Abstract:
Objective To discuss drug resistance of wound-isolated pseudomonas aeruginosa and its correlation with use of antibiotics in children,for guiding the clinical use of antibiotics.Methods One hundred and forty wounded children admitted from January 2009 and December 2013 were collected in the study.There were 97 males and 43 females,aged (5.4 ± 2.6) years.All were victims of road traffic accidents.Distribution of bacteria isolated from the wound and drug resistance of pseudomonas aeruginosa were detected.Twenty-seven children with pseudomonas aeruginosa infection were divided into imipenem-resistant group (n =7) and non-imipenem resistant group (n =20).Drug resistance and application intensity of antibiotics were compared between the two groups.Results A total of 64 pathogens were isolated from the wound culture.Top five bacteria detected were acinetobacter baumannii,pseudomonas aeruginosa,enterobacter cloacae,escherichia coli and staphylococcus epidermidis.Pseudomonas aeruginosa showed resistance to β-lactam antibiotics,tetracyclines,chloram-phenicol and sulfanilamide.Drug resistance of piperacillin tazobactam (64.7％),meropenem (100％),ceftazidime (64.7％) and piperacillin (76.5％) in imipenem-resistant group were all 40％ higher than that in nonimipenem resistant group (P ＜ 0.05).Imipenem-resistant group versus non-imipenem resistant group revealed no significant differences in drug resistant rate of azactan (76.5％,39.0％),cefepime (70.6％,29.3％) and gentamicin (35.3％,17.1％) (P ＞ 0.05).There was no significant difference in total application intensity of antibiotics between the groups (P ＞ 0.05).Conclusions Wound-isolated pseudomonas aeruginosa in children is multidrug resistant.Thus bacterial monitoring in children with traumatic wounds should be strengthened and antibiotics should be selected rationally to reduce the production of multidrug resistance of pseudomonas aeruginosa.
