Red flags
- A preterm infant who is grunting, retracting and desaturating at 3 hours of age has respiratory distress syndrome until proven otherwise — start CPAP and prepare for surfactant, do not observe
- Abdominal distension with bloody stools or bilious aspirates in a preterm infant is necrotising enterocolitis until proven otherwise — fast, decompress, obtain surgical review and radiograph
- A sudden rise in ventilator or oxygen need with a bounding pulse and widened pulse pressure signals a haemodynamically significant patent ductus arteriosus or an air leak — examine and image urgently
- Hypothermia on NICU admission is a preventable mortality risk — if the infant arrives cold, the thermal chain has failed and every degree below 36.5 C worsens outcomes
- A preterm graduate with loss of milestones or asymmetric tone at corrected age needs urgent developmental and neurological assessment — never attribute regression to prematurity alone
- Family collapse, parental mental illness or bonding failure during a long admission is a safeguarding signal — escalate psychosocial support before discharge, not after

Overview & Definition
Picture the 29-week infant born after spontaneous preterm labour — tiny, fragile, grunting in the delivery suite, skin translucent and heat pouring out of every centimetre of surface area. Your first minutes set the trajectory for a months-long NICU journey and a lifetime of neurodevelopmental risk. That is why preterm care is taught as a whole-of-journey discipline, not a single intervention. [1] [3]
Preterm birth is defined by gestational age at delivery. An infant born before 37 completed weeks is preterm; lower gestational age, higher risk across every organ system. The 26-week infant is a different patient from the 34-week infant — different respiratory vulnerability, different brain risk, different feeding immaturity, different prognosis — and your plan must reflect that gradation rather than treating all preterm infants as one homogeneous group. [1] [6]
Globally, roughly one in ten live births is preterm, and prematurity remains the leading cause of death in children under five. The burden falls hardest in low- and middle-income settings, but no region is spared — which is why a fellowship answer must be region-aware and equity-literate, not a single textbook pathway.
