Respiratory distress syndrome (RDS)—when premature babies struggle to breathe—is a leading cause of serious complications in infants born too early. Doctors treat it with surfactant, a medication that helps lungs expand. But delivering it has always been difficult: either doctors pass a tube deep into the baby's airway (invasive), or they pause breathing support to administer it (which has its own risks).
A team of researchers in China developed a new double-channel breathing tube designed to deliver surfactant without stopping the baby's ventilation. They tested this innovation against the current best method, called LISA (Less Invasive Surfactant Administration), in 138 premature babies across six major hospitals.
New technique performs as well as the current gold standard
Both methods achieved similar outcomes. About 14.5% of babies using the new technique needed full mechanical ventilation within 72 hours, compared to 18.8% in the LISA group—a difference that wasn't statistically significant (meaning it could be due to chance). Hospital stays, time on breathing support, and oxygen therapy duration were comparable between the two groups. Serious complications like chronic lung disease, brain bleeding, and feeding difficulties occurred at similar rates.
Why this matters beyond Singapore's top hospitals
Singapore's neonatal intensive care units (NICUs) already use advanced techniques like LISA, and families here have access to world-class premature baby care. However, this research is particularly valuable across Asia, where access to specialized NICU expertise or equipment varies. A simpler, equally effective technique could allow smaller hospitals or developing regions without LISA expertise to deliver this lifesaving treatment to more premature babies who need it.
One finding worth noting
Babies in the new technique group had slightly lower blood pH levels immediately after the procedure. The researchers couldn't determine whether this difference has real clinical importance, so this warrants further investigation in larger studies before drawing firm conclusions.
