What is normal saline?

Normal saline, also known as isotonic saline or physiological saline, is a solution of water and 0.9% sodium chloride. It is commonly used in medical settings for a variety of purposes, including intravenous (IV) hydration, maintaining fluid balance, and diluting medications for administration. Normal saline is isotonic, meaning it has the same concentration of salt as the body's cells, making it compatible with the body's natural fluids.

Normal saline is often used to treat dehydration, restore electrolyte balance, and flush out wounds or medical devices. It is also used as a diluent for IV medications and as a vehicle for intravenous administration of drugs.

Normal saline is typically clear and colorless, and comes in sterile plastic bags or bottles for intravenous administration. It is considered safe for most patients, although it may not be suitable for those with certain medical conditions, such as congestive heart failure or kidney disease.

Overall, normal saline is a versatile and widely used solution in medical practice that plays a crucial role in maintaining patients' health and well-being.
