Outcome in relation to Apgar score in term neonates

Area of Science:

• Neonatalogy
• Perinatal Medicine
• Pediatric Neurology

Background:

• Birth asphyxia is a significant cause of neonatal mortality and morbidity.
• Apgar scores are routinely used to assess a newborn's condition at birth.
• The prognostic value of Apgar scores, especially at later time points, requires further clarification.

Purpose of the Study:

• To evaluate the correlation between Apgar scores at 5 and 10 minutes and neurodevelopmental outcomes in asphyxiated term neonates.
• To compare the outcomes of asphyxiated neonates with different Apgar score timings and severity.
• To determine the threshold Apgar score indicative of outcomes similar to non-asphyxiated controls.

Main Methods:

• A cohort study comparing 64 asphyxiated term neonates with 90 non-asphyxiated term controls.
• Follow-up assessment of mortality and neurodevelopmental outcomes in 40 cases and 48 controls.
• Analysis of Apgar scores at 5 and 10 minutes and their correlation with clinical outcomes.

Main Results:

• Mortality and poor neurodevelopmental outcomes showed an inverse correlation with Apgar scores at 5 and 10 minutes.
• Neonates with low 5-minute Apgar scores had a significantly better outcome than those with similar scores at 10 minutes.
• Symptomatic neonates with identical Apgar scores exhibited poorer outcomes compared to asymptomatic neonates.

Conclusions:

• Apgar scores at 5 and 10 minutes are valuable predictors of mortality and neurodevelopmental outcomes in term neonates.
• The timing of the Apgar score is critical, with 5-minute scores offering a more optimistic prognosis than 10-minute scores for similar values.
• Term neonates with Apgar scores of 6 at 5 or 10 minutes demonstrate outcomes comparable to non-asphyxiated controls, suggesting resilience at this score level.
