Study Notes
Hypoxic Ischaemic Encephalopathy (HIE)
- Occurs due to reduced uteroplacental blood flow or interference with spontaneous respiration, leading to perinatal hypoxia and ischaemia
- Can lead to spastic quadriplegia or diplegia and mental retardation
Clinical Manifestations of HIE
- Severity of injury determines clinical manifestations
Grading of HIE
Grade I HIE
- Alternating periods of lethargy and irritability, hyper-alertness, and jitteriness

- Exaggerated and/or spontaneous Moro reflex
- Increased heart rate and dilated pupils
- No seizure activity
- Symptoms resolve within 24 hours
Grade II HIE
- Lethargy
- Poor feeding and depressed gag reflex
- Hypotonia
- Low heart rate and papillary constriction
- 50-70% of infants display seizures, usually within the first 24 hours after birth
- Oliguria
- Symptoms last from 24 hours to 14 days
Grade III HIE
- Coma
- Flaccidity
- Absent reflexes
