title: [Use of Meropenem in preterm newborns. Survey of the literature and case series].
abstract: OBJECTIVE
  The aim of this paper was to evaluate usefulness and safety of Meropenem in severe infections in neonatal intensive care unit (NICU) patients. New broad spectrum carbapenem class of -lactam antibiotics has been investigated for the treatment of a wide range of infections, including nosocomial infections with cephalosporin-resistant pathogens, an emergent problem in NICU, and meningitis. Meropenem represents the first cabapenem-class that has received Food and Drug Administration (FDA) approval for use in children 3 months of age and older. The pharmacokinetics of Meropenem has been well studied in preterm neonates.
  
  
  METHODS
  We report the use of Meropenem in 26 neonates with median gestational age (GA) of 27 weeks (25-32) and median birth weight of 940 g (510-1900), with severe infections due to Gram-negative or Gram-positive organisms, from 2001 to 2004. The median postnatal age was 21 days (4-75). Meropenem was administrated intravenously in 30 min at dosage of 20 mg/kg every 12 h (every 8 h in Pseudomonas Aeruginosa infections).
  
  
  RESULTS
  In all cases Meropenem has been used as second choice. No adverse effects (eosinophilia, trombocytosis or thrombocytopenia, increase in liver enzyme, increase in creatinine, diarrhea, vomiting and seizures) were observed. Clinical and bacterial response was ontaine in all cases but one.
  
  
  CONCLUSIONS
  This report suggests that Meropenem may be a useful and safe antimicrobial agent in neonatal infections caused by resistant organisms and in meningitis. Further studies are needed to confirm these results.
