplementation, physicians may choose to use glucose sodium chloride injection.
These two solutions differ in composition, function, and indications, and glucose sodium chloride should not simply be considered as normal saline. Physicians will choose the appropriate medication based on the patient's specific condition.
