Beskrivelse
Inclusion Criteria:
- No parental opposition to the use of the child's medical data within 1 month of the mailed information notice
- Gestational age ≥ 36 weeks of amenorrhea
- Birth weight ≥ 1800 g
- Born in a context of perinatal asphyxia (any cause) leading to suspected HIE, with EITHER biological signs of metabolic acidosis (pH ≤ 7 or base deficit ≥ 16 mmol/L or lactate ≥ 11 mmol/L within the first hour of life, any blood sample) OR a history of asphyxia with Apgar ≤ 5 at 10 minutes or need for ventilatory resuscitation continued at 10 minutes of life
- Non-compressed conventional EEG (EEGc) recorded before the 6th hour of life
- EEG including the signal of active electrodes Fp1, Fp2, T3 and T4
Exclusion Criteria:
- Participation in a therapeutic biomedical research liable to modify the EEG tracing
- Fewer than 20 minutes of artifact-free EEG recording
- Signal from active electrodes Fp1, Fp2, T3 and T4 not exploitable

Term newborns with suspected HIE
Single study population: term newborns (≥ 36 weeks, ≥ 1800 g) with suspected hypoxic-ischemic encephalopathy in a context of perinatal asphyxia, with an available non-compressed conventional EEG.
This is a diagnostic-accuracy validation study (STARD), not a comparative two-arm design.
The treated / untreated distinction is a pre-specified analysis subgroup only, not a study group.
