Insights
Brain injury in infants with congenital heart disease (CHD) after surgery is influenced by gestational age and postoperative infection. Improved brain function was linked to earlier gestational age and absence of infection.
Area of Science:
- Neonatal neurology
- Pediatric cardiology
- Neurocritical care
Background:
- Congenital heart disease (CHD) poses risks for infant brain injury.
- Cardiac surgery in infants with CHD requires careful monitoring for neurological complications.
- Amplitude-integrated electroencephalography (aEEG) is a valuable tool for assessing brain function in neonates.
Purpose of the Study:
- To identify factors influencing brain injury in infants with CHD post-cardiac surgery.
- To analyze the impact of gestational age and postoperative infection on neurological outcomes.
- To evaluate changes in brain activity patterns using aEEG.
Main Methods:
- Retrospective study of 103 infants with CHD undergoing cardiac surgery.
- Analysis of pre- and postoperative aEEG recordings for background pattern, sleep-wake cycle, and seizures.
- Logistic regression to determine factors associated with brain injury.
Main Results:
- Postoperative improvement in aEEG background patterns was significant in infants ≤39 weeks gestational age.
- Infants with postoperative sepsis or severe infection showed poorer sleep-wake cycle patterns.
- A significant improvement in brain function was observed post-surgery.
Conclusions:
- Gestational age and postoperative infection are key factors affecting brain function improvement in infants with CHD after cardiac surgery.
- Early detection and management of infection are crucial for better neurological outcomes.
- aEEG monitoring can help assess the impact of cardiac surgery on brain development.
Objective:
To identify the factors influencing brain injury in infants with congenital heart disease (CHD) after cardiac surgery.
Methods:
This retrospective study investigated 103 infants with CHD undergoing cardiac surgery between January 2013 and February 2016. Pre- and postoperative amplitude-integrated electroencephalography (aEEG) recordings were assessed for background pattern, sleep-wake cycle pattern and seizure activity. Logistic regression model was used to determine the influencing factors of brain injury.
Results:
Pre-operatively, most infants in our study exhibited a normal background pattern, with 16.5% showing discontinuous normal voltage, whereas this pattern was observed in only 7.8% of infants postoperatively. The improvement in background pattern after surgery was significant (P<0.05) in infants at no more than 39 weeks of gestational age. Infants with postoperative sepsis or severe postoperative infection were prone to show a worse sleep-wake cycle pattern after heart surgery.
Conclusions:
The improvement in brain function of infants with CHD after cardiac surgery was associated with the gestational age and postoperative infection.
