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.
