Analysis Of The Risk Factors And Treatment Strategies Of The Posterior Spinal Postsurgical Infection

Objective:To investigate the risk factors and treatment strategies of the posterior spinal postoperative infection.Methods:A retrospective analysis including 857 cases of posterior spinal surgery patients from September 2012 to September 2013 was performed in our hospital, they were divided into infected and non-infected group. There were 34 infection cases, including 22 males and 12 females, aged 12-76 years, with mean age of 47.1 years; and there were 823 non-infection cases, including 465 male and 358 female, aged 2.7-81 years, with mean age of 46.5 years. We compared the preoperative, intraoperative, postoperative factors affecting postoperative infection in two groups of patients, through the analysis of the treatment and the therapeutic effect of 34 patients, we summed up better therapeutic strategies.Results:The posterior spinal postsurgical incision infection rate was 3.97%(34/857), in this research, muscle strength≤3 level, preoperative immune dysfunction, acute or chronic infection, previous spine surgery history, preoperative and postoperative incontinence or catheterization time≥3 days, obesity, operative time≥180min, Intraoperative bleeding≤600ml, blood transfusions, allogeneic bone grafting antibiotics, Preoperative or postoperative incontinence or catheterization time≤3 days, after surgery into ICU, the number of drainage pipes, the time of indwelling drainage tube Etc. there existed statistical significant difference, P<0.05, other variables showed no statistical significance. Logistic regression analysis after acute or chronic infections, obesity (BMI> 30kg/m2), transferred to ICU after surgery these three factors(OR>1,P <0.05)are the independent risk factors for postoperative infection.Conclusion:Acute or chronic infections, obesity (BMI> 30kg/m2), transferred to ICU after surgery, these three factors listed are the independent risk factors for postoperative infection. We need to prevent these three risk factors and other factors that may affect the postoperative infection, and different uses of spinal infection should be treated in different ways. It is even more important to choose the appropriate treatment.
