Risk factors for recurrent shunt infections in children

摘要

Risk factors for recurrent shunt-related cerebrospinal fluid (CSF) infections were analyzed. A total of 58 children were treated for initial shunt infections (ISI): all children were treated with antibiotics and CSF drainage, either by removal of the shunt system and insertion of an external ventricular drainage (EVD) catheter (44 children, 75.9%) or by externalization of the existing ventricular catheter (14 children, 24.1%). Recurrent shunt infections (RSI) were detected in 15 children: nine had been treated with shunt removal and insertion of a new EVD catheter and six had been treated with externalization of the existing ventricular catheter. There was a statistically significant increase in the number of RSI in children treated with externalization of the existing ventricular catheter. Thus, to reduce the risk of RSI, total shunt removal and insertion of a new EVD catheter is preferred.
