Pathogenic bacteria distribution in surgical site infection after spinal surgery and investigation of risk factors
Objective This paper aims to investigate the distribution of pathogenic bacteria and the risk factors of infection in spinal surgical site,so as to provide evidence for infection prevention and control measures.Methods Retrospective analysis was performed on the pathogenic bacteria detection results of postoperative incision infection in patients undergoing spinal surger-y in a hospital.Results A total of 2 148 spinal surgery patients were investigated,72 cases of postoperative incision infection were observed,and the infection rate was 3.35％.The incidence of spinal surgical site infections decreased from 4.38％in 2019 to 1.34％in 2022.A total of 78 strains of pathogenic bacteria were isolated from incision secretions,of which 66.67％were Gram-positive and 29.49％were Gram-negative.The top 3 pathogenic bacteria were Staphylococcus aureus,Staphylo-coccus epidermidis and Escherichia coli.The detection rate of methicillin-resistant Staphylococcus aureus(MRSA)was 21.74％,and that of methicillin-resistant Staphylococcus epidermidis was 60.00％.No vancomycin resistant strains was detec-ted.The resistance rate of Escherichia coli to imipenem was 0.00％.Multivariate analysis showed that diabetes,readmitted to hospital,alloblood transfusion and summer were independent risk factors for spinal surgical site infection(P＜0.05).Conclu-sion Staphylococcus aureus is the main pathogen of incision infection in spinal surgery,the risk factors of infection are clear,and targeted prevention and control measures can effectively prevent incision infection.
