Current Practices in the Diagnosis and Management of Patent Ductus Arteriosus in Very Preterm Infants: A National Survey in Thailand
A 2024–2025 national survey of Thai pediatricians reveals substantial variation in the diagnosis and management of patent ductus arteriosus in very preterm infants, characterized by a lack of institutional guidelines, inconsistent echocardiographic criteria, and a preference for acetaminophen, underscoring the urgent need for standardized national protocols.

Imagine a tiny, fragile baby is born too early, like a seedling pulled from the soil before its roots are ready. Inside this baby's chest, there is a special tunnel called a "ductus arteriosus" that acts as a temporary detour for blood while they were growing in the womb. Usually, this tunnel closes up on its own shortly after birth, like a drawbridge lowering to stop traffic. But in very premature babies, this drawbridge sometimes gets stuck open. When it stays open, it's called a Patent Ductus Arteriosus (PDA). This is a bit like a leaky pipe in a house: if the water (blood) keeps flowing through the wrong path, it can flood the lungs and starve the rest of the body of pressure. Doctors have been arguing for years about the best way to fix this leaky pipe. Some say, "Wait and see, maybe it will fix itself," while others say, "Plug it up immediately with medicine or surgery." The big question is: How do we know which babies actually need the plug, and which ones are fine just waiting?
This study takes a look at how doctors in Thailand are handling this tricky situation. The researchers sent a survey to 133 pediatricians (doctors who treat children), asking them how they diagnose and treat these open tunnels. They wanted to see if there was a standard rulebook everyone follows, or if every doctor was playing by their own set of rules. The results show a bit of a chaotic kitchen: there is no single national recipe. Only about 1 in 5 doctors (22%) said their hospital even has a written guideline for PDA. Instead of a unified plan, the approach depends heavily on who is doing the treating.
The study found that doctors who specialize specifically in newborns (neonatologists) and general pediatricians often see the problem differently. When it comes to medicine, neonatologists prefer a drug called acetaminophen (the same stuff used for headaches and fevers in older kids) to close the tunnel, using it about 75% of the time. Other pediatricians were less convinced, using it only half the time. The study also revealed a difference in attitude: general pediatricians were more likely to believe that every open tunnel should be closed before the baby leaves the hospital, while the newborn specialists were more cautious, suggesting that not every leak needs a patch.
The doctors also use different tools to decide if the leak is "significant" enough to worry about. Most rely on measuring the width of the tunnel with an ultrasound, but they rarely check for more complex signs, like whether the blood is stealing pressure from the body or flooding the lungs. It's a bit like a mechanic judging a car engine only by how loud it is, without checking the oil pressure or the temperature. The study suggests that because there is no standard rulebook and doctors rely on their own experience, care varies wildly from one hospital to another. The authors conclude that Thailand needs a clear, national set of guidelines to make sure every baby gets the same, best possible care, rather than care that depends on which doctor happens to be on duty.
