For the patient with head injury and increased Intracranial Pressure (ICP), an osmotic diuretic, such as mannitol, is very helpful. An osmotic diuretic works by creating an osmotic gradient in the blood by the presence of the additional osmolyte (mannitol). In other words, the osmolyte stays in the bloodstream and creates a greater osmotic force to pull water out of tissues and third spaces (interstitium of cerebrum). This aids in alleviating the addition ICP by fluid removal.
The extra fluid that was "sucked" into the bloodstream via osmosis, can then travel to the kidneys and be filtered out into the urine (diuresis). This explains its two purposes as an "osmotic" and a "diuretic."
Living things need water in their cells. Water is the universal solvent - most of the chemicals a cell needs is dissolved and transported in water. Water is an environment where chemical reactions can occur and water is needed in many of those reactions - like the hydrolysis reaction (needed in the break down of food molecules). If a cell becomes dehydrated chemical reactions slow down. Chemical balance of the cell is changed as waste materials are not removed fast enough, food is not broken down, etc. Water also helps regulate the heat that can build up in a cell during chemical reactions. A dehydrated cell = increase in cell temp. Water content of a cell also affects the pH of a cell environment. Certain reactions occur better at certain pH. Homeostasis is maintaining a balance with the the environment. Without water the balance is upset.
