摘要
目的:观察病毒性脑炎病人的脑地形图特点及临床治疗的指导价值。方法:自2005年2月至2009年3月间对收治资料齐全以儿童为主的53例病毒性脑炎进行BEAM首次描记及追踪观察。结果:53例中轻度异常17例(32%)中度异常24例(45%),重度异常12例(23%)。发病3～5天内阳性率57%,6～8天阳性率88%。BEAM首次描记时间在一周后阳性率及异常程度最高。结论:病毒性脑炎BEAM改变总体表现以广泛不规则高功率θ频带为主,混有部分高功率δ及杂乱波为主。
Objective ： To investigate the clinical characteristics of brain electrical activity mapping （BEAM） on patients with viral encephalitis and explore their directive value in clinical treatment. Methods： The BEAM of 53 patients with viral encephalitis were traced and observed form February 2005 to March 2009,which were mainly children and had intact data. Results： in 53 cases,there were 17 cases （32%） with light abnormal BEAM , 24 cases （45%） with moderately abnormal BEAM and 12 cases （23%） seri- ous abnormal BEAM. The positive rate were 57% （3 - 5 days ） and 88% （6 - 8days ） respectively. The highest positive rate and abnormal extent happened in one week after the first description of BEAM. Conclusions： The characteristics of the BEAM of patients with viral encephalitis were mainly extensively irregular increased 0 power and partial increased 3 power and disorder waves.
