👉 Medicines fluid, also known as intravenous (IV) fluids or crystalloids, is a type of liquid administered directly into a vein to provide rapid hydration and deliver essential nutrients, electrolytes, or medications to the body. These fluids are crucial in medical settings for treating dehydration, shock, and various other conditions by quickly restoring fluid balance and supporting organ function. Common types include normal saline (NaCl), lactated Ringer's solution, and dextrose solutions for glucose replacement. IV fluids are carefully formulated to match the patient's specific needs and can be administered at varying rates depending on the clinical situation.
