Problem-solving in clinical practice: Persisting respiratory distress in a premature infant.

The deterioration of a previously stable preterm infant is a common scenario on the neonatal unit. The the most common bacterial causes of deterioration are nosocomial infections, such as coagulase-negative Staphylococcus and Staphylococcus aureus Non-infective conditions such as pulmonary haemorrhage, anaemia of prematurity and necrotising enterocolitis may also cause preterm infants to deteriorate. This case chronicles the unusual diagnostic journey of an infant born at 27+1 weeks who deteriorated at 26 days of life and did not respond to antimicrobial therapy as anticipated.
