IV fluids
Intravenous (IV) fluids are given to patients intravenously – which means directly through the circulatory system. Fluids come in plastic bags or glass bottles. A needle is used so that the fluids go directly from the bag or bottle into your system.
Many times, IV fluids are given as a means to rehydrate patients who have lost fluids due to illness or injury. Fluids are also given to maintain fluid volume.
Antibiotics and other medications are also given intravenously.
