Should 5% dextrose solution or 10% dextrose solution be used for fluid replacement?

Generally, fluid replacement can be performed using either 5% dextrose solution or 10% dextrose solution, depending on the patient's specific medical condition. The details are as follows:

1. 5%

During intravenous infusion, a 5% glucose solution has an osmotic pressure equivalent to that of human plasma. It effectively provides energy and replenishes fluid volume, thereby improving the body's nutritional status. Once administered, the 5% glucose solution is rapidly absorbed and metabolized, typically without causing vascular irritation or adverse reactions. It is commonly used in patients with insufficient blood volume, such as those experiencing sudden fainting or acute gastroenteritis.

2. 10%

A 10% glucose solution is a hypertonic solution and has a certain diuretic effect. It is primarily used to correct hypoglycemia, a condition in which a patient's blood glucose level falls significantly below the normal range, leading to various clinical symptoms. Since consuming sugar-containing foods may restore blood glucose levels too slowly, intravenous administration of 10% glucose solution is required for rapid relief. This concentration is also used in the treatment of hyperkalemia.

The therapeutic applications vary depending on the concentration of glucose solution used during infusion. Solutions must always be prepared by qualified medical professionals. If any discomfort occurs during infusion, patients should promptly inform their doctor to avoid delays in treatment.
