Study Notes

Perinatal Asphyxia

  • Perinatal asphyxia is a condition in which a newborn infant experiences inadequate oxygenation and ventilation, leading to a lack of oxygen in the brain and other organs.

Characteristics and Occurrence

  • According to the World Health Organization (WHO), a characteristic of perinatal asphyxia is a delay in the onset of breathing in the first minute of life.
  • Perinatal asphyxia occurs when a newborn infant fails to initiate and sustain breathing at birth, resulting in a lack of oxygen supply to the brain and other organs.

Organ Damage

  • The most concerning organ for hypoxic damage in perinatal asphyxia is the brain, as it is highly sensitive to oxygen deprivation.

Immediate Requirement

  • The immediate requirement for perinatal asphyxia is assisted ventilation, which should be initiated within the first minute of life to prevent long-term brain damage and other complications.
