Risk factors of nosocomial infection after ventriculo-peritoneal shunt for hydrocephalus
OBJECTIVE To explore the related risk factors and pathogenic characteristics of nosocomial infection af-ter ventriculoperitoneal shunt.METHODS A total of 418 patients undergoing ventriculo-peritoneal shunt in the First Affiliated Hospital of Shandong First Medical University from Jan 2018 to Jun 2023 were enrolled for targe-ted monitoring.The demographic information and clinical data of patients were collected.Univariate and multivari-ate logistic regression analysis was used to analyze the risk factors for the infection.The distribution characteristics of pathogens was described.RESULTS Among 418 patients after ventriculoperitoneal shunt,47 patients were in-fected,with the infection rate of 11.24％.Multivariate logistic regression analysis showed that preoperative trach-eotomy,frontal angle puncture site,and higher surgical risk grade were risk factors for nosocomial infection in pa-tients undergoing ventriculoperitoneal shunt(P＜0.05).The main sites of nosocomial infection were respiratory system,surgical site and urinary system,accounting for 60.00％,16.37％and 12.73％respectively.CONCLUSION Preoperative tracheotomy,frontal puncture site,and higher surgical risk grade are high risk factors for infection after ventriculoperitoneal shunt.Targeted preventive measures should be taken into consideration.
