Surfactant Therapy Via Supraglottic Airway to Preterm Neonates With RDS in Vietnam
Surfactant Therapy Via Supraglottic Airway Device Versus Endotracheal Intubation to Prevent Mechanical Ventilation in Preterm Neonates With Respiratory Distress Syndrome: An Open-label, Non-inferiority, Randomized Controlled Trial at a Level-III Neonatal Intensive Care Unit in Vietnam

Conditions
Summary
Preterm babies often have trouble breathing because their lungs are not fully developed. This condition is called respiratory distress syndrome (RDS). A medicine called surfactant helps their lungs open up and work better. It is usually given through a procedure called INSURE, where a breathing tube is placed into the baby's trachea (via an endotracheal tube) to deliver the medicine. While effective, this method is invasive and can be uncomfortable and risky for the baby. A newer, less invasive method called SALSA uses a soft mask placed in the throat (a laryngeal mask airway) instead of an endotracheal tube to give the surfactant. This randomized controlled trial will compare SALSA to the traditional INSURE method to see if it works just as well in preventing the need for invasive breathing support within three days of treatment. The study will include preterm babies born before 34 weeks of pregnancy and weighing at least 750 grams, at Phu San Hanoi Hospital in Vietnam. If SALSA is found to be safe and effective, it may offer a gentler, less invasive, and easier-to-perform option for treating respiratory distress syndrome in premature babies.

Interventions
While the infant is spontaneously breathing on nasal CPAP, the NICU physician will place the supraglottic airway device (SAD) and assess airway adequacy via CO₂ detection, chest movement, bilateral breath sounds, gastric insufflation, oxygen saturation, and heart rate. Each placement attempt should last no more than 30 seconds, with up to two attempts allowed. Surfactant (Curosurf 200 mg/kg) will be given slowly in 1-2 ml aliquots via a CE-marked preterm-sized SAD, Neo i-gel® (sizes 0.85, 0.75, 0.65; Intersurgical Ltd). The infant should primarily breathe spontaneously with PEEP from a T-piece resuscitator and receive gentle PPV if needed. PPV is continued for 30 seconds after surfactant administration before SAD removal. A reservoir bag may be used secondarily to provide PPV. If surfactant delivery via SALSA fails, the INSURE method (Intubation-Surfactant-Extubation) will be attempted.
Study participants will receive surfactant therapy administered via brief endotracheal intubation - surfactant administration - and extubation (INSURE). Infants will be ventilated using a T-piece resuscitator with PEEP of 6 cm H20 and positive pressure ventilation (20 cm H20) for a couple of minutes (no more than 15 minutes) with adjustable FiO2. No mechanical ventilation will be used. Secondarily a reservoir-bag will be used for ventilation.
