Practice patterns for acquiring neuroimaging after pediatric in-hospital cardiac arrest
Authors' conclusion
Practice patterns for acquiring neuroimaging after IHCA are variable and influenced by patient, cardiac arrest, and site factors.
Study context
- Population
- Children who survived in-hospital cardiac arrest (IHCA), enrolled in the ICU-RESUS trial
- Participants
- 1,000 children
- Outcome
- Factors associated with obtaining neuroimaging (US, CT, MRI) after IHCA, and with modality obtained
- Follow-up
- Within 7 days following IHCA
Methodological detailssecondary analysis of ICU-RESUS trial cohort, multivariable models
- Secondary analysis of ICU-RESUS trial cohort
- Multivariable models
Main finding
As reported in the abstract
Neuroimaging frequency within 7 days post-IHCA · within 7 days
≥ 1 neuroimaging study
44%
Ultrasound (US)
31%
CT
18%
MRI
6%
Observational data: associations, not effects.
Further findings
Time to initial neuroimaging (days post-arrest)
Factors associated with modality
- US associated with congenital heart disease
- CT associated with age ≥ 1-month, greater pre-arrest disability, CPR ≥ 16 min
- MRI increased with pre-existing respiratory insufficiency, respiratory decompensation as arrest cause, and medical cardiac and surgical non-cardiac or trauma illness category
- If neuroimaging obtained, US more common in CICU; CT/MRI more in PICU
