What is saline solution?

Answer 1

It is basically as solution of salt and water.

There are many concentrations of "saline solution" the most common of which is "normal saline" which is 0.9% sodium chloride (NaCl) in water.

Saline solution is primarily used to irrigate and clean wounds. The irrigation force created by the spray is sufficient to dislodge minor foreign particles such as small twigs and gravel that may have gotten into the wound.

In a hospital and medical setting, saline solution may be administered to aid in hydrating a patient. In Pre Hospital Emergency Care, it is often combined with other drugs (called a bolus). This dilutes the drugs and is administered through an intravenous line. A saline tube will state if it is fit for injection or not. The big tubes generally cannot be injected and will say "Not For Injection" while the smaller tubes are printed with "Injection Solution BP"

Answer 2

A buffered saline solution is a water-based salt solution. It is often used in chemical and biological experiments because the osmolarity, ion concentrations, and pH of the solutions match those of the human body and are thus nontoxic to most cells.

Answer 3

Saline solution is a mixture of salt and water that has the same concentration of salt as your body's cells and blood. It is often used for medical purposes, such as cleaning wounds, rinsing contact lenses, and hydrating or diluting medications for injections.
