Practical approach to catheter-related bloodstream infections in paediatrics

Area of Science:

• Pediatric Infectious Diseases
• Medical Device Infections
• Clinical Microbiology

Background:

• Catheter-related bloodstream infections (CRBIs) represent a significant challenge in pediatric healthcare.
• The incidence and management of CRBIs are critical concerns for patient safety and clinical outcomes.

Purpose of the Study:

• To review and summarize current understanding and best practices regarding the prevention, diagnosis, and management of CRBIs in pediatric patients.
• To highlight key factors influencing CRBI rates and provide guidance on catheter management strategies.

Main Methods:

• Review of existing literature on pediatric CRBIs, focusing on prevention, diagnostics, and treatment guidelines.
• Analysis of diagnostic techniques, including comparative blood cultures and catheter cultures.
• Discussion of indications for catheter removal based on clinical presentation and microbial etiology.

Main Results:

• Sterile insertion techniques and meticulous catheter care are paramount in preventing CRBIs, often outweighing the impact of catheter material.
• Diagnostic accuracy for CRBIs can be enhanced through methods like comparing time to positivity in paired blood cultures or culturing the removed catheter.
• Catheter removal is indicated in specific scenarios, including hemodynamic instability, metastatic infection, tunnel infections, and infections caused by Candida or mycobacteria.

Conclusions:

• Emphasis on aseptic technique during insertion and maintenance is crucial for reducing pediatric CRBIs.
• Diagnostic strategies should be employed to confirm CRBIs accurately, guiding appropriate management.
• Catheter management decisions, including removal, should be individualized based on clinical context and causative pathogens, with specific considerations for Staphylococcus aureus and Gram-negative organisms.
