An infant with increased work of breathing and micrognathia is admitted. Which positioning best decreases airway distress?

• A. Supine
• B. Prone
• C. Lateral
• D. Trendelenburg

Answer: (B)

When an infant has increased work of breathing with micrognathia, the goal is to maximize airway patency by using gravity to move soft tissues away from the airway. The prone position accomplishes this by allowing the tongue and supporting soft tissues to shift forward and off the back of the airway, which enlarges the passage for air and reduces obstruction. This direct relief of glossoptosis lowers respiratory effort and improves oxygenation. In the supine position, the tongue and soft tissues tend to fall posteriorly, narrowing the airway and worsening distress. Lateral positioning can help a bit, but it doesn’t provide the consistent anterior displacement of the tongue seen with prone positioning. Trendelenburg places the body with the head lower than the feet and can worsen airway edema and obstruction in an infant, making breathing more difficult. So, the prone position is the best choice to decrease airway distress in this scenario.
