Surfactant administration refers to the medical practice of delivering synthetic or natural surfactant into the lungs of premature infants or adults with severe respiratory distress. Surfactant is a complex mixture of lipids and proteins that reduces surface tension within the alveoli, preventing their collapse and improving lung compliance. This treatment is primarily used in neonatal intensive care units (NICUs) to manage respiratory distress syndrome (RDS), a condition commonly affecting premature infants due to insufficient surfactant production.

The procedure typically involves the use of exogenous surfactant, often administered through an endotracheal tube inserted into the infant’s airway. The surfactant is delivered in small doses, often repeated over several hours or days, depending on the clinical response. Common synthetic surfactants include beractant (Survanta), poractant alfa (Cayston), and lucinactant (Surfaxin), each formulated to mimic natural surfactant properties. In some cases, natural surfactant extracted from animal lungs may also be used, though synthetic alternatives are preferred to reduce infection risks.

Indications for surfactant administration extend beyond neonatal RDS to include meconium aspiration syndrome, pneumonia, and acute respiratory distress syndrome (ARDS) in adults. The timing and method of administration are critical; in neonates, early intervention within the first few hours of life is associated with improved outcomes. Complications are rare but may include transient oxygen desaturation, bronchospasm, or rare cases of infection if sterile techniques are not followed.

Surfactant therapy has significantly improved neonatal survival rates and reduced the need for mechanical ventilation in high-risk infants. Ongoing research explores its potential in adult respiratory conditions and alternative delivery methods, such as intranasal administration, to enhance efficacy and patient comfort. Clinical guidelines from organizations like the American Academy of Pediatrics and the World Health Organization support its use in specific clinical scenarios, emphasizing evidence-based practice.
