How frequently external ventricular drainage device should be changed in children with ventriculoperitonel shunt...

Area of Science:

• Pediatric Neurosurgery
• Infectious Diseases
• Medical Device Management

Background:

• Ventriculoperitoneal shunt (VPS) infections are serious complications in pediatric neurosurgery.
• External ventricular drainage (EVD) is often required for managing hydrocephalus and infection.
• Optimizing EVD management is crucial for effective antimicrobial therapy and patient outcomes.

Purpose of the Study:

• To determine the optimal frequency for changing external ventricular drainage (EVD) devices in children with ventriculoperitoneal shunt (VPS) infection.
• To evaluate the impact of EVD replacement frequency on infection resolution during intravenous antimicrobial therapy.

Main Methods:

• Retrospective analysis of 25 pediatric patients with VPS infection treated between January 2012 and December 2013.
• Evaluation of EVD replacement frequency, cerebrospinal fluid (CSF) analysis (cell count, glucose, protein), and CSF culture results.
• Correlation of EVD dwell time with daily changes in CSF leukocyte count.

Main Results:

• The study included 25 children, with a median age of three months.
• Staphylococcus epidermidis was the most common pathogen (44%).
• Children whose EVD catheters remained in place for less than 10 days showed a faster daily decrease in CSF leukocyte count (5 units/day) compared to those with catheters for over 10 days (2.21 units/day).

Conclusions:

• Changing the external ventricular drainage (EVD) device every 10 days is recommended for children with ventriculoperitoneal shunt (VPS) infection.
• This EVD replacement frequency facilitates more rapid resolution of infection, as indicated by faster normalization of CSF inflammatory markers.
• The findings provide evidence-based guidance for managing EVD in pediatric neurosurgical infections.
