Summary
Severe fetal brain injury can occur without multiorgan system dysfunction (MSD). This study found 14 cases of hypoxic-ischemic encephalopathy (HIE) with permanent brain injury but no MSD, challenging previous understanding.
Area of Science:
- Perinatology
- Neonatology
- Neurology
Background:
- Intrapartum fetal asphyxial brain injury is typically associated with multiorgan system injury.
- Understanding the precise mechanisms of fetal brain injury is crucial for effective intervention.
Purpose of the Study:
- To describe cases of severe fetal brain injury without multiorgan system dysfunction (MSD).
- To investigate the underlying causes and clinical characteristics of such injuries.
Main Methods:
- Retrospective analysis of a national registry of brain-injured infants.
- Inclusion criteria: term, singleton infants with hypoxic-ischemic encephalopathy (HIE) and permanent central nervous system (CNS) injury.
- Exclusion criteria: infants meeting clinical criteria for MSD.
Main Results:
- 14 out of 292 infants (4.8%) with HIE and permanent neurologic injury had no MSD.
- The most common causes were uterine rupture (43%) and prolonged fetal heart rate (FHR) deceleration (36%).
- All affected infants were later diagnosed with cerebral palsy.
Conclusions:
- Severe fetal brain injury, particularly following prolonged FHR deceleration, can occur without evidence of MSD.
- This suggests that acute injuries may result from severely decreased cardiac output and hypotension, selectively affecting the brain before other organs.
