CLINICAL APPLICATION OF BRAIN FUNCTION MONITORING

SCREENING

• Screening neonates at risk of neonatal hypoxic ischemic encephalopathy(HIE), septicemia of preterm infants (SIE), asphyxia,epilepsy,convulsions,intracranial hemorrhage and hydrocephalus.

MONITORING

• Real-time monitoring of the dynamic changes in the neonatal brain function,and early detection of corresponding change trends;

• Sleep-wake cycle monitoring in term and preterm infants;

• Timely detection of subclinical convulsion, epileptic seizure and epileptic state;

• Monitoring the course and efficacy of hypothermia therapy in HIE.

ASSESSMENT

• Assess the therapeutic effects of various interventions;

• Assess the degree of brain damage in patient and improve the accuracy of prognosis;

• Assess the brain maturity in patient;

• Timely conduct clinical intervention in the reversible stage of brain function damage;

• Assist in the assessment of brain death.

Amplitude-integrated ECG (aEEG)

⦁ Intuitive and easily interpreted spectrum

aEEG is a simplified form of continuous recording of EEG.It is to express the change signal of the original brain wave amplitude in semi-logarithmic form after filtering,amplitude integration and time compression,and to reflect the overall level of the background activity of the cerebral cortex

through the upper and lower boundaries of the spectral band.

The upper boundary,lower boundary and bandwidth are three important indicators for analyzing aEEG, and 2h is taken as the optimal duration for spectrum analysis

⦁ Quickly and easily realize brain injury screening, brain function monitoring and brain development assessment in patient,providing effective auxiliary diagnosis reference for clinical treatment;

Automatically identify low voltage and provide tips to help the clinicians adjust the therapeutic regimens in time.

⦁ aEEG background activity pattern identification and classification

According to the amplitude and continuity of the upper/lower boundary of aEEG, the neonatal EEG activity will be classified,and the Hellstrom-Westas background five-classification method will be used to improve the ability of medical staff to identify the aEEG waveforms.

HIE multi-dimensional identification and application

Neonatal ischemic encephalopathy (HIE) is one of the common neurological diseases in the perinatal period and one of the diseases with a high disability rate in the neonatal period.

⦁ aEEG has high sensitivity and specificity for the early diagnosis of HIE patients and the evaluation of the degree of injury (the time window for optimal intervention is within 6 hours of the occurrence of HIE).

Take the neuroprotective measures in time to reduce the mortality and morbidity and improve the accuracy of prognosis.

⦁ Rainbow SET pulse oximetry monitoring

Monitor the SpO2(blood oxygen saturation)/PI(blood perfusion index/PR (pulse)change in a non-invasive and continuous manner,effectively eliminate the exercise interference,improve the measurement performance under low perfusion and body motion,and assist in evaluating neonatal hypoxia to guide the clinical treatment.

⦁ The upgradeable hemoglobin parameter

Perfusion variation index(PVI)enables the clinicians to assess the patient's infusion status, and measure the hemiglobin SpMet in the blood in a non-invasive and continuous manner to assess the blood oxygen content SpOC.

⦁ Burst-suppression,a severe abnormal EEG phenomenon characterized by burst of high-amplitude activity alternating with low voltage or electrical suppression.It can assist the clinicians in measuring bursts per minute (BPM) and interburst interval (IBl)to analyze the brain development of premature infants.

Epilepsy rapid identification and application

aEEG + Envelope Trend Chart (ENVELOPE) + TP + Video

⦁ Envelope trend chart (ENVELOPE) is used to represent the  change in the EEG amplitude, which can better eliminate the artifacts caused by interference and identify epileptic and continuous manner, e ectively eliminate the exercise interference, improve the measurement performance under low perfusion and body motion, and assist in evaluating neonatal hypoxia to guide the clinical treatment. seizure events more accurately.

The envelope trend is considered a reliable method for detecting epileptic seizures. Based on half-wave analysis, it highlights the rhythmic events and filters the transient events. Quickly distinguish epileptic seizures, burst suppression, and comprehensively view the entire process of epileptic seizures for neonatal and child monitoring.

⦁ TP (total power), also known as total energy, reflects the change in the EEG amplitude, and has high sensitivity and low specificity for clinically detecting epileptic seizures.

Convulsion identification and application

EEG + burst-suppression ratio + aEEG + video

Neonatal seizures are often clinically atypical,mostly subclinical and minimal,making it extremely challenging to accurately identify and manage this problem in a busy NICU setting.Patients with convulsions have a very poor prognosis, with a 20%mortality rate in the neonatal period.

⦁ Conventional EEG combined with video monitoring is the gold standard for bedside monitoring.

⦁ Through the rapid identification of suspicious convulsive activity in the aEEG background activity pattern it can improve the ability of medical staff to identify the aEEG convulsive activity pattern,leaving the convulsion identification simpler and faster.

⦁ Single-channel or dual-channel aEEG combined with simultaneous EEG interpretation can increase the detection rate of convulsions.
