Analysis of pathogenic characteristics of incision infection after closed fracture / 中国基层医药

ABSTRACT

Objective@#To investigate the etiological characteristics of incision infection after closed fracture surgery.@*Methods@#From January 2012 to December 2017, 20 closed fracture patients with postoperative incision infection in Lanxi Ruikang Hospital were selected in the research.The wound infection and secretion samples after closed fracture surgery were collected for isolation and identification of pathogenic bacteria and drug sensitivity test.@*Results@#A total of 33 strains of pathogenic bacteria were isolated and cultured in 20 cases of wound infection after closed fracture operation, including 21 Gram-negative bacteria, 11 Gram-positive bacteria and 1 fungi.Among Gram-negative bacteria, 8 strains of Pseudomonas aeruginosa and 6 strains of Escherichia coli were found.Among Gram-positive bacteria, 6 strains of Staphylococcus aureus were found.The resistance rates of Pseudomonas aeruginosa to ceftriaxone, ceftazidime and cefoperazone were 87.50%, 87.50% and 75.00%, respectively, and the resistance rates of Escherichia coli to ceftriaxone and ceftazidime were 100.00% and 83.33%, respectively.The resistance rates of Staphylococcus aureus to penicillin G and erythromycin were 100.00% and 83.33%, respectively.@*Conclusion@#The pathogenic bacteria of closed fracture postoperative incision infection are Gram-negative bacteria, three pathogenic bacteria were Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli, the drug resistance rate of Gram negative bacteria to cephalosporin is high, the resistance rate of main Gram positive bacteria to penicillin and erythromycin G is high.
