This was to compare the sensation of pain when injections were given using the Wand computer controlled local analgesia (LA) system and a conventional technique in children of pre-school and school age.
38 children were randomly assigned to either a treatment or control group. The treatment (Wand) group consisted of 20 children, while the control group (conventional LA technique) consisted of 18 children. The children were aged between 39.0 and 120.0 months with a mean age of 81.9 months (SD- 23.2). One operator carried out all local analgesia administrations. Pain sensation was rated using the VAS scale by the operator, each child and their parent. Anxiety was rated using the Venham scale.
No statistical difference in pain sensation and anxiety was found when the Wand was used, compared with the conventional technique (P=0.710, P=0.976). The results also showed no significant difference in anxiety change between males and females in the two groups (P=0.714).
There was no difference in the pain or anxiety experienced by the children in the conventional and Wand group.
比较在学龄前和学龄儿童中使用Wand计算机控制局部镇痛（LA）系统和传统技术进行注射时的疼痛感觉。
38名儿童被随机分为治疗组或对照组。治疗（Wand）组由20名儿童组成，而对照组（传统LA技术）由18名儿童组成。儿童年龄在39.0至120.0个月之间，平均年龄为81.9个月（标准差-23.2）。由一名操作人员进行所有局部镇痛给药。操作人员、每个儿童及其父母使用视觉模拟评分量表（VAS）对疼痛感觉进行评分。使用韦纳姆量表对焦虑进行评分。
与传统技术相比，使用Wand时在疼痛感觉和焦虑方面未发现统计学差异（P=0.710，P=0.976）。结果还显示，两组中男性和女性之间的焦虑变化无显著差异（P=0.714）。
传统组和Wand组儿童所经历的疼痛或焦虑没有差异。
