Page 2: 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

Introduction

Page 3: Introduction

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

Aim

Page 4: Introduction

Between January 2008 January 2008 and December 2011December 2011 58 58 patients with acute hydrocephalus of

various reasons were respectively reviewed. Exclusion criteria Exclusion criteria were

removal of EVD <24 hoursEVD <24 hours, suspected infection suspected infection before insertion of the

catheter and former EVD insertion former EVD insertion within the previous 30

days.

Material and Methods

Page 5: Introduction

The study group with silver-bearing EVDs silver-bearing EVDs consisted of 26 patients 26 patients and

The control group with standard EVD The control group with standard EVD catheters consisted of 32 patients32 patients.

After removal of the catheters, they were also assessed microbiologically for colonization of the catheter’s tip.

Material and Methods

Page 6: Introduction

Positive CSF culture or colonization of the catheter tip was found in

6 cases with silver-bearing EVDs (23,7%),6 cases with silver-bearing EVDs (23,7%), 10 cases in the control group (31,3%).10 cases in the control group (31,3%).

Results

Page 7: Introduction

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