Which statement best reflects a preventive measure to reduce IVH risk during stabilization of a preterm infant?

• A. Allow BP and CO2 to fluctuate freely during stabilization.
• B. Provide rapid fluid boluses to normalize BP.
• C. Hyperventilate aggressively to lower CO2.
• D. Maintain stable blood pressure and CO2 levels during stabilization to reduce IVH risk.

Answer: (D)

The main idea here is that preventing sudden swings in brain perfusion during the vulnerable stabilization period of a preterm infant helps reduce the risk of intraventricular hemorrhage. In preterm babies, cerebral autoregulation isn’t fully developed, so cerebral blood flow is very sensitive to systemic blood pressure and carbon dioxide levels. If blood pressure or CO2 flip rapidly, the delicate vessels in the germinal matrix can rupture. Maintaining stable blood pressure and maintaining normocapnia (stable CO2) during stabilization minimizes those swings in cerebral perfusion. Avoid letting CO2 rise or fall abruptly, and steer clear of rapid, large fluid boluses that could push BP up or down quickly. Gentle, controlled ventilation helps keep CO2 in a safe range, and careful hemodynamic management keeps BP steady, both of which support more stable cerebral blood flow and lower IVH risk. Options that allow fluctuations in BP or CO2, or that aggressively alter CO2 (like hyperventilating), would create abrupt changes in cerebral blood flow and could increase IVH risk, so they’re not appropriate.
