A Study Of Bacterial Infection Of Biliary Tract Operation In Geneal Surgery Department And The Susceptibility Of The Pathogenic Bacteria To Antibiotics

Followed the medical technology being changed with each passing day,the whole level of infectious prevention and cure has improved. However,the infection rate was still high. The perioperative infection during billiary tract operation seemed a big challenge for general surgery work due to multiple causes,in which it mainly resulted from the change of bacteria themselves,i.e. resistance of bacteria. This resistance to drugs was tightly related to the misuses of antibiotics. Till now,the mechanism of the resistance remained uncertain,so the study aimed it will provide us with a new approach for the infectious prevention and cure. To investigate the infectious conditions of billiary tract surgical operation in our hospital not only can help the clinical doctors have a relatively definite objective during the treatment of billiary tract infection,but also further the understanding about its new conditions recently. Moreover,by exploring the characteristics and susceptibility of these bacteria,we will have convincing evidence to choose the cheap but efficacious antibiotics for the patients. In this study,the bile was drawn from 226 patients with billiary tract operation and cultured for bacteria and tested for the susceptibility to antibiotics in our department from February to December in 2004. Result: Among the tested specimens,58 were found bacterial growth by culture,in which 19 were mixed infectious. 77 defined bacterial strains were identified from these specimens and they were Escherichia coli,Klebsiella,pseudomonas aerumginosa,enterococcus,Cit robacter,proteus,streptococcus viridans and staphylococcus,respectively by the order of positive rate. The positive rate of bacteria culture was significantly increased in the patients aged 60 or more or following the severe degree of disease.
