Objective  To investigate the categories and sensitivity of bacterial infection after pediatric living donor liver transplantation (LDLT).   Methods   Twenty two cases were operated for LDLT in our hospital from Jun 2006 to March 2009. Analyses were done retrospectively for the categories and sensitivity of bacterial infection after LDLT.   Results  Twenty cases among 22 (91%) had bacterial infections after LDLT. Respiratory tract (95%) and abdominal cavity (55%) were the most common system involved. Pseudomonas aeruginosa and Acinetobacter baumannii were most common in the infection of respiratory tract

while Staphylococcus epidermidis and Enterococcus faecium were responsible for infection of abdominal cavity. According to the sensitive test

Pseudomonas aeruginosa was sensitive to ciprofloxacin

levofloxacin

gatifloxacin and colistin; Acinetobacter baumannii was sensitive to imipenem

colistin and meropenem; Staphylococcus epidermidis and Enterococcus faecium infections were sensitive to vancomycin

linezolid and teicoplanin.   Conclusion  Bacterial infection is very common after pediatric LDLT

Pseudomonas aeruginosa

Staphylococcus epidermidis

Acinetobacter baumannii and Enterococcus faecium are the most common pathogens. Levofloxacin

imipenem and vancomycin can be used to treat Pseudomonas aeruginosa

Acinetobacter baumannii and Staphylococcus epidermidis/Enterococcus faecium infection respectively.
