Diagnosing brain death in newborns is possible, even in those under 7 days old. A 48-hour observation period is standard, potentially shortened with specific tests, with a low risk of misdiagnosis.

Area of Science:

  • Neonatal neurology
  • Pediatric critical care

Background:

  • Establishing brain death criteria in neonates is crucial for clinical management and ethical decision-making.
  • Previous guidelines have varied, necessitating clear diagnostic protocols for this vulnerable population.

Purpose of the Study:

  • To define the diagnostic criteria and observation periods for brain death in full-term newborns.
  • To assess the reliability and safety of these criteria in clinical practice.

Main Methods:

  • Review of existing literature and clinical data on neonatal brain death diagnosis.
  • Analysis of observation periods and confirmatory tests, including electroencephalography (EEG) and cerebral blood flow (CBF) studies.

Main Results:

  • Brain death diagnosis is feasible in newborns less than 7 days old, with a recommended 48-hour observation period.

  • This period can be reduced to 24 hours if an isoelectric EEG or absent CBF is documented.
  • The risk of misdiagnosis is exceedingly low, with rare instances of transient recovery not indicating meaningful neurologic function.

    • Conclusions:

    • The established criteria and observation periods are reliable for diagnosing brain death in neonates.
    • These guidelines support timely and accurate clinical decision-making in neonatal critical care settings.
