Bemmer provocation test

The Pegger hair test means that the cerebral cortex can be excited by Begger, and its intensity is proportional to the dose. High-dose rapid intravenous injection can induce seizures. Although small doses do not induce seizures, they can induce explosive discharges. Wash the hair before the test, do not rub the oil; eat the meal to prevent hypoglycemia from affecting the results; stop the various drugs 3 days before the test, the drug can not be stopped to explain the name, dosage and usage, so that the doctor can refer to. Basic Information Specialist classification: neurological examination classification: neuroelectrophysiology Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: normal. Positive: 1 De-synchronization occurs first, the amplitude of α rhythm gradually decreases, and the fast wave of low amplitude increases. 2 When the injection continues, the amplitude increases, the frequency becomes slower, and σ wave appears; 3 followed by the high amplitude σ wave of burst and bilateral synchronization. Or delta wave; 4 finally spikes, spine slow synthetic waves, paroxysmal discharge. Tips: Wash your hair, don't lick oil; eat well to prevent hypoglycemia from affecting the results; stop the various drugs 3 days before the test. Normal value Normal person is negative. Clinical significance Abnormal result The result is positive. The electroencephalogram of the positive person generally changes in the following order. First, the desynchronization occurs first, the amplitude of the α rhythm gradually decreases, and the fast wave of the low amplitude increases. 2 When the injection continues, the amplitude increases, the frequency becomes slow, and the σ wave appears; Following the occurrence of high-amplitude σ or δ waves in bursts and bilateral synchronization; 4 finally spikes, slow-synchronous waves, and paroxysmal discharges. Need to check the crowd: epilepsy and normal EEG examination Positive results may be diseases: traumatic epilepsy, precautions for pediatric epilepsy Contraindications before the examination: wash the hair, do not lick the oil; full meal, to prevent hypoglycemia affect the results; 3 days before the examination to stop all kinds of drugs, can not stop the drug to explain the name, dosage and usage, so that the doctor can refer to. Requirements for examination: Injection may have side effects, and rest in place for 10 to 20Min. Inspection process 1. Connect the EEG electrodes and record with a bipolar lead. 2. Beimeg slow and uniform intravenous injection, speed: adult 25mg / min, the total does not exceed 150mg (that is, 0.25% Baume 60ml). The total amount of children is 2mg/kg-3mg/kg. 3. Record the EEG from the beginning of the injection and closely observe the changes in the EEG. 4. One of the following conditions occurred in the test immediately to stop intravenous infusion of Bemail, and intramuscular injection of phenobarbital 0.1g-0.2g. (1) The patient has a precursor to seizures. (2) EEG shows spikes, spikes or spine waves. 5. The total amount of intravenous injection of Bemega is 150mg (for 6min), and there is no abnormal change in EEG. EEG should be recorded for 3min, then intramuscular injection of phenobarbital 0.1-0.2, offset by Begme Adverse reactions. Not suitable for the crowd Inappropriate crowd: no Adverse reactions and risks Nothing.
