Central Vein Preservation in Critical Venous Access

Area of Science:

• Pediatric Surgery
• Vascular Access
• Critical Care Medicine

Background:

• Central venous access is critical for children but challenging due to limited suitable veins.
• Traditional replacement methods involve removal, a "plastic-free" interval, and reinsertion, potentially impacting vein health.
• Vein-preserving (VP) techniques aim to mitigate these challenges.

Purpose of the Study:

• To evaluate the outcomes of vein-preserving (VP) central line replacement techniques, specifically sheath exchange for tunneled lines (SETL).
• To compare VP line exchanges with traditional "plastic-free" (PF) replacement periods in pediatric patients.

Main Methods:

• Retrospective analysis of prospectively maintained departmental logbook and patient medical records.
• Comparison of 19 directly exchanged VP lines with 34 lines inserted after a PF period.
• Analysis focused on catheter lifespan and infection rates.

Main Results:

• Catheter lifespan was similar between VP exchanges (125 days) and PF replacements (122 days) (p=0.41).
• Line sepsis rates were comparable, with removal/change occurring at 103 days for VP and 104 days for PF (p=0.73).
• No significant difference in outcomes was observed between the two groups.

Conclusions:

• Direct central line exchange procedures represent a robust and reproducible method for vein preservation in pediatric patients.
• VP techniques, such as SETL, provide comparable safety and efficacy to traditional PF replacement methods.
• These findings support VP techniques as a valuable strategy for managing critical venous access requirements in children.
