Objective: Viral encephalitis is caused by a variety of virus acute infection.Its clinical manifestation is not typical and illness weight difference is very big.Severe encephalitis can lead to acute death or severe encephalitis legacysequelae. Children viral encephalitis is mainly on the basis of symptoms andsigns combined with EEG, CSF and head MRI and other auxiliaryexamination diagnosis. This research through the understanding of EEG, CSFand head MRI in children with viral encephalitis early positive rate, and thendiscusses the EEG, CSF and head MRI of important value in early diagnosis ofchildren with viral encephalitis and improve the early diagnosis of viralencephalitis, in order to avoid serious complications and complications.Method:1research object:200cases of children viral encephalitis of EEG,head MRI and CSF to set it as the research object, who were hospitalized inthe second hospital of Hebei Medical University from July2013to December2013,including112boys,88girls,Age:5months~13years old; Duration of2~5days.2Research method:200cases of lumbar puncture in children with all dowithin three days. Stay2ml of cerebrospinal fluid, and then send routine,biochemical tests.198cases of children admitted to hospital for3days fromelectroencephalogram room through routine EEG examination.168cases ofchildren admitted to hospital for3days in our image by MRI for inspection.EEG, CSF and head MRI results were statistically analyzed.3Statistical method: EEG, CSF and head MRI results were divided intonormal and abnormal two cases. Statistical results randomly assigned genderand age. To collect and organize EEG, CSF, head MRI results. Sorting theresults and designed: matching four tables. Statistical analyses are done by SPSS13.0Software. P<0.05was statistically significant. The detection rate ofthe two groups is not equal.4Application of antiviral, dehydration in order to reduce brain edema, cool,calm, control of tic and nutrition brain cells treatment. Children with severeapplication immunoglobulin treatment and children breathe through breathingmachine auxiliary treatment for respiratory failure.Results:1198cases: EEG examination was abnormal in166(83.8%), ofwhich130cases (78.3%), mainly for the increasing of the slow wave;36cases(21.7%) were the EEG divided by diffuse or focal abnormal slow-wavebackground activities for features, accompanied by θ、δ wave and sharp,pointed a slow wave, slow spines a syndrome.2200cases: CSF was abnormal in104(52%), mainly characterized bypressure, protein, increased the number of cells, brain pressure heighten43cases (42%), protein increased33cases (32%), and increased cell count of50cases (48%).3168cases:Head MRI was abnormal60cases (35.7%), of which theunilateral limitations were8cases (13.3%), bilateral lesions were18cases(30%),three or more parts of the lesion34cases (56.7%).4116cases of EEG, CSF inspectors at the same time, the EEG abnormalitiesin70cases (60.3%), abnormal CSF26cases (22.4%), abnormal both4cases(3.4%).5100cases of line of EEG and head MRI inspectors at the same time, theEEG was abnormal in70(70%), head MRI was abnormal in52(52%), bothwere abnormal in42(42%).6103cases of CSF, head MRI inspectors at the same time, CSF abnormal in54(52.4%), head MRI was abnormal in31(30.1%), both were abnormal in11(10.7%).798cases of line of EEG, CSF, head MRI inspectors at the same time, theEEG was abnormal in68(69.3%), CSF was abnormal in55(56.1%), headMRI was abnormal in40(40.8%).Comparing the two match four contingency tables party inspection can be found in the following result:1EEG compared with cerebrospinal fluid examination results: x2=28.3, P <0.05,116cases of viral encephalitis in EEG inspectors, a total of116cases(60.3%),70patients with abnormal statistically significant, EEG detectionpositive rate was higher than CSF detection rate.2EEG and head MRI compared: x2=5.98, P=0.014<0.05, inspectors EEGin100cases with head MRI detection rate was statistically significant,positive rate is higher than head MRI shows that EEG detection.3CSF and head MRI compared: x2=5.98, P=0.014<0.05inspectors in103cases of CSF and head MRI detection rate was statistically significant, that thedetection positive rate is higher than head MRI CSF.498cases of line and EEG, CSF and head MRI, line list chi-square testcomparing x2=16.22, P=0<0.05, there is statistical significance.EEGdetection positive rate as high as69.3%.Conclusion: Children viral encephalitis of lack of characteristic clinicalmanifestations, clinical performance combined with auxiliary examination:EEG, CSF and head MRI is the important methods for early diagnosis. EEG,CSF, head MRI is great significance in the diagnosis of viral encephalitis.EEG can earlier, more sensitive response of brain function change. So EEG isthe highest positive rate. EEG is significantly higher than that of CSF, headMRI in early detection. Test positive rate from high to low in turn as the EEG,CSF, head MRI. EEG is important for the early diagnosis of viral encephalitis.
