RESUMEN
Objective To explore the risk factors of surgical site infection(SSI)in patients undergoing selective brain tumor resection,and provide reference for clinical prevention and treatment.Methods Patients who under-went selective brain tumor resection in the neurosurgery department of a hospital during April-September 2013 and April-September 2014 were monitored prospectively,monitoring programme and individualized questionnaire were formulated,the basic data,operation condition,postoperative symptoms/signs,laboratory test results,infection-related factors,and antimicrobial use in patients were collected,risk factors for infection were analyzed.Results A total of 205 patients were investigated,23 (11 .22%)of whom had SSI;univariate analysis showed that body mass index (BMI),NNIS score,and cerebrospinal fluid leakage were related to the occurrence of SSI(all P<0.05);lo-gistic regression analysis showed that high NNIS score and cerebrospinal fluid leakage were independent risk factors for SSI in patients undergoing selective brain tumor resection(both P<0.05).Conclusion Incidence of SSI is high-er in patients with selective brain tumor resection,corresponding preventive measures should be taken according to different risk factors including cerebrospinal fluid leakage.
