REDUCTION OF INFECTIONS AFTER USING
SILVER-BEARING EXTERNAL VENTRICULAR CATHETERS A
RETROSPECTIVE STUDY

Introduction
  • The insertion of an external ventricular drainage
    (EVD) for the treatment of acute hydrocephalus is
    one of the most commonly performed procedures in
    neurosurgery.
  • EVD-related infections may lead to further
    serious complications such as ventriculitis,
    meningitis and brain abscess

3
Aim
  • The aim of this article is to compare the
    efficacy of silver-bearing EVD catheters for
    reducing the incidence of infection with standard
    nonimpregnated EVD catheters in neurosurgical
    patients.

4
Material and Methods
  • Between January 2008 and December 2011
  • 58 patients with acute hydrocephalus of various
    reasons were respectively reviewed.
  • Exclusion criteria were
  • removal of EVD lt24 hours,
  • suspected infection before insertion of the
    catheter and
  • former EVD insertion within the previous 30 days.

5
Material and Methods
  • The study group with silver-bearing EVDs
    consisted of 26 patients and
  • The control group with standard EVD catheters
    consisted of 32 patients.
  • After removal of the catheters, they were also
    assessed microbiologically for colonization of
    the catheters tip.

6
Results
  • Positive CSF culture or colonization of the
    catheter tip was found in
  • 6 cases with silver-bearing EVDs (23,7),
  • 10 cases in the control group (31,3).

7
Discussion
  • Although the size of the sample is limited, this
    analysis indicates that silver-bearing EVD
    catheters are accompanied with smaller rates of
    infection in neurosurgical patients, when
    compared with standard EVDs
