Which statement is true about the use of hyperosmolar therapies for ICP management in TBI?

• A. They are always given as the first therapy on admission.
• B. They are never used in pediatric patients.
• C. They should be avoided in hypotension.
• D. They are considered when other measures fail to control ICP.

Answer: (D)

Hyperosmolar therapies lower ICP by increasing serum osmolality, drawing water out of swollen brain tissue into the bloodstream to reduce brain volume. They’re not the first move on admission; initial ICP-control steps include optimizing ventilation, sedation, head position, blood pressure to maintain cerebral perfusion, and drainage if available. These therapies are used when ICP remains elevated despite those measures, as an escalation option. They can be used in pediatric patients with appropriate dosing and careful monitoring. They’re not categorically avoided in hypotension—hemodynamic stability should be established, and osmotherapy used with caution to avoid worsening perfusion or fluid balance. So the statement that best fits is that they are considered when other measures fail to control ICP. Monitoring of osmolality and electrolytes is essential to prevent toxicity.
