The Apgar score is not a reliable indicator for diagnosing newborn asphyxia. Low one-minute Apgar scores lack the sensitivity to confirm asphyxia, necessitating caution when using this score alone.

Area of Science:

  • Neonatal Medicine
  • Pediatric Diagnostics
  • Clinical Evaluation

Background:

  • The Apgar score is a standard assessment for newborns.
  • Its utility in diagnosing asphyxia remains a subject of clinical debate.
  • Accurate diagnosis of birth asphyxia is critical for timely intervention.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of the Apgar score for identifying neonatal asphyxia.
  • To determine the sensitivity, specificity, and predictive values of Apgar scores.
  • To provide evidence-based recommendations on using Apgar scores in relation to asphyxia.

Main Methods:

  • Systematic literature review of studies assessing Apgar scores and asphyxia.
  • Analysis of diagnostic test performance metrics (sensitivity, specificity, predictive values).

  • Comparison of Apgar scores with umbilical cord arterial pH < 7.2 as the gold standard for asphyxia.

    • Main Results:

    • The one-minute Apgar score demonstrated poor sensitivity as a marker for asphyxia.
    • Diagnostic accuracy metrics indicate limitations in Apgar's predictive capability for asphyxia.
    • Umbilical cord arterial pH below 7.2 served as the reference standard for asphyxia.

    Conclusions:

    • The Apgar score, particularly at one minute, is insufficient for diagnosing neonatal asphyxia.
    • Clinicians should avoid using the term "asphyxia" based solely on Apgar score results.
    • Further research may be needed to identify more accurate early diagnostic markers for birth asphyxia.
