Insights
Amplitude-integrated electroencephalography (aEEG) effectively monitors brain function in preterm infants with asphyxia, aiding early diagnosis and prognosis. This method is crucial for improving outcomes and quality of life for these vulnerable infants.
Area of Science:
- Neonatal Neurology
- Neurophysiology
- Perinatal Medicine
Background:
- Preterm infant brain injury and associated risk factors require effective diagnostic tools for timely intervention.
- Hypoxic-ischemic encephalopathy (HIE) is a significant concern in preterm infants, impacting long-term neurological outcomes.
- Early detection and management of brain injury in preterm infants are critical for improving quality of life.
Purpose of the Study:
- To analyze the relationship between brain injury in preterm infants and risk factors.
- To evaluate the utility of amplitude-integrated electroencephalography (aEEG) in assessing brain function in preterm infants with asphyxia.
- To explore the potential of aEEG for early diagnosis and prognosis of HIE in preterm infants.
Main Methods:
- A case-control study involving preterm infants diagnosed with asphyxia and healthy term infants.
- Brain function monitoring using amplitude-integrated electroencephalography (aEEG) within 6 hours of birth.
- Analysis of aEEG parameters including background activity, sleep-wake cycles, and epileptic activity.
Main Results:
- aEEG provides valuable information on background brain activity, sleep-wake patterns, and epileptic activity in preterm infants.
- The aEEG findings correlate with the severity of HIE lesions and can predict long-term prognosis.
- aEEG is a user-friendly, effective, and continuously monitorable diagnostic tool for HIE.
Conclusions:
- Amplitude-integrated electroencephalography (aEEG) is a valuable tool for assessing brain injury in preterm infants with asphyxia.
- Combining aEEG with other biomarkers can enhance early HIE diagnosis and prognosis evaluation.
- Clinical popularization of aEEG is recommended for improved neonatal care and outcomes.
Abstract:
Analyzing and discussing the relationship between brain injury in preterm infants and related risk factors can provide evidence for perinatal prevention and early intervention of brain injury in preterm infants, thereby improving the quality of life of preterm infants. This paper selects term preterm infants diagnosed with preterm infant asphyxia in the NICU of a university's First Affiliated Hospital from January 2018 to February 2019 as the research object. In addition, healthy term infants born at the same time in the obstetric department of this hospital are selected as the control group. Both groups of premature infants were monitored for brain function within 6 hours after birth. The aEEG results range from background activity (continuous normal voltage, discontinuous normal voltage, burst suppression, continuous low voltage, and plateau) and sleep-wake cycle (no sleep-wake cycle, immature, and mature sleep-wake cycle) to epileptic activity (single seizures, recurrent seizures, and status epilepticus), three aspects to judge. Statistical analysis uses SPSS 17.0 software. Amplitude-integrated EEG is a simplified form of continuous EEG recording. The trace of the trace represents the voltage change signal of the entire EEG background activity, which can reflect the EEG amplitude, frequency, burst-inhibition, and other pieces of information. aEEG can reflect the degree of HIE lesions in premature infants and the long-term prognosis. It is easy to operate and effective in diagnosis and can be continuously monitored. It is worthy of clinical popularization. There is a good correlation between the expression of EEG and biomarkers. Combining multiple methods can diagnose HIE earlier and evaluate the prognosis.
