You suspect a central-line associated bloodstream infection in a neonate: outline how you would investigate and manage this situation (sampling, empirical therapy, line management decisions, and communication with the medical team and family), and how you would minimise disruption to ongoing intensive care needs.

If I suspected a line infection (temperature instability, increased CRP, rising oxygen needs), I’d act promptly. I’d obtain paired blood cultures: from the central line and a peripheral site, collecting 0.5–1.0 mL per sample as soon as possible, ideally within 30 minutes, before antibiotics. If the baby is stable I’d wait for cultures; if unstable I’d start empirical IV antibiotics within 60 minutes (commonly vancomycin plus gentamicin pending local guidelines) and alert microbiology. Line decisions are pragmatic: remove immediately for tunnel infection, purulence, fungal suspicion or hemodynamic instability; if stable and organism likely coagulase-negative staph, consider keeping the line with targeted therapy and daily review. I’d organise alternate access/TPN continuation via peripheral or new line placement by experienced staff to minimise care disruption, update the consultant and explain the plan to parents in plain terms, and document cultures, timing and rationale in the notes.
