What treatment options are available for RDS?

• A. Inhaled nitric oxide
• B. Exogenous surfactant administration
• C. Mechanical ventilation only
• D. Chest physiotherapy

Answer: (B)

The treatment option of exogenous surfactant administration is the most effective intervention for Respiratory Distress Syndrome (RDS). RDS primarily occurs due to a deficiency of surfactant, which is essential for reducing surface tension in the alveoli and facilitating normal lung expansion. Administering exogenous surfactant directly improves lung function by replenishing the deficient surfactant, thereby reducing the risk of alveolar collapse and improving oxygenation in affected neonates.

This treatment not only helps improve respiratory mechanics but can also decrease the need for supplementary oxygen and mechanical ventilation, leading to better overall outcomes for infants diagnosed with RDS. The use of surfactant is a standard, evidence-based practice in the management of infants at risk for or diagnosed with RDS.

Other treatment options mentioned may be part of the overall management strategy, but they don’t address the underlying surfactant deficiency as directly as surfactant administration does. For instance, inhaled nitric oxide can help in managing pulmonary hypertensive episodes, mechanical ventilation aids in providing respiratory support, and chest physiotherapy is generally not a primary treatment for RDS but can be considered in broader supportive care measures or for other respiratory ailments. Therefore, exogenous surfactant administration stands out as the
