Which statement best reflects a primary goal of ICP-directed therapy within the first 72 hours after TBI?

• A. Control ICP
• B. Maximize brain edema
• C. Delay ventilation optimization
• D. Focus only on nutrition and caloric goals.

Answer: (A)

The main idea is to prevent secondary brain injury by keeping intracranial pressure under control so the brain can receive adequate blood flow. In the first 72 hours after a traumatic brain injury, swelling and tissue damage tend to raise ICP. If ICP rises, cerebral perfusion pressure drops, which can lead to ischemia and even brain herniation. So, the primary goal of ICP-directed therapy is to lower and stabilize ICP to maintain sufficient CPP and protect brain tissue. That’s why management focuses on measures that reduce ICP: elevating the head of the bed to about 30 degrees to improve venous drainage, ensuring adequate sedation and analgesia, avoiding factors that boost ICP, using hyperosmolar therapies (like mannitol or hypertonic saline) to draw fluid out of swollen brain tissue, draining CSF if an external ventricular drain is in place, and carefully optimizing ventilation to maintain normal or near-normal CO2 levels, which influence cerebral blood flow. Invasive ICP monitoring may guide these interventions in real time. While nutrition and caloric goals are important for overall recovery, they do not compete with ICP control as the primary objective in this early window. Likewise, strategies that increase edema or delay ventilation optimization would worsen outcomes, not improve them.
