Clinical Scorecard: Assessment of Initial Arterial Blood Gas Metrics, Clinical Characteristics, and Neuroimaging Results in Neonates Treated with Therapeutic Hypothermia for Suspected Hypoxic-Ischemic Encephalopathy: A Retrospective Analysis from a Single Center

At a Glance

Key Highlights

• 72.7% of neonates showed no final evidence of HIE.
• Lower bicarbonate levels were associated with the presence of any-stage HIE.
• Seizures correlated with lower gestational age and more negative base excess values.
• Concordance between cranial ultrasonography and MRI was low.
• MRI findings were more sensitive in detecting brain injury compared to ultrasonography.

Guideline-Based Recommendations

Diagnosis

• Final HIE classification should be based on clinical course, seizures, neurologic findings, EEG data, and neuroimaging.

Management

• Therapeutic hypothermia is recommended for term and near-term neonates with moderate to severe HIE.

Monitoring & Follow-up

• Early blood gas parameters should be monitored to assess perinatal acid-base status and severity of hypoxic-ischemic insult.

Risks

• Abnormal MRI patterns are associated with adverse neurodevelopmental outcomes.

Patient & Prescribing Data

Neonates treated with therapeutic hypothermia for suspected HIE.

Bicarbonate levels and blood gas parameters are critical for assessing HIE severity.

Clinical Best Practices

• Utilize MRI for confirming the pattern and severity of hypoxic-ischemic injury.
• Consider the discordance between cranial ultrasonography and MRI in clinical assessments.
