The clinical application of eeg machine in epileptology:


(a) for the diagnosis and differential diagnosis of epilepsy.The diagnosis of epilepsy, there are two essential conditions: (1) the brain dysfunction caused by the onset of clinical symptoms.(2) the electroencephalogram (eeg) check out the epileptic discharge.(2) used for classification of epilepsy.Different types of epilepsy have different eeg manifestations.(3) to assist clinical reasonable selection of antiepileptic drugs and to determine the decrement of antiepileptic drugs and drug withdrawal.(4) used for prognostic judgement.(5) outside the family of epilepsy treatment.Epilepsy surgery is the key to the choice of indications of epileptogenic zone and accurate positioning.Preoperative electroencephalogram (eeg) monitoring is to understand the origin and spread of epileptic seizures, assist epileptic foci of accurate positioning, to provide the reference for selecting the hand surgery way.


Video electroencephalogram (V - EEG) is combined electrical monitoring system and video installation, synchronous recording of seizures in patients with clinical manifestations and electroencephalogram (EEG), the doctor according to the record As data carefully observe the clinical manifestations of the patients with seizures, and synchronization of eeg record contrast analysis, can more accurately determine the beginning of an epileptic seizure types and may, at the same time accurately grasp the state of patients in various periods of activity and the corresponding eeg change, timely discover and eliminate all kinds of interference pseudo differential and electrode failure, improve the veracity and reliability of eeg monitoring results.The following is epileptic eeg monitoring issues related to summarize:


1, epilepsy surgery video eeg examination must be conducted before?


Decisions on refractory, focal epilepsy patients for surgical treatment is the most important factors in assessing before surgical treatment for the patients after different assessment scheme on to judge the results of the source area of the epilepsy.These assessment program include: symptoms, chronic epilepsy seizures break electroencephalography (eeg), episodes of eeg, neuroimaging, all associated with lesions of neuropsychological tests, etc.Long time video electroencephalogram (V - EEG) performance monitoring can provide patients in the bed at the same time attack, attack intermittent period electroencephalogram (EEG) and episodes electroencephalography (EEG), has a pivotal role in the surgical treatment of epilepsy, epilepsy surgery is an indispensable component of preoperative examination.


2, do eeg examination have harm to human body?


Electrical diagram check as a non invasive test, we put the electrode in the body of the scalp, not electricity, head to brain cells group of spontaneity, rhythmic weak electrical signals, through the guidance of electrodes, wires, amplified by eeg machine, filtering and signal processing, such as processing, reflect on a computer screen, get different graphics of electrical activity in the brain, brain to patients to determine.As a result, we know the electroencephalogram (eeg) of the working principle and mechanism, can draw a conclusion: the eeg examination is not only to the human body without any damage, and to understand the patients' condition, timely treatment and recovery are an indispensable means of checking.


3, have done a computed tomography (CT) or magnetic resonance imaging (MRI) examination, why do video electroencephalogram (V - EEG) monitored?


Computed tomography (CT) or magnetic resonance imaging (MRI) is the imaging examination, can only distinguish brain structures with and without exception, imaging examination found that the damage area is not equal to epilepsy.Video electroencephalogram (V - EEG) monitoring can discern the presence of abnormal brain function, can be directly found epilepsy.Eeg examination revealed the epileptic foci sometimes need to confirmed by CT or MRI, can accurate positioning.So the localization of epileptic foci, two check be short of one cannot.


4, video electroencephalogram (V - EEG) monitoring what preparation work to do before?


(1) the doctor inform patients do video eeg examination, inform him to inspect the purpose, time, will check asked to explain to the patient, to eliminate worries of patients, so that the patients can fully understand and cooperate with check, and provide relevant medical history data.


(2) check the patients before the head should be clean, cut short hair when necessary.Do not apply hair oil, wax, moss and other substances.


(3) patients after wards need relatives escort into the video monitoring, alarm at the time of onset and help patients to observe, record and describe the performance of the patients with onset and doctors asking for information.


(4) patients and escort personnel enter the video monitoring ward should turn off the mobile phones, computers, video games and so on, in order to avoid electromagnetic interference affect the accuracy of electroencephalogram (eeg) examination.


(5) in patients with age is too small or cooperation, chloral hydrate oral or enema when necessary.


5, do video electroencephalogram (EEG) (V - EEG) from time to tome what considerations and requirements?


(1) in the video electroencephalogram (V - EEG) monitoring in the process of the bed fence must be set up, in order to avoid accident injury during the attack.


(2) in the video electroencephalogram (V - EEG) during the process of monitoring, patients with all the activities should be controlled in the range of the camera and keep the electrode wire connection is reliable to ensure the quality of the V - EEG monitoring.


(3) in monitoring ward is not play, noise, and play, and keep the room quiet and comfortable.


(4) the attendants, not sleeping with patients.Onset in patients with ring should immediately report to the police escort personnel, don't press, pulling the patient, don't keep out camera, at the same time open the lid of the patients is to facilitate the performance of the attack were observed, and pay attention to the safety of the patients.Detailed records patients condition and time during the attack in a timely manner.


(5) the patient when the nurse symptoms should immediately in place to observe, and open the quilt note whether blocking shots, close observation and clinical manifestations, observation of patients consciousness, at the same time the patient's head turned to one side, remove the pillow, in case of patients with respiratory tract obstruction.Completes the related records in a timely manner.


(6) patients after should immediately give oxygen, critical condition should inform the doctor gives processing.


(7) eeg monitoring personnel should be regularly patrol monitoring room, in a timely manner to understand the patient attack situation, check the electrode wire connection status.


(8) eeg monitoring personnel deal with patients, and the record of continuous, close and direct monitoring, so that you can quickly identify set for event and eeg records of technical failure.In case of special and suspicious condition should be record, hence the effective and detailed test results will be obtained in the diagnosis of epilepsy and epilepsy to district positioning has important significance.
