Timing of Focal Cerebral Injury in Pediatric Extracorporeal Life Support

Strategic Insights

— 1 min read

Research published in the journal Pediatric Critical Care Medicine reveals the timing of focal cerebral injury in relation to circuit interruptions in children and young adults. The study, conducted at the University of California San Francisco (UCSF), analyzed data from January 1, 2015, to December 31, 2023, and found that the majority of extracorporeal life support (ECLS)-related focal cerebral injuries (FCIs) were evident within 48 hours of ECLS cannulation, decannulation, or circuit interruption.

Key Takeaways:

  • The study analyzed 101 ECLS runs in 94 patients with brain imaging, of which 20 had focal cerebral injury (FCI).
  • FCI was radiographically defined as lateralized ischemia or hemorrhagic parenchymal brain injury greater than 1 cm3 or as subdural hemorrhage causing midline shift.
  • The presence of FCI vs. not was associated with lower survival to decannulation (p = 0.007).
  • Eighteen FCIs were documented within 48 hours of a circuit event, with eight of 13 FCIs with electroencephalography recording at the time of FCI having new-onset subclinical electroencephalography abnormality as the initial documented sign of FCI.
  • The study suggests that these events warrant increased surveillance for neurologic complications.

Statistics:

  • 20 out of 101 ECLS runs (20%) resulted in focal cerebral injury.
  • 18 out of 20 FCIs (90%) were documented within 48 hours of a circuit event.
  • 8 out of 13 FCIs (62%) with electroencephalography recording at the time of FCI had new-onset subclinical electroencephalography abnormality as the initial documented sign of FCI.
  • The presence of FCI was associated with lower survival to decannulation (p = 0.007).
