Question: 1 / 400

What medication is often administered to patients with traumatic brain injury to reduce intracranial pressure?

Furosemide

Mannitol

Mannitol is administered to patients with traumatic brain injury primarily to reduce intracranial pressure (ICP). Mannitol is an osmotic diuretic that works by drawing fluid out of the brain tissue and into the bloodstream, thereby decreasing cerebral edema and lowering ICP. This reduction in pressure is crucial for preventing further brain injury and optimizing neurological outcomes.

In contrast, furosemide, while also a diuretic, is more commonly used to manage fluid overload and does not specifically target intracranial pressure issues. The non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and aspirin are typically used for pain relief and inflammation but do not have a direct effect on intracranial pressure and could even increase the risk of bleeding in patients with head injuries. Therefore, Mannitol is the preferred choice for managing elevated ICP in trauma patients, making it the correct answer in this situation.
