使用 Hyperfine 进行 ECMO ABI 检测
低场床边 MRI 检测小儿体外膜氧合中的急性脑损伤
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.

详细说明
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.

武器和干预
参与者组/臂 |
干预/治疗 |
|---|---|
|
实验性的：Portable MRI Arm
All subjects enrolled will be assigned to Arm 1 |
Enrolled subjects will undergo a Hyperfine MRI exam, which is a portable, low-field MRI, at various timepoints during their clinical course on ECMO. Patients will undergo imaging within 36 hours of ECMO initiation/cannulation. Patients that remain on ECMO will have repeat imaging at 72-120 hours of ECMO therapy and again weekly for the duration of their ECMO course. Patients may also undergo a portable MRI within 24 hours of clinical head imaging, if applicable. |

Characterize the prevalence and type of ABI following cannulation for pediatric patients who require ECMO support.
大体时间：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 36 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). |

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. |

计划个人参与者数据 (IPD)
计划共享个人参与者数据 (IPD)？
IPD 计划说明
There is reasonable concern that sharing of IPD could allow patient re-identification given the single center study design involving a small and unique patient cohort. Given consideration for patient privacy, IPD will not be shared on open data platforms. De-identified IPD is available at reasonable request to the study PI with IRB approval and appropriate contracting.
