Pediatric and neonatal extracorporeal life support: current state and continuing evolution

Brian P Fallon et al. Pediatr Surg Int. 2021 Jan.

Abstract

The use of extracorporeal life support (ECLS) for the pediatric and neonatal population continues to grow. At the same time, there have been dramatic improvements in the technology and safety of ECLS that have broadened the scope of its application. This article will review the evolving landscape of ECLS, including its expanding indications and shrinking contraindications. It will also describe traditional and hybrid cannulation strategies as well as changes in circuit components such as servo regulation, non-thrombogenic surfaces, and paracorporeal lung-assist devices. Finally, it will outline the modern approach to managing a patient on ECLS, including anticoagulation, sedation, rehabilitation, nutrition, and staffing.

Keywords: Extracorporeal life support (ECLS); Extracorporeal membrane oxygenation (ECMO); Neonatal; Pediatric; Respiratory failure.

Red lines depict the blood flow pattern. Solid yellow lines depict concentric gates. Key features of the MLung include: (1) Blood inlets; (2) outer fiber bundle; (3) inner fiber bundle; (4) blood outlet; c Pediatric MLung empty housing (left) and housing with fiber bundle installed (right); d. MLung in vivo immediately after cannulation and connection. Key features of the circuit include: (1) inlet cannula (from PA); (2) MLung; (3) outlet cannula (to LA); (4) sweep gas inlet; (5) gas outlet with suction tubing. b Reproduced with permission from Thompson et al.
