Correlation Factor And Investigate Of Infectious Epidemiology And Postoperative Infection In Department Of Orthopedics

Objective: To analyze the related factor of surgical site infection in patients with orthopedic surgery and prevent the infection rate.Methods A total of 14300 patients with orthopedic surgery in our hospital from 2010 to 2014 were retrospectively analyzed. The condition and clinical symptoms of the patients were analyzed and bacteriological analysis were performed, then the potential risk factors of surgical site infection in patients were analyzed by univariate analysis and logistic regressionResults: Of the 14300 patients, infection occurred in 576 cases and the rate of surgical site infection was 4.03%. The rate of type I, type II, type III incision infection were respectively2.42%, 7.20%, 14.85%, showing an upward trend. However the amputation surgery infection rate was the highest up to 22.67%. Totally 615 strains of pathogenic bacteria have been isolated, including 357(58.04%)Gram-negative strains, 235(38.21%)Gram positive strains,23(3.74%)fungus; the Staphylococcus aureus, Escherichia coli, Enterobacter cloacae ranked the top three species of pathogens. The multivariate logistic regression analysis indicated that the age, operation time, intraoperative blood loss, length of incision, incision type, anesthesia type, postoperative suction drainage, hospital stays, operative types, underlying disease and perioperative antibiotic use were the independent risk factors for the incision infections.Conclusion: The rate of SSI of orthopedics is relatively high, and it remains necessary to take corresponding intervention measure to the related risk factors of the incisions in order to further the infections.
