Abstract:
Blood cultures are the gold standard for detecting bacteremia. We have studied the time to positivity of blood cultures in our neonatal unit to reduce antibiotic doses in patients with a negative blood culture. Empirical antibiotic treatment of neonatal sepsis could be withdrawn 24 hours after obtaining blood cultures.
