CCA-ADVS干预法在儿童无痛牙髓治疗中的应用

Application of computer-controlled anaesthesia with autiovisual distraction of video-eyewear system in pediatric endodontic treatment

112名在我科接受牙髓治疗的4~12岁患儿,交叉随机分别接受计算机控制局部麻醉(CCA)配合头戴式影音装置系统转移注意力法(ADVS)或CCA。复诊时2组互换干预方式。就诊前后对患儿的疼痛、焦虑水平进行评价。结果显示接受CCA-ADVS干预的患儿的疼痛焦虑水平均显著低于同期CCA对照得分(P<0.05),不同时间点得分有统计学差异(P<0.000 1)。提示CCAADVS干预法能有效地控制患儿在局麻中的紧张和焦虑水平。

Eligible 112 children aged 4-12 years old were recruited and assigned to 2 groups with block random design. For the first treatment session, the subjects in group 1 received computer-controlled anaesthesia（CCA） with autiovisual distraction of video-eyewear system（ADVS） intervention based on the routine therapy, those group 2 received only CCA and routine therapy. For the second session, a crossover of intervention methods were conducted for the 2 groups. Before and after each session, pain intensity and dental anxiety of each group were evaluated. Results showed that the group receiving CCA-ADVS presented significantly lower pain intensity and dental anxiety than the group receiving CCA only（P 〈 0.05）. Evident differences were detected in the assessment outcomes in each treatment session（ P 〈 0. 000 1 ）. The combination of CCA and ADVS can effectively reduce pain perception and dental anxiety of children in pediatric endodontic treatment.
