A way to reduce the pain of injection is applying of external cold or vibrations with BUZZY, along with spinal cord gate control systems. We aimed to evaluate the effectiveness of this method in reducing children's pain and anxiety during infiltrative anesthesia.
This was a double-blinded, randomized, split-mouth, controlled, trial. Thirty 6 to 12-year-old children with decayed first permanent molar tooth on both sides of their maxilla were enrolled. Each side of the children's mouths was randomly allocated to either BUZZY or topical anesthetic gel prior to infiltrative anesthesia. Pain and anxiety during infiltrative anesthesia were measured with the Baker-Wong (BWS), FLACC (Face, Leg, Activity, Cry, Consolability), and heart rate (HR) scales.
A generalized estimating equation (GEE) adjusted for age and baseline HR, indicated, significantly-lower intra-procedural HRs associated with BUZZY (aOR [95%CI]: 0.02 [0.00, 0.91], p=0.04). GEEs adjusted for age revealed the BWS (aOR [95%CI]: 0.59 [0.30, 1.14], p=0.12) and FLACC (aOR [95%CI]: 0.82 [0.62, 1.09], p=0.17) scores to be comparable between the study arms.
Our study failed to demonstrate the superiority of BUZZY over anesthetic gels regarding WBS and FLACC measures of pain and anxiety, but demonstrated a decrease in HR associated with BUZZY.
减轻注射疼痛的一种方法是利用外部冷敷或使用BUZZY进行振动，并结合脊髓闸门控制系统。我们旨在评估该方法在减轻浸润麻醉期间儿童疼痛和焦虑方面的有效性。
这是一项双盲、随机、双侧对照试验。纳入30名6至12岁上颌两侧第一恒磨牙龋坏的儿童。在浸润麻醉前，将儿童口腔的每一侧随机分配接受BUZZY或局部麻醉凝胶。使用贝克-王（BWS）、面部、腿部、活动、哭闹、安慰度（FLACC）量表和心率（HR）量表测量浸润麻醉期间的疼痛和焦虑。
经年龄和基线心率调整的广义估计方程（GEE）表明，与BUZZY相关的术中HR显著降低（调整后比值比[aOR][95%置信区间]：0.02[0.00，0.91]，p=0.04）。经年龄调整的GEE显示，研究组之间的BWS（aOR[95%置信区间]：0.59[0.30，1.14]，p=0.12）和FLACC（aOR[95%置信区间]：0.82[0.62，1.09]，p=0.17）评分具有可比性。
我们的研究未能证明在疼痛和焦虑的WBS和FLACC测量方面，BUZZY优于麻醉凝胶，但证明了与BUZZY相关的HR降低。
