Mechanism of action

D5W is a hypotonic crystalloid solution containing 5 grams of dextrose per 100 mL of sterile water. The dextrose is rapidly metabolized by cells for energy, leaving behind free water that distributes across total body water compartments. It is used for hydration, maintenance of electrolyte balance, and provision of modest caloric support in clinical settings.
