婴幼儿长程录像脑电图监测电极固定方法的改进及应用效果研究

The fixation method of electrode of improved pediatric video electroencephalogram and its applica-tion effect

目的：确定改进婴幼儿长程录像脑电图监测电极的固定方法是否优于传统固定方法。方法将需要行长程录像脑电图监测的746例患儿按照随机数字表法分为观察组和对照组各373例，2组行长程录像脑电图监测时电极的固定分别采用改进的固定方法和传统的固定方法，以头皮损伤例数、三角肌皮肤损伤例数、电极脱落例数及电极线折损根数为评价指标，评价2种固定方法的优劣。结果观察组发生头皮损伤、三角肌皮肤损伤、电极脱落及电极线折损根数分别为7、0、29例及12根，对照组分别为29、6、71例及37根，2组比较差异均有统计学意义（χ2=14.126、20.371、13.652，P＜0.01或0.05）。结论改进婴幼儿电极固定方法减少了患儿头皮损伤，杜绝了患儿三角肌皮肤损伤，降低了患儿监测中的电极脱落，大大减少了电极线的折损根数，降低了成本支出，减轻了患儿不适。改进后电极的固定方法优于传统组的电极固定方法，值得推广应用。

Objective To determine whether the fixation method of electrode of the improved pediatric video electroencephalogram (VEEG) is better than the traditional fixation method. Methods A total of 746 children patients who needed VEEG monitoring were divided into the experimental group and the control group with random digit table with 373 patients in each group. Improved fixation method and traditional fixation method of electrode were adopted during VEEG monitoring in the experimental group and the control group. The advantage and disadvantage of the two fixation method were compared through evaluation of skin injury of scalp and deltoideus triangularis, electrode loss and electrode breakage. Results The incidence of skin injury of scalp and deltoideus triangularis, electrode loss and electrode breakage in the experimental group were 7, 0, 29, and 12, which were less than 29, 6, 71, and 37 of the control group, the differences were of statistical significance (χ2=14.126, 20.371, 13.652, P<0.01 or 0.05). Conclusions Improved electrode fixation method during pediatric VEEG can avoid skin injury of scalp and deltoideus triangularis, reduce electrode loss and electrode breakage, besides, it also can reduce medical cost and discomfort of children. The modified electrode fixation method proved to be superior to the traditional method and it is worth popularization and application.
