William O. Mordi-Tarnow is a Neonatologist based in Sydney, NSW, Australia. He looks after newborn babies who need extra help in the first days of life, when things can change quickly and close monitoring matters.
In neonatal care, the focus is often on babies who were born early or who are dealing with serious health problems soon after birth. William works with families and the wider hospital team to support babies through the critical early period, with treatment planned around what each baby needs most at the time.
Common reasons babies may be referred include complications linked to prematurity, breathing problems, and infections. This can include things like premature infant care, infant respiratory distress syndrome, and issues such as neonatal sepsis or other newborn infections. Some babies also have conditions that affect how well the body handles blood flow and oxygen, like asphyxia neonatorum and cerebral hypoxia.
There are also brain and blood-related problems that neonatology teams manage. In many cases, this includes concerns such as intraventricular haemorrhage of the newborn and newborn polycythaemia. Jaundice is another common issue in early life, and babies may need extra checks and treatment depending on how their bilirubin levels are trending.
At times, the work also involves digestive and circulation issues. For example, necrotizing enterocolitis can affect the gut in some newborns and needs careful, ongoing care. William also manages respiratory complications like infantile pneumothorax, where air can collect around the lungs and make breathing harder.
Neonatology doesn’t stop at the first week, either. William’s care can include babies with longer-term risks after time in intensive newborn settings. This may involve follow-up support for eye-related complications such as retinopathy of prematurity. It can also include care for certain movement and muscle concerns, like spastic diplegia (infantile type).
When it comes to viral illnesses, newborns can get hit harder than older children, so conditions like viral gastroenteritis may also come up. Over time, the goal stays the same: help babies stabilise, support recovery, and make sure the plan keeps pace as the situation changes.
