Hypoxia patterns in full-term newborns with very low umbilical cord pH
Hypoxia Profiles Identified in Term Newborns With Cord pH <7.00
This project tries to see if there are distinct hypoxia patterns and fetal heart-rate signs in full-term newborns whose umbilical cord arterial pH is below 7.00.

What this trial studies
Researchers will perform a retrospective observational analysis of term singleton deliveries at Strasbourg University Hospital from January 1, 2014 to December 31, 2024, selecting infants with cord arterial pH <7.00. They will review cardiotocography (CTG) tracings, delivery records, and neonatal outcomes to identify profiles of hypoxia and timing relationships with clinical events. The focus is on characterizing fetal heart-rate changes and patterns associated with severe acidosis rather than testing an intervention. The analysis excludes preterm births, known congenital malformations, intrauterine fetal death on admission, and cases without CTG recordings.
Who should consider this trial
Good fit: Ideal candidates are adult women (≥18 years) who delivered a singleton at term at Strasbourg University Hospital between 2014 and 2024 whose infants had an arterial cord pH below 7.00 and who have available CTG recordings.
Not a fit: Patients who are preterm (<37 weeks), have known congenital malformations, had intrauterine fetal death on admission, lack CTG recordings, or delivered outside the specified hospital or timeframe are unlikely to be included or to benefit.
Why it matters
Potential benefit: If successful, the findings could help clinicians recognize dangerous intrapartum hypoxia earlier, reduce delayed diagnoses and unnecessary obstetric interventions, and improve newborn neurological outcomes.
How similar studies have performed: Previous research linking fetal heart rate patterns to neonatal acidemia has shown mixed results with persistent inter-observer variability, so this work builds on existing but not definitive evidence.
