Question

. Explain how principles of osmosis can be used in the treatment of a patient suffering from cerebral oedema

Answer 1

Explanation:

In the event of plasma hypotonicity, cerebral cells expel active osmotic molecules to reduce the osmotic gradient and water movement thereby reducing edema. The opposite reaction is observed in the case of hypertonic insult. This cerebral osmoregulation becomes more effective, the slower the osmotic disorder.

Answer 2

Explanation:

Osmotherapy

Osmotherapy is a technique meant to draw water out of the brain. This is done using osmotic agents such as mannitol, or high-salt saline. Osmotic therapy also helps improve blood circulation. This will help reduce swelling and ICP in the skull.
