Olfactory testing to assess risk in newborns with birth asphyxia

Olfactory Memory in Infants With Signs of Asphyxia: An Early Indicator of Neurodevelopmental Outcomes

Observational University of Parma · NCT06744244

This study is testing if smelling different scents can help find newborns with mild to moderate birth asphyxia who might be at risk for serious brain problems.

What this trial studies

This observational study evaluates the olfactory function in term newborns who exhibit signs of mild to moderate birth asphyxia. By assessing olfactory memory through habituation to repeated odors, the study aims to identify newborns at high risk for hypoxic-ischemic encephalopathy, a severe neurological condition. The methodology includes olfactory testing alongside monitoring vital signs and neurodevelopmental assessments. Early identification of at-risk infants could facilitate timely interventions to improve their outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are term newborns (37-41 weeks gestational age) with signs of mild to moderate asphyxia at birth.

Not a fit: Patients who are preterm, post-term, or have significant congenital anomalies or genetic syndromes may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved early identification and intervention strategies for newborns at risk of neurodevelopmental disabilities due to birth asphyxia.

How similar studies have performed: While olfactory function has been studied in adults with neurological disorders, this approach in newborns with asphyxia is novel and has not been previously tested.
