Strategies to decrease the risk of ventricular catheter infections: a review of the evidence

Area of Science:

• Neurosurgery
• Infectious Disease Prevention
• Biomaterial Science

Background:

• External ventricular catheters (EVCs) are crucial for cerebrospinal fluid management.
• Catheter-associated infections pose significant clinical challenges.
• The efficacy of antibiotic coatings on EVCs remains debated.

Purpose of the Study:

• To systematically review in vivo and in vitro evidence supporting antibiotic-coated EVCs.
• To evaluate the effectiveness of antibiotic-coated catheters in preventing microbial adherence and infection.
• To inform the ongoing debate on the clinical utility of antibiotic-coated EVCs.

Main Methods:

• Comprehensive literature search for studies on antibiotic-coated EVCs.
• Inclusion of both laboratory (in vitro) and animal/patient (in vivo) research.
• Analysis of data regarding microbial colonization and clinical infection rates.

Main Results:

• Multiple studies demonstrate reduced microbial adherence to antibiotic-coated EVCs.
• Evidence suggests a potential benefit in preventing catheter colonization.
• Lack of consensus on standardized protocols for clinical application.

Conclusions:

• Antibiotic-coated EVCs show promise in reducing microbial adherence.
• Further research is needed to establish standardized clinical guidelines for their use.
• The debate on their universal adoption for infection prevention continues.
