What intravenous fluid you can give to a patient with head injury increased Intracranial pressure and give the rationale?

In patients with head injury and increased intracranial pressure (ICP), hypertonic saline (e.g., 3% saline) is often administered. This solution helps to draw water out of the brain tissue and into the vascular space through osmosis, thereby reducing cerebral edema and lowering ICP. Additionally, it can help maintain blood pressure and improve cerebral perfusion, which is critical in managing head injuries. However, careful monitoring of serum sodium levels and fluid balance is essential to avoid complications.
