Cushing triad in pediatric patients with increased intracranial pressure tends to appear how relative to adults?

• A. More quickly
• B. More slowly
• C. Not at all
• D. With the same timing

Answer: (B)

Cushing triad signals a dangerous rise in intracranial pressure and is a late brainstem response that aims to preserve cerebral perfusion. In children, the skull is more compliant early on because sutures and fontanelles aren’t yet fused, allowing some expansion without an immediate spike in ICP. This greater intracranial tolerance means it takes a larger increase in pressure and time for brainstem ischemia to trigger the reflexes of the triad. Therefore, in pediatric patients, that classic hypertensive, bradycardic, and irregular respiration pattern tends to appear more slowly than in adults. Keep in mind kids may show nonspecific signs first, and the triad may be incomplete, so high suspicion is essential with any sign of raised ICP.
