After surgery what glucose solution would be given intravenously?

0.9% saline or 5% dextrose in water (D5W) are commonly used intravenous (IV) fluids that can be given after surgery. The choice of fluid depends on the patient's specific needs and medical condition.

0.9% saline is an isotonic solution, meaning it has the same concentration of solutes as the fluid inside cells. It is often used to replace lost fluids and electrolytes, such as sodium and chloride. 0.9% saline is commonly used for short-term fluid resuscitation and is not a source of calories or carbohydrates.

5% dextrose in water (D5W) is a hypotonic solution, meaning it has a lower concentration of solutes than the fluid inside cells. It contains dextrose, a simple sugar that can be broken down and used for energy by the body. D5W is often used to provide fluids and calories to patients who are unable to eat or drink.

The decision on which glucose solution to use after surgery is made by a healthcare professional based on the patient's individual needs and medical conditions. Factors such as fluid and electrolyte balance, nutritional status, and the underlying medical condition are considered when selecting the most appropriate IV fluid.
