Brief Summary

The primary objective is to characterize the prevalence and type of ABI following cannulation for pediatric patients who require ECMO support. The secondary objective is to describe the time course and rates of ABI using ultralow-field bedside MRI relative to both duration of ECMO support and clinical imaging obtained in routine care of pediatric ECMO patients.

Detailed Description

Extracorporeal membrane oxygenation (ECMO) is frequently used to treat refractory cardiovascular and/or respiratory failure. As the support modality has evolved, survival has significantly improved, yet there are high rates of acute brain injury (ABI) in this population due to disease, patient, and treatment factors. This results in significant morbidity and mortality. Specifically, thromboembolic, hypoxic-ischemic, and hemorrhagic complications occur during ECMO support, but the investigators are limited in the monitoring and diagnosis of ABI while on ECMO as currently available imaging modalities (i.e. ultrasound \[US\], computed tomography \[CT\]) have low sensitivity for early hypoxic, cerebrovascular, and ischemic brain injuries. The sensitivity of these modalities increases only when it is too late to effectively intervene. Standard magnetic resonance imaging (MRI) is the gold standard to diagnose stroke and ischemic brain injury but is incompatible with ECMO devices. Swoop (Hyperfine, Guilford, CT) is an FDA cleared ultralow-field portable MRI system that can be used at the bedside and has been studied in critically ill adults with various types of ABI. This novel bedside MRI has been safely operated in clinical environments with equipment that is typically not MRI compatible. A few adult and pediatric ECMO patients have undergone bedside brain MRIs showing feasibility. Yet, what remains unknown is the true prevalence and timing of hypoxic, cerebrovascular, and ischemic brain injuries in pediatric ECMO.

Primary Outcome Measures
NameTimeMethod
Characterize the prevalence and type of ABI following cannulation for pediatric patients who require ECMO support.Duration of ECMO treatment period, an average of <2 weeks

Perform bedside MRI in pediatric ECMO patients treated in pediatric, cardiac, and neonatal intensive care units (ICUs) within 24 hours of cannulation. Determine rates of ABI (hypoxic, ischemic, cerebrovascular, and hemorrhagic injury along with assessment of cerebral edema and midline shift) in the pre- and peri-cannulation time periods. Correlate these imaging findings to rates of clinical neurological events (seizures, pupillary changes, focal neurological examination).

Secondary Outcome Measures
NameTimeMethod
Describe the time course and rates of ABI using ultralow-field bedside MRI relative to both duration of ECMO support and clinical imaging obtained in routine care of pediatric ECMO patients.Duration of ECMO treatment period, an average of <2 weeks

Obtain bedside MRI in pediatric ECMO patients treated in pediatric, cardiac or neonatal ICUs at 72-120 hours post-cannulation and weekly until decannulation. Quantify and compare rates of ABI between bedside MRI and CT or US as read by blinded neuroradiologist.
