Pathogenic Organism of Surgical Cut Infection and Germiculture Result from Incisal Margin Swab / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To understand the situation of pathogenic organism of surgical cut infection and germiculture result from incisal margin swab,analyze the characteristic of pathogenic organism,and provide the measures to control.METHODS To investigate the patients from Jun 2004 to Sep 2005,and analyze the data of pathogenic organism of surgical cut infection and germiculture result from incisal margin swab.RESULTS From 10278 surgical cases 124 cases(1.29%) were with surgical cut infection,From 94 samples of incisal margin swabs 58(61.70%) were positive with 59 bacterial strains,including 32(54.24%) Escherichia coli isolates,10(16.95%) of coagulase negative Staphylococcus(CNS),3(5.08%) Klebsiella pneumoniae isolates and 3(5.08%) Streptococcus intermedius isolates.From 118 samples of surgical cut infection cases 102(86.44%) were positive with 120 strains,including 49(40.38%) E.coli isolates,25(20.83%) of CNS,and 7(5.83%) K.pneumoniae isolates.CONCLUSIONS The main bacteria of type Ⅰ surgical cut infection are Staphylococcus and that of types Ⅱ and Ⅲ surgical cut infection are E.coli.The rusults from incisal margin swabs have the important value to the treatment of surgical cut infection to guide the antibiotic use reasonably.
