Central line placement at ECMO decannulation: A missed opportunity

Area of Science:

• Pediatric critical care medicine
• Vascular access management
• Extracorporeal life support

Background:

• Extracorporeal membrane oxygenation (ECMO) provides life support for critically ill patients.
• Central venous lines (CVLs) are essential for managing complex pediatric critical illnesses.
• This study examines the practice of placing CVLs during pediatric ECMO decannulation.

Purpose of the Study:

• To determine the incidence of central venous line (CVL) placement at pediatric ECMO decannulation.
• To evaluate the utility and outcomes of CVLs placed during this procedure.
• To assess the need for CVLs in patients not receiving them at decannulation.

Main Methods:

• Retrospective review of pediatric patients undergoing open neck ECMO decannulation (2015-2019).
• Patients categorized into two groups: ≤28 days (neonates) and >28 days (older children).
• Analysis of CVL indications, functionality, and subsequent need for vascular access.

Main Results:

• 31% of 65 patients had a CVL placed at decannulation.
• Indications varied by age: hemodialysis in older children, access in neonates.
• 40% of patients without a CVL at decannulation required one within 30 days; most placed lines were functional.

Conclusions:

• A significant proportion of pediatric ECMO decannulations do not involve CVL placement, yet many patients subsequently require one.
• Placing essential CVLs during decannulation can be a safe and effective strategy for vascular access.
• Optimizing CVL placement at decannulation can improve patient management and reduce the need for emergent access later.
