Description
Summary:	A retrospective study on nosocomial bloodstream infection (NBSI) in pediatric patients hospitalized at Siriraj Hospital from January 1996 to December 1999 was performed. Of the 18,087 blood specimens sent for culture, 533 (3%) were positive for organisms after 72 hours of hospitalization and were defined as NBSI. The rate of NBSI detected in blood culture specimens was highest among neonates (5.2%). Gram-positive cocci and gram-negative rods caused NBSI in an equal proportion (46% and 44% respectively) and Candida caused 10 per cent of NBSI. Coagulase-negative staphylococci was the most common pathogen followed by K. pneumoniae and Enterobacter. Antibiogram showed that 15 of the 35 (43%) S. aureus identified were methicillin-resistant. Only 35-38 per cent of Enterobacteriaceae were sensitive to cefotaxime or ceftazidime. Cefoxitin was still effective against 95 per cent of K. pneumoniae. Compared with other third generation cephalosporins, combination of cefoperazone and betalactamase-inhibitor (sulbactam) possessed an increased in vitro efficacy against K. pneumoniae, Enterobacter, E. coli, Acinetobacter and non-fermentative gram-negative rods. Resistant rate of amikacin among all gram negative rods was 25-69 per cent. Ciprofloxacin sensitivity varied from 62-100 per cent among all gram-negative rods. Imipenem was excellent against all gram-negative rods with the sensitivity of 80-100 per cent. Epidemiological data of this study is important for the decision of the appropriate empirical antimicrobial treatment in our hospital.
