Study Notes
Perinatal Asphyxia
- Diagnostic criteria for perinatal asphyxia include a lack of breathing, a slow heart rate, and a low Apgar score at birth.
- Additionally, presence of fetal distress, meconium-stained amniotic fluid, and umbilical artery acidosis are also considered diagnostic criteria.
Mortality Rate
- Moderate or severe hypoxic-ischemic encephalopathy (HIE) results in death for approximately 20-50% of affected infants.
Hypoxia
- Hypoxia is defined as a state of inadequate oxygen supply to the body's tissues.
Apgar Score
- Apgar score assesses the newborn's overall health and vitality at one and five minutes after birth, taking into account heart rate, breathing, muscle tone, reflexes, and color.
Impact on Survivors
- Survivors of perinatal asphyxia are at risk of developing long-term neurological and cognitive impairments, including cerebral palsy, epilepsy, and learning disabilities.
- Additionally, survivors may experience developmental delays, motor impairments, and vision or hearing problems.
