Insights

Delirium is common in critically ill children with COVID-19, particularly those on invasive mechanical ventilation. Focus on developmental disability and minimizing risks during ventilation for delirium reduction.

Area of Science:

  • Pediatric critical care medicine
  • Infectious diseases
  • Neuroscience

Background:

  • Delirium is under-recognized in critically ill children.
  • COVID-19 is associated with delirium in adults, but pediatric data are lacking.
  • Multisystem inflammatory syndrome in children (MIS-C) involves hyperinflammation, potentially increasing delirium risk.

Purpose of the Study:

  • To characterize delirium in critically ill children with COVID-19.
  • To investigate demographic, disease, and treatment factors associated with pediatric delirium.
  • To test the hypothesis that MIS-C is linked to higher delirium incidence.

Main Methods:

  • Retrospective, single-center cohort study.
  • Included 149 pediatric intensive care unit (PICU) hospitalizations with SARS-CoV-2 infection (March 2020-March 2023).
  • Categorized patients by COVID-19 respiratory disease, MIS-C, or other primary reasons; assessed delirium incidence and risk factors.

Main Results:

  • Delirium occurred in 43% of patients; highest incidence in those requiring invasive mechanical ventilation (IMV) (56%).
  • Opioid, dexmedetomidine, paralytic, and benzodiazepine exposure correlated with delirium.
  • Multivariable analysis linked delirium to IMV, female sex, and developmental disability.

Conclusions:

  • Delirium is prevalent in pediatric COVID-19 patients, though less common than in adults.
  • Delirium reduction strategies should target children with developmental disabilities.
  • Minimizing risks associated with IMV is crucial for preventing delirium in this population.
