A nurse is caring for a preterm infant diagnosed with respiratory distress syndrome (RDS). Which nursing intervention should be the priority to optimize respiratory function?

Primary Indication: To optimize ventilation-perfusion matching and stabilize the chest wall in spontaneously breathing preterm infants with Respiratory Distress Syndrome (RDS).

Physiological Rationale: The prone position counteracts the highly compliant chest wall of the preterm infant. It reduces paradoxical inward rib cage movement during inspiration, thereby increasing and maintaining Functional Residual Capacity (FRC). This prevents alveolar collapse (atelectasis) and improves oxygenation without necessarily increasing energy expenditure.

Implementation Protocol:

• Assessment: Ensure the infant is hemodynamically stable. Continuous cardiorespiratory and pulse oximetry monitoring must be in place.
• Positioning Technique: Gently position the infant prone with hips and knees flexed in a contained, midline orientation. The head should be turned to one side, alternating sides with each care interval to prevent positional plagiocephaly. Use a small, soft roll under the hips to promote flexion.
• Airway Management: Ensure the nares and mouth are free from obstruction by bedding. The neck should be in a neutral or slightly extended position to maintain a patent airway.
• Safety Precaution: Prone positioning is only safe for hospitalized infants under continuous monitoring. It is strictly contraindicated for unsupervised sleep due to the risk of Sudden Infant Death Syndrome (SIDS).

Contraindications & Cautions: Avoid in infants with an unrepaired omphalocele, gastroschisis, or immediately post-extubation if the infant is unstable. Discontinue and reposition if the infant exhibits increased work of breathing, desaturation, or bradycardia.

Interdisciplinary Coordination: The prone position should be integrated into the daily care plan in collaboration with the neonatologist and respiratory therapist, especially for infants on Continuous Positive Airway Pressure (CPAP) or mechanical ventilation, to maximize recruitment of dependent lung zones.
