Catheter-related bloodstream infections in neonatal intensive care units

Area of Science:

• Neonatal intensive care
• Infectious diseases
• Medical devices

Background:

• Catheter-related bloodstream infections (CRBSIs) are a major concern in neonatal intensive care units (NICUs), impacting the survival of preterm infants.
• Central venous catheters (CVCs) are essential for managing critically ill neonates but pose a risk for CRBSI.
• CRBSI is defined by laboratory-confirmed bloodstream infection linked to CVC use, often caused by gram-positive bacteria.

Purpose of the Study:

• To review the incidence, risk factors, and prevention strategies for CRBSI in NICUs.
• To highlight the importance of standardized protocols for CVC insertion and maintenance.
• To emphasize the role of healthcare professional education in mitigating CRBSI.

Main Methods:

• Review of literature on CRBSI in neonatal populations.
• Analysis of common CVC types used in NICUs (umbilical venous, peripherally inserted central, tunneled).
• Identification of risk factors associated with CRBSI, including catheter dwell time and patient demographics.

Main Results:

• CRBSI remains a leading healthcare-associated infection in NICU settings, especially in preterm infants.
• Risk factors include prolonged catheter use, femoral access, low birth weight, and young gestational age.
• Variations exist in NICU protocols regarding disinfectants and skin care, despite a common goal to reduce CRBSI.

Conclusions:

• Implementing strict protocols for CVC placement and maintenance is crucial for reducing CRBSI rates.
• Comprehensive education for NICU physicians and nurses is essential for effective infection control.
• Standardized approaches to CVC care can significantly improve patient outcomes in the NICU.
