Death after Birth Asphyxia in the Cooling Era

Area of Science:

• Neonatal Medicine
• Perinatal Care
• Medical Ethics

Background:

• Therapeutic hypothermia is a standard treatment for neonatal asphyxia.
• Infant instability can complicate hypothermia treatment.
• End-of-life decisions in neonates are ethically complex.

Purpose of the Study:

• To analyze mortality patterns in asphyxiated newborns treated with hypothermia.
• To identify factors associated with death during hypothermia therapy.
• To understand the role of palliative and ethics consultations in end-of-life care.

Main Methods:

• Retrospective analysis of asphyxiated newborn infants treated with hypothermia.
• Categorization of deaths based on timing relative to hypothermia completion.
• Review of consultations with palliative care and clinical ethics services.

Main Results:

• 62% of deaths (31/50) occurred in infants electively extubated before completing hypothermia.
• Later deaths were associated with palliative care (13/19) or ethics (6/19) consultations.
• Withdrawal of nutrition and hydration was a factor in 4 cases.

Conclusions:

• Early extubation in unstable infants is linked to increased mortality during hypothermia.
• Palliative and ethics consultations are crucial for managing challenging end-of-life decisions.
• Support is needed for decisions involving withdrawal of care, including nutrition and hydration.
