Multi-Organ Dysfunction in Neonatal Hypoxic Ischemic Encephalopathy and Brain Magnetic Resonance Imaging Outcomes

Area of Science:

• Neonatal Neurology
• Pediatric Cardiology
• Neonatal Intensive Care

Background:

• Hypoxic-ischemic encephalopathy (HIE) in neonates often leads to multi-organ dysfunction (MOD).
• Evaluating the link between MOD and HIE-related brain MRI findings in neonates undergoing therapeutic hypothermia is crucial.

Purpose of the Study:

• To assess the association between multi-organ dysfunction (MOD) and hypoxic-ischemic encephalopathy (HIE)-related brain MRI findings in neonates receiving therapeutic hypothermia.
• To determine if the severity or number of organ system involvements predicts HIE-related MRI abnormalities.

Main Methods:

• Retrospective cohort study of neonates with encephalopathy who received therapeutic hypothermia.
• Classification of neonates based on normal or HIE-related changes on brain MRI.
• Assessment of multi-organ dysfunction (MOD) based on organ system involvement.

Main Results:

• 40% of neonates showed HIE-related MRI findings; 56% had MOD.
• Neonates with HIE MRI changes were more likely to have MOD (74% vs. 45%).
• Increased organ dysfunctions correlated with higher odds of abnormal brain MRI, particularly with severe neurological or cardiac dysfunction.

Conclusions:

• A higher number of organ dysfunctions in neonates undergoing therapeutic hypothermia is associated with HIE-related brain MRI changes.
• Severe neurological dysfunction and cardiac dysfunction present the highest risk for HIE-related MRI findings.
